Description

The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, apparatus, and system. BACKGROUND OF THE INVENTION With the rapid development of wireless communications, the demand for frequency bands continues to increase, and the demand for frequency bands by 2010 will be 200% to 300% in 2002. Since the existing band allocation strategy is fixed, the spectrum is not fully utilized. For example, according to the FCC (Federal Communications Commission) report, it can be seen from the two-dimensional statistics of time and space that the utilization rate of existing allocated spectrum is only between 15% and 85%. The wireless band is a scarce resource that is very expensive to manufacture. This also requires wireless communication technology to improve utilization. Currently, the use of spectrum in mobile communications is mainly to allocate limited spectrum resources to different operators through the auction of spectrum resources or through government allocation. How to maximize the use of these spectrum resources by these operators and improve spectrum utilization, the industry has proposed some solutions. One of the more common methods of processing is to share spectrum resources between different systems through a spectrum server and a spectrum broker. For example, after the spectrum resource is allocated to the spectrum owner, the spectrum owner stores the spectrum resource in the spectrum server, and the spectrum server provides the spectrum resource to the spectrum purchaser who finally uses the spectrum resource. The spectrum purchaser is a system or an operator that actually provides a mobile communication service, and can initiate a spectrum resource request to the spectrum owner, specifically to the spectrum owner's spectrum server, in real time, and bid for the spectrum resource according to the auction principle; The spectrum server can allocate spectrum resources according to the results of bidding by multiple spectrum buyers, that is, spectrum resources are obtained by the spectrum buyers with high bids. In this processing mode, spectrum purchasers can purchase and release as needed, realizing the sharing of spectrum resources among multiple systems or operators, improving spectrum utilization, and avoiding a lot of operators or systems. The use of spectrum resources is rarely used. However, this scheme will result in a large delay in the allocation of spectrum resources, because spectrum buyers are required to initiate spectrum bidding and spectrum requirements. After the spectrum server receives it, it is necessary to compare different bids, and there may be multiple bids. The spectrum resource information is then notified to the spectrum purchaser, and the spectrum purchaser allocates the spectrum resource to the access device of the system. This kind of bidding process can be complicated, requiring multiple spectrum buyers to bid multiple times, which is difficult to automate, and this kind of bidding method is difficult to allocate resources flexibly, resulting in low resource utilization. Another common approach is to implement network sharing among operators, for example, to achieve access network sharing or roaming-based sharing. These two sharing methods usually involve a sharing agreement between operators, which stipulates various fees and divisions. That is to say, in the two sharing modes, the cost of different operators' services and the proportion of resources occupied are all stipulated in the agreement. Since it is a predetermined ratio of resources, it is easy to cause the resource utilization rate to be low. For example, Carrier B has more current services. Although Carrier A currently has fewer services, Carrier B cannot use Carrier A's resources. If you need to change the resource allocation, you must negotiate a new protocol, which obviously makes the sharing less flexible. In summary, the current resource allocation methods are not flexible enough, resource utilization is not high, and the degree of automation of resource allocation is low. SUMMARY OF THE INVENTION The main technical problem to be solved by various embodiments of the present invention is to provide a resource allocation method for flexibly allocating various resources.

In another aspect, a wireless communication system is further provided, including: a centralized controller, and at least two network access devices, where different network access devices correspond to different networks or operators. The centralized controller is configured to obtain pricing information of a resource usage object in each network or each operator, and send the obtained pricing information to a network access device corresponding to each network or an operator; Determining, according to the pricing information of the resource usage object in each network or the operator, the total pricing information of the corresponding network access device, and allocating resources to each network access device according to the total pricing information of each network access device and sending the information to the network access device Each network access device is configured to: according to the pricing information of the resource use object in the network access device sent by the centralized controller, and the centralized controller is allocated to the network access Resource of the device, which is the resource in the network access device Use objects to allocate resources. Embodiments of the present invention allocates resources for resource use objects according to the pricing information, so that operators can flexibly price resource use objects according to needs, and the network side can flexibly allocate resources according to pricing. This enables the network side to allocate various resources more flexibly, and also improves resource utilization on the network side. And this way of allocating resources according to pricing, it is completely simple and easy to carry out resource allocation automatically.

The related information of the resource use object can be the importance of the resource use object, the revenue, the cost, the operator's operation strategy, and the resource use object in the carrier. The ratio of revenues in the market, etc. Status information of wireless resources, Then, the usage state of the wireless channel occupied by the resource usage object, whether the network is congested, the degree of congestion, the channel quality, the cell load status, the neighbor cell information, etc. The resource usage object may be a mobile terminal or a user, or It is a service. The processing method is the same for each specific object. Therefore, the following mainly describes the mobile terminal as an example. In a specific implementation, the information required for pricing may be measured by the network side when the mobile terminal accesses, for example, one or more of the usage status of the wireless channel occupied by the mobile terminal, congestion, congestion level, channel quality, and the like. Information. Thereafter, the pricing for the mobile terminal can be determined based on the information, and/or based on relevant information of the mobile terminal, such as the importance of the mobile terminal, business revenue, cost, and the like. In addition, during the operation of the system, the network side can also report changes in channel quality in real time, and the system can adjust the pricing in real time according to the information. Step 104: The access network device allocates resources for the resource usage object according to the received pricing information. The access network device can use the pricing information as a resource scheduling parameter to allocate resources to the resource usage object of the operator. The resource may include a spectrum resource, and may also include a transmit power of a signal, a device, and the like. Specifically, the resource usage object may be allocated resources in descending order of the pricing information of the resource usage object. As mentioned above, the resource usage object may be a mobile terminal, a user, or a service. For a variety of specific objects, the processing method is the same. Therefore, the following is mainly described by taking a mobile terminal as an example. For the processing of users and services, details are not described herein again. In the specific implementation, it is possible to use formula (0). :* = max{Q( } formula (0)

k where C _k (t) is the pricing information of the mobile terminal k. Using the formula (0), specifically, determining the mobile terminal corresponding to the maximum value, allocating resources for the determined mobile terminal k*, and then removing the mobile terminal k* from all mobile terminals, according to formula (0) Allocate resources to other mobile terminals. Subsequent processing is analogized until resources are allocated for all mobile terminals. In addition, in the above step 104, when the access network device allocates resources, the access state information, QoS (Quality of Service), and the like of the radio channel occupied by the resource use target may be further considered. For example, the resource can be used for a resource with a high price and a good use state of the wireless channel, and the resource is preferentially allocated, or the resource is used with a high price and a high latency requirement of the QoS, and the resource is preferentially allocated. The access network device may also consider pricing information when establishing a radio bearer before performing resource allocation. For example, the priority of the radio bearer may be determined for each resource use object according to the level of the pricing information; the resource may be used for the resource with high pricing, and the resource of the resource using the low-priced resource may be preempted. Similarly, access network devices can also consider pricing information when establishing connections or performing mobility management. For example, it is possible to establish a connection or implement a handover for a resource-used object with a high price. It is also possible to set a resource-used object with a high price to preempt a resource of a resource-used object with a low price. Of course, if it is determined that the resource usage object with high pricing is preferentially switched, the specific handover operation should be performed after the resource allocation of the above step 104. The access network device can also consider pricing information when accessing the control. For example, a resource-used object with a high price can have a high access priority and can preempt resources of a resource-used object with a low price. In addition, the access network device may also determine whether the overall revenue of a certain cell is greater than its neighboring cell. If it is greater, the resource usage object of the cell edge may be switched to its neighboring cell, or the cell with a large overall benefit may be improved. Transmit power. The overall revenue may be determined according to the pricing of the resource usage object accessing the cell. The reason why the overall revenue of a certain cell is large is because the overall revenue of a cell is large, indicating that the resource usage rate of the cell is already relatively high. To fully utilize the resources of the system, some resources may be used. The use object switches to a neighboring cell with a small overall benefit, so that these resource use objects can use the resources of the neighbor cell. In addition, it is also possible to obtain resources for a high-level resource use object in the neighboring cell with small revenue by switching, and the high-level resource use object is a resource use object with high pricing. In the above manner, the operator only priced according to the resource use object, and does not price the spectrum resource or other resources, so as to avoid the problem of large delay and low efficiency caused by the method of pricing the resource. At the same time, the access network device considers the pricing factor in the resource scheduling, so that the pricing information affects the scheduling of the shared resource, and the resource scheduling can be dynamically adjusted according to the adjustment of the pricing, so that the allocation of the shared resource is more flexible. For operators that request multiple resources, considering the pricing factor in the resource allocation, the resource can be preferentially assigned to the operator with the highest price, thereby maximizing the resource value. Moreover, the operator can perform dynamic pricing according to requirements, which makes the pricing more accurate, and avoids the problem that the pricing of the channel resources corresponding to the spectrum resources is inaccurate after the operators in the prior art price the spectrum resources. In addition, since the use state information of the wireless channel used by the resource use object in the network can also be considered when allocating resources, it is also ensured that the channel can be allocated to the resource use object with good channel quality as much as possible, thereby improving system traffic. Moreover, if the channel usage status is updated, resource allocation may be re-allocated according to the updated channel usage status, thereby implementing dynamic adaptation to channel quality changes. The following is an example of an LTE (Long Term Evolution) system, which is described in a specific embodiment.

The spectrum resource allocation scheme of the present invention is implemented in an LTE system. Those of ordinary skill in the art will appreciate that other communication systems The implementation of the system is similar to that of the LTE system, and therefore will not be described in detail. In addition, as described above, in order to simplify the description, the mobile terminal is uniformly used here to represent an object that needs to allocate resources, but it is clear that the objects that need to allocate resources include mobile terminals, users, services, or other descriptions, which are implemented in the present invention. There is no essential difference in the example. In the LTE system, the pricing operation of step 101 above may be performed by the core network device of the LTE, and the resource allocation operation of the above step 104 is performed by the access network function entity of the LTE. In an LTE system, channel resources are allocated based on a resource block (RB). It is assumed that there are N RBs and K mobile terminals in one cell of the system, and one mobile terminal can be allocated multiple RBs at one time, but one RB can only be allocated to one mobile terminal. Is the channel rate of mobile terminal k on RBn at time t. Assume that the operator's pricing for the mobile terminal k is G (0, which is called the pricing factor, then the resource allocation can be calculated according to the "(0 and C _fc (t). See equation (1) for details.

^∑∑R _k ⁿ (t) _k (0 formula ( ₁ )

Kn can determine the RBs allocated to the mobile terminal k among the N RBs and K mobile terminals by using the formula. Specifically, the mobile terminal k can be calculated by the formula (1), and one or the maximum value is calculated. A plurality of RBs are allocated to the mobile terminal. At the same time, it is also necessary to satisfy the allocation condition that one RB can be allocated to one mobile terminal at a time, but one RB can only be assigned to one mobile terminal. In the embodiment of the present invention, the pricing factor is introduced into the resource allocation of the access network device, so that the mobile terminal or the service with high pricing obtains a greater opportunity for resource allocation, and if the pricing of the mobile terminal or service changes, or the operator If it is desired to change the pricing of the mobile terminal or service, the system can reallocate the resource in time according to the pricing, so that the resource can be allocated more flexibly; the allocation also considers the channel quality factor, that is, the above 3⁄4"W, so the system is When the resources are allocated, the channel state can be considered, so that the spectrum resources can be fully allocated. In addition, the fairness factor between different mobile terminals can also be considered, that is, the channel cannot be completely allocated to the mobile terminal with good channel quality, and the cell is avoided. The mobile terminal at the edge or the mobile terminal with poor channel quality can not get the transmission opportunity. It can be called proportional fairness. Still taking the LTE system as an example, the average rate that the mobile terminal has allocated can be used as the calculation factor, and the sum is t) the calculation of the resource allocation. The average rate is called a proportional fairness factor, denoted by T _k (t), we can make use of the equation (2) for computing the resource allocation. R _k ⁿ {t)C _k jt)

Formula ( 2 )

T _k {t) The RB is allocated to the mobile terminal k by the formula (2), which is similar to the foregoing formula (1), and details are not described herein again. T _k (t) in the above formula (2) can be specifically calculated by the formula (3).

(l --)T _k (t) + -R (t), k = k

+i) = formula (3)

(l -) T _k (t), k ≠k where k ⁴ represents the selected mobile terminal number and ς is the window of the proportional fairness factor. The RB number assigned to the mobile terminal can be represented by η*. The formula (3) indicates that when an RB is allocated to the mobile terminal, the proportional fairness factor T _k (t) represented by the mobile terminal is also updated, that is, a rate "« is added; when a mobile terminal is not allocated In the case of RB, it is necessary to reduce the proportional fairness factor. Thus, the more RBs allocated by a mobile terminal, the more the proportional fairness factor increases, and the less likely to be assigned to the RB next time, otherwise the next time it is allocated. The more opportunities to RB, the greater the unfair distribution of resources is avoided. For wireless communication systems, there are usually multiple networks at the same time, such as GSM/WCDMA/LTE. These networks may be provided by the same operator or by different operators. There may be only one type of network, but they are provided by different operators. For the sake of distinction, the networks provided by different operators are seen. Different networks. For the above cases, an access network device can be set for all networks or operators during specific implementation. The implementation is as described above. Since the method for setting the access network device is similar to the network or the operator, therefore, in the description of setting the multiple access network devices, the access network device is mainly used for the network. The settings are described as examples. Different access network devices can be set for different networks. For example, set the base station controller for the GSM network, set the RNC for the WCDMA network, and set the e B for the LTE network. For the sake of distinction, these are different. The network access device is called a network access device. It is also possible to set a centralized control device, called a centralized controller (C-Controller), through which the centralized controller adjusts the resource allocation of each network according to the pricing of different networks. The C-Controller can also be considered as an access network device. For the case of setting multiple access network devices, in the above step 101, the pricing information is sent to the access network. The device may specifically send the pricing information of the mobile terminal in each network to the C-Controller, and the C-Controller then sends the pricing information of the mobile terminal in each network to the network access device of each network. After the step 101, before the step 104, the method further includes: determining, by the C-Controller, the total pricing information of the network according to the pricing information of the mobile terminal in each network, for example, weighting and accumulating pricing information of each network, The obtained weighted value is used as the total pricing information of the network, and system resources are allocated to each network according to the total pricing information. Its specific allocation scheme is similar to step 104. For step 104, each network access device may allocate resources to the mobile terminal according to resources allocated by the C-Controller to the network. Of course, if the pricing information needs to be determined according to the state of the wireless resource, the network access device of each network or the operator may also report the status information of the wireless resource of the local network or the carrier to the C-Controller. The network access device reports the usage status information of the radio resources of the local network, and may specifically integrate the radio resources of the network or the carrier according to the status information of the radio resources occupied by the mobile terminals in the network or the carrier. The status information is sent to the C-Controller. The network access device directly reports the status information of the radio resources occupied by each mobile terminal, and is integrated by the C-Controller. After that, the operator can determine the overall pricing standard of each network according to the state of the radio resources of each network. For example, if the channel state of the GSM network is good, the operator can determine that the mobile terminal in the network can be higher. The pricing can be made lower. Otherwise, when the mobile terminals in the GSM network are priced, the pricing of the wireless resources occupied by the mobile terminals can be separately priced. If additional information is required for pricing, the processing scheme is similar to pricing based on the status information of the wireless resource. The general principle is that it is necessary to determine the situation of each network, for example, determining status information of radio resources in each network and/or related information of mobile terminals in each network, and determining overall pricing standards between networks according to the information; In each network, according to the situation of each mobile terminal, for example, according to the state information of the radio resources occupied by the mobile terminal in the network and/or the related information of the mobile terminal, of course, it is also required to be based on the overall pricing determined for each network. Standard, pricing each mobile terminal. In the embodiment of the present invention, the foregoing step 101 may be implemented by an operator pricing device. For setting up the operator pricing device, you can set one only one; you can also set one for the same carrier; you can also set it separately for different networks, or you can set it separately for different operators. Various arrangements will not affect the implementation of the present invention. The operator pricing device can also be connected to the core network charging device and the access network device respectively. The core network charging device sends a pricing parameter to the operator pricing device, and the pricing parameter may be a revenue ratio of the mobile terminal in the operator, and revenue information of each operator. The operator pricing device can price the mobile terminal among the operators according to the pricing parameter. After pricing the operator pricing device, the pricing information can be sent to the access network device. In addition, the operator pricing device may further receive channel state information sent by the access network device, and price the mobile terminal in each operator according to the channel state information and the pricing parameter. Of course, if there are multiple operators, the operator may have multiple pricing devices, and different operator pricing devices correspond to different operators. In this case, the core network charging device can set the pricing of each carrier. The parameters are sent to the corresponding operator pricing equipment. Correspondingly, the access network device also needs to send channel state information to each operator pricing device. The apparatus and system embodiments of the present invention are described in detail below. As shown in FIG. 2, the access network device may include an information acquiring module 201 and a resource allocating module 204. The information obtaining module 201 is configured to obtain pricing information for the resource usage object, and the resource allocation module 204 is configured to allocate resources for the resource usage object according to the pricing information acquired by the information acquiring module. The pricing information acquired by the information acquiring module 201 may be specifically determined according to state information of the wireless resource occupied by the resource using object and/or related information of the resource using object. The status information of the radio resource and the related information of the resource use object may be specifically described above, and are not described herein again. For the LTE system or the like, the resource allocation module performs resource allocation according to the pricing information, and specifically, may allocate resources for the resource use object according to the order of the pricing information; or may be according to the foregoing formula (1) or formula (2) The maximum value is calculated, and the RB corresponding to the maximum value satisfies an RB that can allocate a plurality of RBs to one resource use object at one time, and one RB can only be allocated to one resource use object, and is allocated to the RB. Resource usage object. Also, T _k (t) in the formula (2) can be given by the above formula (3). The access network device may further include a plurality of network entities, where the network resource allocation module of the access network device may further set a processing rule for accessing and/or switching of the resource usage object before the resource allocation module of the access network device performs resource allocation. . For example, you can set one or more of the following network entities. Set the first network entity. The first network entity may be configured to use an object for a high-priced resource to preferentially establish a radio bearer; and set a second network entity. The second network entity can be used to set a resource with high pricing to be able to preempt A resource with a low price is used by the resource of the object; a third network entity is set. The third network entity may be configured to preferentially establish a connection to the resource-used object with high pricing; and set a fourth network entity. The fourth network entity may be configured to determine an overall revenue of the cell according to the pricing of the resource usage object in the cell, and switch the resource usage object in the cell of the neighboring cell to the neighboring cell; and set the fifth network entity. The fifth network entity may be configured to determine an overall revenue of the cell according to a pricing of the resource usage object in the cell, and improve an overall benefit that is greater than a transmit power of the cell of the neighboring cell. For the network entity for the resource usage object, after the network entity performs the corresponding operation, a corresponding message is sent to the resource allocation module, for example, the first network entity may send a radio bearer setup complete message; the second network entity A notification message that the resource can be preempted can be sent; the third network entity can send a connection setup complete message; the fourth network entity can send a handover complete message. After receiving the messages, the resource allocation module can perform the processing of resource allocation. For the foregoing fifth network entity, the resource allocation module may not send a message. Of course, the transmit power adjustment message may also be sent, and the resource allocation module may perform resource allocation after determining that the transmit power of the cell is improved according to the message. Of course, it is also possible to directly allocate resources for resource usage objects regardless of whether the transmission power is adjusted or not. A sixth network entity may also be added, and the network entity may be used to preferentially switch the resource usage object with high pricing; correspondingly, the handover should be performed after the resource allocation module allocates resources. For the LTE system, as shown in FIG. 3, the core network device is usually a Mobility Management Entity (MME), and the access network function entity may include an eNB, and the eNB may further include an inter-cell RRM (Inter Cell RRM), Radio Bearer Control (RB Control), Connection Mobility Control (CMC), Radio Admission Control (RAC), Dynamic Resource Allocation Schedule, etc. Therefore, for the LTE system, the access network device may be an eNB, and the first network entity and the second network entity may be RB control; the second network entity may be a RAC; the second, third, and The six network entities may each be a CMC; the fourth network entity and the fifth network entity may both be inter-cell RRMs. For example, take a mobile terminal as an example. For the RB control, the pricing parameters can be taken into consideration when establishing the radio bearer. For example, the priority of the radio bearer can be adjusted according to the pricing parameter, and the mobile terminal with high pricing can be set to occupy the mobile terminal with low pricing. Resources, etc. For RAC, when performing mobile terminal access control, the pricing parameter can be used as a calculation factor, and a highly priced mobile terminal has high priority access and can preempt the connection of a low-priced mobile terminal. For the CMC, pricing parameters are considered when establishing a connection or mobility management. For example, a mobile terminal with a high price is preferentially established to establish a connection or implement a handover, and a mobile terminal with a high price can seize the resources of a mobile terminal with a low price. For inter-cell RRM, if the overall revenue of a cell is greater than its neighboring cell, the mobile terminal at the cell boundary may be handed over to its neighboring cell, or the transmit power of the cell with a large overall benefit may be improved. It is thus possible to make full use of resources by switching some mobile terminals to neighboring cells with low overall revenue. In addition, it is also possible to obtain resources for a high-level mobile terminal in the neighboring cell with small revenue by handover. The above solution introduces pricing information into the functional entities of each access network device, so that the operator can indirectly control the resources occupied by the operator through pricing, that is, if the pricing of the mobile terminal under the operator is high, the operator can occupy More resources. At the same time, it can also combine the factors usually considered by the functional entities of the access network device such as QoS and wireless channel quality, so that the resource allocation can adapt to the changes of QoS and wireless channel quality. For example, for QoS, when the resource is allocated, according to the delay specified in the QoS, the transmission priority of the data with high delay requirement is set to be high under the premise of the same price, and accordingly, the data is correspondingly The transmission priority of the relevant mobile terminal is also high. For the radio channel quality, as described above, the priority of the mobile terminal with good radio channel quality can be set to be high. The processing may be specifically implemented by inter-cell RRM in an LTE system. In addition, as mentioned above, there are usually multiple networks in the system, for example, GSM/WCDMA/LTE, etc. There are also multiple operators. Different access network devices can be set for different networks or different operators. For example, a base station controller is set for the GSM network, an RNC is set for the WCDMA network, and e B is set for the LTE network. For the sake of distinction, these access network devices for different networks are referred to as network access devices. It is also possible to set a C-Controller through which the resource allocation of each network is adjusted according to the pricing of different networks. Correspondingly, the wireless communication system of the embodiment of the present invention may specifically include at least two network access devices 401 and a centralized controller 402, as shown in FIG. The resource usage object is still specifically taking a mobile terminal as an example. The centralized controller 402 can be configured to obtain pricing information of the mobile terminal in each network or each operator; and send the obtained pricing information of the mobile terminal in each network to the network access device 401 of each network. The centralized controller 402 can also be configured to determine the network according to pricing information of the mobile terminal in each network. The total pricing information is allocated to each network access device 401 according to the total pricing information of each network or operator; and is also used to send the allocated resources to each network access device 401. Here, the centralized controller 402 allocates resources for the network access device, which is actually equivalent to allocating resources for the network or operator corresponding to the network access device 401. Each network access device 401 can be used to allocate resources to the mobile terminal according to the pricing information of the mobile terminal sent by the centralized controller 402 and the resources allocated by the centralized controller 402 to the network access device 401. Each network access device may specifically include the information acquiring module and the resource allocation module shown in FIG. 2 . The information obtaining module is configured to receive pricing information sent by the centralized controller, and is also used to receive resources allocated by the centralized controller for the network. The resource allocation module allocates resources for the corresponding mobile terminal according to the pricing information sent by the centralized controller and the resources allocated by the centralized controller for the network. It is obvious that each network access device can also perform various specific implementations in the foregoing embodiments. Of course, each network access device may further include one or more of the foregoing first to fifth network entities. The specific implementation is the same as the specific implementation of the foregoing access network device, and details are not described herein again. For the above-mentioned centralized controller, when allocating resources for each network access device, in addition to referring to the total pricing information of each network, reference may also be made to the wireless channel status, QoS, and the like of the network. Each network access device is similar. In the centralized controller, the status information of the radio resources occupied by each mobile terminal collected by each network access device may be received, the radio resource status of each network is determined according to the information, and the radio resource status and each network are determined according to the information. Total pricing information to determine the resources allocated for each network. As described above, the state of the radio resources of each network may be determined by each network access device according to the state information of the radio resources occupied by each mobile terminal, and the status information of the radio resources of the network access device is determined and reported to the centralized control. The state information of the radio resources occupied by each mobile terminal may be directly reported by the network access device, and the centralized controller determines the state information of the radio resources of each network access device according to the information. Similarly, the network access device may allocate resources to the corresponding mobile terminal according to information such as the state of the radio resources occupied by each mobile terminal, the pricing information of the mobile terminal, and the resources allocated by the centralized controller for the network. For the system of the present invention, as shown in FIG. 5, an operator pricing device 403 may also be included, which is priced by the operator pricing device. Specifically, it may be formulated based on related information of the mobile terminal, and may also be determined according to status information of the wireless resource used by the mobile terminal. Of course, the two pieces of information may also be considered at the same time. The specific implementation of pricing is as described above, and will not be described here. In the case of various information as a pricing factor, the operator pricing device first needs to obtain this information, and then pricing. If there is only one access network device, the operator pricing device directly obtains the state information of the wireless resource reported by the access network device and/or the related information of the mobile terminal, and priced the corresponding mobile terminal according to the information. In the case of multiple access network devices, that is, when there are multiple network access devices and there is a centralized controller, the network access device may use the centralized controller to change the state information of the wireless resources of the network and/or The relevant information of the mobile terminal is sent to the operator pricing device, and the operator pricing device can directly price the mobile terminal according to the information. The operator pricing device may also determine the overall pricing standard between the networks according to the status information of the wireless resources of the network and/or the related information of the mobile terminal determined and reported by the network access device in each network; Each mobile terminal is priced according to the overall pricing standard between the networks, and the status information of the wireless resources of each network and/or related information of the mobile terminal. When the pricing device of the operator is pricing, if the charging-related information such as the revenue ratio of the mobile terminal in the operator needs to be used, the operator pricing device may also be connected to the charging device of the system, and the charging device is connected. The information such as the proceeds is sent to the operator pricing device, and the operator pricing device can also send the pricing information to the billing device. The billing device can adjust the billing according to the pricing information. In addition, for the above-mentioned operator pricing equipment, the operator may have only one pricing device, or may be separately set for different networks, or may be separately set for different operators. The various implementation schemes do not affect the implementation of the present invention, except that if there are multiple operator pricing devices, the information is sent to the corresponding carrier pricing device when the information is exchanged. In summary, for the embodiments of the present invention, the operator only priced according to resource usage objects such as mobile terminals, services, users, etc., and does not price spectrum resources or other resources, thereby avoiding pricing of resources. The way of delay and efficiency is brought about by the way. At the same time, the access network device considers the pricing factor in the resource scheduling, so that the pricing information affects the scheduling of the shared resource, and the resource scheduling can be dynamically adjusted according to the adjustment of the pricing, so that the allocation of the shared resource is more flexible. For operators that request multiple resources, considering the pricing factor in the resource allocation, the resource can be preferentially assigned to the operator with the highest price, thereby maximizing the resource value. Moreover, the operator can perform dynamic pricing according to the requirements, which makes the pricing more accurate, and avoids the inaccurate pricing caused by the change of the channel quality corresponding to the spectrum resource after the operator allocates the spectrum resource in the prior art. The problem. In addition, since the state information of the radio resources occupied by the resource use objects in the network can be considered when allocating resources, it is also ensured that the channel can be allocated to the mobile terminal with good channel quality as much as possible, and the system traffic is improved. Moreover, if the channel usage status is updated, the resource allocation may be re-allocated according to the updated channel usage status, thereby realizing dynamic adaptation to channel quality changes. It is also possible to consider the fairness factor between different mobile terminals, that is, the channel cannot be completely allocated to the mobile terminal with good channel quality, and the mobile terminal at the cell edge or the mobile terminal with poor channel quality cannot be prevented from transmitting. It will be understood by those skilled in the art that all or part of the steps of implementing the above method embodiments may be completed by a program instructing related hardware, and the program may be stored in a computer readable storage medium, and the program is executed. The foregoing may include the contents of the various embodiments of the present invention. The storage medium referred to herein is, for example, a ROM/RAM, a magnetic disk, an optical disk, or the like. While the invention has been illustrated and described with reference to the preferred embodiments embodiments The spirit and scope of the invention.
