Description

Method, device and system for implementing split transmission in multi-standard wireless network

The present invention relates to wireless communication technologies, and more particularly to a method, apparatus and system for implementing split transmission in a multi-standard wireless network. Background technique

Long Term Evolution (LTE) is a 3G network evolution technology and is a wireless access network technology after 3G. The LTE network has only one node on the access network side, namely eNodeB (Evolved NodeB), and the physical PHY layer and MAC layer of the air interface terminate here. It has automatic retransmission ARQ, hybrid automatic retransmission HARQ, radio resource management RRM, and radio resources. Control functional entities such as RRC. The core network side (referred to as aGW-access gateway) includes a mobility management entity MME and a user plane entity UPE.

World Microwave Access Interoperability WiMA ^ 802.16 a wireless access network technology, 802.16 based WiMAX network model shown in Figure 1, including user terminal, access service network ASN and connection service network CSN three logic entity. The ASN manages the IEEE 802.16 air interface and provides wireless access for WiMAX users. The ASN is composed of at least one base station BS and one ASN gateway (GW), and one ASN may include a single ASN-GW or multiple ASN-GWs. The reference model of the ASN is shown in Figure 2 and Figure 3. In Figure 3, one BS is logically connected to one or more ASN-GWs.

At present, the GSM system uses time division multiplexing TDM transmission and only provides voice services. Although the transmission performance is good (low delay), a clock signal can be provided for the base station to use, but for the operator, the E1 line is often rented, and the cost is very high.

Considering the demand for data services in the future market, it is highly likely that a multi-standard access network will be adopted. A multi-standard access network means that multiple wireless access systems (technologies) are uniformly implemented on the same network element (mainly referred to as a base station), and different wireless access systems use a part of devices (such as antennas, radio frequency boards, etc.), and only various The parts of the wireless access system that must be handled separately are separated (such as the baseband processing part). This has the advantage that operators can increase the cost of multiple service services while saving as much as possible.

When implementing a multi-standard base station, it is highly probable that other wireless access technologies will be added on the basis of GSM. Such as: Add WiMA and / or LTE based on GSM. In this scenario, in addition to the services required for signaling and high latency, it is not necessary to use high-performance El for other service data, and it is highly probable that public IP transmission will be used because of the high cost performance. This means that the multi-standard access network is likely to have a split transmission.

The current multi-standard access is only for how different air interface transmission technologies are integrated and how to uniformly allocate air interface resources. The split transmission proposed by the industry is for a base station supporting a single access system. For example, the NodeB has two interfaces: The interface transmits data through ATM/E1, and the other interface transmits data through IP/FE (Fast Ethernet), and finally merges in the wireless network controller. This solution not only creates obstacles for device interworking of different providers, but also does not consider how to deal with new problems in multi-standard mode: For example, LTE only has two layers of nodes (eNodeB and aGW), how to correspond to the three layers of GSM Point and other questions.

Therefore, when implementing multi-standard (under the common site) on one base station, it is necessary to provide a new scheme to effectively optimize the configuration and utilize the network side transmission resources. Summary of the invention

In this embodiment, a multi-mode base station supporting multiple radio access systems in a multi-standard access network accesses user equipments of different radio access systems to the network, and the multi-mode base station and other network nodes are paired. When transmitting data, the transmission network is selected from multiple transmission networks to implement split transmission (or hybrid transmission) of data in the access network. The multi-mode base station (or multi-standard base station) in this embodiment refers to a logical base station corresponding to multiple access technologies, which includes base stations formed in the same node device, and these logical base stations can share part of device resources, such as node devices. Backplane bus, CPU of the node device, memory of the node device, and even some board resources. The device on the same node can be physically expanded. For example, the capacity of the node device is expanded by stacking the chassis. The network node in this embodiment includes a multi-mode base station and an upper node of the multi-mode base station.

The multi-standard access network in this embodiment refers to that multiple radio access systems (technologies) are uniformly implemented on the same network element (mainly referred to as a base station), and the split-channel transmission refers to the radio access network side for the wireless access system and / or different data types, respectively, using different transport network layer technologies (mainly different between the physical layer and the data link layer) to transmit data.

In this embodiment, multiple radio access systems include a radio access system corresponding to a global mobile communication system GSM network and/or a UMTS network (including WCDMA and CDMA2000), and a long-term evolution LTE network, a WiMA network, and high-speed packet access. HSPA evolves some or all of the wireless access systems in the wireless access system. The following is an example of adding an LTE access network technology or adding a WiMA access technology based on an existing GSM network or a UMTS network. The transmission is described. For convenience of description, the following "base station" refers to a BTS of GSM or a NodeB of UMTS, "base station controller" refers to a BSC of GSM or an RNC of UMTS; and a core network CN refers to a core network of GSM or UMTS. The time division multiplexing TDM refers to a time division multiplexing transmission system, and the transmission system can provide a clock signal to the network element.

An example of a network structure that adds LTE access network technology to the GSM network is shown in Figure 4. The network system in this example includes a multimode base station 40, a base station controller 41 of GSM, a core network CN42 of GSM, and an access gateway aGW44. The multimode base station 40 is connected to the base station controller 41 via a TDM transmission network 43 (i.e., E1 physical medium), and to the access gateway aGW 44 via an IP transmission network 45; the base station controller 41 is connected to the core network 42 and the access gateway 44, respectively. . The multi-mode base station 40 has a GSM BTS400 and an LTE eNodeB 401. The BTS 400 is responsible for accessing the GSM user equipment, and the eNodeB 401 is responsible for accessing the LTE user equipment.

In the network system shown in Fig. 4, the data is branched and combined by the multimode base station 40 and the access gateway 44. The base station 40 performs the shunt processing on the uplink data according to the access system and/or the service attribute, that is, the TDM transmission network 43 or the IP transmission network 45 is selected to forward the uplink data, and the downlink data is combined and processed, that is, from the TDM network 43. The LTE data transmitted by the IP transmission network 45 is combined and sent to the user equipment. The access gateway 44 combines the LTE data transmitted from the TDM network 43 and the IP transmission network 45 and sends it to other nodes on the network side, and selects the TDM transmission network 43 or the IP transmission network 45 to send to the base station 40 according to the attributes of the LTE service data. data.

Between GSM and LTE, a part of transmission resources can be uniformly optimized. The base station controller 41 and the core network 42 and the access gateway 44 can uniformly manage and configure transmission resources. For example, when the TDM transmission time slot of GSM is idle, it can be partially adjusted to LTE for use, that is, IP packets are carried on these time slots. In the network system, when the data of the LTE network is transmitted between the multimode base station 40 and the access gateway 44, the TDM transmission network 43 or the IP transmission network 45 is selected according to the service attribute. For LTE signaling, the TDM transmission network 43 is preferentially selected. For services of the LTE network with high priority and/or high quality of service QoS requirements, the TDM transmission network 43 is preferentially transmitted to transmit data of the service, typically, for example, voice service, flow. Media services, etc.; For other services of the LTE network (eg, services with low priority and/or low QoS requirements), the IP transport network 45 is selected to transmit its service data, such as, Business, etc. In general, for the GSM service data, the TDM transmission network 43 is preferentially transmitted. Of course, for the GSM service with low priority and/or low QoS requirements, it can also be transmitted through the IP network. In this case, TDM over IP can be used. In a manner, the TDM data is carried on the IP transmission network 45, such as a mail service in GSM, a short message service, and the like.

In the network system shown in FIG. 4, although the sub-transmission line between the eNodeB 401 and the access gateway 44 needs to pass through the base station controller 41, the base station controller 41 does not need to parse the information content of the upper layer, and only needs to be controlled at the base station. The device 41 works with the transmission resources of other systems at the physical layer, and performs some multiplexing/demultiplexing, switching, or routing processing operations at the data link layer or the IP layer at most.

In the network system shown in FIG. 4, an example of processing uplink data is shown in FIG. 5A: Step 500: The multimode base station 40 receives data sent by the GSM user equipment and the LTE user equipment to the network side. The multimode base station 40 may simultaneously receive data from different users.

Step 501: The multimode base station 40 determines whether the service data is data of the GSM network, and if yes, proceeds to step 504, otherwise proceeds to step 502.

Step 502: The multimode base station 40 determines that the received data is data of the LTE network, and determines whether it is signaling. If yes, proceed to step 504; otherwise, proceed to step 503.

Step 503: The multimode base station 40 determines that the received data is the service data of the LTE network, analyzes the attributes of the service, and if it is high priority and/or high QoS, proceeds to step 504, otherwise, proceeds to step 506.

Step 504: The multimode base station 40 selects the TDM transmission network 43 to send the received data to the base station controller 41.

Step 505: The base station controller 41 forwards the data to the core network 42 or the access gateway 44 according to the destination address, and proceeds to step 507.

Step 506: The multimode base station 40 selects the IP transmission network 45 to send the service data to the access gateway 44. Step 507: The core network 42 processes the received GSM data; the access gateway 44 performs the combined processing of the data transmitted from the TDM transmission network 43 and the IP transmission network 45, and then forwards the data to the network side.

The judgment analysis of the multi-mode base station 40 in the foregoing process is only a specific example. In a specific implementation, the multi-mode base station 40 may have different strategies for analyzing data, such as distinguishing between signaling and service data. Then, the priority information of the service data and the attribute information such as the QoS are further distinguished, and the processing procedure is the same as the above, and will not be described again.

In the network system shown in Figure 4, an example of processing downlink data is shown in Figure 5B (where the downlink data processing for GSM is omitted):

Step 550: The access gateway 44 receives the data sent by the network side to the LTE user equipment.

Step 551: The access gateway 44 determines whether the service data is signaling, and if yes, proceeds to step 553; otherwise, proceeds to step 552.

Step 552: The access gateway 44 analyzes the attributes of the service data of the LTE network. If it is high priority and/or high QoS, go to step 553. Otherwise, go to step 554.

Step 553: The access gateway 44 selects the TDM transmission network 43 to send data to the multimode base station 40, and proceeds to step 555.

Step 554: The access gateway 44 selects the IP transmission network 45 to send data to the multimode base station 40. Step 555: The multi-mode base station 40 combines the data transmitted from the TDM transmission network 43 and the IP transmission network 45 and sends the data to the corresponding LTE user equipment.

FIG. 6 shows an example of another network structure for adding an LTE access network technology based on a GSM network in this embodiment. The network system in this example includes a multimode base station 60, a base station controller 61 of GSM, and a core network. CN62 and access gateway aGW64. The multimode base station 60 is connected to the base station controller 61 via the TDM transmission network 63 and the IP transmission network 65; the base station controller 61 is connected to the core network 62 and the access gateway 64 via the TDM transmission network 63. The multi-mode base station 60 has a GSM BTS600 and an LTE eNodeB 601. The BTS 600 is responsible for accessing the GSM user equipment, and the eNodeB 601 is responsible for accessing the LTE user equipment. The base station controller 61 includes a split/comb function module 610, and the split/combination function The module 610 has QoS for identifying the signaling plane data and the user plane data, and identifying the user plane data, selecting a transmission network for transmitting the data according to the analysis result of the data, and combining the data. In the network system, the branching and combining processing of data is performed by the multimode base station 60 and the base station controller 61. The base station 60 performs the branch processing on the uplink data according to the access system and/or the service attribute, that is, selects the TDM transmission network 63 or the IP transmission network 65 to forward the uplink data, and performs the combined processing on the downlink data, that is, from the TDM network 63. And LTE data combined with the IP transmission network 65 Then sent to the user device. The base station controller 61 combines the LTE data transmitted from the TDM network 63 and the IP transmission network 65 to the access gateway 64, and selects the TDM transmission network 63 or the IP transmission network 65 to transmit data to the base station 60 according to the attributes of the LTE data. .

The main difference between the network system shown in FIG. 6 and the network system shown in FIG. 4 is that the branching and combining functions are completed by the multimode base station 40 and the access gateway 44 in the system shown in FIG. The shunting and combining functions are performed by the multimode base station 60 and the base station controller 61 in the illustrated system. This networking mode facilitates the interconnection of network devices. The analysis and judgment of the data in Figure 6 and the reasonable and shunt processing are the same as those of the network system shown in Figure 4, and will not be described again.

Fig. 7 shows an example of a network structure in which WiMA access technology is added to the GSM network in this embodiment. The network system includes a multimode base station 70, a GSM base station controller 71, a GSM core network CN72, and a connection service network 74 in the WiMAX system. The multimode base station 70 is connected to the base station controller 71 via the TDM transmission network 73, and to the connection service network 74 via the IP transmission network 75; the base station controller 71 is not connected to the core network 72 and the access gateway 74. The multi-mode base station 70 has a GSM BTS700 and a WiMA access service network. The base station BS701 and the gateway GW702 in the ASN, the BTS700 is responsible for accessing the GSM user equipment, and the access service network is responsible for accessing the WiMAX user equipment.

In the network system shown in Fig. 7, the multi-mode base station 70 and the connection service network 74 perform branching and combining processing of data. The multimode base station 70 performs the split processing on the uplink data according to the access system and/or the service attribute, that is, selects the TDM transmission network 73 or the IP transmission network 75 to forward the uplink data, and performs the combined processing on the downlink data, that is, from the TDM. The data of the WiMAX network transmitted by the network 73 and the IP transmission network 75 is combined and sent to the user equipment of the WiMAX system. The connection service network 74 combines the data of the WiMAX network transmitted from the TDM network 73 and the IP transmission network 75 to the other nodes on the network side, and selects the TDM transmission network 73 or the IP transmission network 75 according to the attributes of the WiMAX service data. The modulo base station 70 transmits data.

When the data of the WiMAX network is transmitted between the multimode base station 70 and the base station controller 71, the TDM transmission network 73 is selected according to the service attribute or the IP transmission network 75 is selected. For signaling of WiMAX networks, TDM transport network 73 is preferred for high priority and/or high quality of service QoS requirements The service of the WiMAX network, the TDM transmission network 73 is preferentially transmitted to transmit data of the service, typically, for example, voice service, streaming service, etc.; other services for the WiMAX network (eg, low priority and/or low QoS requirements) ), the IP transport network 75 is selected to transmit its service data, such as mail service. In general, for the GSM service data, the TDM transmission network 73 is preferentially transmitted. Of course, for the GSM service with low priority and low Z or QoS requirements, it can also be transmitted over the IP network. In this case, TDM over IP can be used. In a manner, the TDM data is carried on the IP transmission network 75, such as a mail service in GSM, a short message service, and the like.

In the network shown in FIG. 7, the processing of the uplink data and the downlink data is the same as that of the network system shown in FIG. 4, and will not be described again.

Fig. 8 shows an example of another network structure in which WiMA access technology is added to the GSM network in this embodiment. The network system includes a multimode base station 80, a GSM base station controller 81, a GSM core network CN82, and a connection service network 84 in the WiMAX system. The multimode base station 80 has a BTS 800 of GSM and a base station BS 801 in the access service network ASN of the WiMAX, and the base station controller 81 has a gateway GW 802 in the access service network ASN. The multimode base station 80 is connected to the base station controller 81 via the TDM transmission network 83, and to the base station controller 81 and the service network 84 via the IP transmission network 85; the base station controller 81 is connected to the core network 82 and the connection service network 84, respectively.

As can be seen from the network system shown in FIG. 8 and FIG. 7, the main difference between the network structure and the network structure shown in FIG. 7 is that in the network system shown in FIG. 7, the base station BS701 and the gateway GW702 are both set in multimode. The base station 70, and in the network system shown in FIG. 8, the base station BS801 is disposed on the multimode base station 80, and the gateway GW802 is disposed on the base station controller 81.

In the network system shown in FIG. 8, the multimode base station 80, the base station controller 81, and the connection service network 84 can all adopt a split transmission mode. For example, the uplink data sent by the WiMA user equipment is selected by the base station 80 to be transmitted by the TDM transmission network 83 or the IP transmission network 85. The data for the WiMA network may be combined in the base station control 81, or may be combined in the connection service network 84. Processing; for the downlink data sent by the WiMA network, the connection service network 84 may select the TDM transmission network 83 or the IP transmission network 85 to transmit, or the connection service network 84 may send the data to the base. The station control 81 is selected by the base station controller 81 for transmission by the TDM transmission network 83 or the IP transmission network 85. When transmitting data of a WiMAX network through a TDM transmission network, TDM over IP can be used.

Although the above description is based on the case where the multimode base station supports GSM access and LTE access, and supports GSM access and WiMAX access, but is not limited thereto, the above described split transmission is also applicable to the multimode base station supporting UMTS connection. Incoming and LTE access, supporting UMTS access and WiMA access, and supporting a combination of three or more of GSM access, UMTS access, LTE access, and WiMA access.

Figure 9 shows an example of a network structure that adds LTE access technology to the UTMS network. The network structure is similar to the networking structure shown in Figure 4. The multi-mode base station 90 includes a NodeB900 with a UTMS and an eNodeB 901 for LTE. The NodeB900 is responsible for accessing the UTMS user equipment, and the eNodeB 401 is responsible for accessing the LTE user equipment. Different from FIG. 4, between the multimode base station 90 and the radio network controller 91, and between the radio network controller 91 and the core network 92 and the access gateway 94 are connected through the ATM transport network 93; through the ATM transport network 93 When transmitting data of the LTE network, the IP Over ATM technology, the signaling of the LTE network, and the service data of the high priority and/or high quality of service QoS are preferentially selected to be transmitted by the ATM transmission network 93, and other service data of the LTE network is adopted. The IP transmission network 95 transmits the same manner as the network system shown in FIG.

FIG. 10 shows an example of a network structure for adding an LTE access technology based on a GSM and UTMS network, in which a multi-module base station and a base station controller (including a BSC and an RNC) are transmitted through an ATM network and TDM transport network connection. Since both the TDM transmission network and the ATM transmission network have high transmission performance, the multimode base station and the base station controller select the transmission network in descending order of QoS performance from the TDM transmission network, the ATM transmission network, and the IP transmission network. Transmit signaling, high priority and high QoS traffic data. Preferably, the data for the UTMS network is mainly transmitted through the ATM transmission network, the data for the GSM network is mainly transmitted through the TDM transmission network, and for the signaling of the LTE network, the ATM transmission network or the TDM transmission network transmission is selected. The branching and combining processing of data in the network system and the processing in the foregoing network system Cheng Tongli, no longer repeat them.

According to FIG. 4 to FIG. 10 and the foregoing description, a person skilled in the art can easily obtain a network structure in which LTE access technology and WiMAX access are added on the basis of GSM and UTMS networks, and data processing and the foregoing in this structure The network system is the same, and will not be described again.

FIG. 11 is a schematic structural diagram of a split/combination function module in the embodiment, which mainly includes a first identification module 110, a selection module 111, a second identification module 112, and a combining module 113. The first identification module 110 identifies different radio access systems (such as the GSM system and the LTE system) according to the received data, identifies signaling plane data and user plane data of a certain radio access system, and identifies the user plane. Information such as priority and QoS of the data; the selection module 111 selects a transmission network that transmits data based on the recognition result. The second identification module 112 identifies different wireless access systems (such as the GSM system and the LTE system) according to data accessed from multiple transmission networks, and identifies signaling plane data and user plane data of a certain wireless access system; The combining module 113 combines the data of a certain system according to the recognition result and sends the data to the user equipment. The shunt/combining function module can be disposed in the foregoing multi-mode base station, as well as an access gateway having a splitting and combining function and a connection service network, or even as a separate entity.

Although the foregoing describes an example in which data is transmitted between a multimode base station and an upper node thereof, the method in this embodiment is also applicable to data transmission between two multimode base stations, because there may be multiple transmissions between two base stations. The internet. The implementation manner is the same as the above, and will not be described again.

In this embodiment, the implementation of the split transmission strategy can be implemented in a variety of ways. For example, according to the signaling plane and user plane classification, let all signaling go "high-performance" transmission path, let the user plane data go to other transmission paths; for example, the signaling plane is established in ATM with GSM TDM transmission network or UMTS The transmission network is "shared" on the transmission path; the user plane is built on the "cheap IP transmission network". For example, according to the quasi-static configuration mode based on the service priority attribute, when the transmission bearer for a certain service is established, the service priority attribute is analyzed to determine which transmission lines the service transmission bearer is established on, for example, HSDPA. The service takes the public network IP transmission; the voice and streaming media take the TDM transmission network. For example, according to the real-time dynamic configuration mode, in the transmission process, the transmission layer resources are dynamically adjusted according to the traffic of the current transmission network, and the existing "high quality" transmission resources are fully utilized. For example: For leased El lines, strive to achieve saturated use, but once new high-priority services are accessed, data services with low latency requirements can be "migrated" in time. The other "cheap" delays are not guaranteed. On the transmission path.

The GSM or WiMAX access technology can be added to expand the data service by using the method described in this embodiment to maintain the original GSM service and UMTS service in the multi-standard access network, and the original transmission resources of GSM and UMTS can be fully utilized. The advantages, for example, the use of TDM transmission resources with low delay, can provide clock reference information and other characteristics of transmission signaling, high latency requirements, and then expand other transmission lines (mainly using cheap public IP transmission) Support the growing number of data services on the market. Therefore, using the aforementioned method, the operator can greatly reduce the cost while ensuring the quality of the service transmission.

It is apparent that those skilled in the art can make various modifications and variations to the invention without departing from the spirit and scope of the invention. Therefore, it is intended that the present invention cover the modifications and variations of the invention as claimed.
