Description

Method for feedback information and wireless network control node

The present invention relates to the field of communications, and in particular to a method for feedback information and a wireless network control node in the field of communications. Background technique

The Self Organizing Network ("SON") technology is a self-optimizing technology of the network, in which the network determines the optimization and adjustment of network parameters by collecting user information. A typical application of SON technology is mobile robustness self-optimization, that is, user equipment (User Equipment, called "UE") records information about radio link failure or handover failure occurring in the network, when the UE again and When the network establishes a connection, the UE reports the above-mentioned failure information to the network. After the network statistics and analyzes the failure information of a large number of UEs, the reason for the failure problem can be inferred, so that the mobility-related parameters can be further adjusted. The network automatically adjusts the mobility parameters to avoid the same failure events in the network.

Currently, through the mobile robustness self-optimization technology, the network can identify and optimize problem scenarios such as premature handover, late handover, handover to the wrong cell, and ping-pong handover.

Different system ping-pong switching refers to the process in which the UE switches from the source system to the target system and from the target system back to the source system in a short time, wherein the source system and the target system have different wireless access systems.

The UE migrates from the target system back to the source system, either through the switching mode or through the redirection method. For the heterogeneous system ping-pong handover, the current mobile robustness self-optimization technique only considers the case where the UE returns to the source system from the target system through the handover mode, and does not consider the case where the UE returns to the source system through the redirection manner, so that the system cannot be fully statistically calculated. The reason for the ping-pong switching is analyzed, so that the same ping-pong switching will inevitably occur in the network. Summary of the invention

As shown in FIG. 1, the method 100 includes:

S110. Receive measurement configuration information sent by the first radio network control node, where the measurement configuration information is used to indicate that the user equipment performs signal quality measurement on the cell of the first radio access system for a predetermined measurement duration, where the user equipment The first wireless network control node is switched to the second wireless network control node, where the first wireless network control node is an access network control node of the first wireless access system, and the second wireless network control node is An access network control node of the second radio access system; S120, instructing the user equipment to perform the signal quality measurement according to the measurement configuration information; S130, receiving at least one measurement result of the user equipment to perform the signal quality measurement; S140 Before the end of the predetermined measurement duration, when the user equipment migrates to the network of the first radio access system in a redirected manner, and each of the at least one measurement result includes at least one signal quality greater than When the cell of the first radio access system of the threshold value is sent to the control node of the first radio network Handover report, the handover report information for indicating premature switching.

That is, in the embodiment of the present invention, after the user equipment has successfully switched from the first wireless network control node to the second wireless network control node, the second wireless network control node may receive the first wireless network control node. The measured configuration information is sent; thus, the second wireless network control node can be rooted Determining, by the measurement configuration information, the user equipment to perform signal quality measurement on the cell of the first radio access system for a predetermined measurement duration, and receiving at least one measurement result of the signal quality measurement by the user equipment; Before the end of the measurement duration, the user equipment migrates to the network of the first wireless access system in a redirected manner, and the second wireless network control node receives the user equipment for the first wireless access system each time. When the result of the signal quality measurement by the cell indicates that at least one cell of the first radio access system whose signal quality is greater than the threshold, the second radio network control node may send the control node to the first radio network. Switch the report to indicate premature switching information.

Therefore, the method for feeding back information in the embodiment of the present invention sends a handover report to the control node of the access network of the first radio access system when the UE migrates to the network of the first radio access system in a redirection manner. The access network control node can comprehensively count and analyze the reason of the handover, thereby optimizing the handover parameters and avoiding the same failure event in the network, thereby improving system performance and enhancing the user experience.

Specifically, in S110, the second radio network control node receives measurement configuration information sent by the first radio network control node, where the measurement configuration information is used to indicate that the user equipment accesses the first radio access within a predetermined measurement duration. The cell of the system performs signal quality measurement, and the user equipment successfully switches from the first radio network control node to the second radio network control node.

The measurement configuration information may include a predetermined measurement duration, for example, the predetermined measurement duration may be set to Is to 100s; and, for example, the measurement configuration information may further include a measurement frequency point and a threshold value. For example, for an LTE system, the measurement frequency point may be an E-UTRAN Absolute Radio Frequency Channel Number (E-UTRAN Absolute Radio Frequency Channel Number, which is called "E-ARFCN", where the universal terrestrial land The Evolved Universal Terrestrial Radio Access Network is called "E-UTRAN" to identify a downstream frequency. In the embodiment of the present invention, the threshold value may be a reference signal received power (Reference Signal Received Power, referred to as "RSRP") threshold, or may be a reference signal received quality (Reference Signal Received Quality, The "RSRQ" threshold value may also be other threshold values for evaluating the signal quality of the cell, and the present invention is not limited thereto.

It should be further understood that the measurement configuration information may further include information such as a measurement result reporting time or a reporting period, so that the user equipment may report the signal quality measurement result multiple times or periodically report the signal quality measurement result, but the embodiment of the present invention does not Limited to this.

In the embodiment of the present invention, the second wireless network control node may be based on receiving the indication for cutting Determining the success of the message or message, determining that the user equipment successfully switches from the first wireless network control node to the second wireless network control node; the second wireless network control node may also determine the user equipment based on, for example, receiving the measurement configuration information. The first wireless network control node successfully switches to the second wireless network control node, but the invention is not limited thereto.

For example, when the second wireless network control node receives the handover complete message sent by the user equipment, the second wireless network control node may determine that the user equipment successfully switches from the first wireless network control node to the second wireless network control node. .

In the embodiment of the present invention, the radio access system may include a GSM system, a WCDMA system, an LTE system, and a Wi-Fi system, and the corresponding radio network control node may include a BSC, an RNC, an eN B, and an access node (Access Point, The cartridge is called "AP"). It should be understood that, in the embodiment of the present invention, the radio access system may further include other systems, and the corresponding radio network control node may also include other control nodes, and the present invention is not limited thereto.

In S120, the second wireless network control node instructs the user equipment to perform the signal quality measurement according to the measurement configuration information.

In the embodiment of the present invention, the second radio network control node instructs the user equipment to perform signal quality measurement on the cell of the first radio access system for a predetermined measurement duration, for example, according to the predetermined measurement duration included in the measurement configuration information; Or the second wireless network control node may indicate the user equipment to perform signal quality measurement according to the information such as the predetermined measurement duration, the measurement frequency, and the threshold value included in the measurement configuration information, and the embodiment of the present invention is not limited thereto. For example, the second radio network control node instructs the user equipment to perform the signal quality measurement according to the reporting time or the reporting period included in the measurement configuration information, and controls the signal quality measurement result on the node to the second wireless network.

In S130, the second radio network control node receives at least one measurement result of the signal quality measurement performed by the user equipment on the cell of the first radio access system.

It should be understood that, after receiving the measurement configuration information, the second radio network control node may send the measurement control information to the user equipment according to the measurement configuration information, and is used to indicate that the user equipment performs signal quality on the cell of the first radio access system. The user equipment performs cell measurement according to the measurement control information, and periodically reports the measurement result to the second wireless network control node. For example, the measurement result may include measuring a cell identifier of the cell, a measurement result of the cell, and the like, and the measurement result is, for example, an RSRP measurement result and/or an RSRQ measurement result, etc., and the measurement result may also include other information, and the present invention does not Limited to this.

It should also be understood that the user equipment can control the junction to the second wireless network multiple times according to the measurement configuration information. A measurement result is reported, and a measurement result is reported each time. The measurement result may include, for example, an identifier of a cell of a first radio access system whose signal quality is greater than a threshold, but the embodiment of the present invention is not limited thereto.

In S140, before the end of the predetermined measurement duration, when the second wireless network control node determines that the user equipment migrates to the network of the first wireless access system in a redirected manner, and the second wireless network control node And when each of the received at least one measurement result includes at least one cell of the first radio access system whose signal quality is greater than a threshold, the second radio network control node controls the node to the first radio network The point sends a switch notification, which is used to indicate premature handover information.

It should be understood that the second wireless network control node may determine to migrate the user equipment to the network of the first wireless access system in a redirected manner according to information about the capabilities of the user equipment, the service priority of the user equipment, or the service rate. For example, when the UE does not have the capability of different system switching, but has the same system switching capability, the network can only migrate the UE to another network in the same system in a redirected manner; or can be used for a UE with a high service priority. The mode of the handover is performed to reduce the delay of the UE service interruption. For the UE with the lower service priority, the UE can be redirected.

Before the end of the predetermined measurement duration indicated by the measurement configuration information, when the second wireless network control node determines that the user equipment migrates to the network of the first wireless access system in a redirected manner, the second wireless network control node evaluates the user The device performs a measurement result of the signal quality measurement on the cell of the first radio access system.

It should be understood that the second wireless network control node evaluates the measurement result without requiring the user equipment to migrate as long as the second wireless network control node determines that the user equipment migrates to the network of the first wireless access system in a redirected manner. Return to the same first radio access system cell or the same first radio network control node. That is, when the user equipment returns to the network of the first radio access system again, the cell in which the user equipment is located may be the same as or different from the previous cell; and the radio network control node serving the user equipment may be the same, or Different, but the invention is not limited thereto.

If the measurement result of the at least one cell of the first radio access system is greater than a threshold value, the second radio network control node receives the at least one of the second radio network control nodes. When each measurement result of a measurement result includes at least one cell of the first radio access system whose signal quality is greater than a threshold value, the second radio network control node may send the control node to the first radio network control node. Switch 4 notifications to indicate premature switching information; If the measurement result received by the second radio network control node does not include at least one cell of the first radio access system whose signal quality is greater than the threshold, the second radio network control node may not The first wireless network control node feeds back the premature switching information.

In the embodiment of the present invention, optionally, the handover report further carries the handover information used to indicate the premature handover. Optionally, the handover report further includes redirection information, where the redirection information is used to indicate the handover. The trigger for the obituary is the redirect trigger. That is, the handover report sent by the second radio network control node to the first radio network control node may also be used to notify the first radio network control node that the handover report is triggered by the redirection.

It should be understood that, in the embodiment of the present invention, the handover may further include a cell identifier that exceeds a threshold in the measurement result on the user equipment, to indicate that the network of the first radio access system is inappropriate for the handover. The next time you can consider switching to another cell, you can avoid the same failure event in the network.

In the embodiment of the present invention, the first radio access system and the second radio access system may be the same. For example, the first radio access system and the second radio access system are both LTE standards, that is, the user equipment is in the LTE system. Switching from one cell to another cell; optionally, the first radio access system is different from the second radio access system, for example, the first radio access system is an LTE system, and the second radio access system is UMTS format.

When the first radio access system is different from the second radio access system, the migration of the user equipment may also be referred to as a different system handover. For example, as shown in FIG. 2, the user equipment migrates from the network of the first wireless access system (LTE network) to the network of the second wireless access system (UMTS network), and then from the network of the second wireless access system ( UMTS network) Migrate back to the first wireless access standard network (LTE network). It should be understood that the embodiment of the present invention is described by taking only the different system switching as an example, but the present invention is not limited thereto, and the method for feeding back information according to the embodiment of the present invention can also be applied to the switching in the network system of the same standard.

It should also be understood that in the embodiments of the present invention, the term "wireless access system network" or "wireless access system cell" refers to a network or cell having a specific wireless access system, for example, "first wireless "Access to the standard network" means that the network system has the first wireless access system.

It should also be understood that, in the embodiment of the present invention, the so-called "redirect" mode refers to that the radio network control node sends a frequency point to the user equipment, and the user equipment searches for a suitable cell at the specified frequency point, and re-initiates. The establishment of business. The migration mode of the redirection has a relatively small impact on the network. For the handover mode, the source radio network control node and the target radio network control node are required to prepare resources in advance, and the user equipment accesses the source radio network control node. After the specified cell, the service can be directly transmitted.

In the embodiment of the present invention, the UE is migrated from the network of the second radio access system to the network of the first radio access system, and can be implemented by using a handover mode or a redirection manner. If the UE does not end the service in the second radio network control node, the second radio network control node may migrate the UE to the first radio access system network by means of handover or redirection; After the service in the second radio network control node has ended, the second radio network control node may migrate the UE to the network of the first radio access system by using a redirection manner.

For the case where the UE does not end the service in the second radio network control node, if the second radio network control node migrates the UE to the network of the first radio access system by means of redirection, the event is triggered. The reason is consistent with the triggering reason for the handover of the UE to the network of the first radio access system, for example, all of which need to be returned to the network of the first radio access system due to channel quality reasons or cell load reasons. Therefore, in this case, the UE being redirected back to the first radio access system by the second radio network control node also belongs to a ping-pong handover event, and a handover report needs to be sent.

However, in the case that the UE has terminated the service in the second radio network control node, it can be regarded as a normal network operation behavior, and the handover report may not be sent to the first radio network control node.

Therefore, in the embodiment of the present invention, optionally, as shown in FIG. 3, before sending the handover report to the first wireless network control node, the method further includes:

S150. Determine to use when relocating to the network of the first radio access system in a redirected manner. The business of the equipment continues.

Specifically, if the predetermined measurement duration included in the measurement configuration information ends, the user equipment migrates to the network of the first wireless access system in a redirected manner; the second wireless network control node receives each time The measurement result includes at least one cell of the first radio access system whose signal quality is greater than a threshold value; and the second radio network control node determines that the user equipment is migrating to the first radio access in a redirected manner When the service of the user equipment does not end, the second wireless network control node may send a handover report to the first wireless network control node to indicate premature handover information.

In the embodiment of the present invention, the second radio network control node determines that the service end of the user equipment may include the following two situations: In the first case, the second radio network control node detects that the UE inactivity timer expires. The inactivity timer of the UE is used by the second radio network control node to monitor the activity of the UE. When the UE has no data transmission activity within a certain time, the second radio network control node starts the inactivity timer of the UE, if the UE Before the timer expires, the UE still has no data transmission activity, and the second radio network control node may consider that the UE's service has ended. In the second case, the second radio network control node, for example, the RNC, receives the core node from the second radio access system, for example, a Serving GPRS Support Node ("SGSN") The resource release message of " ), then the second radio network control node can consider that the UE's service has ended.

Therefore, in the embodiment of the present invention, optionally, the determining, when the network is migrated to the network of the first radio access system in a redirection manner, the service of the user equipment continues, including:

When the user equipment migrates to the network of the first radio access system in a redirected manner, if the resource release message sent by the core network node of the second radio network control node is not received, and/or the user If the inactivity timer of the device does not time out, it is determined that the service of the user equipment continues.

The following is a detailed description of a method for feeding back information according to an embodiment of the present invention, in which a user equipment is switched between an LTE system and a UMTS system, with reference to FIG. 4, where the first wireless access system The network is an LTE network, and the network of the second radio access system is a UMTS network, the first radio network control node is eNB1, and the second radio network control node is an RNC.

In S310, the eNB1 initiates a handover procedure to the RNC. Specifically, the eNB1 may send the measurement configuration information to the RNC in the handover request message sent to the RNC, where the measurement configuration information may include, for example, the measured frequency point, the threshold value, and the duration measured by the UE. The measurement configuration information can also report relevant information, for example, by measuring the result. Therefore, the RNC can determine that the user equipment successfully switches from the first radio network control node eNB1 to the second radio network control node RNC; and receives the measurement configuration information sent by the first radio network control node eNB1.

In S320, the RNC sends measurement control information to the UE according to the measurement configuration information, where the measurement control information is used to indicate that the UE performs signal quality measurement on the cell of the first radio access system, and the measurement control information may also include, for example, the measured frequency. Point, threshold, duration of UE measurement, reporting period, etc.

In S330, the UE may periodically report the measurement result to the RNC, and the measurement result may include the identifier of the measured cell and the signal quality measurement result of the cell.

In S340, before the end of the predetermined measurement duration indicated by the measurement configuration information, the RNC determines to migrate the UE to the third wireless network control node eNBx of the network of the first wireless access system in a redirected manner, the third wireless The network control node is an access network control node of the first radio access system, and the third radio network control node may be the same as the first radio network control node, or may be different, that is, the eNBx may be the eNB1. It can also be other eNBs.

In S350, before the end of the predetermined measurement duration, when the UE migrates to the LTE network in a redirected manner, the RNC needs to evaluate the received measurement result, and determine whether the RNC receives the measurement result each time. Both indicate that the signal quality of at least one cell of the first radio access system is greater than a threshold.
