[0002] In the 5G NR network, the 5G base station (gNB) is composed of a centralized unit (CU) and a distributed unit (DU). The process of communication between the terminal equipment (UE) and the gNB may specifically include: the CU allocates available data resource bearer (DRB) resources to the UE, and sends the DRB resource allocation result to the DU; the DU allocates corresponding radio access resources to the DRB resources, such as radio link layer control protocol (RLC) resources, and returns the radio access resource allocation result to the CU; the CU sends the radio access resource allocation result to the UE; the UE uses the radio access resources to communicate with the CU through the DU.

[0003] During the process of UE switching across base stations, it is necessary to send the DRB resources on the source side to the target CU, and the target CU accepts the PDU session resources so that the UE can continue to use the wireless access resources on the source side to communicate with the target CU through the target DU.

[0004] However, in the process of implementing the embodiments of the present invention, the inventors discovered that when the CU is accepting PDU session resources, some DRB resources may fail to be accepted. If the UE uses the wireless access resources corresponding to the DRBs that failed to be accepted to communicate, it will cause UE service interruption. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a resource management method and network equipment, which can reduce the service interruption rate of terminal equipment during cross-base station switching.

[0025] To make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0026] The first embodiment of the present invention relates to a resource management method, the process of which is as follows: Figure 1 As shown, including:

[0027] Step 101: Receive a handover request, wherein the handover request carries information about a first data bearer resource used by a terminal device on a source side during an inter-base station handover.

[0028] Step 102: perform resource acceptance according to the first data bearer resource information, and obtain second data bearer resource information of successfully accepted resources and third data bearer resource information of failed resource acceptance.

[0029] In this implementation, step 102 may include the following three situations:

[0030] Case 1: the successfully accepted data bearer resource information is obtained from the first data bearer resource information as the second data bearer resource information, and the data bearer resource information other than the second data bearer information in the first data bearer resource information is used as the third data bearer resource information.

[0031] Case 2: Allocate new data bearer resources for the terminal device, use the new data bearer resource information as the second data bearer resource information, and use the first bearer resource information as the third data bearer resource information.

[0032] Case three: The data bearer resource information that is successfully accepted is obtained from the first data bearer resource information as the first sub-data bearer resource information, new data bearer resources are allocated to the terminal device, the new data bearer resource information is used as the second sub-data bearer resource information, the first sub-data bearer resource information and the second sub-data bearer information are used as the second data bearer resource information, and the data bearer resource information in the first data bearer resource information excluding the first sub-data bearer information is used as the third data bearer information.

[0033] Of course, the above three situations are only specific examples, and each situation will not be described in detail here.

[0034] Step 103: Send the second data bearer resource information and the third data bearer resource information to the distribution unit.

[0035] In this implementation, step 103 can send the second data bearer resource information and the third data bearer resource information to the distribution unit through a variety of methods.

[0036] For example, Figure 2 As shown, step 103 may include:

[0037] Step 201: Add the second data bearer resource information to the DRB to Be Setup List field in the terminal equipment up and down setup request (UE CONTEXTSETUPREQUEST).

[0038] Step 202: Add the first data bearer resource information to the Handover Preparation Information field in the UE CONTEXT SETUP REQUEST.

[0039] Step 203: Send a UE CONTEXT SETUP REQUEST to the distribution unit.

[0040] For example, Figure 3 As shown, step 103 may include:

[0041] Step 301, adding the second data bearer resource information to the DRBtoBe Setup List field in the UE CONTEXT SETUP REQUEST;

[0042] Step 302: Add a DRB to Be Released List field in the UE CONTEXT SETUP REQUEST, and add the third data bearer resource information to the DRB to Be Released List field.

[0043] Step 303: Send a UE CONTEXT SETUP REQUEST to the distribution unit.

[0044] Of course, the above two methods are only specific examples. In actual use, the second data bearing resource information and the third data bearing resource information may be sent to the distribution unit by other methods, which will not be described in detail here.

[0045] Step 104: Receive radio access bearer resource configuration information returned by the distribution unit according to the second data bearer resource information and the third data bearer resource information.

[0046] Step 105: Send the radio access bearer resource configuration information to the terminal device.

[0047] In this implementation, step 105 may send a switching command reconfiguration (RRCReconfiguration) indication to the terminal device, and add the radio access bearer resource configuration information to the RadioBearerConfig field.

[0048] Compared with the prior art, the embodiments of the present invention can send the second data bearer resource information of successful resource acceptance and the third data bearer resource information of failed resource acceptance to the distribution unit, so that the distribution unit can allocate and manage the corresponding wireless access bearer resources according to the second data bearer resource information and the third data bearer resource information. After receiving the wireless access bearer resource configuration information, the wireless access bearer resource information can be sent to the terminal device, so that the wireless access bearer resources of the terminal device are consistent with the network side, thereby reducing the service interruption rate of the terminal device during the cross-base station switching process.

[0049] The second embodiment of the present invention relates to a resource management method, the process of which is as follows: Figure 4 As shown, including:

[0050] Step 401, receiving the second data bearing resource information and the third data bearing resource information sent by the centralized unit, wherein the second data bearing resource information is the bearer resource information of successful resource acceptance when resource acceptance is performed according to the first data bearing resource information used by the terminal device on the source side during the cross-base station switching process, and the third data bearing resource information is the bearer resource information of failed resource acceptance when resource acceptance is performed according to the first data bearing resource information used by the terminal device on the source side during the cross-base station switching process.

[0051] In this implementation, step 401 may receive the second data bearer resource information and the third data bearer resource information sent by the centralized unit through a variety of methods.

[0052] For example: Figure 5As shown, step 401 may include:

[0053] Step 501, receiving a UE CONTEXT SETUP REQUEST sent by a centralized unit;

[0054] Step 502: Acquire the second data bearer resource information from the DRB to Be Setup List field of the UE CONTEXT SETUP REQUEST.

[0055] Step 503: Acquire the first data bearer resource information from the Handover Preparation Information field of the UE CONTEXT SETUP REQUEST.

[0056] Step 504: Acquire third data bearer resource information according to the first data bearer resource information and the second data bearer resource information.

[0057] Another example: Figure 6 As shown, step 401 may include:

[0058] Step 601: Receive a UE CONTEXT SETUP REQUEST sent by a centralized unit.

[0059] Step 602: Acquire the second data bearer resource information from the DRB to Be Setup List field of the UE CONTEXT SETUP REQUEST.

[0060] Step 603: Acquire the third data bearer resource information from the DRB to Be Released List field of the UE CONTEXT SETUP REQUEST.

[0061] Of course, the above two methods are only specific examples. In actual use, the second data bearer resource information and the third data bearer resource information sent by the centralized unit may also be received through other methods, which will not be described one by one here.

[0062] Step 402: Release the radio access bearer resources corresponding to the third data bearer resource information.

[0063] In this implementation, the radio access bearer resource may specifically be an RLC resource.

[0064] Step 403: Send radio access bearer resource configuration information to the centralized unit, wherein the radio access bearer configuration information is used to instruct to release the radio access bearer resources corresponding to the third data bearer resource information.

[0065] In this implementation, step 403 may add the radio access bearer resource information corresponding to the third data bearer resource information to the CellGroupConfig field of the terminal equipment up / down setup response (UE CONTEXT SETUP RESPONSE), and send the UE CONTEXT SETUP RESPONSE to the centralized unit.

[0066] Compared with the prior art, the embodiments of the present invention can receive the second data bearer resource information of successful resource acceptance and the third data bearer resource information of failed resource acceptance from a centralized unit, release the wireless access bearer resource corresponding to the third data bearer resource information, and notify the centralized unit of the release result (wireless access bearer resource configuration information) so that the centralized unit can send the wireless access bearer resource information to the terminal device, thereby keeping the wireless access bearer resource of the terminal device consistent with the network side, thereby reducing the service interruption rate of the terminal device during the cross-base station switching process.

[0067] The third embodiment of the present invention relates to a resource management method, the process of which is as follows: Figure 7 As shown, including:

[0068] Step 701, receiving the second data bearer resource information and the third data bearer resource information sent by the centralized unit, wherein the second data bearer resource information is the bearer resource information of successful resource acceptance when resource acceptance is performed according to the first data bearer resource information used by the terminal device on the source side during the cross-base station switching process, and the third data bearer resource information is the bearer resource information of failed resource acceptance when resource acceptance is performed according to the first data bearer resource information used by the terminal device on the source side during the cross-base station switching process.

[0069] In this embodiment, the specific implementation method of step 701 can refer to the description of step 401 and will not be repeated here.

[0070] Step 702: Allocate new radio access bearer resources according to the second data bearer resource information.

[0071] Step 703: Release the radio access bearer resources corresponding to the third data bearer resource information.

[0072] Step 704: Send radio access bearer resource configuration information to the centralized unit, wherein the radio access bearer configuration information is used to indicate adding new radio access bearer resources and releasing the radio access bearer resources corresponding to the third data bearer resource information.

[0073] In this embodiment, step 704 can add the new radio access bearer resource information and the radio access bearer resource information corresponding to the third data bearer resource information to the CellGroupConfig field of the terminal device up and down setup response (UE CONTEXT SETUP RESPONSE), and send the UE CONTEXT SETUP RESPONSE to the centralized unit.

[0074] On the basis of achieving the technical effect provided by the second embodiment, the embodiment of the present invention can further allocate new wireless access bearer resources for the second data bearer resource information, and send the new wireless contact bearer resource information to the centralized unit, so that the centralized unit can send the new wireless contact bearer resource information to the terminal device, thereby making the wireless access bearer resources of the terminal device consistent with the network side, thereby reducing the service interruption rate of the terminal device during the cross-base station switching process.

[0075] The technical solutions provided in the first to third embodiments above are applied when the UE switches from the source to the target side across base stations, and the target gNB is composed of a target CU and a target DU.

In order to enable those skilled in the art to more clearly understand the technical solutions provided in the above embodiments, they are specifically described below through different application scenarios.

[0076] Scenario 1: The first data bearer resources used by the UE on the source side include: DRB1 and DRB2. The CU on the target side can only successfully accept DRB1 when accepting resources, and DRB2 acceptance fails, that is: the second data bearer resource is DRB1, and the third data bearer resource is DRB2.

[0077] like Figure 8 As shown, the resource management method provided by the fourth embodiment of the present invention includes:

[0078] In step 801, the source gNB or the Authentication Management Function (AMF) sends a HandoverRequest to the target CU, and carries DRB1 and DRB2 in the Handover Preparation Information of the HandoverRequest.

[0079] Step 802: The target CU determines that DRB1 resource admission is successful, but DRB2 resource admission fails.

[0080] Step 803: The target CU sends a UE CONTEXT SETUP REQUEST to the target DU, adds DRB1 to the DRB to Be Setup List field, and adds the Handover Preparation Information of the HandoverRequest to the Handover Preparation Information in the CU to DU RRC Information.

[0081] Step 804, the target DU obtains DRB1 whose resources are successfully accepted from the DRB to Be Setup List of the UE CONTEXT SETUP REQUEST, obtains DRB1 and DRB2 on the source side from the Handover Preparation Information, determines DRB2 whose resources fail to be accepted, and finds RLC2 corresponding to DRB2.

[0082] Step 805: The target DU sends a UE CONTEXT SETUP RESPONSE to the target CU, and adds RLC2 to the CellGroupConfig.

[0083] Step 806: The target CU sends RRCReconfiguration to the UE, wherein the RRCReconfiguration carries the CellGroupConfig.

[0084] like Fig. 9 As shown, the resource management method provided by the fifth embodiment of the present invention includes:

[0085] Step 901: The source gNB or AMF sends a HandoverRequest to the target CU, and carries DRB1 and DRB2 in the Handover Preparation Information of the HandoverRequest.

[0086] Step 902: The target CU determines that DRB1 resource admission is successful, but DRB2 resource admission fails.

[0087] Step 903: The target CU sends a UE CONTEXT SETUP REQUEST to the target DU, adds DRB1 to the DRB to Be Setup List field, and adds DRB2 to the DRB to Be Released List field.

[0088] Step 904: The target DU obtains DRB1 whose resources are successfully accepted from the DRB to Be Setup List of the UE CONTEXT SETUP REQUEST, obtains DRB2 whose resources are failed to be accepted from the DRB to Be Released List field, and finds RLC2 corresponding to DRB2.

[0089] Step 905: The target DU sends a UE CONTEXT SETUP RESPONSE to the target CU, and adds RLC2 to the CellGroupConfig.

[0090] Step 906: The target CU sends RRCReconfiguration to the UE, wherein the RRCReconfiguration carries the CellGroupConfig.

[0091] Scenario 2: The first data bearer resources used by the UE on the source side include: DRB1 and DRB2. The CU on the target side can only successfully accept the new DRB3 when accepting resources. DRB1 and DRB2 fail to be accepted, that is: the second data bearer resource is DRB3, and the third data bearer resource is DRB1 and DRB2.

[0092] like Fig.10 As shown, the resource management method provided by the sixth embodiment of the present invention includes:

[0093] Step 1001: The source gNB or AMF sends a HandoverRequest to the target CU, and carries DRB1 and DRB2 in the Handover Preparation Information of the HandoverRequest.

[0094] Step 1002, the target CU determines that the newly added DRB3 resources are accepted successfully, and the DRB1 and DRB2 resources fail to be accepted.

[0095] Step 1003: The target CU sends a UE CONTEXT SETUP REQUEST to the target DU, adds DRB3 to the DRB to Be Setup List field, and adds DRB1 and DRB2 to the DRB to Be Released List field.

[0096] Step 1004, the target DU obtains DRB3 whose resources are successfully accepted from the DRB to Be Setup List of the UE CONTEXT SETUP REQUEST, obtains DRB1 and DRB2 whose resources fail to be accepted from the DRB to Be Released List field, finds RLC1 corresponding to DRB1 and RLC2 corresponding to DRB2, and allocates RLC3 to DRB3.

[0097] Step 1005: The target DU sends a UE CONTEXT SETUP RESPONSE to the target CU, and adds RLC1, RLC2, and RLC3 to the CellGroupConfig.

[0098] Step 1006: The target CU sends RRCReconfiguration to the UE, wherein the RRCReconfiguration carries CellGroupConfig.

[0099] Compared with the prior art, the embodiment of the present invention sends the second data bearer resource information of successful resource acceptance and the third data bearer resource information of failed resource acceptance to the target DU, so that the target DU can allocate and manage the corresponding RLC according to the second data bearer resource information and the third data bearer resource information. After receiving the radio access bearer resource configuration information sent by the target DU, the target CU can send the radio access bearer resource information to the UE, so that the radio access bearer resources of the UE are consistent with the target CU and the target DU, thereby reducing the service interruption rate of the terminal device during the cross-base station switching process. Furthermore, the communication process of the embodiment of the present invention adopts the existing process and messages, without adding new processes or messages, saving communication costs.

The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, providing a unit for communicating with various other devices on a transmission medium. The data processed by the processor is transmitted on a wireless medium via an antenna, and further, the antenna also receives data and transmits the data to the processor.

[0105] The processor is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interfaces, voltage regulation, power management, and other control functions. Memory can be used to store data used by the processor when performing operations.
