[0002] In 5G voice services, during the process of voice services falling back from the 5G network to the 4G network (evolved packet system fallback, EPS Fallback), there may be scenarios where the Quality of Service Flow (QOSFlow) establishment process and the 5G New Radio (NR) handover process occur concurrently, leading to conflicts between the two processes.

[0003] To resolve the conflict between the QoS Flow establishment process and the NR handover process, in the existing technology, when the base station receives a QoS Flow establishment request and is preparing to enable the EPS Fallback process to carry voice, if an NR-side handover request occurs, the base station will prioritize the NR handover, which will cause the base station's QoS Flow establishment to fail, directly leading to the failure of the EPS Fallback process and the failure of the user's voice call. Summary of the Invention

[0032] Figure 3 This is a schematic diagram of the structure of an electronic device provided in one embodiment of this application. Detailed Implementation

[0033] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0035] As described in the background section, in actual voice services, there may be scenarios where the 5QI=1 QoS flow establishment process and the NR handover process occur concurrently during the EPS Fallback process, with the two processes executing independently. Specifically, after the 5G source base station on the radio side triggers the NR handover process and sends a Radio Resource Control (RRC) connection reconfiguration message for handover, it simultaneously receives a PDU session resource request from the Access and Mobility Management Function (AMF) to establish a 5QI=1 session before receiving the RRC connection reconfiguration completion message, causing a conflict between the two processes.

[0036] In existing technology, when the source base station on the wireless side receives a QoS Flow establishment request with 5QI=1 and is preparing to initiate the EPS Fallback process to carry voice, a NR-side handover request occurs. The source base station prioritizes NR handover, causing the source base station's QoS Flow establishment to fail, directly leading to the failure of the EPS Fallback process and the user's voice call not being connected. Furthermore, even if the timer has not expired after the NR handover is completed, continuing the EPS Fallback establishment process will increase the call latency by 2 seconds or more, affecting the user's perception and connection latency.

[0037] To address the aforementioned issues, embodiments of this application provide a request processing method, apparatus, device, and computer storage medium. This request processing method, upon receiving a Protocol Data Unit (PDU) session resource modification request from an Access and Mobility Management Function (AMF) after a first base station sends a handover request message to a target base station, acquires a measurement report sent by a user equipment (UE). If the Reference Signal Received Power (RSRP) and Signal-to-Interference-plus-Noise Ratio (SINR) in the measurement report meet preset thresholds, the method cancels the state transition message in the handover request message sent to the target base station and sends a PDU session resource modification response message to the AMF. This ensures the success of user voice calls and improves user experience when two conflicting requests occur, such as sending a handover request message to the target base station and receiving a PDU session resource modification request. Under conditions of good serving cell coverage, the PDU session resource modification response message is prioritized for sending to the AMF, thereby guaranteeing the success of user voice calls.

[0038] The request processing method provided in the embodiments of this application will be described below.

[0039] Figure 1 A flowchart illustrating a request processing method provided in one embodiment of this application is shown.

[0040] like Figure 1 As shown, the request processing method may specifically include the following steps:

[0041] S110, when the first base station sends a handover request message to the target base station and receives a Protocol Data Unit (PDU) session resource modification request sent by the Access and Mobility Management Function (AMF), the measurement report sent by the user equipment is obtained. The measurement report includes the Reference Signal Received Power (RSRP) and the Signal-to-Interference-plus-Noise Ratio (SINR).

[0042] The first base station can be a 5G base station on the radio side, or a source base station that sends a handover request message to the target base station. The handover request message can be a 5G New Radio (NR) handover request message. During the handover process triggered within the NR system, the first base station receives a Protocol Data Unit (PDU) session resource modification request sent by the AMF, which is a QoS Flow establishment request for voice service (5QI=1). Then, it obtains and analyzes the measurement report sent by the user equipment. The measurement report may include Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR). The user equipment (UE) can be an electronic device such as a mobile phone or computer.

[0043] As an example, during a handover process triggered within the NR system, the 5G source base station receives a QoS Flow establishment procedure for a voice service (5QI=1). This QoS Flow establishment procedure can be as follows: after the source base station sends a handover request message XN_HO_REQ to the target base station, it receives a PDU session resource modification request request message NGAP_PDU_SESSION_RSRC_MODIFY_REQ from the AMF, requesting the establishment of a QoS Flow for the voice service (5QI=1). Next, the source base station obtains the measurement report sent by the user equipment, analyzes the RSRP and SINR in the measurement report, and determines the priority of the handover procedure and the QoS Flow establishment procedure within the NR system.

[0044] S120, when RSRP and SINR meet the preset thresholds respectively, cancel the state transition message in the handover request message sent to the target base station, and send a PDU session resource modification response message to the AMF.

[0045] The preset threshold can be any threshold set by the user according to actual needs. It can be used to determine whether the RSRP and SINR of the current serving cell are good. For example, the RSRP threshold can be set to m and the SINR threshold to n when the current serving cell has good coverage. The values ​​of m and n can be dynamically adjusted according to the actual values ​​of different scenarios. If the RSRP of the Synchronization Signal and PBCH block (SSB) is greater than or equal to m and the SINR of the SSB is greater than or equal to n, it is determined that the RSRP and SINR of the current serving cell meet the good coverage conditions. Then, the first base station cancels the state transition message Xn SN STATUSTRANSFER in the handover request message sent to the target base station, that is, cancels the NR handover process and sends a PDU session resource modification response message to the AMF.

[0046] As an example, measurement report data sent by the UE is acquired, and the RSRP and SINR of the serving cell in the measurement report data are analyzed to determine the priority of the handover procedure and QoS Flow establishment procedure within the NR system. If the RSRP threshold for good serving cell coverage is set to m and the SINR to n, and if SSB RSRP ≥ m and SSB SINR ≥ n, then the good coverage condition is met. Based on the determination of the serving cell's RSRP and SINR, when the source base station triggers an Xn handover request, if the RSRP and SINR received by the UE meet the good coverage condition, the EPS Fallback procedure protection switch is activated. In the EPS Fallback procedure, the NR handover is rejected, the ongoing Xn handover process is canceled, and a PDU session resource modification response message is sent to the AMF, i.e., the QoS Flow establishment procedure is executed first.

[0047] In addition, after entering the process of establishing a voice service QoS Flow (5QI=1), if it is a 5G network end-to-end voice service (VoNR), the establishment process is completed normally; if it is an EPS Fallback call service, the PDU session resource modification response message carries the PDU SessionResource Modify Unsuccessful Transfer information element, with the reason value ims-vioce-eps-fallback-or-rat-fallback-triggered, and triggers the EPS Fallback process.

[0048] In this embodiment, when the first base station sends a handover request message to the target base station and receives a Protocol Data Unit (PDU) session resource modification request from the Access and Mobility Management Function (AMF), it obtains a measurement report sent by the user equipment. If the Reference Received Power (RSRP) and Signal-to-Interference-plus-Noise Ratio (SINR) in the measurement report meet preset thresholds, the state transition message in the handover request message to the target base station is cancelled, and a PDU session resource modification response message is sent to the AMF. This effectively resolves the conflict between the QoS Flow establishment process and the NR handover process. When the serving cell coverage is good, the establishment of the base station's QoS Flow is prioritized, thereby ensuring the success of user voice calls.

[0049] In some embodiments, the request processing method may further include:

[0050] The timer starts when RSRP and SINR meet the preset thresholds.

[0051] When the timeout exceeds the preset duration, a state transition message is sent to the target base station.

[0052] Based on the determination results of RSRP and SINR of the serving cell, when the source base station triggers an NR handover request, if RSRP and SINR meet the preset thresholds respectively, the EPS Fallback process protection switch is activated. In the EPS Fallback process, the NR handover request is rejected, the ongoing Xn handover process is canceled, and the protection switch timer is started. When the timer exceeds the preset duration, a state transition message is sent to the target base station. The preset duration can be arbitrarily set by the user according to actual needs, or it can be set according to the specific network conditions, for example, it can be 1000 to 2000 milliseconds.

[0053] As an example, the RSRP and SINR of the serving cell in the measurement report data are analyzed to determine the priority of the handover procedure and QoS Flow establishment procedure within the NR system. The RSRP threshold for good serving cell coverage is set to m, and the SINR to n. If the RSRP and SINR received by the UE meet the good coverage thresholds, the EPS Fallback procedure protection switch is activated, and the protection switch timer Tx is started simultaneously. In the EPS Fallback procedure, NR handover is rejected, and the ongoing Xn handover process is canceled. When the timer exceeds a preset duration, a state transition message is sent to the target base station, and the NR handover procedure is resumed.

[0054] In this embodiment, by starting a timer when RSRP and SINR respectively meet preset thresholds, the establishment of the EPS Fallback process can be guaranteed within the preset timer duration, thereby ensuring the success of user voice calls, reducing connection latency, and improving user experience. When the timer exceeds the preset duration, a state transition message is sent to the target base station, ensuring the continuation of the NR handover process even after the preset timer duration has elapsed.

[0055] In some embodiments, the preset threshold may include a first preset threshold and a second preset threshold; the request processing method may further include:

[0056] When RSRP does not meet the first preset threshold and / or SINR does not meet the second preset threshold, a state transition message in the handover request message is sent to the target base station.

[0057] The first and second preset thresholds can be arbitrarily set by the user according to actual needs. If RSRP does not meet the first preset threshold and / or SINR does not meet the second preset threshold, the source base station sends a state transition message in the handover request message to the target base station to complete the NR handover process first.

[0058] As an example, when determining the priority of the handover process and QoS Flow establishment process within the NR system, the RSRP threshold for good coverage is set to m, and SINR is set to n. If the RSRP received by the UE does not meet the good coverage threshold, and / or the SINR does not meet the good coverage threshold, the source sends a state transition message in the handover request message to the target base station, that is, the ongoing NR handover process continues.

[0059] In this embodiment of the application, by sending a state transition message in the handover request message to the target base station when RSRP does not meet the first preset threshold and / or SINR does not meet the second preset threshold, the NR handover process of the base station can be prioritized even when the service cell coverage is poor.

[0060] In some embodiments, the request processing method may further include:

[0061] When the timeout period has not exceeded the preset duration and the PDU session resource modification is completed, a state transition message in the handover request message is sent to the target base station.

[0062] If the timer does not exceed the preset duration and the PDU session resource modification is completed, i.e. the EPS Fallback process ends, the EPS Fallback process protection switch is triggered to terminate, the NR handover forwarding function is restored, the state transition message in the handover request message is sent to the target base station, and the original NR handover process continues.

[0063] In this embodiment of the application, by sending a state transition message in the handover request message to the target base station when the timeout has not exceeded the preset duration and the PDU session resource modification is completed, the NR handover process of the base station can be guaranteed to continue after the PDU session resource modification is completed, that is, when the EPSFallback process ends.

[0064] Figure 2 This is a schematic diagram of the structure of a request processing apparatus 200 according to an exemplary embodiment.

[0065] like Figure 2 As shown, the request processing device 200 may include:

[0066] The acquisition module 201 is used to acquire a measurement report sent by the user equipment when the first base station sends a handover request message to the target base station and receives a Protocol Data Unit (PDU) session resource modification request sent by the Access and Mobility Management Function (AMF). The measurement report includes the Reference Received Power (RSRP) and the Signal-to-Interference-plus-Noise Ratio (SINR).

[0067] Cancellation module 202 is used to cancel the state transition message in the handover request message sent to the target base station and send a PDU session resource modification response message to the AMF when RSRP and SINR respectively meet the preset thresholds.

[0068] In one embodiment, the request processing device 200 may further include an initiation module and a sending module;

[0069] The startup module is used to start the timer when RSRP and SINR meet preset thresholds respectively;

[0070] The sending module is used to send a state transition message to the target base station when the timer exceeds a preset duration.

[0071] In one implementation, the preset threshold includes a first preset threshold and a second preset threshold;

[0072] The sending module is also used to send a state transition message in the handover request message to the target base station when RSRP does not meet the first preset threshold and / or SINR does not meet the second preset threshold.

[0073] In one implementation, the sending module is further configured to send a state transition message in the handover request message to the target base station when the timeout has not exceeded a preset duration and the PDU session resource modification is completed.

[0074] Therefore, when the first base station sends a handover request message to the target base station and receives a Protocol Data Unit (PDU) session resource modification request from the Access and Mobility Management Function (AMF), it obtains a measurement report sent by the user equipment. If the Reference Received Power (RSRP) and Signal-to-Interference-plus-Noise Ratio (SINR) in the measurement report meet preset thresholds, the state transition message in the handover request message sent to the target base station is cancelled, and a PDU session resource modification response message is sent to the AMF. This way, even when a handover request message is triggered and a PDU session resource modification request is received, causing a conflict, and the serving cell coverage is good, the PDU session resource modification response message is prioritized for sending to the AMF, thus ensuring the success of user voice calls and improving user experience.
