[0002] At present, since both video calls and video ringback tone services will trigger the establishment of 5QI2 bearers, the way to trigger the switching of video call services through the 5QI2 bearer establishment process cannot be distinguished from the video ringback tone service. Based on the current mechanism, the switching function based on the video call service will mistakenly identify the user who has activated the video ringback tone service voice call as a video call user, and then mistakenly migrate the voice user from 700M to 2.6G (in fact, it is recommended that voice users stay in the 700M band and video users stay in the 2.6G band), which makes the service residence and migration logic chaotic, the network utilization rate is unbalanced, and users cannot stay in the most suitable network band, which ultimately makes the original "speech and digital stratification" and "speech and video stratification" strategies invalid.

[0045] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0046] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of the present application is: when receiving a signaling message for establishing 5QI2, determine whether the signaling message includes the establishment requirement information of 5QI2; if the signaling message includes the establishment requirement information of 5QI2, send the measurement configuration information of the target frequency cell to the user terminal corresponding to the signaling message, wherein the user terminal uploads the measurement report of each target frequency cell based on the measurement configuration information; based on the measurement report, determine the target neighboring cell in each target frequency cell, and execute the switching operation of the user terminal to the target neighboring cell.

[0049] Currently, in 5G wireless networks, different types of services are distinguished by 5QI. Figure 1 As shown in the figure, data services use 5QI9 bearers, and IMS signaling uses 5QI5 bearers, both of which are default bearers established after registration; voice call services use 5QI1 bearers, and video call services use 5QI2 bearers, both of which are dedicated bearers established on demand. When a user only uses data services, the user and the base station only establish 5QI9 and 5QI5 bearers. When the user makes a voice call, a new 5QI1 bearer needs to be created. When the user makes a video call, a new 5QI1 bearer and a 5QI2 bearer need to be created.

[0050] Because it involves high-definition video service transmission, especially 5G new calls also have the need for large packet transmission such as file sharing, the capacity requirement is relatively large. Taking China Mobile as an example, since the bandwidth of the 700MHz frequency band cell is relatively small, the optimization strategy needs to migrate video call users carried in the 700MHz cell to the 2.6GHz cell to avoid possible capacity risks. The implementation of this type of service migration requires the use of "service-based switching" technical means, which can migrate users to the specified target frequency band after identifying a specific service trigger.

[0051] Currently, 5G base stations can trigger video call service switching through 5QI2 bearer establishment, such as Figure 2 As shown, Figure 2The present invention is a flow chart of wireless signaling during the switching process of the video call service; specifically, the source base station gNodeB receives the message established by 5QI2, triggering the switching measurement based on the video call service, and the gNodeB sends a measurement control message of the target frequency to the user terminal UE; the UE performs measurement operations on the surrounding cells corresponding to the target frequency according to the measurement control message, and reports the measurement reports of all cells in the surrounding cells that meet the measurement configuration requirements to the serving cell (the cell to which the current user terminal in the gNodeB belongs); the gNodeB selects the neighboring cell with the strongest RSRP (Reference Signal Receiving Power) as the target frequency cell according to the measurement report, and triggers a switching request to the target base station where the target frequency cell is located; the target base station replies with a switching confirmation message to the gNodeB; the serving cell sends a reconfiguration message to enable the UE to initiate a switching to the target frequency cell; the UE completes access to the target frequency cell, and replies with a reconfiguration completion message to the target frequency cell.

[0052] However, in addition to the video call service, the video ringback tone service will also establish a 5QI2 bearer during the establishment of the calling call. Since the information carried in the INVITE messages of the voice service and the video call service is different, the Accept-Contact header field in the INVITE message of the video call carries an additional "video" identifier, and the m field in the message body also provides a media description of the video service. Therefore, the IMS network can accurately know whether the user is a video or voice call, but the wireless side cannot determine whether the user is a video call user because the SIP message content is not parsed by the wireless base station. Therefore, the current 5G base stations of various manufacturers trigger the switching of video call services through the establishment of a 5QI2 bearer, and cannot distinguish between video call and video ringback tone users.

[0053] like Figure 3 as well as Figure 4 As shown in the figure, if the user triggers the video call service, the user will be allowed to establish both 5QI1 and 5QI2 bearers during the resource reservation process. If the user triggers the video ringback tone service, only the 5QI1 bearer needs to be established during the resource reservation stage. In the subsequent UPDATE process, a 5QI2 bearer will be established to carry the video ringback tone service in the subsequent ringing process. When the called party picks up the phone, the 5QI2 bearer will be deleted.

[0054] Since both video calls and video ringback tone services will trigger the establishment of 5QI2 bearers, the way to trigger the switching of video call services through the 5QI2 bearer establishment process cannot be distinguished from the video ringback tone service. Based on the current mechanism, the switching function based on the video call service will mistakenly identify the user who has activated the video ringback tone service voice call as a video call user, and then mistakenly migrate the voice user from 700M to 2.6G (in fact, it is recommended that voice users stay in the 700M band and video users stay in the 2.6G band), which makes the service residence and migration logic chaotic, the network utilization rate is unbalanced, and users cannot stay in the most suitable network band, which ultimately makes the original "speech and digital stratification" and "speech and video stratification" strategies invalid.

[0055] Therefore, how to identify the video call service and the video ringback tone service and improve the switching efficiency of the video call service is a problem that needs to be solved urgently.

[0056] This application identifies the video ringback tone service and the video call service by determining whether the signaling message includes the establishment requirement information of 5QI2, and performs cell switching in the video call service according to the measurement report, so as to accurately identify the video call service and the video ringback tone service and improve the switching efficiency of the video call service.

[0057] It should be noted that the execution subject of this embodiment can be a video call service switching device, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a video call service switching device capable of realizing the above functions, etc., and this embodiment does not specifically limit this. The following takes the video call service switching device as the execution subject as an example to illustrate this embodiment and the following embodiments.

[0058] Based on this, the present application proposes a video call service switching method of the first embodiment, please refer to Figure 5 The video call service switching method includes steps S101 to S103:

[0059] Step S101, upon receiving a signaling message for establishing 5QI2, determining whether the signaling message includes establishment requirement information for 5QI1;

[0060] In this embodiment, when the 5G base station receives a signaling message sent by AMF (Access and Mobility Management Function), it first determines whether there is a need to establish 5QI2 in the signaling message. If so, that is, the signaling message is a signaling message for establishing 5QI2, it once again determines whether the signaling message includes the establishment requirement information of 5QI1, that is, determines whether the signaling message includes both the need to establish 5QI2 and the need to establish 5QI1.

[0061] Step S102: If the signaling message includes 5QI1 establishment requirement information, the measurement configuration information of the target frequency cell is sent to the user terminal corresponding to the signaling message, wherein the user terminal uploads the measurement report of each target frequency cell based on the measurement configuration information;

[0062] In this embodiment, if the signaling message includes the establishment requirement information of 5QI1, it is determined that the information message is a signaling message of the video call service. If the signaling message does not include the establishment requirement information of 5QI1, the subsequent process is executed based on the video ringback tone service, that is, the execution Figure 4 The signaling process of the video ringback tone service.

[0063] In this embodiment, after determining that the information message is a signaling message for the video call service, the measurement configuration information of the target frequency cell is sent to the user terminal corresponding to the signaling message. The user terminal performs measurement operations on each target frequency cell based on the measurement configuration information. Specifically, the measurement method in the relevant technology can be used to perform measurement operations on each target frequency cell, obtain a measurement report of each target frequency cell, and upload the measurement report of each target frequency cell to the 5G base station. For example, the measurement report of each target frequency cell is uploaded to the 5G base station through the service cell of the user terminal in the 5G base station.

[0064] Step S103: determining a target neighboring cell in each target frequency cell based on the measurement report, and performing a handover operation of the user terminal to the target neighboring cell.

[0065] In this embodiment, after obtaining the measurement report, the target neighboring area is determined in each target frequency cell according to the measurement report. Specifically, for each target frequency cell, the 5G base station obtains SSB_RSRP (Single Side Band-Reference Signal Receiving Power) in its corresponding measurement report, and based on the SSB_RSRP of each target frequency cell, a preset number of cells to be screened are screened out in the target frequency cell, and the target neighboring area is determined in the cells to be screened. For example, if the number of measurement reports is greater than the preset number, a preset number of cells to be screened with the largest SSB_RSRP are screened out in the target frequency cell; if the number of measurement reports is less than or equal to the preset number, each target frequency cell is used as a cell to be screened.

[0066] After determining the target neighboring cell, the 5G base station performs a handover operation of the user terminal to the target neighboring cell. Specifically, refer to Figure 2 , taking the target neighborhood as Figure 2The target frequency cell in the target neighboring cell is selected, and a handover request is initiated to the target base station where the target neighboring cell is located. The target base station replies with a handover confirmation message to the 5G base station. The service cell of the 5G base station sends a reconfiguration message to the user terminal, and the user terminal initiates a handover to the target neighboring cell. The user terminal completes access to the target neighboring cell and replies with a reconfiguration completion message to the target neighboring cell, thereby completing the handover of the user terminal to the target neighboring cell.

[0067] It should be noted that after the user terminal completes the handover to the target neighboring cell, the signaling process of executing the video call service through the target neighboring cell is as follows: Figure 3 shown.

[0068] In a feasible implementation manner, after step S101, the video call service switching method may further include step S104:

[0069] Step S104: If the signaling message does not include the establishment requirement information of 5QI2, the signaling process corresponding to the video ringback tone service is executed.

[0070] In this embodiment, if the signaling message does not include the establishment requirement information of 5QI1, the 5G base station executes the signaling process corresponding to the video ring back tone service, that is, executes the subsequent process based on the video ring back tone service, which can be specifically executed Figure 4 The signaling process of the video ringback tone service.

[0071] The video call service switching method proposed in this embodiment determines whether the signaling message for establishing 5QI2 includes the establishment requirement information of 5QI1 when the signaling message is received; then if the signaling message includes the establishment requirement information of 5QI1, the measurement configuration information of the target frequency cell is sent to the user terminal corresponding to the signaling message, wherein the user terminal uploads the measurement report of each target frequency cell based on the measurement configuration information; then, based on the measurement report, the target neighboring cell is determined in each target frequency cell, and the switching operation of the user terminal to the target neighboring cell is executed, and the video ringback tone service and the video call service are identified by whether the signaling message includes the establishment requirement information of 5QI2, and the cell switching in the video call service is performed according to the measurement report, so as to accurately identify the video call service and the video ringback tone service, and improve the switching efficiency of the video call service.

[0072] In a feasible implementation, step S103 may include steps S201 to S203:

[0073] Step S201, based on the measurement report, obtaining the SSB_RSRP corresponding to each target frequency cell;

[0074] Step S202, based on the SSB_RSRP, determining a preset number of cells to be screened in each target frequency cell;

[0075] Step S203: determine the target neighboring cell in the cells to be screened.

[0076] In this embodiment, the 5G base station obtains the SSB_RSRP corresponding to each target frequency cell based on the measurement report. For each target frequency cell, the 5G base station obtains the SSB_RSRP in its corresponding measurement report.

[0077] After obtaining the SSB_RSRP corresponding to each target frequency cell, the 5G base station determines a preset number of cells to be screened in each target frequency cell based on the SSB_RSRP. Further, in a feasible implementation, step S202 may include steps S2021 to S2022:

[0078] Step S2021, sorting the target frequency cells in descending order based on the SSB_RSRP to obtain a sorting result;

[0079] Step S2022: taking a preset number of target frequency cells in the sorting result as the cells to be screened.

[0080] In this embodiment, after obtaining the SSB_RSRP corresponding to each target frequency cell, each target frequency cell is sorted in descending order based on the SSB_RSRP to obtain a sorting result, that is, the SSB_RSRP of the first target frequency cell in the sorting result is the maximum value among all the SSB_RSRPs, and then, the first preset number of target frequency cells in the sorting result are used as cells to be screened, and the preset number of cells with the largest SSB_RSRP among all the target frequency cells are used as cells to be screened. Furthermore, if the number of cells in the sorting result is greater than the preset number, the first preset number of target frequency cells in the sorting result are used as cells to be screened, and if the number of cells in the sorting result is less than or equal to the preset number, all target frequency cells are used as cells to be screened.

[0081] In this embodiment, after the cells to be screened are determined, a target neighboring cell is determined in the cells to be screened. Further, in a feasible implementation manner, step S203 may include steps S2031 to S2032:

[0082] Step S2031, obtaining the PRB utilization rate of the neighboring cells corresponding to each of the cells to be screened;

[0083] Step S2032: determining the target neighboring cell in the cell to be screened based on the neighboring cell PRB utilization rate.

[0084] In this embodiment, after determining the cells to be screened, the neighboring cell PRB utilization rate corresponding to each of the cells to be screened is obtained. Specifically, the co-station cells and non-co-station cells among the cells to be screened are determined, wherein the co-station cells are cells belonging to the 5G base station, that is, the co-station cells and the service cells of the user terminal belong to the same base station, and the non-co-station cells are cells that belong to different base stations than the service cells of the user terminal. For the co-station cells, the 5G base station can directly obtain the corresponding neighboring cell PRB utilization rate, and for the non-co-station cells, the 5G base station obtains the corresponding neighboring cell PRB utilization rate through the Xn interface.

[0085] After obtaining the neighboring PRB utilization rate of each cell to be screened, the target neighboring cell is determined in the cell to be screened based on the neighboring PRB utilization rate. Specifically, the target neighboring cell is determined in the cell to be screened by the uplink PRB utilization rate and the downlink PRB utilization rate in the neighboring PRB utilization rate. In a feasible implementation, step S2032 may include steps a to d:

[0086] Step a, based on the sorting result, sequentially obtaining the current cell to be screened from the cells to be screened, and determining whether the current cell to be screened meets the preset conditions corresponding to the target neighboring cell based on the PRB utilization rate of the neighboring cell of the current cell to be screened;

[0087] Step b, if the current cell to be screened meets the preset conditions corresponding to the target neighboring cell, the current cell to be screened is used as the target neighboring cell;

[0088] Step c: if the current cell to be screened does not meet the preset condition corresponding to the target neighboring cell, then return to the step of sequentially obtaining the current cell to be screened from the sorting results.

[0089] In this embodiment, after obtaining the neighboring PRB utilization rate of each cell to be screened, the current cell to be screened is obtained in the cells to be screened in sequence based on the sorting result. For example, when the current cell to be screened is obtained for the first time, the current cell to be screened is the cell that is ranked first in the sorting result among the cells to be screened. After obtaining the current cell to be screened, based on the neighboring PRB utilization rate of the current cell to be screened, it is determined whether the current cell to be screened meets the preset condition corresponding to the target neighboring cell. In a feasible implementation manner, step a may include steps a1 to a2:

[0090] Step a1, obtaining the PRB utilization rate of the first neighboring cell in the uplink and the PRB utilization rate of the second neighboring cell in the downlink of the neighboring cell PRB utilization rate of the current cell to be screened;

[0091] Step a2, determine whether the PRB utilization rate of the first neighboring cell is less than a first threshold value, and whether the PRB utilization rate of the second neighboring cell is less than a second threshold value, wherein, if the PRB utilization rate of the first neighboring cell is less than the first threshold value and the PRB utilization rate of the second neighboring cell is less than the second threshold value, it is determined that the current cell to be screened meets the preset conditions corresponding to the target neighboring cell.

[0092] In this embodiment, the PRB utilization rates of the neighboring cells of the current cell to be screened, the PRB utilization rate of the first neighboring cell in the uplink and the PRB utilization rate of the second neighboring cell in the downlink are obtained, and it is determined whether the PRB utilization rate of the first neighboring cell is less than the first threshold value, and whether the PRB utilization rate of the second neighboring cell is less than the second threshold value. If the PRB utilization rate of the first neighboring cell is less than the first threshold value and the PRB utilization rate of the second neighboring cell is less than the second threshold value, it is determined that the current cell to be screened meets the preset conditions corresponding to the target neighboring cell, otherwise it is determined that the current cell to be screened does not meet the preset conditions corresponding to the target neighboring cell.

[0093] The first threshold value and the second threshold value may be reasonably set, for example, the first threshold value is 50%, and the second threshold value is 60%.

[0094] In summary, in this embodiment, if the current cell to be screened meets the preset conditions corresponding to the target neighboring cell, the current cell to be screened will be used as the target neighboring cell, and the target neighboring cell can be accurately determined by the neighboring cell PRB utilization rate, so as to switch the user terminal to a target frequency band cell with good enough signal strength and moderate load based on the video call service switching, thereby achieving the purpose of voice and video stratification while ensuring the perception of the video call service.

[0095] If the current cell to be screened does not meet the preset condition corresponding to the target neighboring cell, the process returns to the step of sequentially obtaining the current cell to be screened in the sorting results.

[0096] It should be noted that if all cells to be screened do not meet the preset conditions corresponding to the target neighboring cells, Figure 2 Cell switching is performed according to the service switching process in.

[0097] The video call service switching method proposed in this embodiment obtains the SSB_RSRP corresponding to each target frequency cell based on the measurement report; then determines a preset number of cells to be screened in each target frequency cell based on the SSB_RSRP; and then determines the target neighboring cell in the cells to be screened. The target neighboring cell can be accurately determined, so that the user terminal is switched to a target frequency band cell with good enough signal strength and moderate load based on the video call service switching, thereby achieving voice and video stratification while ensuring the purpose of video call service perception.
