Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
At the initial stage of 5G networking, operators may adopt NSA (Non-standard) Non-independent networking architecture networking or SA (standard) independent networking, or even NSA/SA mixed networking architecture according to their own condition restrictions (for example, consideration of coverage, user perception, investment cost, and other comprehensive factors). For voice and video services, the bearer under the 5G NSA networking is completed by VOLTE, and the bearer under the 5G SA networking is completed by VONR. Therefore, in view of the characteristics of the NSA and SA networking, there is a current situation where a 5G cell supporting VONR and a cell not supporting VONR coexist during a long period from the initial 5G.
In the process that a mobile terminal initiates the handover to a target cell which does not support VONR under the voice or video service in a source 5G cell which supports VONR, the currently adopted technical scheme is as follows: the mobile terminal reports a measurement report according to network measurement and configuration to perform same-frequency switching, multiple switching failures of the terminal can be caused because the target base station does not support the VONR service, and then the different systems are switched until a 5G to 4G different system switching threshold is triggered, so that the continuity of the service can be maintained.
The existing scheme has the defects that multiple measurement reports of the terminal exist in 5G co-frequency switching, but the switching fails, which causes unnecessary overhead of switching signaling, and the switching of different systems of the terminal cannot be performed until a 5G to 4G different system switching threshold value is triggered. In severe cases, the problems of terminal service blocking, disconnection and the like can be caused, and the perception of a client is directly influenced.
In order to overcome the above-mentioned drawbacks, an embodiment of the present application provides a communication method, which is applied to a source base station supporting a first service and is shown in fig. 1, where the method includes the following steps:
Wherein the target service is supported by the first service.
In this embodiment, the source base station is a communication base station for providing the first service, and the mobile terminal device currently establishes a communication connection with the source base station, that is, the source base station currently provides a communication service for the mobile terminal device, and the mobile terminal device is currently using a target service provided by the source base station.
The mobile terminal equipment detects the signal intensity of a service signal received from a source base station, generates a switching request for requesting the source base station to switch the base station and requesting to switch to a target base station when the signal intensity of the source base station is lower than the preset intensity and detects that the signal intensity of the target base station is higher than the preset intensity, and then sends the switching request to the source base station.
Wherein the service handover request comprises at least a request instructing the target base station to provide the first service for the mobile terminal device.
In the embodiment of the application, the source base station receives the switching request sent by the mobile terminal device, and after determining that the target base station is obtained from the switching request, generates the service handover request and sends the service handover request to the target base station, so that the base station switching between the source base station and the target base station is realized, and the stable service is provided for the mobile terminal device.
The target response message is a message generated by the target base station in response to the service handover request and used for indicating that the target base station does not support the first service, and the handover response message is used for indicating the mobile terminal equipment to trigger the fallback operation of the handover from the first service to the second service capable of supporting the target service.
In the embodiment of the application, after receiving a service handover request sent by a source base station, a target base station determines whether a first service can be provided according to the service handover request, and obtains a determination result. And the target base station determines whether to generate a target response message according to the judgment result. If the judgment result shows that the target base station can provide the first service, the target base station sends a response message for indicating the service handover request to the source base station, so that the source base station indicates the mobile terminal equipment to be switched to the target base station; and if the judgment result shows that the target base station can not provide the first service, the target base station generates a target response message and sends the target response message to the source base station, so that the source base station informs the mobile terminal equipment to trigger a fallback operation of switching from the first service to a second service capable of supporting the target service based on the target response message.
In the communication method provided by the embodiment of the application, if a handover request sent by a mobile terminal device currently establishing a first service with the source base station and being in a target service is received, the source base station determines the target base station based on the handover request and sends a service handover request to the target base station, and if the source base station receives a target response message sent by the target base station, the source base station responds to the handover request based on the target response message and sends the handover response message to the mobile terminal device. Therefore, after receiving a switching request sent by the mobile terminal equipment, the source base station sends a service handover request to the determined target base station, and after receiving the service handover request, the target base station directly generates a target response message which does not support the first service and sends the target response message to the source base station, so that the source base station indicates subsequent operation to the mobile terminal equipment according to the target response message, the problem of high signaling consumption in the current 5G to 4G signal switching process is solved, a method for realizing timely switching by using less signaling is provided, the possibility of service interruption caused by untimely switching is reduced, and the switching success rate is improved.
Based on the foregoing embodiments, an embodiment of the present application provides a communication method, which is applied to a target base station that does not support a first service, and is shown in fig. 2, where the method includes the following steps:
The service handover request is used for requesting the target base station to provide the first service for the mobile terminal equipment.
In the embodiment of the present application, the target base station and the source base station may communicate with each other, and the communication mode includes a wireless communication mode. After the source base station generates the service handover request, the source base station sends the service handover request to the target base station, so that the target base station can receive the service handover request sent by the source base station.
Wherein the target response message is used for indicating that the target base station does not support the first service.
In the embodiment of the application, the target base station parses the service handover request, and determines that the source base station requests the target base station to provide the first service for the mobile terminal device, and therefore, the target base station generates the target response message because the target base station cannot provide the first service.
And step 203, sending the target response message to the source base station.
In the embodiment of the application, the target base station sends the target response message to the source base station, and the target base station informs the source base station that the target base station cannot provide the first service through the target response message, so that the source base station executes subsequent other operations according to the target response message, and the service corresponding to the high-quality and stable target service is provided for the mobile terminal device.
In the communication method provided by the embodiment of the application, after receiving a service handover request sent by a source base station, a target base station generates a target response message based on the service handover request and sends the target response message to the source base station, so that if the source base station receives the target response message sent by the target base station, the source base station responds to a handover request based on the target response message and sends the handover response message to a mobile terminal device. Therefore, after receiving the service handover request, the target base station directly generates a target response message which does not support the first service and sends the target response message to the source base station, so that the source base station indicates the subsequent operation to the mobile terminal device according to the target response message, the problem of higher signaling consumption in the current 5G to 4G signal switching process is solved, a method for realizing timely switching by using less signaling is provided, the possibility of service interruption caused by untimely switching is reduced, and the switching success rate is improved.
Based on the foregoing embodiments, an embodiment of the present application provides a communication method, which is shown in fig. 3 and includes the following steps:
step 301, if receiving the handover request, the source base station parses the handover request to obtain the target identity information of the target base station detected by the mobile terminal device.
In the embodiment of the present application, a source base station is taken as a 5G base station capable of providing a VONR service, and a mobile terminal is taken as an example to describe a smart phone, where the current source base station provides a VONR service for the smart phone, and the smart phone is currently in a video service state or a voice service state, at this time, the smart phone detects the received signal intensity of the source base station according to a signal detection item sent by the source base station, generates a corresponding detection report, generates a switching request according to the detection report, and sends the switching request to the source base station, so as to implement intra-system intra-frequency switching. And the source base station analyzes the switching request and determines to obtain the target identity identification information of the target base station detected by the mobile terminal equipment. The target identity information is identification information for uniquely identifying the target base station, and may be, for example, a base station number, a base station name, and the like of the target base station. It should be noted that, because intra-system intra-frequency handover is implemented, it can be determined that the target base station also belongs to the 5G base station.
Step 302, the source base station determines the target base station based on the target identity information.
In the embodiment of the application, the source base station determines the target base station according to the target identity identification information obtained by determination, and establishes communication connection with the target base station.
Step 303, the source base station sends a service handover request to the target base station.
Wherein the service handover request comprises at least a request instructing the target base station to provide the first service for the mobile terminal device.
In the embodiment of the application, after the communication connection is established between the source base station and the target base station, the source base station sends the generated service handover request to the target base station. The service handover request may include the following messages: protocol Data Unit (PDU) identity identification Information (ID), tunnel Endpoint Identifier (TEID), quality of Service Class Identifier (QCI), global Unique Authentication Management Function identification information (GUAMI), and the like.
Step 304, the target base station receives the service handover request sent by the source base station.
The service handover request is used for requesting the target base station to provide the first service for the mobile terminal equipment.
Step 305, the target base station generates a target response message based on the service handover request.
The target response message is used for indicating that the target base station does not support the first service.
In an embodiment of the present application, the first service may be a VONR service. After receiving the service handover request sent by the source base station, the target base station determines that voice service or video service under the VONR service needs to be provided for the smart phone currently, but the target base station can not provide the VONR service, so the target base station generates a target response message.
Step 306, the target base station sends a target response message to the source base station.
In the embodiment of the application, the target base station directly sends the target response message to the source base station to inform the source base station that the first service cannot be supported, so that the service handover request sent by the source base station is directly responded, the interaction process between the source base station and the target base station is reduced, and the communication efficiency between the source base station and the target base station is improved.
Step 307, if receiving the target response message sent by the target base station, the source base station responds to the handover request based on the target response message, and sends a handover response message to the mobile terminal device.
The target response message is a message which is generated by the target base station in response to the service handover request and is used for indicating that the target base station does not support the first service, and the handover response message is used for indicating the mobile terminal equipment to trigger the fallback operation of the handover from the first service to the second service capable of supporting the target service.
In this embodiment, the second service may refer to a Voice over Long-Term Evolution (VOLTE) service provided by 4G. The fallback operation to switch from the first service to the second service capable of supporting the target traffic may be, for example, a fallback operation that triggers a 5G switch to a 4G. After receiving the target response message sent by the target base station, the source base station parses the target response message, determines that the target base station cannot support the first service, i.e., determines that the target base station does not support the VONR service, and then, in order to respond to the handover request, the source base station generates a handover response message and sends the handover response message to notify the mobile terminal device that there are no base stations capable of providing the VONR service around the source base station, which requires the mobile terminal device to trigger a fallback operation for switching from the first service to a second service capable of supporting the target service. Therefore, the mobile terminal equipment searches for a proper 4G base station to provide VOLTE service, and voice service or video service of the mobile terminal equipment is guaranteed.
Based on the foregoing embodiments, in other embodiments of the present application, step 305 may be implemented by steps 305a to 305 c:
step 305a, the service handover request is analyzed to obtain an analysis result.
In the embodiment of the application, the service handover request is analyzed to obtain an analysis result.
Step 305b, if the analysis result indicates that the requested service is the first service, determining target identification information for indicating that the first service is not supported.
In the embodiment of the present application, when the analysis result for the service handover request indicates that the source base station requests to provide the first service, the target base station determines target identification information agreed with the source base station to indicate that the first service cannot be supported, because the target base station cannot support the first service. Illustratively, 0 or 1 may be used as the target identification information that cannot support the first service.
Step 305c, generating a target response message based on the target identification information.
In the embodiment of the present application, the generated target response message includes the target identification information, so that the source base station can quickly know that the target base station does not support the first service by detecting the target identification information included in the target identification message.
Based on the foregoing embodiments, in other embodiments of the present application, step 305c may be implemented by steps a11 to a 12:
and a11, acquiring a reference response message.
In the embodiment of the present application, the reference response message is a response template message for responding to the service handover request, wherein some fields need to be filled according to the actual situation of the target base station.
Step a12, setting the target field in the reference response message as target identification information to obtain a target response message.
In the embodiment of the present application, the reference response message is provided with a target field for identifying whether the target base station supports the first service, and the target field may be set as corresponding identification information according to an actual situation that whether the target base station supports the first service or not.
Taking the example that the target identification information indicating that the first service is not supported is 0 and the identification information supporting the first service is 1, when it is determined that the target base station does not support the first service, the target field in the reference response message is set to 0, so that a target response message can be obtained; and when the target base station is determined to support the first service, setting the target field in the reference response message to be 1, thus obtaining the response message supporting the first service.
Based on the foregoing embodiments, in other embodiments of the present application, step 307 may be implemented by steps 307a to 307 c:
step 307a, if receiving the target response message sent by the target base station, the source base station analyzes the target response message to obtain the setting information set in the target field of the target response message.
In the embodiment of the application, after receiving the target response message sent by the target base station, the source base station analyzes the target response message, and determines the setting information corresponding to the target field from the target response message.
Step 307b, if the setting information is the target identification information, the source base station responds to the handover request and generates a handover response message.
In the embodiment of the application, the setting information is determined, and if the setting information is the target identification information, the source base station responds to the handover request and generates a handover response message for instructing the mobile terminal device to trigger the fallback operation.
Step 307c, the source base station sends a handover response message to the mobile terminal device.
In the embodiment of the application, the source base station sends the handover response message to the mobile terminal device, and controls the mobile terminal device to execute the fallback operation.
Based on the foregoing embodiments, an embodiment of the present application provides a communication method, an implementation flow of the communication method may be shown in fig. 4, and includes the following steps:
The terminal belongs to the mobile terminal device.
The service handover request may be, for example, a handover request, which may carry information such as a PDU Session ID, a TEID, a QCI, and a GUAMI.
The target response message may be, for example, a handover prediction failure, where a target field von _ switch =0 is carried, and von \uswitch =0 is used to identify that the target base station does not support the VONR service.
Among them, the FallBack operation from 5G to 4G is EPS FallBack.
And step 406, after the terminal fall-back operation is successful, continuing to perform voice or video service in the 4G communication mode, and after the terminal voice or video call is finished, returning the terminal to the 5G mode through a quick return flow.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.

Therefore, after receiving a switching request sent by mobile terminal equipment, a source base station sends a service handover request to a determined target base station, and after receiving the service handover request, the target base station directly generates a target response message which does not support the first service and sends the target response message to the source base station, so that the source base station indicates subsequent operation to the mobile terminal equipment according to the target response message, the problem of larger signaling consumption in the current 5G to 4G signal switching process is solved, a method for realizing timely switching by using less signaling is provided, the possibility of service interruption caused by untimely switching is reduced, and the switching success rate is improved.
