Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
The embodiment of the application discloses a method for establishing a special bearer, as shown in fig. 1, the method comprises the following steps:
In this step, the UE needs to obtain a mapping relationship between the identifier of the called object and the application priority of each preset service type from the network side in advance. The mapping relation is used for describing the mapping relation between the called object identification and the application priority under a certain service type, so that the UE can inquire the mapping relation according to the called object identification and the service type of the service to be performed, acquire the corresponding application priority and further inform the network side to establish the corresponding special bearer according to the application priority.
Here, the specific service types are divided into several major categories, such as a key voice service (MCPTT), a key task data (MCData) service, and a key task video (MCVideo) service, and the following major categories may be divided into two categories, namely a point call and a group call. Application priority in this application refers to the priority of an application specific to each subclass.
In practical applications, the service type related to the mapping relationship may be specified by those skilled in the art according to practical application needs.
In a mission critical push-to-talk (MCPTT) system, when the service type is a point call service of a key voice service, the called object is an MCPTT user, and when the service type is a group call service of the voice service, the called object is an MCPTT group.
For MCData and MCVideo services, a mapping relationship between corresponding user identifiers and application priorities may also be defined, specifically, under the point call service type of MCData, a called object is an MCData user; under the MCvideo point call service type, the called object is a called MCvideo user, and under the MCdata group call service type, the called object is a called MCdata group; under the MCvideo group calling service type, the called object is a called MCvideo group.
Specifically, a person skilled in the art may set the called object related to the mapping relationship according to an application of a service according to actual needs.
In practical applications, the mapping relationship is pre-stored in a network side, such as a configuration management server. Preferably, the network side may utilize an application priority cell of a newly added service to carry the mapping relationship in a key task service user configuration (MC service user profile) data, so as to send the mapping relationship to the UE. The specific process is as follows:
when the UE is accessed to the system, the UE serves as a configuration management client to send a configuration request for acquiring a key task service user to a configuration management server on a network side;
and the configuration management server sends a corresponding key task service user configuration acquisition response according to the key task service user configuration acquisition request, wherein the mapping relation is carried in the key task service user configuration acquisition response.
Further, in order to ensure the accuracy of the mapping relationship stored on the UE side, when the mapping relationship in the network side changes, the UE needs to be notified to perform corresponding update, which is specifically as follows:
when the mapping relation in the system is changed, the configuration management server notifies the changed mapping relation to the UE, and triggers the UE to update the local mapping relation.
102, when the UE needs to initiate a service, inquiring the mapping relation according to the service type of the current initiated service and the identification of the called object to obtain a corresponding application priority; and carrying the application priority in a message which is sent to a network side and used for triggering the establishment of the special bearer so as to trigger the network side to establish the corresponding special bearer according to the application priority.
In this step, the UE may determine the application priority corresponding to the currently initiated service according to the locally stored mapping relationship between the identifier of the called object and the application priority in each preset service type, and notify the network side, so that the network side may establish a corresponding dedicated bearer according to the application priority, thereby meeting the requirement of the user for establishing the dedicated bearer by differentiating the service application.
Preferably, in a mission critical push-to-talk (MCPTT) system, the message triggering establishment of the dedicated bearer at least includes a point-call request MCPTT private call request message, a Group call request message, a Group join request message, and a broadcast Group call request Group-broadcast Group call request message, but is not limited to the above messages as long as the message can trigger establishment of the dedicated bearer at the network side.
When the invention is applied to a 3GPP MC standard protocol system, the MC Service server can specifically establish corresponding special load for the Service as the existing system.
Corresponding to the above method embodiment, an embodiment of the present application further discloses a user equipment, including: a processor to:
acquiring a mapping relation between the identifier of a called object and the application priority of each preset service type from a network side in advance; the called object is a user or a group;
when a service needs to be initiated, inquiring the mapping relation according to the service type of the currently initiated service and the identification of the called object to obtain the corresponding application priority; and carrying the application priority in a message which is sent to a network side and used for triggering the establishment of the special bearer so as to trigger the network side to establish the corresponding special bearer according to the application priority.
Preferably, the processor is specifically configured to:
when the user equipment is accessed to the system, the configuration management client sends a request for obtaining the configuration of the key task service user to a configuration management server at a network side so as to trigger the configuration management server to send a corresponding response for obtaining the configuration of the key task service user according to the request for obtaining the configuration of the key task service user, wherein the response for obtaining the configuration of the key task service user carries the mapping relation.
Preferably, the processor is further configured to: when the mapping relation in the system is changed, the local mapping relation is updated according to the changed mapping relation notified by the configuration management server.
Preferably, in the mission critical push-to-talk MCPTT system, the message triggering establishment of the dedicated bearer at least includes a point-call request MCPTT private call request message, a Group call request message, a Group join request message, and a broadcast Group call request Group-broadcast Group call request message.
Furthermore, the present application also provides a non-transitory computer readable storage medium storing instructions, which when executed by a processor, cause the processor to execute the steps of the method for establishing a dedicated bearer as described above.
Furthermore, an electronic device is provided in an embodiment of the present application, which includes the aforementioned nonvolatile computer-readable storage medium, and the processor having access to the nonvolatile computer-readable storage medium.
It should be noted that the present invention can be applied to a mission-critical MC system to satisfy the requirement of the MC Service server in the system to differentiate Service applications to establish corresponding dedicated bearers for services, but is not limited to this in practical application, and the present application can be applied as long as the system has the requirement to differentiate Service applications to establish corresponding dedicated bearers for services.
