Abstract
The application discloses a Session Initiation Protocol (SIP) registration method and a device, wherein the method comprises the following steps: after receiving the login success message, the private network terminal triggers the network side to establish a private bearer for the private network terminal; after the dedicated bearer is established, the private network terminal initiates SIP registration to a network side by using the dedicated bearer. By applying the technical scheme disclosed by the application, the SIP registration success rate in the network congestion scene can be effectively improved.
Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a session initiation protocol registration method and apparatus.
Background
In the existing private network terminal, under the 3GPP/WITTEN system, an SIP message that a terminal application layer needs to send is transmitted on a default bearer at the early stage, and after the SIP registration is passed, a dispatcher (MDC) on a network side triggers a core network to establish a private bearer while replying a UE SIP 200ok message to the terminal.
In carrying out the present invention, applicants have discovered that: the existing SIP registration of the private network terminal has the problem of SIP registration failure in a network congestion scene. The specific reason is analyzed as follows:
the SIP message that needs to be sent in the previous period relates to important information for performing SIP registration, including a first piece of registration information (registration request) of SIP, SIP 401 (response of registration request) and a second piece of registration information (authentication response) of SIP. However, QoS on the default bearer cannot be guaranteed, and messages on the default bearer cannot be scheduled under the conditions of network congestion and air interface bandwidth shortage, so that important information for performing SIP registration may not be transmitted, which causes SIP registration failure of a private network terminal, and further affects voice and video services, and such problems easily occur particularly under the condition of large traffic.

fig. 2 is a schematic flowchart of implementation based on TAPP in the embodiment of fig. 1.
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.
Fig. 1 is a schematic flowchart of a method according to an embodiment of the present invention, and as shown in fig. 1, the session initiation protocol registration method implemented in this embodiment mainly includes:
The difference between this step and the existing scheme is that the dedicated bearer is not triggered by the network side to be established for the dedicated terminal, but the dedicated network terminal actively initiates the establishment of the dedicated bearer. In addition, in the aspect of triggering the time for establishing the dedicated bearer, the triggering time is also different from the triggering time of the network side, and here, the establishment of the dedicated bearer is triggered when the private network terminal successfully logs in, rather than triggering the establishment of the dedicated bearer only when the SIP registration passes. Therefore, after receiving the login success message, the private network terminal triggers the network side to establish the private bearer for the private network terminal, so that the information used for SIP registration can be transmitted on the private bearer later, the success rate of SIP registration can be improved by utilizing the reliability of the private bearer, especially, the success rate of SIP registration can be improved by utilizing the priority scheduling advantage of the private bearer in a network congestion scene, and the problem of SIP registration failure in the scene is effectively solved.
Preferably, considering that the SIP message is generated at the application layer of the terminal, in order to timely and accurately trigger the establishment of the dedicated bearer, the establishment of the dedicated bearer may be triggered by the application layer, that is, may be implemented by using the application of the application layer, and based on this purpose, the following method may be specifically adopted to trigger the network side to establish the dedicated bearer for the network side:
step a1, the special terminal sends an Active _ Pdp _ context _ Request message to a GPRS service support node SGSN by using a designated APP, where the Active _ Pdp _ context _ Request carries a QoS class identifier QCI of a special bearer.
Here, the Active _ Pdp _ context _ Request message is a Request message for triggering the network side to establish a dedicated bearer for the network side.
Step a2, the SGSN establishes the special load of the corresponding QCI for the special terminal according to the Active _ Pdp _ Contexet _ Request message.
In this step, the SGSN establishes a dedicated bearer of a corresponding QCI for the private network terminal according to an Active _ Pdp _ context _ Request message sent by the private network terminal. Preferably, in order to guarantee reliable transmission of the SIP information to the maximum extent, a dedicated bearer with the highest QoS level may be configured for the SIP information, that is, the QCI carried by the Active _ Pdp _ context _ Request is the highest QCI level, and specifically, in accordance with the existing system, the QCI of the highest QCI level is 69.
Preferably, the specified application may be an existing application for initiating group service (TAPP).
And 102, after the special bearer is established, the special network terminal initiates SIP registration to a network side by using the special bearer.
In this step, the specific implementation method of SIP registration is the same as the existing method, and is not described herein again.
Fig. 2 is a schematic diagram showing a specific flow for implementing the above method embodiment by using a TAPP of a private network terminal, where as shown in fig. 2, after receiving a login success message, an SipService module of the TAPP triggers a PdpContextManager module of the TAPP to initiate establishment of a private bearer to an SGSN network element on a network side, and then the SipService module initiates an SIP registration process, so that the initiation of the SIP registration process is implemented based on the private bearer, where the SIP registration process is the same as that of the existing technical solution.
Corresponding to the above method embodiment, the present application further provides a corresponding session initiation protocol registration apparatus, which is disposed in a private network terminal, and includes: a processor to:
after the private network terminal receives the login success message, triggering the network side to establish a private bearer for the private network terminal;
and after the establishment of the special bearer is completed, initiating SIP registration to a network side by using the special bearer.
Preferably, the processor is specifically configured to: triggering a network side to establish a special bearer for the network side, comprising:
the special terminal sends an Active _ Pdp _ Contexet _ Request message to a GPRS service support node SGSN by using a specified application APP, wherein the Active _ Pdp _ Contexet _ Request carries a QoS grade identifier QCI of a special bearer;
and the SGSN establishes a special bearer of a corresponding QCI for the private network terminal according to the Active _ Pdp _ Contexet _ Request message.
Preferably, the QCI carried by the Active _ Pdp _ context _ Request is the highest QCI level.
Preferably, the designated application is an application TAPP for initiating a cluster service.
Further, the present application provides a non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the steps of the session initiation protocol registration method as described above.
Further, the present application provides an electronic device comprising the non-volatile computer-readable storage medium as described above, and the processor having access to the non-volatile computer-readable storage medium.
