Problems solved by technology

However, the QoS on the default bearer cannot be guaranteed. When the network is congested and the bandwidth of the air interface is tight, the messages on the default bearer cannot be scheduled. In this way, important information for SIP registration may not be transmitted, resulting in The SIP registration of the terminal fails, which affects voice and video services, especially in the case of heavy traffic, such problems are prone to occur

Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0028] figure 1 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 1 As shown, the session initiation protocol registration method implemented in this embodiment mainly includes:

[0029] Step 101. After receiving the successful login message, the private network terminal triggers the network side to establish a dedicated bearer for it.

[0030] The difference between this step and the existing solution is that instead of being triggered by the network side to establish a dedicated bearer for the dedicated terminal, the dedicated network terminal actively initiates the establishment of the dedicated bearer. Moreover, the timing of triggering the establishment of a dedicated bearer is also diff...

Abstract

The invention discloses an SIP (Session Initiation Protocol) registration method and device, and the method comprises the steps: a network side is triggered to build a dedicated bearer for a private network terminal after the private network terminal receives a login success message; and after the dedicated bearer is established, the private network terminal initiates SIP registration to a networkside by using the dedicated bearer. By applying the technical scheme disclosed by the invention, the success rate of SIP registration in a network congestion scene can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method and device for registering a session initiation protocol. Background technique [0002] Existing private network terminals under the 3GPP / WITTEN standard, the SIP messages that the terminal application layer needs to send are transmitted on the default bearer in the early stage. After the SIP registration is passed, the dispatcher (MDC) on the network side replies to the UE SIP message to the terminal. At the same time as the 200ok message, the core network is triggered to establish a dedicated bearer. [0003] During the process of implementing the present invention, the applicant found that: the existing SIP registration of private network terminals has the problem of SIP registration failure in a network congestion scenario. The specific reasons are analyzed as follows: [0004] The above-mentioned SIP message that needs to be sent in the early s...
