Embodiment Construction

[0030] To make the object, technical solution and advantages of the present invention more clear, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Figure 1 Schematic diagram of the method flow for embodiments of the present invention, e.g., Figure 1 As shown, the SIP registration method of the cluster terminal implemented in this embodiment mainly comprises:

[0032] Step 101, when the terminal receives a SIP registration failure message after initiating the Session Initiation Protocol (SIP) registration, the reason for the registration failure is resolved from the SIP registration failure message.

[0033] In this step, in order to solve the problem that sip registration cannot always succeed due to the inconsistency between the terminal and the token in the server, it is necessary to analyze the reasons for SIP registration failure, distinguish different failure conditions, and handl...

Abstract

The present application discloses a SIP registration method and device for a cluster terminal, wherein the method includes: when the terminal receives a SIP registration failure message after initiating the SIP registration, parsing out the registration failure from the SIP registration failure message Reason; when the reason for the registration failure is token verification failure, the terminal obtains a token again from the network side, and uses the obtained token to perform SIP registration again. Applying the technical solution disclosed in this application can effectively solve the problem that SIP re-registration always fails after the TOKEN verification fails.

Description

Technical field [0001] The present application relates to the field of communication technology, in particular to a cluster terminal session initiation protocol (SessionInitiation Protocol, SIP) registration method and apparatus. Background [0002] Under the existing Mission Critical Push To Talk over LTE (MCPTT) model, the implementation of endpoint login and SIP registration is: [0003] The terminal authenticates and logs in to the User And Device Controller (UDC), and upon success, the UDC issues a token (TOKEN) to the terminal's operation management (OM) module. The OM module issues a successful login broadcast, triggering the SIP module to register SIP with the Multimedia Dispatcher Center (MDC). Before SIP registration, the SIP module obtains tokens from the OM module and carries it in the SIP register (SIP REGISTER) message to the MDC. After the MDC receives the SIP REGISTER message, it will parse the user information and token, and obtain the token information of this u...
