Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] As mentioned above, the current terminal registration method cannot completely solve the problem that the terminal cannot be registered in some cases, and brings the overhead of detecting the terminal. In the terminal registration method and system based on the SIP protocol provided by the embodiments of the present invention, a process of first canceling and then registering is adopted to ensure that the terminal can register.

[0033] method embodiment

[0034] According to the embodiment of the method of the present invention, a terminal registration method based on the SIP protocol is firstly provided. The network environment to which this method is appli...

Abstract

The invention discloses the terminal registration method based on SIP protocol and a system. The method comprises the following processing steps: in the cancellation course, user terminal initiates cancellation for user station, and the user station cancels all the linkage addresses corresponding to the user terminal; in the registration course, the user terminal initiates the registration for the user station, and the user station registers the current linkage address of the user terminal. With the invention, the problem that the user terminal can not register can be solved, which improves the user experience and can avoid the overhead caused by detection terminal. The invention has the advantage of relative huge theoretic and practical value.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal registration method and system based on Session Initiation Protocol (SIP for short). Background technique [0002] Session Initiation Protocol (Session Initiation Protocol, referred to as SIP) has been more and more favored by the industry due to its simplicity, easy expansion, and easy implementation, and has gradually become NGN (Next Generation Network, next-generation network) and IMS ( IP Multimedia Subsystem, the mainstream protocol in IP Multimedia Subsystem). With the emergence of a large number of client software supporting SIP, servers and softswitches based on SIP protocol, SIP protocol is increasingly favored by telecom manufacturers, operators and standard organizations. [0003] According to the SIP protocol, the user needs to initiate a registration request to the registration server, register the current contact address, and then make a call. The net...
