Embodiment Construction

[0085] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0086] According to the processing method of the SIP protocol message in the service process based on the retry mechanism of the present invention, the SIP node performing the retry function will notify the forward node to reset the timing of the SIP protocol when the current request fails during the retry process. device and continue with this business.

[0087] The situation that the current request fails in the present invention may be: no final response returned by the backward node is received during the timing of the SIP timer, or a failed final response returned by the backward node is received.

[0088] Three preferred embodiments are given below to describe the present invention in detail.

[0089] First preferred embodiment:

Abstract

The invention discloses a method for processing a SIP protocol request in a business process based on a retry mechanism. In the method, after receiving the SIP session request, the SIP node executing the retry function forwards it to a backward node according to the retry rule The SIP session request, and start the SIP protocol timer for the request; if the SIP node that performs the retry function fails the current request, it forwards the SIP session request to the next backward node according to the retry rule, for the SIP node Request to start the SIP protocol timer, and send a reset timer notification to the forward node; the forward node restarts the SIP protocol timer according to the notification, and continues this service. The application of the invention can reduce the impact of the SIP protocol timer overtime processing on the business based on the retry mechanism, and ensure the normal operation of this type of business.

Description

technical field [0001] The invention relates to the processing technology of the SIP protocol request in the system service process using the SIP protocol as the session control protocol, in particular to a processing method of the SIP protocol request in the service process based on a retry mechanism. Background technique [0002] With the development of mobile communication technology, a single voice communication method cannot fully meet the needs of users, and a new multimedia communication method is required. This kind of multimedia communication is not only simple video and audio communication, but also includes instant messaging, co-location browsing, collaborative work, streaming media and other services, especially the integration of new communication methods and traditional voice services. Most of the session control systems based on Internet and telecommunication network integration use Session Initiation Protocol (SIP) as the session control protocol, such as IP ...
