Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0018] In the next-generation network system architecture based on IMS (IP Multimedia subsystem), the present invention proposes a method for performing routing detection on IMS system network elements, including core network elements, application servers, and terminals, through the background. By gradually increasing max The value of -forwards is used to locate which network element fails. In actual use, first send a route detection message to a specific test destination device. If a response is received within a specific period of time, it indicates that the destination protocol stack is working normally, that is, the route test is successful. If it times out, it indicates which network element in the middle If a fault occurs, gradually increase the value of the max-forwards parameter to locate which network element is faulty.

[0019] In the IMS-b...

Abstract

The invention discloses a method for detecting a routing in an IP multimedia subsystem (IMS). Whether routing detection is successful is judged by the routing detection at a first stage, and an increasing max-forwards parameter value is added into a routing detection message by the routing detection at a second stage so as to position a failure network element. The method for detecting the routing can rapidly detect that whether a protocol stack of a server or a terminal normally works, displays a detection result to a user by a back stage and can position the middle railed network element by increasing max-forwards when the detection failure fails.

Description

technical field [0001] The invention belongs to the field of communication, and specifically relates to a method for detecting the reachability of routes between network elements of the IMS system in the background through a transmission mechanism of SIP signaling messages, which is different from the traditional two-layer link detection Yes, here is a three-layer routing detection method, and the test results can be displayed on the background. Background technique [0002] With the evolution of the telephone network architecture and the development of broadband technology, the evolution of the traditional telephone network to the next generation network (NGN) is an inevitable trend. The TISPAN plan represented by the European ETSI proposes that the IMS-based architecture is The main structure of NGN thinks that INS represents the direction of NGN network development. The IMS system uses the SIP protocol for end-to-end call control, which provides a technical basis for IMS...
