Problems solved by technology

[0004] The technical problem to be solved by the present invention is aimed at the existing SIP communication service system, when the state of the SIP service process is normal but an abnormality occurs inside (that is, the process appears to be normal statically, but in fact cannot handle various requests and services) , the problem that VRRP protocol and process monitoring methods cannot recover from faults, propose a method of using calls to keep alive service processes and perform fault recovery in a SIP communication system, and a server with corresponding functions

Embodiment Construction

[0026] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] The present invention utilizes some features of SIP services, such as registration, calling, etc., to keep services alive, and combines with process monitoring to perform fault recovery, and utilizes the SIP protocol stack to perform protocol interaction, thereby further improving the reliability of the system. Sex and business availability.

[0028] In the present invention, the SIP server integrates one or more server processes, and also includes a proxy service process and a monitoring process. The SIP server is not restricted to use any hardware platform. The server processes that a SIP server can generally support at the same time include proxy service, authentication service and registration service.

[0029] like figure 2 shown. The monitoring process consists of three modules: monitoring module, fault recovery module, and ...

Abstract

The invention relates to a fault detecting and control method of an SIP service program, and discloses a restoring method of service process fault of an SIP server and an SIP server; the restoring method of service process fault of the SIP server comprises the following steps: a. a calling keep-alive module is provided in the monitoring process, and the calling keep-alive module uses a distributed user name in an SIP system and has corresponding function; b. the calling keep-alive module sends calling information periodically; and c. if receiving the response of fault calling, the calling keep-alive module informs the SIP server of starting a fault restoring program. The invention also provides an SIP server with the corresponding function. The invention uses certain characteristics of the SIP service, such as registration, calling and the like, to carry out keeping alive of the service, combines the mode of process monitoring to carry out fault restoration, and uses an SIP protocol stack to carry out protocol interaction, thus further improving the reliability of the system and the usability of the service.

Description

technical field [0001] The present invention relates to a communication service system based on SIP (Session Initiation Protocol, session initiation protocol), in particular to a fault detection and control method of a service program. Background technique [0002] In the SIP communication service system, the SIP server needs to provide different logical components, such as the registration service to provide the registration of the terminal equipment, the proxy service to provide the user's incoming and outgoing calls and to communicate with other SIP application services. These service processes are the core components in the SIP communication system. If there is a failure, various products (such as softphones, phones on voice gateways, IP phones, wireless IP phones, etc.) accessed by the terminal will not be able to perform normal registration and call, causing the system to crash. [0003] The current solution to the above faults is to use VRRP (Virtual Router Redundanc...
