Problems solved by technology

[0007] However, using this method, the mobile client will frequently send registration refresh messages, which will consume the resources of the mobile terminal, such as network resources, power and system resources, resulting in short standby time of the mobile terminal, fast traffic consumption, and poor system performance.

Abstract

A unified communication passive SIP call system and the system obtain the connection information of the called client from the IM server according to the active SIP call request; when the connection status of the called client is online, the passive SIP call request is sent to the called client. Since the connection information used in the method and the system is provided by the IM server, the SIP server does not need to periodically refresh to update the connection information, reducing the burden on the SIP server; meanwhile, the client does not need to periodically send connection updates command, which saves client resources and improves the performance of the client; in addition, the IM server only needs to update the connection information stored in the IM server when the client performs network switching; finally, the above-mentioned unified communication passive SIP call method And the SIP server in the system does not need to update the connection information, and directly calls the connection information in the IM server. In summary, the performance of the whole system is good.

Description

technical field [0001] The present invention relates to the communication field, in particular to a unified communication passive SIP calling method and system. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is a multimedia communication protocol formulated by IETF (Internet Engineering Task Force, Internet Engineering Task Force). SIP is a text-based application layer control protocol used to create, modify and release sessions of one or more participants, widely used in CS (Circuit Switched, circuit switching), NGN (Next Generation Network, next-generation network) And in the network of IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). [0003] The SIP registration mechanism allows a user agent to identify itself to a registration server, which is a device used to locate a user (specified by an address of record). To meet security requirements, the SIP server does not allow unregistered users to initiate calls. SIP reg...
