Method, system and device for triggering instant message

Abstract

The present invention discloses a method, system, and device that is triggered by instant messaging in IMS. This method includes: S-CSCF obtains the value of DLG-Id from the top Route head domain of the receiving request message. Among them, the DLG-IDDirectly characterize the status quo of the source end of the request message and the IFC; judge the source end of the request message according to the value of the DLG-ID, and get the status of the IFC match; according to the source end of the request message and IFCThe matching status is triggered.Therefore, the application of the present invention can make S-CSCF compatible with multiple businesses involving MESSAGE, and has no dependence on other meged elements. It can maintain the independence of S-CSCF as the IMS standard device.The use of the current business type and IFC use reduces the occupation of system memory, simplifies the processing process, and improves processing efficiency.

Description

Technical field [0001] The invention involves the method, system, and equipment of instant messaging in the Internet agreement multimedia subsystem, especially the Internet agreement multimedia subsystem. Background technique [0002] In the Internet Protocol Multimedia Subsystem (IMS), the processing requirements of the instant messaging requirements of service calling and call control functions (S-CSCF) are also different in different application scenarios.For example, in the basic point message (MESSAGE) business, since the final response message comes from the called terminal, during the processing process of MESSAGE, the instance created by S-CSCF when receiving the MESSAGE from the main terminal called the terminal isAlways exist; and in MESSAGE's storage forwarding business, the Instant Messaging (IM) server returns the response that the transaction has ended after receiving the MESSAGE, resulting in the S-CSCF from receiving the IM server from the IM server.After MESSAGE,...

AI Technical Summary

Problems solved by technology

[0009] In the prior art, when the S-CSCF is compatible with the basic point-to-point MESSAGE service and the store-and-forward service of MESSAGE, it needs to rely on the processing of the IM server. In this way, the S-CSCF It will no longer be an IMS standard device, and it cannot meet the requirements of docking with any AS to correctly process various services and lose its independence. In addition, the local instance needs to save the current service and IFC usage, occupying system memory, S- CSCF needs to query the locally saved instance according to the value of dlg-id, and then obtain the current business ownership and IFC usage from the instance. The processing process is complicated and takes a long time
