Problems solved by technology

[0019] By studying the ATA-based call establishment process in the above-mentioned IMS, it is found that the existing service trigger method based on the initial filter criterion iFC (initial Filter Criteria) greatly increases the delay of establishing an end-to-end session, reduces the throughput of the system, and reduces the QoS of IMS network

Embodiment Construction

[0056] In order to make the object, 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.

[0057] see image 3 , introducing three operation steps of a rule-based dynamic service triggering method for an IMS network of the present invention:

[0058] (1) Follow the RFC 3261 international standard to define a new SIP header. The name of the SIP header is: Trigger-Rule, which is used to implement various related functions that support subsequent filtering criteria sFC;

[0059] (2) Set and load the filtering criterion sFC based on the response of the initial request and subsequent requests, so that after the serving S-CSCF of the home network executes the initial request successfully matching the initial filtering criterion iFC and invokes the application server AS, if the subsequent If the condition of the filter criterion sFC is met, the S-CSCF can per...

Abstract

The invention relates to a dynamic service triggering method based on rules and used in an IMS network, which includes three operation steps: (1) complying with international communication standard and define a new SIP head: Trigger-Rule, used to realize all relevant functions supporting subsequent filter criterion sFC; (2) setting up and load response based on initial request and subsequent request filter criterion; after S-CSCF executes the initial request successfully matched with iFC and invokes AS, if the sFC conditions is satisfied, S-CSCF can perform relevant operations according to the processing mode described by sFC; (3) utilizing the SIP head Trigger-Rule based on sFC, and S-CSCF performs a dynamic business trigger method based on rules. The invention is realized based on subsequent filter criterion sFC, can greatly improve ATA business trigger flexibility, effectively reduce S-CSCF and AS signaling flow, increase the throughout of the whole system, obviously reduces call setup time delay and improves IMS network service quality.

Description

technical field [0001] The invention relates to a rule-based dynamic service triggering method for an IMS network, belonging to the technical field of communication. Background technique [0002] The IP Multimedia Subsystem IMS (IP Multimedia Subsystem) is a new core network domain of an all-IP architecture proposed by the 3GPP (3rd Generation Partnership Project). The difference between the IMS service provision method and the traditional public switched telephone network PSTN (Public Switched Telephone Network) and the public land mobile network PLMN circuit domain service provision method is that in the IMS network, the control layer and the service layer are completely separated, and the control layer It does not provide services, it only provides the necessary triggering, routing, billing and other functions of the business layer, and the business is completely provided by the business layer. In the IMS network, the home network provides service execution, that is, whe...
