Method for initializing filtering rule download and its processing system

Abstract

The invention provides a download and treatment system and a method of initial filtering rule, wherein, a calling conversation control function entity and a home subscriber server both support shared initial filtering rule set. The system includes: an initial filtering rule setup device, positioned on the side of the home subscriber server and used in the setting up of initial filtering rule activation list in business configuration data, in order to present the activate state relevant to the initial filtering rule of the shared initial filtering rule set; a download and treatment device, positioned on the side of the service calling conversation control function entity and used to download business configuration data from home subscriber server and obtaining the activate state of the initial filtering rule relevant to the shared initial filtering rule set in the activation list of the initial filter rule according to the business configuration data, as well as carrying out subsequent treatment.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to an initial filter rule (iFC, initial Filter Criteria) downloading and processing system and method, which can be used in an IP Multimedia Subsystem (IMS, IP Multimedia Core Network Subsystem). Background technique [0002] Currently, the 3rd Generation Partnership Project (3GPP, 3 rd Generation Partnership Project) has introduced the basic principles for IMS network and services, and adopts the idea of ​​separation of control and business. The IMS control layer does not provide services, but only provides functions such as triggering, routing, and billing necessary for the business layer, while the business is completely Provided by the business layer. [0003] Service triggering is an important function of the IMS control layer, and is implemented by a Serving Call Session Control Function (S-CSCF, Serving Call Session Control Function) of the IMS control laye...

Problems solved by technology

Therefore, if the iFC set associated with the DSAI is simultaneously contained or partly contained by the iFC set associated with the shared iFC set, in summary, there is overlap between the iFC set associated with the shared iFC set and the iFC set associated with the The shared iFC set is associated with the DSAI, then when the DSAI is inactive, the iFC associated with the DSAI in the shared iFC set will be blocked

At this time, if the shared iFC set is used when downloading user service configuration data, the blocked iFC will be incorrectly downloaded by the HSS

[0016] To sum up, the application of the current DSAI mechanism may cause the initial filtering rules to be incorrectly downloaded by the HSS due to the application of the shared iFC set. On the one hand, it affects the application of the DSAI mechanism and its application effect; The application and application effect of the shared iFC set
