Abstract

The invention provides a method of initial filtering rule download and processing, which includes: users are configured with the shared initial filtering rule set and dynamic business activation information in the business configuration data in business reservation under the situation of CSCF and HSS supporting shared initial filtering rule set; users sign the business on AS and transmits the dynamic business activation information to HSS by AS; HSS dynamically selects explicit or implicit download or not download the initial filtering rule relevant to shared initial filtering rule set and downloads the business configuration data to CSCF, according to the actual application situation of the initial filtering rule set of the dynamic business activation information and the relevant initial filtering rule set relevant to the shared initial filtering rule set. CSCF replaces original initial filtering rule with specific initial filtering rule and guarantees the business configuration data, according to the specific initial filtering rule relevant to the shared initial filtering rule set inquiry and the shared initial filtering rule set in the business configuration data.

Description

technical field

[0001] The present invention relates to the communication field, and more specifically relates to an initial filter rule (iFC, initial Filter Criteria) downloading and processing method, which can be used in an IP Multimedia Subsystem (IMS, IP Multimedia Core Network Subsystem). Background technique

[0002] At present, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) has introduced the basic principles for IMS networks and services, and adopts the idea of ​​separation of control and services. The IMS control layer does not provide services, but only provides necessary services for the service layer. Functions such as triggering, routing, and billing, 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 layer. ...
