Method and system for down-link monitoring data

Abstract

This invention discloses a kind of monitoring data issuing method and system, including: management functions entities(ADMF),monitoring data processing entities,consigned call control functions entities(P-CSCF) and service call session control function entities(S-CSCF). This method includes: set the monitoring data processing entities in the IP Multimedia Subsystem; the monitoring data processing entities send the data carried in the monitoring instruction from the ADMF to the monitoring control net element in the IP Multimedia Subsystem. In this invention, the ADMF in the administer side do not have to do the complex structure maintenance, no matter how the S-CSCF And / or the P-CSCF is added, deleted, or mended. As the result, the work of the ADMF in the administer side is reduced, as well as the difficult of the ADMF business.

Description

technical field [0001] The present invention relates to monitoring technology, in particular to a method and system for delivering monitoring data in an IP Multimedia Subsystem (IMS). Background technique [0002] Lawful interception refers to the law enforcement behavior of the law enforcement agency (LEA), approved by the corresponding authorized agency, to monitor the communication business of the public communication network in accordance with the relevant national laws and public communication network industry norms. [0003] figure 1 It is a schematic diagram of the lawful interception model of the IMS network in the prior art. see figure 1 , In order to realize lawful interception in IMS network, 3GPP TS33.107 defines the lawful interception model for IMS network, the model includes: Judicial Enforcement Monitoring Equipment (LEMF), Lawful Interception Management Function (ADMF) entity, handover function ( DF) entity, Serving Call Session Control Function (S-CSCF) ...

Problems solved by technology

Moreover, when there are multiple S-CSCF entities and P-CSCF entities managed by the ADMF entity, in order to be able to send interception data to the S-CSCF entity and / or P-CSCF entity registered with the interception object, the ADMF entity must use the broadcast In this way, the interception instruction carrying the interception data is sent to all P-CSCF entities and / or S-CSCF entities configured by it, thus greatly reducing the data processing efficiency of the ADMF entity as the interception center

[0005] In addition, in the prior art, only the P-CSCF entity and the S-CSCF entity are used as the monitoring control network elements of the IMS domain, so that when a supplementary service event corresponding to the monitoring object occurs, the P-CSCF entity and the S-CSCF Entities cannot be informed of the occurrence of supplementary business events, so they cannot report the supplementary business events of the monitoring object to the DF entity, so that the law enforcement agency cannot monitor the supplementary business events of the monitoring objects in the IMS network, thus greatly reducing the legal status of the IMS network. Service quality of monitoring business
