[0058] The first embodiment of the method of the present invention: monitor the users accessing the IP multimedia subsystem through the access gateway, and the specific monitoring process is as follows:

[0059] The monitoring center issues a control command to the CSCF through the interface 201, which includes the monitored user ID and monitoring content. The CSCF obtains relevant information of the monitored user in the database according to the monitored user ID, and according to The content generates monitoring information, and the monitoring information includes the relevant information of the monitoring user, the monitoring content, the address of the monitoring center, etc.;

[0060] Since the user accesses the IP multimedia subsystem (ISDN terminal, simulated user terminal) through the access gateway, the CSCF can notify the corresponding AGCF of the interception information through the interface 101, and the AGCF notifies the A-MGF of the interception information throu...

[0063] The second embodiment of the method of the present invention: monitor the users who directly access the IP multimedia subsystem, and the specific monitor process is:

[0064] The monitoring center issues a control command to the CSCF through the interface 201, which includes the monitored user ID and monitoring content. The CSCF obtains relevant information of the monitored user in the database according to the monitored user ID, and according to The content generates monitoring information, and the monitoring information includes the monitoring content, the address of the monitoring center, etc.;

[0065] Since the intercepted user is a user who directly accesses the IP multimedia subsystem, the CSCF can send the interception information to the RACS through the interface 105, and the SPDF (service-based policy decision function) on the RACS notifies the interception information to the C-BGF through the interface 112 .

[0068] The third embodiment of the method of the present invention: the monitored user is a user interacting with other IP multimedia subsystem users, and the specific monitoring process is as follows:

[0069] The monitoring center issues a control command to the CSCF through the interface 201, which includes the monitored user ID and monitoring content. The CSCF obtains relevant information of the monitored user in the database according to the monitored user ID, and according to The content generates monitoring information, and the monitoring information includes the monitoring content, the address of the monitoring center, etc.;

[0070] Since the monitored user interacts with other IP multimedia subsystem users, the CSCF can send the monitoring information to the RACS through the interface 105, and the SPDF on the RACS notifies the monitoring information to the I-BGF through the interface 111;

[0071] If the user who is set to monitor takes actions such as registration a...

Abstract

The invention discloses a method and a system for realizing monitoring an IP multimedia subsystem. The method comprises: call control function arranges control for a monitored user according to requirement of a monitor center, and generates monitor information; the call control function informs the monitor information to a control function embodiment, then the control function embodiment informs the monitor information to a transmission function embodiment which is nether in the control function embodiment; the call control function monitors activity of the monitored user, and the activity of the monitored is reported to the monitor center by the call control function embodiment or other control function embodiments; and when the monitor center needs communication content, the transmission function embodiment sends the communication content to the monitor center. The system comprises: the monitor center, the call control function, the control function embodiment and the transmission function embodiment. The invention perfects existing real time monitoring for user services in the IP multimedia subsystem via processing necessary extending on existing mature interface in the existing IP multimedia subsystem.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the technical field of IP multimedia subsystem monitoring. Background technique [0002] In recent years, with the development of international political forms, the legal monitoring function has been paid more and more attention by the security departments of various countries, and has become a means of monitoring communication networks and obtaining information to ensure national security and obtain necessary national security information. effective means. Therefore, the security departments of many countries will force operators to provide monitoring functions. [0003] The IP Multimedia Subsystem is a general architecture that provides real-time and non-real-time IP multimedia services. Because it does not limit the underlying access technology and other characteristics, it has received extensive attention in the process of fixed and mobile network convergence. [0004...
