Abstract

The present invention discloses a method for transmitting legal monitoring information. The method comprises the monitoring information carried in the information relevant to the monitoring object, and the network function entity transmitted to the participated monitoring object conversation; the network function entity performs monitoring to the monitoring object according to the received monitoring information, and reports the relevant monitoring information IRI and / or the communication content CC to the law-enforcing institution. The method provided by the present invention can reduce the working quantity of the ADMF management and the network function entity maintenance and the possibility of the data leakage.

Description

technical field [0001] The invention relates to the field of lawful interception, in particular to a method for transmitting lawful interception information. Background technique [0002] Lawful interception is a law enforcement act conducted by law enforcement agencies to monitor public communication services in accordance with relevant national laws and public communication network industry norms with the approval of relevant authorized agencies. [0003] In order to realize the lawful interception in the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) network, the 3GPP TS33.107 standard defines the lawful interception model for the IMS network, see for details figure 1 , the model includes: judicial enforcement monitoring equipment (LEMF, Law EnforcementMonitoring Facility), lawful interception management function (ADMF, Administration Function) entity, transfer function (DF, Delivery Function) entity, service call session control function (S-CSCF, Serving-Call Se...
