Abstract

The invention provides a communication system and a monitoring method of a session border controller (SBC) and an assignment user server, which mainly comprises the following processes: a grouping domain network is accessed uniformly in an IP multimedia subsystem network to realize mutual communication through the SBC and is connected with a monitoring gateway through the SBC; when the monitoring is started, the monitoring gateway delivers monitoring indication to the SBC; the controlled object user is monitored by the SBC according to the monitoring indication; the relative monitoring information and the calling content of the controlled object users are obtained and reported to the monitoring gateway. Due to that only the SBC is required to be connected to the monitoring gateway to realize monitoring and the core network element of the IP multimedia subsystem network is not required to realize the monitoring function, the invention has low requirement to the monitoring gateway, small development cost for realizing the monitoring, low cost for developing, relatively simple networking and does not need cross products association.

Description

technical field [0001] The present invention relates to the technical field of interception, and more specifically, the present invention relates to a session border controller, a home user server, a communication system and an interception method. Background technique [0002] Monitoring refers to the law enforcement agency (Law Enforcement Agency) to monitor the communication services of the Public Telecommunications Network (Public Telecommunications Network) in accordance with relevant national laws and public telecommunications network industry norms upon approval of the corresponding Authorizing Authority. [0003] Currently, according to the IP Multimedia Subsystem (IMS) listening solution based on the Universal Mobile Telecommunications System (UMTS) packet domain defined in 3GPP, the telecom network element proxy CSCF (P-CSCF) and serving CSCF (S-CSCF) in the IMS domain It is only responsible for reporting the intercept related information (IRI) information of the c...
