Abstract

The invention discloses a method for monitoring a terminal and a communication system. The method comprises the following steps that: user access equipment receives a control signaling which is transmitted by a management entity, wherein the control signaling comprises the identifier of the terminal to be monitored; and the user access equipment acquires the monitoring data of the terminal according to the control signaling so as to monitor the communication service of the terminal. In the embodiment of the invention, by transmitting the control signaling to the user access equipment and monitoring the terminal through an access gateway or access point equipment, the problem that communication data and signaling data which do not pass through a core network cannot be monitored in the prior art is solved, and the aim of monitoring various types of communication services of the terminal by a law enforcement agency (LEA) is fulfilled.

Description

technical field [0001] The invention relates to communication technology, in particular to a terminal monitoring method and a communication system. Background technique [0002] Legal monitoring is the ability of the mobile communication system to monitor the communication content of terminals and monitor related information (Intercept Related Information, hereinafter referred to as IRI) provided by the mobile communication system for the benefit of the Law Enforcement Agency (hereinafter referred to as LEA). The terminal may be a mobile phone, a data card, an access point (Access Point, hereinafter referred to as AP) device, and the like. [0003] In the communication mobile network, logical entities related to monitoring include various network nodes such as Mobile Switching Center (hereinafter referred to as MSC), General Packet Radio Service Support Node (hereinafter referred to as GSN) , the GSN includes a GPRS Serving Support Node (Serving GPRS Support Node, hereinaft...
