Embodiment 1

[0041] figure 2 It is a schematic flow chart of Embodiment 1 of the monitoring method of the present invention. This method may be executed by the NE, such as figure 2 As shown, the monitoring method of this embodiment may include the following steps:

[0042] Step 201, when the communication service performed by the terminal is monitored, obtain the user identification corresponding to the communication service;

[0043] The NE monitors the communication service performed by the terminal. For example, the communication service may be the call service received by the NE, or the user location registration and power-on / off operation service handled by the NE, and the short message sending service obtained by the NE.

[0044] Step 202: Send a monitoring data request message to the monitoring gateway, where the monitoring data request message includes the user identifier, so as to trigger the monitoring gateway to perform monitoring services according to the monitoring data req...

Embodiment 2

[0050] image 3 It is a schematic flow chart of Embodiment 2 of the monitoring method of the present invention. This embodiment is based on Embodiment 1 and further illustrates the operation of the NE after sending the monitoring data request message; image 3 As shown, the method may include the following steps:

[0051] Step 301, when the communication service performed by the terminal is monitored, obtain the user identification corresponding to the communication service;

[0052] Wherein, in addition to obtaining the user identification corresponding to the communication service, when the NE monitors the communication service performed by the terminal, it can also obtain corresponding service information according to different types of communication services.

[0053] For example, if the communication service is a short message service, the user number and content of the short message can be obtained; if the communication service is a location registration and power on / of...

Embodiment 3

[0067] Figure 4 It is a schematic flow chart of Embodiment 3 of the listening method of the present invention, the method may be executed by LIG, such as Figure 4 As shown, the monitoring method of this embodiment may include the following steps:

[0068] Step 401, receiving the monitoring data request message sent by the monitoring device, the monitoring data request message including the user identification corresponding to the communication service;

[0069] The LIG receives the monitoring data request message sent by the NE, and the message carries the user identifier obtained when the NE monitors the communication service of the terminal.

[0070] Step 402, when it is determined according to the user identifier that there is interception data corresponding to the user identifier, obtain interception information corresponding to the user identifier and report to the interception center.

[0071] Specifically, the LIG may query whether the local database stores the inte...

Abstract

The embodiment of the invention provides interception equipment, an interception method and an interception system. The interception method comprises the following steps of: acquiring user identification corresponding to a communication service when the communication service performed by a terminal is intercepted; and transmitting an interception data request message to an interception gateway, wherein the interception data request message comprises the user identification and a service type of the communication service so as to trigger the interception gateway to execute an interception service according to the interception data request message. In the interception equipment, the interception method and the interception system, the interception data request message is transmitted to a lawful interception gateway (LIG) through a network element (NE) so as to query whether the user identification is intercepted, and the NE intercepts according to the interception data returned by the LIG, and the like, so that the NE side does not store the interception data of a user any more, the problem that an interception data leakage risk is absent on the NE side is solved, and the safety of the user interception data is guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a monitoring device, a monitoring method and a system. Background technique [0002] Lawful interception refers to the monitoring of a user's communication process by national security agencies in accordance with the law. Lawful interception in the circuit domain generally adopts a network structure that conforms to the 3GPPETSI interception protocol. [0003] In the prior art, the monitoring function can usually be implemented through signaling interaction between a Lawful Interception Gateway (LIG for short) and a Network Element (NE for short). Specifically, the LIG receives the monitoring data and stores the monitoring data in a local database; the monitoring data can be used to set and control the monitored user. Then, the LIG sets the monitoring data to the NE, and the NE stores the monitoring data locally. Then, the NE can monitor the controlle...
