Method, device and system of data interception

Abstract

Provided are a data interception method, device and system. The method includes: an interception management network element receiving a call relevant message reported by at least one managed network element in an IMS respectively, each call relevant message carrying a charging identifier of a corresponding call thereof respectively; the interception management network element combining each call relevant message according to the charging identifier; and the interception management network element reporting the combined call relevant message to an LIG, and the LIG intercepting the combined call relevant message. The device includes a first receiving module, a first combination module and a reporting module. The system includes a lawful interception gateway (LIG), an interception management network element and at least one managed network element. The interception management network element includes the abovementioned data interception device. As compared to the prior art, the embodiments of the present invention will not increase additional adaptation and modification workload, reducing the maintenance difficulty of the interception system and simplifying the interception implementation.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a data monitoring method, device and system. Background technique [0002] Lawful interception refers to the national security agency's monitoring of a user's communication process in accordance with the law. The content of the monitoring includes signaling and media-level data. figure 1 It is a schematic diagram of the structural relationship of monitoring functional entities in the prior art, such as figure 1 As shown, the lawful interception in the circuit domain generally adopts a network structure conforming to the interception protocol of The 3rd Generation Partner Project (hereinafter referred to as: 3GPP) and the European Telecommunications Standards Institute (hereinafter referred to as: ETSI). A Lawful Interception Gateway (hereinafter referred to as: LIG) may include a law enforcement monitoring facility (Law Enforcement Monitoring Facility; ...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing technology, whenever a new monitoring service is derived, LIG ​​needs to be adapted and modified, which increases the difficulty of maintaining the entire system, and the implementation of monitoring is not convenient enough.
