Embodiment Construction

[0040] In the following, the method and device for signalling protection between mobile communication networks of the present invention will be further described with reference to the accompanying drawings and specific implementations: in order to be able to identify and filter abnormal signalling from external mobile operator networks and actively defend against malicious access to external networks, The present invention provides a method and device for protecting signaling between mobile communication networks. The underlying access equipment is deployed between the external network STP and the internal network STP, and circuit-based or packet-based non-inductive access is adopted according to the mobile network's bearing mode. Method: The protection device logically deploys the back end of the underlying access device, has planning information of the protected network (including network element information and address planning), adopts different detection strategies according...

Abstract

The invention discloses a mobile communication internetwork signal prevention method and device. According to the method and the device, the defects of the mobile communication security prevention method and device in the prior art are overcome. The device comprises an external network and an internal network. The external network is a mobile network. The internal network is a target mobile network entity. A bottom layer processing device is connected between the interfaces of a signal transition point STP of the external network and a signal transition point STP of the internal network noninductively. A standard No.7 signal protocol is used between a bottom layer access device and the signal transition points of the internal network and the external network. The bottom layer access device receives signals and forwards to a device. The device is connected with a prevention device through a custom interface; an interface transmission layer applies a UDP protocol. An application layer applies a custom protocol. According to the method and the device, on the condition of not influencing the normal service of an operator, the signal messages initiated by the external mobile operator network are detected and processed, and malicious interference behaviors of the external network are prevented.

Description

Technical field [0001] The invention relates to mobile communication security protection technology, in particular to a method and device for protecting signaling between mobile communication networks. Background technique [0002] The Global Mobile Communications Network is an interconnected network. my country’s mobile operators have signed international roaming agreements with hundreds of mobile operators abroad. According to the roaming agreement, domestic and foreign mobile operators can access part of the user information of the other party through the international signaling network. However, the security mechanism of the 2G / 3G mobile signaling network is not perfect. The mobile network and users face interference from network elements and user sensitive information. Leak security threats. In addition, there are also various dedicated mobile communication networks in the country such as the military and party and government departments. Generally, proprietary core network...
