System and method for realizing signaling firewall based on signaling point-free access technology

Abstract

The invention discloses a system and a method for realizing a signaling firewall based on signaling point-free access technology. The system consists of message processor devices and a management server which access a signaling network; the message processor devices are serially connected in a signaling link which requires to perform gating and filtering on the signaling information in a signaling point-free encoding mode, execute the gating and filtering operation on the signaling information and realize the function of the signaling firewall when the signaling information flows through the devices; and the management server is responsible for the message gating and filtering rule management and equipment management of the message processor devices. The message processor devices can be unawarely serially connected in the signaling link of the signaling network accessed by the service processing signaling points without modification of the logical connection relationship of the service processing signaling points and the signaling network so as to realize the criterion transmission of the signaling information. Therefore, the aim of preventing abnormal signaling information from entering the signaling network is fulfilled, and the safe operation of the signaling network is guaranteed.

Description

technical field [0001] The present invention relates to a system and method for realizing a signaling firewall based on no signaling point access technology. By connecting a signaling message processing device in series with a signaling link of a signaling network connected to a service processing signaling point, In order to realize the standardized transmission of signaling messages, the purpose of preventing abnormal signaling messages from entering the signaling network is achieved, and the safe operation of the signaling network is guaranteed. Background technique [0002] In fixed and mobile communication networks, signaling is the key to service control. The signaling network is the core support network of the telecommunication network. Every telephone call and most new services are introduced without the support of the signaling network. [0003] The provision of services generally takes the service platform as a signaling point of the signaling network and connects ...

Problems solved by technology

[0003] The provision of services generally takes the service platform as a signaling point of the signaling network and connects it to the signaling network via a signaling link. Due to the diversity of service platforms and the importance of the signaling network, it is necessary A signaling firewall is set up between the signaling networks. This signaling firewall can work in the form of a signaling point. In the signaling working mode, it acts as a proxy device for signaling message communication between the service platform and the signaling network. The proxy device To realize the gating and filtering of signaling messages, based on the signaling point method, it is equivalent to adding a first-level signaling transfer function, and the firewall device access is complicated, requiring the cooperation of the service platform and the signaling network, which is poor in realizability
