Signaling point-free access technology-based signaling firewall realization method

Abstract

The invention discloses a signaling point-free access technology-based signaling firewall realization method. Based on the method, a message processor device is connected in series with a signaling link of a signaling network connected with a service processing signaling point in the non-perception manner without modifying the logical connection relationship between the service processing signaling point and the signaling network. In this way, the standard transmission of signaling messages is realized. Therefore, abnormal signaling messages are prevented from entering the signaling network, so that the safe operation of the signaling network is ensured.

Description

technical field [0001] The present invention relates to a method for realizing a signaling firewall based on no signaling point access technology, by serially connecting a signaling message processing device in a signaling link of a signaling network connected to a service processing signaling point to realize The standardized transmission of signaling messages achieves the purpose of preventing abnormal signaling messages from entering the signaling network and guarantees the safe operation of the signaling network. 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 it to the signaling network via ...

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
