Communication system with dialog board controller and its command transmitting method

Abstract

The invention is concerned with the transmitting signaling method with the conversation boundary controller in the communication system, it includes: the user equipment in the first network sends the signaling message of the login request to the signaling static transform function entity; after the signaling static transform function entity receives the signaling message, the signaling static transform function entity reworks the aiming IP address / port of the signaling message into the IP address / port of the signaling control function entity, reworks the source IP address / port into the IP address / port that the signaling static transform function entity assigns by itself, sends the signaling message to the signaling control function entity; the signaling control function entity processes analysis to the signaling message again and sends the signaling message to the function entity in the second network. The invention is also concerned with the communication system with the conversation boundary controller. The invention can avoid the baleful attack of the signaling control function entity in the conversation boundary controller, and the dispose of the conversation boundary controller is more agility and not limited by the group network of the actual network.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication network with a session border controller (SBC) and a signaling transmission method thereof. Background technique [0002] SBC is a concept proposed by the Internet Task Force (IETF) organization. It is called Session Border Controller (Session Border Controller) and is used to solve the border control problem of border session services in the next generation (NGN) network, such as access network and core The border control of the backbone network, the border control between the core backbone network and the core backbone network, or the border control between different management domains / address domains, is used to solve the intercommunication between different management domains and address domains, network security, and service Quality (QoS) control and other issues, such as the different address domains between different networks (access network, backbone...

AI Technical Summary

Problems solved by technology

[0016] In view of this, the object of the present invention is to provide a communication network with SBC and its signaling transmission method, so that the large-capacity centralized signaling control functional entity can shield the access user equipment, and reduce the number of signaling control functional entities. Potential safety hazards, while solving the above-mentioned problems that cannot be applied in actual networking
