Embodiment Construction

[0022] Such as figure 2 As shown, the present invention, that is, the signaling message transfer device, is used for the transfer of signaling messages between signaling points of the No. 7 signaling system, including a sequentially connected signaling data link layer 1 and a signaling link function layer 2 and the signaling network functional layer 3, wherein: the signaling network functional layer 3 is further divided into a signaling message processing functional unit 31 and a signaling network management functional unit 32, and the signaling message processing functional unit 31 includes a message identification unit 311, A message distribution unit 312 , a message routing unit 313 and two network instruction conversion units 314 .

[0023] In order to keep the signaling message conforming to the No. 7 signaling protocol, each network instruction conversion unit 314 establishes a corresponding database 3141 between the logical network indicator and the original network in...

Abstract

This invention refers to a signaling message transfer device and method for transmitting / receiving message for transferring signaling message between signaling points of No 7 signaling system. Said invention leads the logic network concept in original No 7 signaling message process device, developing the definition of logic network indication language and process software, making one signaling point in No 7 signaling network support plurality of networks through combination of logic network indication language and signaling point coding, breaking the limit of there are only sixteen signaling links of adjacency signaling point and limited signaling point coding resource in current communication network to increase communication network capacity and loading ability.

Description

technical field [0001] The invention relates to the message transmission part of the No. 7 signaling system, in particular to a signaling message transmission device of the No. 7 signaling system message transmission part and a method for receiving / sending signaling messages. Background technique [0002] The No. 7 signaling system is an internationally standardized public channel signaling system, which realizes the functions of transmitting call control and communication routing control in the communication network. The No. 7 signaling system is divided into a message transfer part (MTP) and a service application part. The function of the message transfer part is to provide a common signaling transfer system to ensure that the signaling messages transferred between two switching nodes are error-free. Switching nodes are divided into signaling points (SPs) and signaling transfer points (STPs), which are collectively referred to as signaling points hereinafter. [0003] Suc...
