Network intercommunication method

Abstract

The disclosed network intercommunication method makes two networks with identical network ID and different structures of signaling point possible to realize intercommunication without need of transfer through international network. The invention sets up second NI in exchange equipment. Structure of signaling point corresponding to the NI is identical to structure of network of opposite terminal. When receiving signaling from network of opposite terminal, the method converts first NI to second NI, and then carries out process. Before sending signaling to network of opposite terminal, the method converts second NI to first NI, and then sends it out. When user queries data of network of opposite terminal, exchange equipment converts second NI in queried result to first NI, and then outputs it out. After user configures data of opposite terminal, exchange equipment converts first NI in data to second NI and then saves it.

Description

technical field [0001] The invention relates to communication technology, in particular to the intercommunication of two communication networks across borders or regions. Background technique [0002] The No. 7 signaling protocol (Signalling System No.7, referred to as "SS7") is a common channel signaling protocol, which is used to control the control information instructions of call establishment and call routing processing on the telephone switching network. , fully redundant data network to control and manage voice and multimedia loops, and can quickly, non-blocking, and large-capacity transmission of signaling methods and signaling content for the control and management of telecommunication networks. Therefore, SS7 is currently a faster, more reliable, and more advanced signaling protocol. The SS7 signaling system can meet the requirements of various communication services, and its main applications are as follows: [0003] 1) Transmit the inter-network and inter-offic...

Problems solved by technology

[0010] In practical application, the above solution has the following problems: when the multinational operator requires the same device to be connected to the network of different countries, because there is no international network connection, the same network identification number but the same network identification number appear on the same device. The case where the signaling point structure is different

However, when two networks with different signaling point structures have the same network identifier, the switching device cannot determine the signaling point structure according to the network identifier, and thus cannot make the two networks communicate with each other.
