Common line No. 7 between switching base stations Signal processing method of multiple stations

摘要

In the present invention, in order to increase the number of call lines as many as the number of local signal points in a method of allocating several local signal point codes in the same exchange country, a message is received from a user and the routing level is checked to check DOP data If it is impossible to use the DOP data from the state of the DOP data, the message is discarded and the message link cell for the DOP is found and the message is transmitted to the called point. Receiving a message from another station, obtaining an originating point according to a routing level, checking whether the received destination point belongs to n local stations, performing an STP function if it is not n local stations, and if it is n domestic stations, And checks the message type, the message of the signaling network management is sent to the signaling network management processor And the SCCP message carries the message with the SCCP looping function. Upon checking the type of the message, the message of the ISUP obtains the ISUPn for the MTPn, the CIC for the ISUPn ISUPn to forward the message.
