Abstract
The present invention relates to a point code emulation apparatus and method for dividing a Common Channel Signaling System No. 7 (or SS 7) signaling network into two or more networks. The point code emulator is adapted to receive TCAP messages from two or more subnets and converts, for the messages crossing over the subnets, the information of the TCAP messages, including originating point code, destination point code, and transaction identifier, (and optionally, calling party number and called party number), and forwards to the other one of the two or more subnets. Correspondence among the two or more subnets may be provisioned by an authorized user of the system, may be learned automatically by the system based on ISUP message correspondences or previous TCAP transactions, or may be automatically discovered by the system broadcasting messages to nodes in the destined one of the two or more subnets.
