Patent ID: 8762557

Claim:
A method for a signaling gateway (SG) to process a signaling, comprising: configuring a Signaling Connection Control Part (SCCP) protocol, one or more SCCP service related subsystems, and Global Title (GT) translation function in the SG, and configuring a signaling point code of the SG to be the same as the signaling point code of a Media Gateway Controller (MGC), wherein the SG and the MGC are connected in a Message Transfer Part layer 3 (MTP3) User Adaptation layer (M3UA) protocol, and the MGC is configured with one or more SCCP service related subsystems; the SG receiving a connectionless-oriented SCCP service message through the MTP3 protocol; the SG determining whether the message is a local node message according to a destination signaling point code carried in the message or a signaling point code generated by translating a GT carried in the message; and if the message is a local node message, the SG, according to a subsystem number carried in the message, forwarding the message to a corresponding SCCP service related subsystem configured in the SG or forwarding the message to a corresponding SCCP service related subsystem configured in the MGC through the M3UA protocol.
