[0042] Hereinafter, the present invention will be specifically described by taking the authentication registration of the SCDMA (Synchronous Code Division Multiple Access System) system as an example.
[0043] In SCDMA system, VDT (relay management unit) is used as a unit to add virtual relay in switching equipment, and each VDT contains 4 E1s. Assign the added virtual trunk to the trunk group, and assign the trunk group to the route. These operations are the same as the real trunk. In addition, it is necessary to ensure that there is a direct No.7 signaling link or a No.7 signaling link connected through a signaling transfer point between the two LMCCs connected by the virtual trunk, and there is a corresponding virtual center on the two LMCCs. Relay data (one-to-one correspondence between CIC codes of virtual relays).
[0044] In the process of business processing, according to the message type, it is determined whether the selected trunk circuit is a virtual trunk or a rea...
