Message), if asynchronous, sends an International Mobile Subscriber Identify (IMSI) message to the exchange over the wireless network, and the exchange compares all MIN or IMSI via the MIN and ESN messages or IMSI messages sent to the subscriber. After determining whether it is a home subscriber or a visiting subscriber of the exchange, the subscriber requests a profile of the subscriber to a home location register (HLR). If the terminal subscriber is a visiting subscriber, the home exchange, for example, a STP (Signaling Transfer Point) To the home location register to which the subscriber of the terminal belongs by using the routing information stored in the And it transmits the message.
