Make a call. Without this location information, the wireless zone in which the mobile terminal is located cannot be determined, and the mobile terminal switching center has no choice but to request the mobile terminal to call in the entire area. It is being done. A commonly used method for performing location registration is to send out a location registration signal on an outgoing control channel when it is detected based on incoming control channel information that a mobile terminal has moved from a control zone.
