ABSTRACT:
The present invention reduces the number of location registration signals transmitted by slave terminals of gateway terminals forming ad hoc networks. Information on the current location of a gateway terminal is acquired. On the basis of the current location information acquired, a plurality of gateway terminals are grouped into a location registration area. Location registration area information indicative of the location registration area is transmitted to a mobile terminal mastered by the gateway terminal. The slave mobile terminal transmits a location registration signal only if the location registration area information has been changed. This makes it possible to reduce the number of location registration signals transmitted by the slave terminals compared to the case in which the gateway terminals are not grouped.
