A GPS portable terminal (2) carried by a person (1) monitors the position information of a dog (3) to which a GPS terminal (4) is attached. When the person (1) is separated from the dog (3) by a predetermined distance or more, the GPS portable terminal (2) carried by the person (1) issues a call request to portable terminals (6, 7, 8) of all guardians belonging to any one of a plurality of groups (A, B, C) including guardians by using PoC communication which allows intra-group communication like that performed by transceivers. When a response is received from a guardian group, communication can be performed within the group. This allows the guardian to guide the person (1) to a safe place.
