ABSTRACT:
When receiving an incoming call, a portable telephone that receives a search request judges whether or not this incoming call is the search request sent from a second portable telephone, which is a source of the search request. When the portable telephone judges that the incoming call is the search request sent from the second portable telephone, it is judged whether or not the receiving portable telephone is capable of determining its position information. When the portable telephone is incapable of determining its position information, the portable telephone automatically switches to a response hold state and transmits a search response message to the second portable telephone based on information stored in advance. Further, when the portable telephone is capable of determining its position information, the portable telephone determines its position information and transmits the position information to the portable telephone.
