A mobile terminal detects a network formed on a communication media when the mobile terminal is to be connected to said communication media by transmitting control signals to and receiving control signals from the communication media and performs a connection control according to a protocol of a trunk network when the detected network is the trunk network or to a protocol of an ad hoc network when the detected network is the ad hoc network. When the mobile terminal can not detect a network to which the mobile terminal can be connected, the mobile terminal sets a new ad hoc network identifier for forming a new ad hoc network, after determining that the new ad hoc network identifier is not already in use another network.

[ What is claimed is:] [1.]1. A mobile terminal capable of being connected to either a trunk network provided with network connection nodes for connection of mobile terminals to said trunk network or an ad hoc network constructed by mutual connection of a plurality of mobile terminals, comprising:a network detection circuit for detecting whether or not there is a network on a communication media to which said mobile station can be connected when said mobile terminal is connected to said communication media;a trunk network connection circuit for controlling connection between said mobile terminal and said trunk network when said network detection circuit detects an existence of said trunk network;an ad hoc network connection circuit for controlling connection between said mobile terminal and said ad hoc network when said network detection circuit detects an existence of said ad hoc network, wherein said ad hoc network connection circuit comprises:a mobile terminal identifier candidate setting circuit for setting a candidate mobile terminal identifier for said mobile terminal predicted as being usable in a detected or newly formed ad hoc network;a mobile terminal identifier setting request message forming circuit for forming a mobile terminal identifier setting request message containing information related to the mobile terminal identifier set as the candidate;a broadcast message transmission circuit for performing a broadcast transmission of the formed mobile terminal identifier setting request message to the ad hoc network;an identifier setting circuit for setting the candidate mobile terminal identifier as the identifier of said mobile terminal when said mobile terminal receives no in-use mobile terminal identifier message indicating that the candidate mobile terminal identifier indicated in the mobile terminal identifier setting request is in use within a predetermined time from the transmission of the mobile terminal identifier setting request message; anda control circuit for activating said mobile terminal identifier candidate setting circuit and selecting another candidate, when said mobile terminal receives an in-use mobile terminal identifier message indicating that the candidate mobile terminal identifier indicated in the mobile terminal identifier setting request message is in use within the predetermined time from the transmission of the mobile terminal identifier setting request message; andan ad hoc network identifier setting circuit for setting a new ad hoc network identifier for forming an new ad hoc network when said network detection circuit detects no network on said communication media to which said mobile terminal can be connected.
