Claim:
A mobile terminal registrable with a wireless communication network that comprises at least one communication area, comprising: a signal receiver configured to receive a first advertisement signal from the wireless communication network and a second advertisement signal from a mobile node; a first registration control responsive to the first advertisement signal to determine a communication area in which the mobile terminal is situated and register the mobile terminal as being independent in the wireless communication network, whereby the mobile terminal becomes locatable in connection with the determined communication area; a second registration control responsive to the second advertisement signal to reconfigure the mobile terminal as a subordinate to the mobile node, wherein the second registration control disables the first registration control and requests the mobile node to register the mobile node as being subordinate to the mobile node in the wireless communication network, whereby the mobile terminal becomes locatable in connection with a communication area in which the mobile node is situated; and a release control responsive to fading reception of the second advertisement signal to enable the first registration control and send a release request to cause the mobile terminal to be released from registration as being subordinate to the wireless node in the wireless communication network.
