Location registration method for mobile communication terminals, en bloc paging method for mobile communication terminals, and mobile communication system

A mobile proxy device registrable in 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 determine, based on the received first advertisement signal, a communication area in which the proxy device is situated;
• a terminal probe configured to transmit a second advertisement signal to find if there is a mobile terminal responding to the second advertisement signal;
• a registration control configured to register, in the wireless communication network, the proxy device, along with the found mobile terminal as being subordinate to the proxy device, whereby the proxy device and the mobile terminal become locatable in connection with the determined communication area;
• and
• a downstream message control configured to receive a message from the wireless communication network which is directed to a plurality of mobile terminals subordinate to the proxy device and deliver sub-messages created based on the message to the plurality of subordinate mobile terminals, respectively.

A wireless communication network comprised of at least one communication area, comprising:

• a receiver configured to receive a registration request that identifies a communication area and a group of mobile nodes bound by a set of superior/subordinate relations;
• a registration request control configured to store in a memory identifications of the group of mobile nodes in connection with the communication area and their superior/subordinate relations;
• a paging request control configured to receive paging requests identifying mobile nodes in the group and search the memory to determine a communication area stored in the memory in connection with the mobile nodes identified by the paging requests;
• and
• a paging message control configured to compose one collective paging message addressed to the mobile nodes identified by the paging requests and cause the collective paging message to be sent out to the determined communication area.
