Abstract
A portable information terminal provided with a group terminal connection status management section which manages the connection statuses of a plurality of portable information terminals belonging to the same group connected by a tethering function; a host terminal order determination section which determines selection order of a portable information terminal to serve as a host terminal from among the portable information terminals belonging to the same group including its own terminal, based at least on reception quality from the base station, remaining battery capacity, and either a contracted allowable data transmission speed or a maximum data transmission speed notified from a network; and a control section which controls whether to operate as the host terminal or to communicate with the base station via the host terminal, based on the determined selection order.

16. A communication system constituted by a plurality of portable information terminals having a tethering function for operating as a host terminal which is connected to a base station using a first wireless communication and connects other portable information terminals to the base station using a second wireless communication, and a server connected to the base station, the server comprising:
-
a group terminal connection status management section which manages connection statuses of the plurality of portable information terminals belonging to the same group connected by the tethering function; a host terminal order determination section which determines selection order of a portable information terminal to serve as the host terminal from among the portable information terminals belonging to the same group including its own terminal and managed by the group terminal connection status management section, based at least on reception quality from the base station, remaining battery capacity, and either a contracted allowable data transmission speed or a maximum data transmission speed notified from a network; and a first control section which, when there is no portable information terminal operating as the host terminal, provides an instruction to a portable information terminal that can operate as the host terminal to serve as the host terminal, based on the selection order determined by the host terminal order determination section, and wherein the plurality of portable information terminals comprise; a second control section which controls to operate as a host terminal connected to the base station using the second wireless communication, according to the instruction from the server. - View Dependent Claims (17, 18)

19. A communication control method for a portable information terminal having a tethering function for operating as a host terminal which is connected to a base station using a first wireless communication and connects other portable information terminals to the base station using a second wireless communication, comprising:
-
a group terminal connection status management step of managing connection statuses of a plurality of portable information terminals belonging to the same group connected by the tethering function; a host terminal order determination step of determining selection order of a portable information terminal to serve as the host terminal from among the portable information terminals belonging to the same group including its own terminal, based at least on reception quality from the base station, remaining battery capacity, and either a contracted allowable data transmission speed or a maximum data transmission speed notified from a network; and a control step of controlling whether to operate as the host terminal or to communicate with the base station via the host terminal, based on the selection order determined in the host terminal order determination step.

20. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a processor in a portable information terminal having a tethering function for operating as a host terminal which is connected to a base station using a first wireless communication and connects other portable information terminals to the base station using a second wireless communication, the program being executable by the processor to actualize functions comprising:
-
a group terminal connection status management function for managing connection statuses of a plurality of portable information terminals belonging to the same group connected by the tethering function; a host terminal order determination function for determining selection order of a portable information terminal to serve as the host terminal from among the portable information terminals belonging to the same group including its own terminal, based at least on reception quality from the base station, remaining battery capacity, and either a contracted allowable data transmission speed or a maximum data transmission speed notified from a network; and a control function for controlling whether to operate as the host terminal or to communicate with the base station via the host terminal, based on the selection order determined by the host terminal order determination function.
