Abstract

A base station selecting method of this invention includes the steps of causing each of a plurality of ID transmitters (102) provided in the communication range of a wireless base station (103) to transmit location ID information for identifying the installation location of the ID transmitter (102) by a near field wireless communication scheme, and when a wireless terminal device (101) has received the location ID information, determining a connection destination wireless base station (103) based on the received location ID information. This makes it possible to speed up search processing and switch processing of the wireless base station (103) while suppressing an increase in the cost of the wireless terminal device (101) and also facilitate coverage design and coverage change of the wireless base station (103).

Claims

1. A base station selecting method comprising the steps of:

receiving location ID information transmitted, by a communication scheme different from that of a wireless base station, from each of a plurality of ID transmitters provided outside the wireless base station and in a communication range of the wireless base station, the location ID information containing information for identifying an installation location of each ID transmitter and base station information for specifying the wireless base station; and

determining, as a connection destination wireless base station, the wireless base station specified by the base station information contained in the received location ID information.

2. A wireless terminal device comprising:

a location ID receiving unit which receives location ID information transmitted, by a communication scheme different from that of a wireless base station, from each of a plurality of ID transmitters provided outside the wireless base station and in a communication range of the wireless base station, the location ID information containing information for identifying an installation location of each ID transmitter and base station information for specifying the wireless base station; and

a base station selection control unit which determines, as a connection destination wireless base station, the wireless base station specified by the base station information contained in the received location ID information.
