Title:
PORTABLE TERMINAL, AND RADIO QUALITY DISPLAY METHOD, PROGRAM, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2006/001140
Kind Code:
A1
Abstract:
A portable terminal can obtain information on a place where the radio wave reception level is adequate from a second portable terminal irrespective of the radio wave reception level of the portable terminal. A portable terminal for communicating with a second portable terminal through a base station includes a communication interface for communicating with the second portable terminal not through the base station, a position detecting section, a radio wave reception level detecting section, a request transmitting section, an information receiving section, and an output section. The position detecting section detects the current position of the portable terminal. The radio wave reception level detecting section detects the radio wave reception level at the current position. A request transmitting section requests the second portable terminal to send the current position information and radio wave reception level of the second portable terminal through the communication interface. The information receiving section receives the current position information and radio wave reception level of the second portable terminal from the second portable terminal through the communication interface. The output section relates the current position and radio wave reception level of the portable terminal to those of the second portable terminal received by the information receiving section and outputs them.
