Access method for communication terminal
First Claim
1. A communication terminal having a radio communicating function, the communication terminal comprising:
- a Global Positioning System (GPS) module that acquires positional information from a GPS satellite, indicating the position at which the communication terminal is present;
a controller which determines a range of correspondence information to be acquired, the range of correspondence information comprising a plurality of sections that are divided based on binarized values of latitude and longitude components of the positional information and a previously determined threshold, and each section corresponding to a frequency to be used at that respective section; and
,a receiver that acquires the correspondence information included in the range from a server,wherein the controller further identifies, based on the positional information acquired by the GPS module and the correspondence information included in the range acquired by the receiver, the frequency to be used between the communication terminal and a radio base station to be connected to the communication terminal.

Abstract
A communication terminal acquires positional information indicating the position at which the communication terminal exists, from a GPS satellite, determines a range of correspondence information to be acquired, from among the correspondence information that makes the positional information indicating position identified by latitude and longitude correspondent to the frequency to be used at that position and that is stored in a server, based on the acquired positional information, acquires the correspondence information included in the determined range, from the sever, and, identifies the frequency to be used between the communication terminal and the radio base station to be connected to the communication terminal, based on the acquired positional information and the correspondence information included in the range.
