MOBILE COMMUNICATION TERMINAL, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND CONTROL PROGRAM
First Claim
1. A mobile communication terminal which can communicate with a first base station, a second base station which is present within a service area of said first base station, and has a service area which is smaller than that of said first base station, and a wireless LAN access point, which is present within a service area of said second base station, said mobile communication terminal comprising:
- a determining section configured to receive a specific signal transmitted from said first or second base station and to determine whether or not there is a high possibility that said mobile communication terminal is connected to said wireless LAN access point, based on a reception result; and
a changing section configured to change a period to monitor arrival of a beacon signal transmitted from said wireless LAN access point based on the determination result of said determining section.

Abstract
A mobile communication terminal 10 receives “HCS_PRIO” of a notice data (System Information Block Type 3) of a base station 1 or 3, and determines whether the terminal 10 is present “indoor” and is in “a stationary state or a state moving at a low speed” based on the receiving result. Since there is a high possibility that the terminal 10 is connectable with a wireless LAN when the terminal 10 is present “indoor” and is in “a stationary state or a state moving at a low speed”, the terminal 10 sets a period for monitoring arrival of a beacon signal.

23. A communication method in a communication system comprising a mobile communication terminal which can communicate with a first base station, a second base station which is present within a service area of said first base station, and has a service area which is smaller than that of said first base station, and a wireless LAN access point, which is present within a service area of said second base station, said communication method comprising:
-
(A) receiving a specific signal transmitted from said first or second base station and determining whether or not there is a possibility that said mobile communication terminal is connected to a wireless LAN access point, based on the reception results; and (B) changing a period to monitor arrival of a beacon signal transmitted from said wireless LAN access point based on the determination result in said determination (A). - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A software medium stored with a computer-readable code for a control program for a communication method in a communication system comprising a mobile communication terminal which can communicate with a first base station, a second base station which is present within a service area of said first base station, and has a service area which is smaller than that of said first base station, and a wireless LAN access point, which is present within a service area of said second base station, said control program stored in said mobile communication terminal, and making a computer to execute:
-
(A) receiving a specific signal transmitted from said first or second base station and determining whether or not there is a possibility that said mobile communication terminal is connected to a wireless LAN access point, based on the reception results; and (B) changing a period to monitor arrival of a beacon signal transmitted from said wireless LAN access point based on the determination result in said determination (A). - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
