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.
Claims42
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,
- wherein the period is changed based on a probability that a connection with said wireless LAN access point can be achieved, and the period is shortened when the probability increases and is lengthened when the probability decreases.
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,
- wherein said mobile communication terminal comprises:
- a determining section configured to receive specific signals transmitted from said first base station or said 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,
- wherein the period is changed based on a probability that a connection with said wireless LAN access point can be achieved, and the period is shortened when the probability increases and is lengthened when the probability decreases.
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),
- wherein the period is changed based on a probability that a connection with said wireless LAN access point can be achieved, and the period is shortened when the probability increases and is lengthened when the probability decreases.
A non-transitory recording 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),
- wherein the period is changed based on a probability that a connection with said wireless LAN access point can be achieved, and the period is shortened when the probability increases and is lengthened when the probability decreases.
