Abstract

A mobile terminal includes a reception unit to receive, from at least one of a plurality of communication systems, an initial beacon containing information for establishing communication according to each of the plurality of communication methods, a request unit to generate a request by use of the initial beacon to transmit the request to the at least one of the plurality of communication systems, and a determination unit to determine, based on information as a response to the request, the communication method and the frequency band, which are to be used in a time zone by the mobile terminal.

Claims

1. A mobile terminal that performs wireless communication with one of a plurality of communication systems by using one of a plurality of communication methods, the one of the plurality of communication systems controlling the one of the plurality of communication methods, the mobile terminal comprising:

a reception unit to receive, from at least one of the plurality of communication systems, an initial beacon containing information for establishing communication according to each of the plurality of communication methods, the plurality of communication systems each controlling a corresponding one of the plurality of communication methods;

a request unit to use the information contained in the initial beacon to perform the communication with the at least one of the plurality of communication systems, to generate a provision request for information for determining a communication method and a frequency band, which are to be used in a time period by the mobile terminal, and to transmit the provision request to the at least one of the plurality of communication systems; and

a determination unit to receive information provided by the at least one of the plurality of communication systems in response to the provision request and to determine the communication method and the frequency band, which are to be used in the time period by the mobile terminal, based on the information provided and received from the at least one of the plurality of communication systems,

wherein the provided information contains, with regard to each communication method available for the mobile terminal, at least one of a measured value and a predicted value of each of usable frequency band information and operations, administration, and maintenance (OAM) information for the time period.

2. The mobile terminal according to claim 1, further comprising an acquisition unit to acquire information indicating a surrounding radio wave condition of the mobile terminal,

wherein the determination unit determines the communication method and the frequency band, which are to be used, based on the information indicating the surrounding radio wave condition.

3. The mobile terminal according to claim 1, further comprising an acquisition unit to acquire at least one of terminal status information containing a remaining battery charge of the mobile terminal and user action information containing a service content desired by a user of the mobile terminal and a scheduled use time period,

wherein the determination unit determines the communication method and the frequency band, which are to be used, based on the at least one of the terminal status information and the user action information, which are acquired by the acquisition unit.

4. The mobile terminal according to claim 1, further comprising a change unit to change the frequency band and an allowable radio wave strength, which are to be used for the wireless communication by the mobile terminal, according to the communication method and the frequency band, which are determined by the determination unit.

5. A method of determining a communication method and a frequency band, which is used for a mobile terminal that performs wireless communication with one of a plurality of communication systems by using one of a plurality of communication methods, the one of the plurality of communication systems controlling the one of the plurality of communication methods, the method comprising:

receiving, from at least one of the plurality of communication systems, an initial beacon containing information for establishing communication according to each of the plurality of communication methods, the plurality of communication systems each controlling a corresponding one of the plurality of communication methods;

using the information contained in the initial beacon to perform the communication with the at least one of the plurality of communication systems, generating a provision request for information for determining a communication method and a frequency band, which are to be used in a time period by the mobile terminal, and transmitting the provision request to the at least one of the plurality of communication systems;

receiving information provided by the at least one of the plurality of communication systems in response to the provision request; and

determining the communication method and the frequency band, which are to be used in the time period by the mobile terminal, based on the information provided and received from the at least one of the plurality of communication systems,

wherein the provided information contains, with regard to each communication method available for the mobile terminal, at least one of a measured value and a predicted value of each of usable frequency band information and operations, administration, and maintenance (OAM) information for the time period.

6. A computer readable medium for storing a program executed by a mobile terminal that performs wireless communication with one of a plurality of communication systems by using one of a plurality of communication methods, the one of the plurality of communication systems controlling the one of the plurality of communication methods, the program causing the mobile terminal to execute:

receiving, from at least one of the plurality of communication systems, an initial beacon containing information for establishing communication according to each of the plurality of communication methods, the plurality of communication systems each controlling a corresponding one of the plurality of communication methods;

using the information contained in the initial beacon to perform the communication with the at least one of the plurality of communication systems, generating a provision request for information for determining a communication method and a frequency band, which are to be used in a time period by the mobile terminal, and transmitting the provision request to the at least one of the plurality of communication systems;

receiving information provided by the at least one of the plurality of communication systems in response to the provision request; and

determining the communication method and the frequency band, which are to be used in the time period by the mobile terminal, based on the information provided and received from the at least one of the plurality of communication systems,

wherein the provided information contains, with regard to each communication method available for the mobile terminal, at least one of a measured value and a predicted value of each of usable frequency band information and operations, administration, and maintenance (OAM) information for the time period.
