Abstract

A communication method includes the steps of: establishing a session with one or two or more other communication terminals according to a set content before it is changed in a case where a change request for own set information about a radio communication is received; notifying a set content to be changed to the one or two or more other communication terminals with which the session is established; and changing the own set information from the set content before it is changed to the set content to be changed.

Claims

1. A communication method performed by a communication terminal device, the method comprising:

establishing, by a control portion of the communication terminal device, a session with one or two or more other communication terminals according to a set content stored in a memory of the communication terminal device before it is changed in a case where a change request for own set information about a radio communication is received;

notifying, by a radio communication processing portion of the communication terminal device, a set content to be changed to the one or two or more other communication terminals with which the session is established;

changing, by the control portion, the own set information from the set content before it is changed to the set content to be changed;

returning, by the control portion, the own set information to the set content before it is changed in a case where a response is not received from at least one of all other communication terminals notified in the notifying before a predetermined period has elapsed since the changing; and

transmitting, by the radio communication processing portion, a message informing a success of a radio communication to all the other communication terminals in a case where responses are received from all the other communication terminals notified in the notifying before the predetermined time has elapsed since the changing, wherein

the set content to be changed and change timing thereof, and a waiting period for the message since the change timing has elapsed for returning the set information to the set content before it is changed in a case where the message is not received within the period, are notified in the notifying.

2. A communication method performed by a communication terminal device, the method comprising:

establishing, by a control portion of the communication terminal device, a session with one or two or more other communication terminals according to a set content stored in a memory of the communication terminal device before it is changed in a case where a change request for own set information about a radio communication is received;

notifying, by a radio communication processing portion of the communication terminal device, a set content to be changed to the one or two or more other communication terminals with which the session is established;

changing, by the control portion, the own set information from the set content before it is changed to the set content to be changed;

transmitting, by the radio communication processing portion in a case where a ratio of communication terminals from which responses are not received before the predetermined time has elapsed since the changing with respect to all the other communication terminals notified in the notifying is smaller than a threshold value, a message informing a success of a radio communication to the other communication terminals from which the responses are received, and presenting the other communication terminals from which the responses are not received or corresponding electronic devices to a user.

3. A communication terminal device comprising:

a memory that stores set information about a radio communication;

a radio communication processing portion; and

a control portion that controls the radio communication processing portion and the memory, wherein

the control portion establishes a session with one or two or more other communication terminals according to a set content before it is changed in a case where a change request for the set information is received and after a set content to be changed is notified to the one or two or more other communication terminals with which the session is established, changes the set information from the set content before it is changed to the set content to be changed,

the control portion returns the own set information to the set content before it is changed in a case where a response is not received from at least one of all other notified communication terminals before a predetermined period has elapsed since changing the set information,

the radio communication processing portion transmits a message informing a success of a radio communication to all the other communication terminals in a case where responses are received from all the other notified communication terminals before the predetermined time has elapsed since changing the set information, and

the set content to be changed and change timing thereof, and a waiting period for the message since the change timing has elapsed for returning the set information to the set content before it is changed in a case where the message is not received within the period, are notified in the notifying to the one or two or more other communication terminals.

4. A communication terminal device comprising:

a memory that stores set information about a radio communication;

a radio communication processing portion; and

a control portion that controls the radio communication processing portion and the memory, wherein

the control portion establishes a session with one or two or more other communication terminals according to a set content before it is changed in a case where a change request for the set information is received and after a set content to be changed is notified to the one or two or more other communication terminals with which the session is established, changes the set information from the set content before it is changed to the set content to be changed, and

the radio communication processing portion transmits, in a case where a ratio of communication terminals from which responses are not received before the predetermined time has elapsed since changing the set information with respect to all the other notified communication terminals is smaller than a threshold value, a message informing a success of a radio communication to the other communication terminals from which the responses are received, and presenting the other communication terminals from which the responses are not received or corresponding electronic devices to a user.
