Abstract

A computer performs a control including (1) receiving a request for monitoring a station to-be-handled which is a communication apparatus different from a pertinent station including the computer, (2) transmitting a request for a response based on the station to-be-handled, to the station to-be-handled at a predetermined time interval, on the basis of the monitoring request, and (3) transmitting a message expressing that the station to-be-handled will be detached from a network, to the network if the response to the response request was not received within a predetermined wait time.

Claims

1. A recording medium bearing a program which causes a computer to perform a control comprising:

receiving a request for monitoring a station to-be-handled which is a communication apparatus different from a pertinent station including the computer;

transmitting a request for a response based on the station to-be-handled, to the station to-be-handled at a predetermined time interval, on the basis of the monitoring request; and

transmitting a message expressing that the station to-be-handled will be detached from a network to the network if the response to the response request was not received within a predetermined wait time.

2. A recording medium bearing a program which causes a computer to perform a control as defined in claim 1, further comprising:

acquiring aptitude information which is information expressing an aptitude to the monitoring based on the pertinent station, before receiving the request.

3. A recording medium bearing a program which causes a computer to perform a control as defined in claim 1, wherein:

receiving the request for monitoring the station to-be-handled which is the communication apparatus different from the pertinent station comprises further receiving an aptitude information of another station, the another communication apparatus being different from the pertinent station.

4. A recording medium bearing a program which causes a computer to perform a control as defined in claim 2, wherein:

the aptitude information of the pertinent station is transmitted to the other station if the request for the aptitude information has been received from the other station, the other communication apparatus being different from the pertinent station.

5. A recording medium bearing a program which causes a computer to perform a control as defined in claim 2, wherein:

the aptitude information of the communication apparatus contains at least one member selected from the group consisting of a power supply for driving the communication apparatus, a remaining capacity of a battery for driving the communication apparatus, a network interface of the communication apparatus, a radio wave intensity received or transmitted by the communication apparatus, a processing capability of the communication apparatus, and a storage capacity of the communication apparatus.

6. A recording medium bearing a program which causes a computer to perform a control as defined in claim 2, further comprising:

deciding whether or not the pertinent station is qualified for the monitoring, on the basis of the aptitude information of the pertinent station and the aptitude information of the other station, before the first acquiring aptitude information and receiving the request;

wherein the first transmitting is executed if it has been decided by the deciding that the pertinent station is qualified for the monitoring.

7. A communication apparatus which is connectable to a network, comprising:

a reception portion which receives a request for monitoring a station to-be-handled being a communication apparatus that is different from a pertinent station being the connectable communication apparatus;

a first transmission portion which transmits a request for a response based on the station to-be-handled, to the station to-be-handled at a predetermined time interval, on the basis of the monitoring request; and

a second transmission portion which transmits a message expressing that the station to-be-handled will be detached from the network, to the network if the response to the response request was not received within a predetermined wait time.

8. A communication apparatus as defined in claim 17, further comprising:

a first acquisition portion which acquires aptitude information being information that expresses an aptitude to the monitoring based on the pertinent station.

9. A control method in which a computer performs a control comprising:

receiving a request for monitoring a station to-be-handled which is a communication apparatus different from a pertinent station including the computer;

transmitting a request for a response based on the station to-be-handled, to the station to-be-handled at a predetermined time interval, on the basis of the monitoring request; and

transmitting a message expressing that the station to-be-handled will be detached from a network, to the network if the response to the response request was not received within a predetermined wait time.

10. A control method in which a computer performs a control as defined in claim 9, further comprising:

acquiring aptitude information which is information expressing an aptitude to the monitoring based on the pertinent station, before receiving the request.
