Abstract

A wireless unit 12 through a processing unit 16 communicate while forming an ad hoc network with other terminal apparatuses. A control unit 18 receives, when being assigned a role of approving participation of a new terminal apparatus in an ad hoc network, a participation request from a new terminal apparatus over a predetermined period after the execution of the role is requested and performs an approval process. The control unit 18 calculates the number of new terminal apparatuses at this time that have been approved. The control unit 18 gives notification of the result of calculation in addition to giving notification of the result of the approval process.

Claims

1. A terminal apparatus comprising:

a communication unit operative to communicate while forming an ad hoc network with other terminal apparatuses;

a reception unit operative, when being assigned a role of approving participation of a new terminal apparatus in an ad hoc network formed by the communication unit, to receive a participation request from a new terminal apparatus via the communication unit over a predetermined period after the execution of the role is requested by entering an approval mode;

a processing unit operative to perform an approval process on the participation request received by the reception unit; and

a notification unit operative to give notification of the result of the approval process performed by the processing unit, wherein

the processing unit extends the predetermined period when the processing unit approves a new terminal apparatus,

the processing unit calculates the number of new terminal apparatuses that have been approved in the predetermined period, compares a pre-set threshold value and a calculated number, and cancels the approval when the calculated number is larger than the pre-set threshold value, and

the communication unit participates in the ad hoc network and performs communication after the predetermined period.

2. A communication method comprising:

communicating while forming an ad hoc network with other terminal apparatuses;

receiving, when being assigned a role of approving participation of a new terminal apparatus in a formed ad hoc network, a participation request from a new terminal apparatus over a predetermined period after the execution of the role is requested by entering an approval mode;

performing an approval process on the received participation request; and

giving notification of the result of the performed approval process, wherein

in performing the approval process, the predetermined period is extended when a new terminal apparatus is approved,

in performing the approval process, the number of new terminal apparatuses that have been approved in the predetermined period is calculated, a pre-set threshold value and a calculated number are compared, and the approval is canceled when the calculated number is larger than the pre-set threshold value, and

the ad hoc network is participated in and communication is performed after the predetermined period.
