Abstract

The present invention is provided to implement an automated setting change of network setting items on an ad hoc network which does not have a specific base station. A method of changing network setting for changing setting of a network where a plurality of terminals are connected, the method including the steps of: a request source terminal transmitting a request for setting change to a selected representative terminal; the selected representative terminal, upon receiving the request for setting change, transmitting a request for permission to at least a majority of representative terminals; the selected representative terminal transmitting a success notification to the request source terminal upon receiving a notification of permission from the majority of representative terminals in response to the request for permission; the request source terminal transmitting, to the plurality of terminals, an execution instruction including at least a content of setting change, upon receiving the success notification; and the terminal which has received the execution instruction changing the setting according to the content of setting change.

First claim

What is claimed is:

1. A network setting changing method for changing a setting of a network in which a plurality of terminals are connected, the method comprising:
transmitting a setting change request from a request source terminal to a selected representative terminal, wherein the request source terminal is one of the plurality of terminals, the selected representative terminal selected from a plurality of representative terminals, the plurality of representative terminals selected from the plurality of terminals;
transmitting, upon receiving the setting change request, permission requests from the selected representative terminal to at least a majority of the plurality of representative terminals;
receiving, by the majority of the plurality of representative terminals, a permission request from the selected representative terminal;
transmitting a permission notification to the selected representative terminal in response to the permission request in a case where a permissible status flag is set at a time of receiving the permission request;
resetting the permissible status flag in the representative terminal, which has transmitted the permission notification, in response to the permission request;
transmitting from the representative terminal a non-permission notification instead of the permission notification in response to the permission request in a case where the permissible status flag is reset at the time of receiving the permission request;
transmitting a success notification from the selected representative terminal to the request source terminal upon receiving permission notifications from the majority of the plurality of representative terminals in response to the permission requests;
transmitting from the request source terminal to the plurality of terminals, execution instructions comprising at least a content of setting change, upon receiving the success notification; and
changing the setting according to the content of setting change in the plurality of terminals which have received the execution instructions,
wherein the permissible status flag indicates whether changing the setting of the network is permissible.

2. The network setting changing method according to claim 1 , further comprising transmitting a failure notification from the selected representative terminal to the request source terminal upon determining that the permission notifications are not receivable from the majority of representative terminals in response to the permission requests.

3. The network setting changing method according to claim 1 , further comprising setting the permissible status flag upon executing the change of setting in the representative terminal.

4. The network setting changing method according to claim 1 , further comprising:
transmitting cancel notifications from the selected representative terminal to the representative terminals to which the permission requests have been transmitted upon determining that the permission notifications are not receivable from the majority of representative terminals in response to the permission requests; and
setting the permissible status flags in the representative terminals upon receiving the cancel notifications.

5. The network setting changing method according to claim 1 , further comprising transmitting from the terminal which has received the execution instruction, upon determining that some inconvenience is to be caused by executing the setting change in accordance with the content of setting change, a setting change request in order to transmit execution instructions comprising a content of setting change corresponding to contents of setting neither before nor after setting change in accordance with the received execution instruction.

6. The network setting changing method according to claim 1 , further comprising transmitting from a plurality of the plurality of terminals, to other terminals of the plurality of terminals, information related to inconvenient setting,
wherein a terminal having received the success notification after receipt of the information related to inconvenient setting transmits the execution instruction comprising a content of setting change which makes the setting not the same as the inconvenient setting.

7. A network setting changing system for changing a setting of a network in which a plurality of terminals are connected, the system comprising
a request source terminal comprising means to transmit a setting change request to a selected representative terminal, wherein the request source terminal is one of the plurality of terminals, the selected representative terminal is selected from a plurality of representative terminals, and the plurality of representative terminals is selected from the plurality of terminals;
the selected representative terminal comprising means to, upon receiving the setting change request, transmit permission requests to at least a majority of the plurality of representative terminals;
the plurality of representative terminals comprising means to receive a permission request from a selected representative terminal;
the plurality of representative terminals comprising means to transmit a permission notification to the selected representative terminal in response to the permission request in a case where a permissible status flag is set at a time of receiving the setting change request;
the plurality of representative terminals comprising means to reset the permissible status flag upon transmitting the permission notification in response to the permission request;
the plurality of representative terminals comprising means to transmit a non-permission notification instead of the permission notification in response to the permission request in a case in which the permissible status flag is reset at the time of receiving the permission request;
the selected representative terminal comprising means to transmit a success notification to the request source terminal upon receiving permission notifications from the majority of the plurality of representative terminals in response to the permission requests;
the request source terminal comprising means to transmit, to the plurality of terminals, execution instructions comprising at least a content of setting change upon receiving the success notification, and
each of the plurality of terminals, which have received the execution instructions, comprising means to change the setting according to the content of setting change,
wherein the permissible status flag indicates whether changing the setting of the network is permissible.

8. A representative terminal, of a plurality of representative terminals, in a network setting changing system for changing a setting of a network in which a plurality of terminals are connected, wherein the representative terminal is one of a plurality of representative terminals, and the plurality of representative terminals are selected from the plurality of terminals, the representative terminal comprising:
means to receive a permission request from a selected representative terminal, the selected representative terminal selected from the plurality of representative terminals;
means to transmit a permission notification to the selected representative terminal in response to the permission request in a case in which a permissible status flag is set at a time of receiving the permission request;
means to reset the permissible status flag upon transmitting the permission notification in response to the permission request; and
means to transmit a non-permission notification instead of the permission notification in response to the permission request in a case in which the permissible status flag is reset at the time of receiving the permission request,
wherein the permissi
