Patent ID: 7526253

Claim:
A method of controlling wireless communication between a master terminal and slave terminals, a connection being established between the master terminal and a predetermined maximal number of the slave terminals to have active slave terminals, remaining unconnected slave terminals being identified as inactive slave terminals in case a number of the slave terminals exceeds the predetermined maximal number, comprising the steps of; a) removing one of the active slave terminals from the connection to turn into an inactive slave terminal while establishing one of the inactive terminals for the connection with the master terminal in case the number of the slave terminals exceeds the predetermined maximal number; b) communicating among the master terminal and the active slave terminals; c) determining an amount of data communication between the master terminal and the active slave terminals; d) comparing the data communication amount to a predetermined data communication amount to generate a data comparison result; and e) based upon the data comparison result, removing one of the active slave terminals from the connection to turn into an inactive slave terminal while establishing one of the inactive terminals for the connection with the master terminal to turn into an active slave terminal.
