1. A method of controlling wireless communication between a master terminal and slave terminals, comprising;
- a) establishing a connection between the master terminal and a predetermined maximal number of the slave terminals to have active slave terminals;
b) identifying remaining unconnected slave terminals as inactive slave terminals in case a number of the slave terminals exceeds the predetermined maximal number;
c) 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;
d) repeating said step c) until every one of the slave terminals is at least once connected with the master terminal; and
e) communicating among the master terminal and the active slave terminals until a predetermined condition is met.

Abstract
Slave terminals and a master terminal are wirelessly connected according to the Bluetooth protocol. When a number of the slave terminals exceeds a predetermined number of the slave terminals for the wireless connection, the wireless connections are controlled by a predetermined set of rules. Active slave terminals are switched into inactive slave terminals according to the predetermined rules so as to efficiently use the resources in the system. The system is used for a data conferencing or class room instructions.

19. A system for controlling wireless communication, comprising;
-
a number of slave terminals; and
a master terminal for establishing a wireless connection between said master terminal and a predetermined maximal number of said slave terminals to have active slave terminals in accordance with the Bluetooth protocol, said master terminal identifying remaining unconnected ones of said slave terminals as inactive slave terminals in case the number of said slave terminals exceeds the predetermined maximal number, said master terminal removing one of said active slave terminals from the wireless connection to turn into one of said inactive slave terminals while establishing one of said inactive terminals for the wireless connection with said master terminal until every one of said slave terminals is at least once wirelessly connected with said master terminal, said master terminal communicating with said active slave terminals until a predetermined condition is met.

36. A master terminal for controlling wireless communication among a number of slave terminals, comprising;
-
a Bluetooth module for establishing a wireless connection between said master terminal and a predetermined maximal number of the slave terminals to have active slave terminals in accordance with the Bluetooth protocol; and
a CPU operationally connected to said Bluetooth module for identifying remaining unconnected ones of the slave terminals as inactive slave terminals in case the number of said slave terminals exceeds the predetermined maximal number, said CPU instructing said Bluetooth module to remove one of the active slave terminals from the wireless connection to turn into one of the inactive slave terminals while establishing one of the inactive terminals for the wireless connection with said master terminal until every one of the slave terminals is at least once wirelessly connected with said master terminal, said master terminal communicating with the active slave terminals until a predetermined condition is met.
