MULTI-PARTY CALL SYSTEM AND METHOD FOR USING RADIO RESOURCES EFFICIENTLY

摘要

The present invention provides a multi-party call system and method for efficiently using radio resources. To this end, in the present invention, in constructing a multi-party call, mobile communication terminals capable of communicating in a Bluetooth communication scheme configure a Bluetooth network, and using only one mobile communication terminal as a gateway mobile communication terminal, Bluetooth communication is impossible. A GSM network using a GSM communication channel with another mobile communication terminal is constructed. Accordingly, the present invention reduces only the signaling load of the GSM network by requiring only GSM communication channels for connection between respective Bluetooth cells in a multi-party call, and efficiently saves radio resources of the GSM cell in the multi-party call. It can be used as an effect.;Multi-party call, Bluetooth communication, GSM communication
