Call forwarding system and method for forwarding a call to a terminal through near-field wireless communication
View Patent ↗In a call forwarding system, a management apparatus of the call forwarding system determines service terminals capable of near field wireless communication within a reception range of near field wireless communication, generates a terminal list, and receives a call event message reporting the receipt of a call from a reference terminal. The management apparatus may transmit a call report message including the terminal list to the reference terminal and the service terminals. The management apparatus may forward the call initially received by the reference terminal to a terminal which transmitted a receipt request message by transmitting a call forwarding request message to the reference terminal. The management apparatus may transmit, to the reference terminal and the service terminals, a receipt report message reporting the call was forwarded. According to a change receipt message or upon non-receipt by an intended terminal, the call may be reforwarded to another terminal.
1. A method performed by a management apparatus to provide a call forwarding service, comprising:
receiving a call;
determining a plurality of service terminals capable of communicating with the management apparatus through a direct wireless communication;
generating a terminal list comprising information of the plurality of service terminals;
transmitting a call report message including the terminal list to the plurality of service terminals;
receiving a receipt request message from a first service terminal among the plurality of service terminals; and
forwarding the call to the first service terminal through the direct wireless communication.
2. The method of claim 1 , further comprising:
receiving a receipt designation message including information of a receipt commanding terminal and information of a call receiving terminal; and
transmitting to the plurality of service terminals transmitting a receipt designation report message including the information of the receipt commanding terminal and the information of the call receiving terminal.
3. The method of claim 1 , further comprising:
receiving a receipt change message from the first service terminal;
determining a changed call receiving terminal among the plurality of service terminals excluding the first service terminal; and
transmitting a change request message requesting a receipt of the call to the changed call receiving terminal.
4. The management apparatus of claim 1 , wherein
the control unit is further configured to:
receive a receipt designation message including information of a receipt commanding terminal and information of a call receiving terminal; and
transmit to the plurality of service terminals transmitting a receipt designation report message including the information of the receipt commanding terminal and the information of the call receiving terminal.
5. The management apparatus of claim 1 , wherein
the control unit is further configured to:
receive a receipt change message from the first service terminal;
determine a changed call receiving terminal among the plurality of service terminals excluding the first service terminal; and
transmit a change request message requesting a receipt of the call to the changed call receiving terminal.
6. A management apparatus to control a call forwarding service, comprising:
a direct wireless communication to transmit and receive a message including information of call forwarding to and from the management apparatus and a plurality of service terminals and to forward a call; and
a control unit configured to:
receive a call;
determine the plurality of service terminals capable of communicating with the management apparatus through a direct wireless communication;
generate a terminal list comprising information of the plurality of service terminals;
transmit a call report message including the terminal list to the plurality of service terminals;
receive a receipt request message from a first service terminal among the plurality of service terminals; and
forward the call to the first service terminal through the direct wireless communication.
