Abstract

Provided is a telephone switch such that an incoming call to an extension within the telephone switch can be picked up from a mobile terminal. The telephone switch includes: a receiving dial table which registers dial data that a mobile terminal uses to pick up an incoming call to a fixed-line telephone connected to the telephone switch; a conversion dial table which registers a call pick-up number used within the telephone switch for carrying out call pick-up of an incoming call to the fixed-line telephone; and a dial conversion unit configured such that when dial data sent by the mobile terminal is received when there is an incoming call to a fixed-line telephone, the dial conversion unit determines whether or not the received dial data sent from the mobile terminal matches the dial data in the receiving dial table, and if the dial data match, converts the received dial data to a call pick-up number in the conversion dial table such that the incoming call to the fixed-line telephone is picked up from the mobile terminal.

Claims (19)

1. A telephone switch connected to both of an extension for connecting devices included in a network on premises and an outside line for connecting devices through a network outside the premises, the telephone switch comprising:

a receiving dial table in which dial data to be used when picking up, from a mobile terminal, an incoming call to a fixed telephone set connected to the telephone switch via the extension is registered, the mobile terminal being connected to the telephone switch via the outside line;

a conversion dial table in which a call pick-up number to be used in the telephone switch when picking up an incoming call to the fixed telephone set is registered;

a dial conversion unit configured to, when dial data sent from the mobile terminal via the outside line is received when there is an incoming call to the fixed telephone set, determine whether the received dial data coincides with the dial data in the receiving dial table, and when both the dial data coincide with each other, and convert the received dial data to the call pick-up number in the conversion dial table; and

a call pick-up function unit configured to enable the mobile terminal to pick up, via the outside line, the incoming call to the fixed telephone set by using the call pick-up number for switching of the incoming call.

2. The telephone switch according to claim 1 , wherein the dial data registered in the receiving dial table uses a preset special service code.

3. The telephone switch according to claim 1 , wherein the call pick-up number uses a preset special service code.

4. The telephone switch according to claim 1 , wherein the mobile terminal conducts FMC (Fixed Mobile Convergence) linking with the telephone switch.

5. A telephone system comprising a telephone switch according to claim 1 , and the mobile terminal being connected to the telephone switch via an outside line, an incoming call in the telephone switch being picked up from the mobile terminal.

6. A call pick-up method in a telephone switch connected to both of an extension for connecting devices included in a network on premises and an outside line for connecting devices through a network outside the premises, the method comprising:

registering dial data to be used when picking up, from a mobile terminal, an incoming call to a fixed telephone set connected to the telephone switch via the extension, into a receiving dial table, the mobile terminal being connected to the telephone switch via the outside line;

registering a call pick-up number to be used in the telephone switch when picking up an incoming call to the fixed telephone set, into a conversion dial table;

in a dial conversion unit, when dial data sent from the mobile terminal via the outside line is received when there is an incoming call to the fixed telephone set, determining whether the received dial data coincides with the dial data in the receiving dial table, and when both the dial data coincide with each other, and converting the received dial data to the call pick-up number in the conversion dial table; and

in a call pick-up function unit, enabling the mobile terminal to pick up, via the outside line, the incoming call to the fixed telephone set by using the call pick-up number for switching of the incoming call.

7. A program for call pick-up in a telephone switch that causes a computer to function as a telephone switch, the computer being connected to both of an extension for connecting devices included in a network on premises and an outside line for connecting devices through a network outside the premises, the telephone switch comprising:

a receiving dial table in which dial data to be used when picking up, from a mobile terminal, an incoming call to a fixed telephone set connected to the telephone switch via the extension is registered, the mobile terminal being connected to the telephone switch via the outside line;

a conversion dial table in which a call pick-up number to be used in the telephone switch when picking up an incoming call to the fixed telephone set is registered;

a dial conversion unit configured to, when dial data sent from the mobile terminal via the outside line is received when there is an incoming call to the fixed telephone set, determine whether the received dial data coincides with the dial data in the receiving dial table, and when both the dial data coincide with each other, and convert the received dial data to the call pick-up number in the conversion dial table; and

a call pick-up function unit configured to enable the mobile terminal to pick up, via the outside line, the incoming call to the fixed telephone set by using the call pick-up number for switching of the incoming call.
