Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a block diagram of a short message according to the present invention is configured to switch to a mobile communication terminal is set up call transfer.

Referring to FIG. 1, a wireless communication service system to which the present invention is applied includes a base station 20, a mobile switching center (MSC) 30, a home location register (HLR) 40, and a short message service center. (SMSC, Short Message Service Center, 50) and a plurality of mobile communication terminals (10, 60, 70).

The base station 20 includes a transmission equipment necessary for network connection, a base station transceiver system (BTS) 21, and a base station controller (BSC) 22. These may be formed together in the same place or may be installed and operated in separate places. However, since the present invention does not need to be distinguished from each other, the base station 20 is called a block together.

The mobile switching center (MSC) 30 interfaces user calls from a wireless network to a wired network or other wireless networks. The mobile switching center (MSC) 30 may be connected with a plurality of base stations. A mobile switching center (MSC) 30 according to the present invention includes a first incoming mobile communication terminal in which an outgoing mobile communication terminal 10 performing an outgoing call to a mobile communication terminal of another party wants to receive a short message service (hereinafter referred to as SMS) ( 60, request the short message service center (SMSC) 50 to service a text message from the outgoing mobile terminal 10 to the first incoming mobile terminal 60.

The short message service center (SMSC) 50 provides a text service to a wireless mobile subscriber and generates various messages in response to a request signal from the mobile switching center (MSC) 30.

The home location register (HLR) 40 stores information about the assigned subscriber mobile terminals, including location information and service information, in its database (not shown).

The home location register 40 retrieves the location information and service information of the A mobile communication terminal to which the text message is to be received when the C mobile communication terminal wants to transmit a text message to the A mobile communication terminal. Thus, if the mobile terminal A is registered in the automatic switching of the short message service to the mobile terminal B, the mobile terminal is able to receive a text message transmitted from the mobile terminal C to the mobile terminal B.
