Abstract
Disclosed are a mobile communication terminal for and a method of transmitting/receiving voice messages using a packet-switched scheme. According to the present invention, it is possible to allow mobile carriers to promote the use efficiency of communication channels since mobile communication terminals transmit/receive voice messages over a data channel rather than a voice channel.
Claims14
A mobile communication terminal, comprising:
- a communication unit configured to transmit/receive data signals over a mobile communication network;
- a communication controller configured to control communication setup and termination in response to a signal inputted from the outside, wherein the communication controller includes
- automatic voice channel releasing means for automatically terminating a voice channel connection upon receiving a connection failure signal from the communication unit, and
- automatic data channel connection means for outputting a data channel connection request signal upon receiving the connection failure signal from the communication unit;
- and
- a packet processor configured to packetize voice data inputted from the outside and outputting the packetized voice data to the communication unit in response to a control signal of the communication controller.

A voice message transmission system, comprising:
- a mobile communication terminal configured to transmit/receive a voice message using a packet-switched scheme, wherein the mobile communication terminal includes
- a communication unit configured to transmit/receive data signals over a mobile communication network;
- a communication controller configured to control communication setup and termination in response to a signal inputted from the outside, wherein the communication controller includes
- automatic voice channel releasing means for automatically terminating a voice channel connection upon receiving a connection failure signal from the communication unit, and
- automatic data channel connection means for outputting a data channel connection request signal upon receiving the connection failure signal from the communication unit, and
- a packet processor configured to packetize voice data inputted from the outside and outputting the packetized voice data to the communication unit in response to a control signal of the communication controller;
- a mobile switching center configured to perform a switching operation for a packetized voice message transmitted/received to/from the mobile communication terminal;
- and
- a voice mail unit which includes a packet control unit configured to receive the packetized voice message from the mobile switching center and to store the packetized voice message in a voice message database on a packet-by-packet basis.
