Communication terminal and program using a packet switched communication line and a circuit switched communication line
View Patent ↗To enable a user of a communication terminal to note that the terminal has received data by data communication conducted in the background of a voice communication, easily and in the required time. After establishing a voice communication line between mobile phone 100 - 2, mobile phone 100 - 1 establishes a data communication line with mobile phone 100 - 2 and acquires image data. When disconnecting a voice communication line, mobile phone 100 - 1 produces a notification sound and displays the acquired image data, thereby notifying a user of mobile phone 100 - 1 of acquiring data by data communication during voice communication.
1. A communication terminal for performing at least partly simultaneous voice communication and data communication with a correspondent terminal, comprising:
a first communication controller that establishes a circuit-switching communication line to the correspondent node;
a second communication controller that establishes a packet-switching communication line to the correspondent node, wherein the communication terminal uses packet-switching communication via the packet-switching communication line at least partly concurrently with communicating via the circuit-switching communication line;
data sending-receiving unit that sends and receives data using the packet-switching communication line established by the second communication controller; and
notifying unit configured to notify that the data sending-receiving unit has received data while performing the circuit-switching communication,
wherein the second communication controller establishes the packet-switching communication by:
sending a connection request message to a gateway apparatus, the connection request message including subscriber information of the correspondent node,
receiving a connection response message from the gateway apparatus, the connection response message including a data communication address of the correspondent node, and
establishing the packet communication line dedicated to data communication to the correspondent node.
2. A communication terminal for performing at least partly simultaneous voice communication and data communication with a correspondent terminal, comprising:
a first communication controller that establishes a circuit-switching communication line to the correspondent node;

data sending-receiving unit that sends and receives data using the packet-switching communication line established by the second communication controller; and
notifying unit configured to notify that said data sending-receiving unit has received data while performing the circuit-switching communication,
wherein the second communication controller establishes the packet-switching communication by:
sending a connection request message to a gateway apparatus, the connection request message including subscriber information of the correspondent node,
receiving a connection response message from the gateway apparatus, the connection response message including a data communication address of the correspondent node, and
establishing the packet communication line dedicated to data communication to the correspondent node.

14. A computer-readable medium storing a program for causing a computer to provide the functions of:
establishing a circuit-switching communication via a first communication line in order to communicate to a correspondent node;
establishing a second communication line with the correspondent node in order to communicate via a packet-switching communication with the correspondent node, wherein the packet-switching communication via the second communication line is at least partly concurrent with the circuit-switching communication via the first communication line;
sending and receiving data using the packet-switching communication via the second communication line; and
notifying that said data has been received during the circuit-switching communication via the first communication line,
wherein the packet-switching communication is established by:
sending a connection request message to a gateway apparatus, the connection request message including subscriber information of the correspondent node,
receiving a connection response message from the gateway apparatus, the connection response message including a data communication address of the correspondent node, and
establishing the packet communication line dedicated to data communication to the correspondent node.
