Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a dual-mode terminal according to the present invention.

As shown in FIG. 1, a dual mode terminal according to the present invention includes an antenna ANT, a duplexer 100, a CDMA module 110, a GSM module 120, and a controller 130.

The antenna ANT transmits and receives a radio signal, that is, a CDMA signal and a GSM signal, through a CDMA network and a GSM network. The duplexer 100 separates a radio signal received through the antenna ANT into a CDMA signal and a GSM signal and outputs the same to the CDMA module 110 and the GSM module 120. The duplexer 100 transmits the CDMA signal and the GSM signal output from the CDMA module 110 and the GSM module 120 through the antenna ANT.

The CDMA module 110 includes a CDMA transceiver 112 and a CDMA modem 114, the CDMA transceiver 112 demodulates the CDMA signal received from the duplexer 100 by the CDMA modem ( 114). The CDMA transceiver 112 modulates the CDMA data received from the CDMA modem unit 114 into a CDMA signal and transmits the same through the antenna ANT.

The CDMA modem unit 114 converts the CDMA signal demodulated by the CDMA transceiver 112 into digital data and transmits the converted digital data to the controller 130. The CDMA modem unit 114 converts the digital data output from the control unit 130 to the CDMA signal in analog form and outputs the same to the CDMA transceiver 112.

In addition, the GSM module 120 includes a GSM transceiver 122 and a GSM modem unit 124. The GSM transceiver 122 demodulates and outputs the GSM signal received through the antenna ANT to the GSM modem 124 and modulates the GSM data received from the GSM modem 124 into a GSM signal. And transmit on the frequency. The GSM modem unit 124 receives the output of the GSM transceiver 122 as an input, converts it into a digital signal, and outputs the digital signal. The GSM modem unit 124 receiving the digital signal of the controller 130 receives the digital signal. The signal is modulated into a GSM signal and output to the GSM transceiver 122.

The controller 130 performs communication by controlling the CDMA module 110 or the GSM module 120 according to a set communication mode (ie, a CDMA mode or a GSM mode), and uses another set communication mode while using the set communication mode. It plays a role of monitoring and notifying incoming call information. In this case, the incoming information includes the number of missed calls and new SMS messages. The controller 130 acquires and displays incoming information of another communication mode while the set communication mode maintains a sleep state. For example, when the CDMA module 110 enters a sleep state in the CDMA mode, the controller 130 switches the CDMA module 110 to an inactive state and activates the GSM module 120. In addition, the controller 130 accesses the GSM network through the GSM module 120 to obtain incoming information, and outputs the received incoming information so that a user can recognize it.

The dual mode terminal according to the present invention further includes an input unit 140 and a display unit 150. The input unit 140 is used to input a command for setting the communication mode and the monitoring function. The input unit 140 includes a numeric key and various function keys, and provides the controller 130 with information input by the user's key operation. In addition, the display unit 150 displays the obtained incoming call information under the control of the controller 130 and indicates the result and state according to the overall operation.

In addition, the dual mode terminal according to the present invention further includes a memory 160 for storing the setting information and the incoming information. The memory 160 stores various programs for performing overall operations of the dual mode terminal.

Thereafter, the controller 130 receives the incoming information transmitted from the connected CDMA network and informs the user.

Thereafter, the controller 130 checks whether the CDMA module 110 is in a sleep state (S106). If the CDMA module 110 is in the sleep state as a result of the check, the controller 130 checks whether a monitoring function for acquiring and informing the reception information received through another communication mode, that is, the GSM mode, is set (S108). Here, in the monitoring function setting, when the user selects the monitoring function setting menu, the control unit 130 displays the setting screen as shown in FIG. 3, and the user sets the monitoring function by operating the input unit 140. When the setting of the monitoring function is completed, the control unit 130 displays the communication mode (A) currently being used and the communication mode (B) being monitored on the display unit 150 as shown in FIG. do.

When the monitoring function is set as a result of the check, the controller 130 switches the CDMA module 110 to an inactive state and activates the GSM module 120. Under the control of the controller 130, the GSM module 120 scans a channel for communication with a GSM network and acquires a GSM system through the selected channel (S110, S112).

The controller 110 receives incoming information transmitted from the connected GSM network through the GSM module 120 and stores the received information in the memory 160 (S114).

Thereafter, the controller 130 returns to the original communication mode, that is, the CDMA communication mode (S116). At this time, under the control of the controller 130, the CDMA module 110 selects a communication channel through channel scanning and obtains a CDMA system through the selected communication channel.

When the CDMA module 110 wakes up from the sleep state after returning to the CDMA communication mode, the controller 130 displays the incoming information stored in the memory 160 as shown in FIG. 5. (S118).

In the present embodiment described above, the GSM communication mode is monitored while operating in the CDMA communication mode as an example. However, it is also possible to monitor the incoming information received in the CDMA communication mode while notifying the user by operating the GSM communication mode. Do.

As described above, the present invention monitors other communication modes and informs the user while using a specific communication mode, so that incoming call information received in another communication mode can be checked without changing modes, thereby providing convenience to the user.
