The present invention relates to a communication control method of a mobile communication terminal, and more particularly, in a hybrid mode mobile communication terminal supporting EVDO and SVD, data communication and voice communication according to a new method of changing from an SVD service to a 1x channel. The present invention relates to a mobile communication terminal and a method for simultaneously providing the same.

In modern society, mobile communication terminals are widely used as a necessity for modern people as a means of convenient communication without regard to place. Recently, as the performance of the processor is improved and the resources of the memory are increased, the mobile communication terminal provides various functions as well as the conventional mobile communication service.

Recently, various multimedia services such as video download, VOD service, music file download, photo shooting and storage have been used by mobile communication terminals. Accordingly, a situation often arises in which a call is made or a call is made while using the service. In addition, a situation arises in which a data transmission / reception service is used during a phone call with a counterpart.

However, when the mobile communication terminal using the EVDO-1x service receives the paging for the voice call while connected to the EVDO call and uses the service, the mobile communication terminal stops the EVDO call in use and receives the voice call. That is, when the user connects the EVDO-1x service supporting terminal with the EVDO call in the EVDO and 1x overlay areas and receives voice call paging, the user transitions to the 1x system channel in the currently used EVDO system channel for voice call. 1x Voice call is placed in the waiting state. Also, the EVDO call automatically goes to dormant state.

As a result, the conventional mobile communication terminal unconditionally stops the EVDO call in use and receives the voice call, and there is a problem that the EVDO service cannot be used without distinguishing the importance between the EVDO service and the voice call. In addition, since the EVDO service cannot be used even when data communication is performed using the EVDO service during voice communication, the user has to select only one of the two services.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art as described above, and an object of the present invention is to enable a user to use voice call communication using a 1x channel during EVDO data communication to a mobile communication terminal. It is to provide a communication method of the communication terminal.

Another object of the present invention is to provide a communication method of a mobile communication terminal that enables a user to perform data communication using a 1x channel during voice call communication with a mobile communication terminal.

It is still another object of the present invention to provide a mobile communication terminal capable of simultaneously using EVDO data communication and voice call communication using a 1x channel.

The communication control method of the mobile communication terminal according to the present invention for achieving the object of the present invention as described above and to solve the above-mentioned problems of the prior art, performing the EVDO service through the EVDO channel and SVD (through the 1x channel) Simultaneous Voice and Data) service, characterized in that the data communication and voice communication is performed at the same time by disconnecting the EVDO channel to the 1x channel in the SVD service.

According to another aspect of the present invention, there is provided a mobile communication terminal including an EVDO processor supporting an EVDO service through an EVDO channel and an SVD processor supporting an SVD service through a 1x channel. For the SVD service, the EVDO channel is disconnected and changed to the 1x channel so that data communication and voice communication are simultaneously performed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings and the contents described in the accompanying drawings, but the present invention is not limited or limited to the embodiments. Like reference numerals in the drawings denote like elements.

Hereinafter, embodiments of a mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an operation of a mobile communication terminal according to an embodiment of the present invention.

First, the mobile communication terminal receives an instruction from the user as to whether to use the EVDO data service or the voice communication service by accessing the EVDO system in the power-on state (S110) (S120). That is, in step S110, the mobile communication terminal is selected to use the data service or voice communication by accessing the EVDO communication network.

The EVDO (EVolution Data Only) is a standard of wireless access technology optimized for high speed and high capacity data transmission and refers to a technology that has been advanced one step from CDMA2000 1x. It adopts Single Carrier method, and many subscribers are high-speed data service at low cost by using the maximum data rate and the capacity improved than CDMA2000 1x several times more than the maximum data rate of CDMA2000 1x forward channel. The EVDO can provide rich multimedia contents in more diverse fields such as wireless Internet access, real-time traffic information, wireless live broadcasting, TV, movies, music videos, internet games, M-Commerce, etc. due to the improved data transmission speed and capacity. have.

When performing data communication using the mobile communication terminal, the EVDO data service is activated (or in use) (S121). The voice call may be used to request a phone call from another mobile communication terminal or to make a phone call to another mobile communication terminal while the mobile communication terminal performs data communication. Since the mobile communication terminal uses an EVDO data service, the mobile communication terminal changes the EVDO channel to a 1x channel (S123). Therefore, the mobile communication terminal is in the EVDO data service is dormant (dormant) state and provides voice communication using the 1x channel.

In this case, for data communication while providing voice communication, the voice call may be first checked whether there is a voice call while using an EVDO data service, and then forced to use a 1x channel. You can also force dormant handoffs to the 1x channel when you disconnect the EVDO channel to use voice calls (called or incoming). When the voice call is terminated in the above manner, the mobile communication terminal may simultaneously terminate 1x data traffic so that the EVDO system may be automatically used when re-sending.

In addition, the mobile communication terminal may be designed to avoid the EVDO system as a method for disconnecting the EVDO channel. In this case, the mobile communication terminal may set a timer to avoid the EVDO system when the EVDO channel is disconnected by the voice call. Therefore, when the voice call is terminated according to the timer, the mobile communication terminal may be controlled to use the EVDO system again when the timer is finished.

Therefore, it is possible to implement an SVD service capable of simultaneously serving data communication and voice communication. In addition, the SVD service is a form of using a dedicated line, which means that a voice-class line is divided by frequency division, time division, or the like to simultaneously transmit voice and data (including telegraph and fax).

Alternatively, if the voice communication is to be performed using the mobile communication terminal, the EVDO data service becomes a dormant (S131). In this case, when the mobile communication terminal attempts to transmit and receive data to another mobile communication terminal, the mobile communication terminal may use the data service by cutting off the EVDO channel and changing to 1x channel during voice communication (S133). In the above manner, when the mobile communication terminal terminates the voice call, the 1x data traffic may be terminated at the same time so that the EVDO system may be automatically used when the redial call is made.

In this case, for data communication while providing voice communication according to the voice call processing, the mobile communication terminal may first check whether an existing voice call exists before using the data service, and then force the use of the 1x channel. . By the voice call, the EVDO channel may be dormant handoff to a 1x channel. In addition, the mobile communication terminal may set a timer to avoid the EVDO system by the voice call. That is, the timer is a timer for avoiding the EVDO system when the voice call ends, and may be controlled to use the EVDO system again when the timer is finished.

Accordingly, the user can perform voice communication during data communication using the EVDO service so that the user can make a phone call while downloading data or transmitting data from another terminal, and make a data communication service while making a phone call with another user. Can be used to receive data from another terminal during voice communication.

2 is a diagram for describing an operation relationship between an EVDO service 210 and an SVD service 220 according to an embodiment of the present invention.

The EVDO service 210 is a high-speed data service that can be used simultaneously by a plurality of subscribers, and may be particularly useful for providing multimedia content. A user uses the EVDO service for data communication in the mobile communication terminal (active state). If the mobile communication terminal wants to receive or make a voice call while using the EVDO service, the current EVDO channel is changed to a 1x channel. Therefore, the mobile communication terminal is in the EVDO data service is dormant (dormant) state and provides voice communication using the 1x channel. That is, switching to the SVD service 220 using the 1x channel.

As described above, while using the EVDO data service to provide the voice communication, the voice call may be first checked and then forced to use the 1x channel, and the forced 1x channel when the EVDO channel is disconnected. Dormant handoff can be done. While using the SVD service 220 as above, the EVDO protocol may continue to monitor the EVDO channel.

In addition, the mobile communication terminal may be designed to avoid the EVDO system as a method for disconnecting the EVDO channel, and a timer may be set to avoid the EVDO system. This method has an advantage that the EVDO protocol is deactivated during the SVD service 210 so that the power of the mobile communication terminal can be used more efficiently.

Therefore, the SVD service can implement a service that can simultaneously transmit voice and data by a method such as frequency division.

In addition, as described above, when the voice communication is used in the mobile communication terminal, the EVDO data service 210 is in a dormant state and is transferred to another mobile communication terminal during voice communication in the mobile communication terminal. When trying to transmit and receive data, the SVD service 220 supporting the data service is used by cutting off the EVDO channel and changing to 1x channel during voice communication.

The communication control method of the mobile communication terminal according to the present invention can be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. The computer readable medium may include program instructions, data files, data structures, etc. alone or in combination.

The medium may be a transmission medium such as an optical or metal wire, a waveguide, or the like including a carrier wave for transmitting a signal specifying a program command, a data structure, or the like. Examples of program instructions include not only machine code generated by a compiler, but also high-level language code that can be executed by a computer using an interpreter or the like. The hardware device described above may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.
