Abstract

PROBLEM TO BE SOLVED: To enable voice communication and data communication to be executed simultaneously using single terminal equipment. SOLUTION: If the data communication occurs during the voice communication by a radio unit 11 of a PDC, a voice/data-switching controller 26 controls a PDC/PHS-switching controller 25, and originates via a PHS radio unit 12. Conversely, if data communication is made during the voice communication due the PHS radio unit 12, the controller 26 controls the controller 25, to enable the radio unit 11 of the PDC to be originated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal in a portable telephone system, and more particularly, to a PDC (Personal D).
digital Cellular) and PHS (Personal Handyphone Sys)
The present invention relates to a communication method in a mobile communication terminal capable of performing communication by a plurality of wireless communication schemes, such as a composite terminal of the present invention.

[0002]

2. Description of the Related Art In recent years, portable telephone systems capable of performing not only voice communication but also data communication have become widespread. Systems that are widespread as such mobile phone systems include systems based on the PDC system and systems based on the PHS system. However, such a conventional PD
In a mobile communication terminal dedicated to C and PHS, only one communication channel that can be used is allocated, so that voice communication and data communication with different data formats cannot be performed simultaneously.

[0003] Therefore, if it becomes necessary to perform data communication during voice communication, it is necessary to disconnect the voice communication once, perform the data communication, and restart the voice communication after the data communication ends. There is inconvenience.

[0004] An example of a conventional portable telephone system which eliminates such inconvenience and enables simultaneous communication of data communication and voice communication is described in JP-A-2000-13858. This conventional portable telephone system realizes simultaneous communication of voice communication and data communication by using an empty slot of a channel used for communication.

[0005] However, this conventional technique has the following problems. In the current mobile phone system, it is specified that a channel used for communication can use only one slot. Then, a channel used for communication is performed from the base station to the mobile communication terminal using an empty slot, and is used by notification from the base station. Therefore, after the base station specifies the channel to be used for communication and starts communication using the channel, there is no method for notifying the mobile station of a new communication and the channel to be used from the base station to the mobile communication terminal. .

Accordingly, in order to realize the above-described conventional technique, the specifications of the current portable telephone system are changed, and an empty slot is designated from the base station to the mobile communication terminal separately from the channel in communication. Have to be able to do that. Therefore, the present invention cannot be realized without changing the current system.

The PDC communication system and the PHS communication system have different usable areas, communication speeds, sound quality when moving, and the like due to differences in the communication systems. These PDC and PH
PH to compensate for the shortcomings of S

C composite terminals have been put to practical use.

[0008] In such a composite terminal, PHS and PDC are used.
If a wireless device corresponding to each of the communication methods is provided and a calling process occurs, a PHS or PD
The communication is started by selecting one of the communication systems C.

[0009] However, even in such a combined terminal of PDC and PHS, only one communication channel is used in the conventional system, so that another new communication can be started during one communication. Therefore, simultaneous communication of voice communication and data communication could not be performed.

[0010]

However, the conventional mobile communication terminal described above has a problem that one terminal cannot simultaneously perform voice communication and data communication.

It is an object of the present invention to provide a mobile communication terminal which enables simultaneous communication of voice communication and data communication with one terminal.

And a voice / data switching control unit for performing the processing of the outgoing call by the other wireless device that is not currently in communication when the outgoing call occurs.

In another mobile communication terminal of the present invention, the first
Is a wireless device based on the PHS communication method,
May be configured as a wireless device based on the PDC communication method.

According to the present invention, when a new communication is generated during communication by the first wireless device, the transmission process is performed by the second wireless device. Simultaneous communication of communication and data communication can be performed.
