2, an MMI handler 13 and an AIR handler 14.

[0010] The MMI 10 controls a state transition caused by a user operation of the terminal. When the terminal performs wireless communication with the base station by each communication system, the AIR sequence 12 performs connection in outgoing and incoming calls, location registration, channel switching during communication, service identification, wireless state detection, and the like. Since the AIR sequences 12 need to be provided for each communication system, the AIR sequences 12 are provided by the number of communication systems that can be used by this terminal. MMI handler 1
Reference numeral 3 denotes a display unit 5 which is hardware for performing display and sounding.
And the speaker 8. The AIR handler 14 controls the radio unit 1 which is hardware of each communication system.

The AIR sequence 12 and the MMI 10 are independent as units, and data communication is performed between the units. When transmitting data from an individual AIR sequence 12 to the MMI 10, the data
Switching task 1 via internal AIR manager 15
6 is converted to the data structure of the MMI sequence 17 and transmitted by the switching task 16. Also,
The data from the MMI sequence 17 is also converted by the switching task 16 into the data format of the individual communication system,
The information is transmitted to the currently operating AIR sequence 12 via the AIR manager 15.

FIG. 3 shows a detailed configuration of the MMI 10 and A
FIG. 3 is a diagram showing a relationship with an IR sequence 12. MMI1
Inside 0, a plurality of AIR managers 15, switching tasks 16, and MMI sequences 17 are provided.

A plurality of AIR managers 15 also correspond to each of the plurality of AIR sequences 12, monitor and control the radio conditions detected by these AIR sequences 12, and pass the results through a switching task 16. To the MMI sequence 17.

The switching task 16 selects one of the plurality of AIR managers 15 and selects the MMI sequence 1
7 to switch the communication system. This switching is performed based on information on user operations and settings from the MMI sequence 17 or information on the wireless state from the AIR sequence 12. Then, information on the wireless state from the AIR sequence 12 is transmitted to the MMI sequence 17 via the AIR manager 15. Also, information such as user operations and settings from the MMI sequence 17 is transmitted to the AIR manager 15 via the AIR manager 15.
Transmit to sequence 12.

The MMI sequence 17 controls procedures such as operation, display, and sounding of the terminal communication device. That is, the input from the key matrix 3 is input here, and the input information is recognized. Further, it outputs display information such as a telephone number and a wireless state to the display unit 5. Further, a sounding command is output to the speaker 8. Also,
It outputs setting information and the like to be stored to the EEPROM 4 and extracts necessary information from the EEPROM 4. In addition to these, from the radio status transmitted from the AIR manager 15, each AIR sequence 12
It is determined whether or not the above operation is possible, and the communication system is selected.

Next, the operation of hardware when communication is performed in the terminal communication device will be described with reference to FIG. Key information input by the user from the key matrix 3 is sent to the control unit 2. Then, the control unit 2 sends the display data to the display unit 5 and sends the ringing data to the speaker 8. The dial data is output via the radio unit 1 and the antenna 9 based on the rules of each communication system. Modules other than the radio unit 1 and the control unit 2 that perform control specified in each communication system are commonly used in a plurality of communication systems.

Next, the operation of software installed in the control unit 2 when selecting a communication system will be described as the operation of each unit constituting the control unit 2 with reference to FIG. An appropriate communication system is selected from a plurality of communication systems by a user's key operation according to the purpose of use. The switching task 16 performs this switching. That is, the operation information input by the user from the key matrix 3 is stored in the MM in the MMI 10.
It is transmitted to the I sequence 17. MMI sequence 17
Transmits this operation information to the switching task 16, and the switching task 16 switches the AIR manager 15. When the AIR manager 15 is switched, the selected AIR sequence 12 is switched,
As a result, the communication system is switched to the communication system selected by the user.

Further, it is possible to set so that the selection of the communication system is automatically performed according to the radio condition of each communication system. At this time, the radio state of the communication system corresponding to the AIR sequence (1) is changed according to the AIR sequence (1) selected first.
It is transmitted to the MMI sequence 17 via the AIR manager 15 and the switching task 16. MMI sequence 1 determines that communication is not possible due to poor radio conditions.
7, the MMI sequence 17 instructs the switching task 16 to switch the AIR manager 15. In response, the AIR manager is switched from (1) to (2), and as a result, the AIR sequence is also switched from (1) to (2). And AIR
The wireless state according to the sequence (2) is checked, and if communication is possible, the communication system to be used is determined.

Further, the user can decide in advance the priority of the selected communication system.
For example, if the AIR sequence (2) is set to have a higher priority than the AIR sequence (1),
First, the AIR sequence (2) is selected. At this time,
If the AIR sequence (2) cannot be used due to out of service or the like, the switching task 16 causes the AIR
Switching to sequence (1). In addition, during the operation in the AIR sequence (1), the radio status of the AIR sequence (2) having a higher priority is confirmed at every preset time (for example, every 5 seconds).
Switching to IR sequence (2).

Further, it is possible to set by a user's operation such that a specific communication system is not selected at the time of the above selection. The general operation of the communication other than the above is the same as that of the conventional terminal communication device, and the description is omitted.
