Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device capable of automatically connecting to a telephone having a telephone number based on telephone number data received by using a pager receiving function.

[0002]

2. Description of the Related Art Recently, mobile phones have been remarkably widespread and many people are using them. In addition, a so-called pager that enables a call function to call only a specific person wirelessly and a simple incoming of character data is also actively used, and an era in which communication can be easily performed using various communication media is approaching.

Since the mobile phone is capable of bidirectional communication, it can exchange a large amount of information quickly, but on the other hand, it consumes a large amount of power not only during a call but also during reception standby, and is not suitable for long-term use. However, there is a drawback that the service area where communication is possible is narrow.

On the other hand, the pager has a drawback that it can transmit information unilaterally and the amount of information that can be transmitted is small. However, the pager can be formed in a small size, consumes less power, and can be used for a long time. It is possible and the service area is wide.

Therefore, conventionally, it has been proposed to house both a mobile phone and a pager in the same housing. In addition, a communication system called a next-generation cordless telephone system is currently under study, which means that mobile phones can be used in homes just like the cordless handsets of current cordless telephones, and they are also on the street. It is a telephone system that can be used as an existing mobile phone. That is,
This is a communication system in which a base station called a cell or a teleport is provided outdoors, on the premises, or in a general home if necessary, so that a telephone call can be made anytime within the reach of radio waves from these base stations. However, in this case, it is extremely difficult for the carrier of the telephone to know which base station is currently in the coverage area. For this reason, it is considered that the call can be made only from within the communicable area of the base station for the time being, as a pre-stage for realizing a system that allows the telephone to be communicated regardless of where the telephone carrier is.

[0006]

[Problems of the prior art] However, even in such a case where the transmission is exclusively used, it is not possible to include the entire area within the communicable area due to the limited base station, and there are areas where the radio wave does not reach. , It may happen that the phone does not work. In such a case, you can go to the coverage area of the nearest base station and call again.However, since the location of the important base station is unknown, you should move to a location near the base station. I guess I might have entered the coverage area and try to call again. And it may happen that such a thing must be repeated over and over again.

[0007] Further, in order to operate the mobile phone while moving, it is necessary to drive it with a battery, and since it consumes a large amount of power as described above, it is necessary to repeat the call again and again while taking time to operate. However, there is a problem that when the phone is connected, the remaining battery capacity is almost exhausted and a satisfactory call cannot be made.

[0008]

SUMMARY OF THE INVENTION In consideration of the above-mentioned conventional problems, the present invention provides

The positive terminal of the battery 13 is grounded, and the negative terminal of the battery 13 is connected to the input terminal of the power supply circuit 14. Then, the voltage adjusted by the power supply circuit 14 so as to match each circuit is supplied to the pager receiving circuit unit 1, the switching circuit 12, the CPU and other circuits. Further, the voltage output via the switching circuit 12 is given to the wireless transmission / reception circuit 2 and the amplifiers 4 and 7.

FIG. 2 is an explanatory diagram showing the configuration of the registers set in the storage unit 8. In the figure, the display register DR is a register for storing data to be output to the display device. The received message storage register RR is a register for storing the received message received by the pager receiving circuit unit 1. The flag register F0 is a flag register for identifying whether or not there is an incoming call to the pager receiving circuit unit 1, and the flag register F1 is a flag register for identifying whether or not the automatic transmission mode is set. The register C is a register that functions as a counter for measuring time in redial processing described later. Further, the abbreviated number register S is a register for storing a telephone number and information related to the telephone number, and numbers are sequentially assigned from the top of a predetermined storage area of the storage unit 8 such as 01, 02, 03. A name storage unit SN for storing a name and a telephone number storage unit ST for storing a telephone number are provided in each storage area designated by a number, and the name and the telephone number are stored in association with each other. The flag register F1 can be set (automatic transmission mode) and canceled (manual transmission mode) by the operation keys of the key input unit 9.

FIG. 3 is a flow chart for explaining the operation of the portable telephone device shown in the embodiment. In the figure, first, in step S1, it is determined whether a message has been sent to the pager receiving circuit unit 1, that is, whether a pager has received a message. When there is no incoming call,
After the execution of the program shown in this flowchart is completed and other processing not shown is executed, the process returns to step S1 again.

When a pager arrives, "1" is set in the flag register F0 in step S2.
Next, in step S3, the alarm unit 11 performs an alarm process for notifying an incoming call and a display process for displaying the transmitted message on the display device 10. Next, in step S4, the contents of the flag register F1 are checked to determine whether or not the automatic transmission mode is set. When the automatic transmission mode is not selected, the execution of the program shown in this flowchart is terminated.

When the automatic transmission mode is selected, it is determined in step S5 whether or not there is telephone number data in the message sent by the pager.
If there is no telephone number data, it is determined in step S6 whether there is abbreviated number data corresponding to the abbreviated number in the abbreviated number register S. If there is no abbreviated number data, the execution of the program shown in this flowchart ends.

As a result of the judgment in the step S5 or the step S6, when there is the telephone number data or the abbreviated number data, the switching circuit 12 is turned on in the step S7, and the radio transmitting / receiving circuit 2 and the amplifier 4,
Power is supplied to 7. That is, the wireless unit is turned on. Next, in step S8, it is determined whether or not the current location is within the communicable area. That is, a carrier search is performed to determine whether or not the carrier of the receiving channel has been received with a strength sufficient for communication. As a result, if the current location is within the communicable area, a call request is issued synchronously in step S9. Then, in step S10, automatic dialing is performed based on the telephone number data or the abbreviated number data sent from the pager. next,
In step S11, it is determined whether or not the call of the other party who dialed automatically has arrived. When you can connect to the other party,
In step S12, the sounding unit 11 performs a sounding process for notifying that the incoming call has been made, a call process for making a call is made, and the execution of the program shown in this flowchart is finished. In addition, the step S1
If it is determined that the call cannot be received at 1, the process proceeds to step S15 described below.

In step S8, if the current location is not within the communicable area, step S13
It is said that it is out of the communicable area by
Performs sound processing to notify by. Next, in step S14, the switching circuit 12 is turned off and the wireless unit is turned off. Then, a redial process is performed in step S15. After completing this redial process, the execution of the program shown in this flowchart is terminated.

The redial process is specified by referring to the contents of the register C for timer operation, each time it reaches a predetermined value, that is, at the predetermined time by the telephone number data or the abbreviated number data. Automatically dial the phone and call the other party. Note that the redial processing in step S15 is performed by substantially the same processing as steps S7 to S14 other than the timer operation routine.

In the above embodiment, the telephone number data received by the pager is automatically dialed in the communicable area, but it is received in order to easily call the other party outside the communicable area. It would be even more convenient if the telephone number data could be output as a dial tone and the telephone could be called via a telephone line.

[0022]

As described above in detail, according to the present invention, a message or telephone number data can be received from a person concerned such as a home or a work place, and the person concerned can automatically receive the telephone number data based on the received telephone number data. It is possible to make a phone call. Therefore, there is no need to perform a troublesome key operation when making a call. Further, when receiving the abbreviated number data and making a call to the other party based on the registered abbreviated number data, the name of the other party can be displayed immediately so that it is very convenient.
