Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital cordless, cellular / integrated wireless telephone device.

[0002]

2. Description of the Related Art In recent years, wireless telephone devices have come into wide use as their convenience and economy have improved.
Among them, cordless telephones with a limited usable range for offices and homes, digital cordless telephones that convert analog signals into digital signals for wireless communication, and wireless telephone service networks such as cellular telephones. Wireless telephone devices that can be used in a wide range have become widespread. In addition, an integrated telephone in which a digital cordless telephone and a cellular telephone are combined is also conceivable.

A conventional digital cordless, cellular / integrated wireless telephone device will be described below with reference to the drawings.

FIG. 2 shows a conventional digital cordless,
FIG. 1 is a block diagram of a slave unit of a cellular / integrated type wireless telephone device, where 1 is a cellular radio unit that transmits and receives a radio signal from a cellular base station in an analog system, 2 is a cellular antenna, 3 is a receiver, and 4 is a transmitter Talk section, 5 is a key operation section, 6 is a cordless radio section that digitally transmits and receives radio signals from a digital cordless base station, 7 is a cordless antenna for transmitting and receiving radio signals, and 8 is a cordless radio section 6. A voice decoding unit that decodes the demodulated digital signal into a voice signal, a voice encoding unit 9 that encodes the voice signal input from the transmitter 4 into a digital signal, and a power supply 10 to the above units Is a control unit for controlling the entire device and for correcting an error of a digital signal, and each of the blocks 1 to 10 constitutes a radio telephone device 12.

The operation of the conventional radiotelephone device configured as described above will be described.

When a user of the wireless telephone device makes a call,
The call destination base station and the call destination telephone number are designated by the key operation unit 5. Next, the control unit 10 receives the information from the key operation unit 5 and determines whether the cellular base station or the digital cordless base station is the call destination base station.
When the cellular base station is selected, the control unit 10 controls the cellular radio unit 1 to output a radio wave from the cellular antenna 2. Wireless telephone device after the called party goes off-hook
12 transmits and receives radio waves between the cellular base station and the cellular antenna 2. The radio wave received from the cellular antenna 2 is converted into a voice signal by the cellular radio unit 1 and is output as voice from the earpiece unit 3 via the control unit 10. The voice signal input from the transmitter 4 is converted into a radio signal by the cellular radio unit 1 via the control unit 10 and transmitted as a radio wave from the cellular antenna 2 to start a call.

When the digital type cordless base station is selected, the control unit 10 controls the cordless radio unit 6 to output the radio wave from the cordless antenna 7.
After the called party goes off-hook, the radio telephone device 12 transmits and receives radio waves between the digital cordless base station and the cordless antenna 7. The radio wave received from the cordless antenna 7 is converted into a digital signal by the cordless radio unit 6, is decoded into a voice signal by the voice decoding unit 8 via the control unit 10, and is output as voice from the earpiece unit 3. It The voice signal input from the transmitter 4 passes through the controller 10 and is encoded into a digital signal by the voice encoder 9. The coded digital signal is converted into a radio signal by the cordless radio section 6 and transmitted as a radio wave from the cordless antenna 7 to start a call.

[0008]

However, in the above-mentioned conventional radio telephone device, when a call cannot be made with one base station designated at the time of calling, the other base station is used by the user of the radio telephone device. There was the annoyance that the call could not be recalled unless specified by the operation.

The present invention solves the above problems and provides a radiotelephone device capable of automatically re-calling by designating another base station when a call with a designated base station cannot be made at the time of calling. With the goal.

[0010]

In order to achieve the above-mentioned object, the present invention determines whether or not it is possible to make a call to a designated base station in a digital cordless, cellular / integrated type wireless telephone device during standby. If it can be judged and the call can be made,
Has a call management unit for storing the callable base station information,
When a call is made, one of the call-destination base stations is specified by operating the key operation unit, and if the control unit determines that the call is unsuccessful, the other call-enabled base station is selected by the information from the call management unit. It is characterized by automatically re-calling.

[0011]

According to the present invention, when the call with the designated base station cannot be made, it becomes possible to automatically select another base station and call again according to the information of the call management unit.
The operation burden on the user can be reduced.

[0012]

FIG. 1 is a block diagram of a slave unit of a digital cordless, cellular / integrated type wireless telephone device according to an embodiment of the present invention. The blocks having the same functions as those in FIG. 2 are designated by the same reference numerals and the description thereof is omitted.

In FIG. 1, reference numeral 11 is a call management for judging whether or not a call can be made to a designated base station during standby, and stores a callable base station information when a call can be made. The call managing unit 11 is included in the wireless telephone device 12.

The operation of the wireless telephone device configured as described above will be described.

During standby, the control unit 10 controls the cellular radio unit 1
And the radio wave is output from the cellular antenna 2. The radio wave transmitted from the cellular base station is received by the cellular antenna 2, and the cellular radio unit 1 and the control unit 10
The call management unit 11 determines whether a call can be made to the cellular base station via the. If you can make a call,
Callable base station information (cellular base station) is stored. Next, the control unit 10 controls the cordless radio unit 6 to output a radio wave from the cordless antenna 7. The radio wave transmitted from the cordless base station is received from the cordless antenna 7, and the call management unit 11 via the cordless radio unit 6 and the control unit 10 determines whether or not the call can be made to the cordless base station. Done. If the call can be made, the call management unit
Callable base station information (digital cordless base station) is stored in 11.

When the user of the wireless telephone device 12 makes a call,
The call destination base station and the call destination telephone number are designated by the key operation unit 5. Next, the control unit 10 receives the information of the key operation unit 5, stores one of the call destination base station and the call destination telephone number in the call management unit 11, and selects the designated wireless unit. Subsequent call processing is the same as the conventional one. After the call operation, if the control unit 10 determines that the call is unsuccessful, the control unit 10 controls the designated radio unit to stop the radio wave transmission, and the call management unit 11
From the other callable base station and the callee telephone number stored in (1), the other base station that makes the re-call is selected and the wireless unit to be used is selected. The subsequent call processing is the same as the conventional example.

[0017]

As described above, the wireless telephone device of the present invention can be used when a call with a designated base station cannot be made.
It is possible to automatically select another base station and make a call again according to the information of the call management unit, and it is possible to reduce the operation load on the user.
