Field of invention

The present invention relates to a telephone apparatus suitable for application to, for example, a digital cordless telephone or the like.

Prior art

Recently, a number of digital cordless telephones and methods of using the digital cordless telephones have been proposed.

This digital cordless telephone is basically the same type as a cordless telephone widely used in ordinary homes and the like, and has a base station connected to a public switched telephone network (PSTN) within a predetermined range. It is composed of a cordless handset (cordless handset) which is carried and communicates with the mother telephone. A wireless telephone commercially available is capable of using a telephone within a range of approximately 10 m to 100 m from the mother telephone.

However, the digital cordless telephone described above is expected to replace the cordless telephone which is widely used at present. The great advantage of this digital cordless telephone is that up to four channels of Time Division Multiple Access (TDMA) are performed by modulating the digital signal to transmit and receive between the mother telephone and the telephone. You can pick it up and make a call from the side of a pay phone or the like (called a "telepoint").

When making a call from this remote location, the ID of the own telephone is also sent and based on this ID, for example, it is possible to determine whether or not the telephone is registered in advance, or to make a call for the call charge made after this determination ( It is thought to be able to identify the person who will pay the call charges).

Also, in a communication system with a moving body such as an automobile telephone system or a mobile telephone system, a cellular system is generally used. This cellular system divides the communication area into a plurality of cells, has a base station for each cell, and communicates with the base station and the mobile body. In this case, each mobile station performs transmission and reception with the base station, receives a control signal, and determines which cell can communicate with the base station.

The telephone system based on the digital cordless telephone described above has a large advantage compared to such a cellular telephone system in a simple configuration, that is, inexpensive.

The FM signal transmitted by the mother telephone 19a in a predetermined period (slot) is received by the antenna 1 of the telephone telephone 19b. The FM signal received by this antenna 1 is supplied to the tuner 2. The FM signal from the antenna 1 supplied to this tuner 2 is converted into a first intermediate frequency signal and then converted into a second intermediate frequency signal. The second intermediate frequency signal is supplied to the modem 3, and is FM demodulated by the modem 3 to become a digital voice signal. This digital audio signal is supplied to the CODEC 5 via the (TDMA) / TDD circuit 4, where it becomes the original analog audio signal. The analog audio signal is supplied to the speaker 7 and output from the speaker 7 as voice.

Next, the case where the FM signal is transmitted to the mother telephone 19a by the own telephone 19b will be described.

The voice collected by the microphone 6 is supplied to the CODEC 5 as an analog voice signal. After the analog audio signal supplied to this CODEC 5 becomes a digital audio signal, processing for transmission in the TDMA / TDD system is performed under the control of the communication control unit 8 in the (TDMA) / TDD circuit 4. The digital voice signal thus processed is supplied to the modem 3. The digital voice signal supplied to the modem 3 is converted into an FM intermediate wave signal and then supplied to the tuner 2. The FM intermediate wave signal supplied to the tuner 2 is switched every predetermined period (slot). Further, this switched FM intermediate wave signal is frequency-converted to become an FM signal, supplied to the antenna 1 after the predetermined signal processing is performed, and transmitted by the antenna 1 to the mother telephone 19a. .

Problems to be Solved by the Invention
