The first objective of the present invention is to economically provide an auxiliary device that can be used in a car or on a television, whereas the conventional automatic II telephone was only useful in a car. By providing a small version of the story, it attempts to solve the shortcomings of the car + 4 story, which will be described later.

The base layer group 5 is a relay between the general subscriber telephone network 4 and the mobile radio telephone network 9, and the wireless medium base layer group 5 is 6.7.8

The mobile radio telephone network is connected to the main body 19 of the wireless device in the mobile phone network by wireless communication.
13.14. +5.16.17 It is composed of wireless communication lines WM lines, and although only S@ is shown in Figure 1, it is actually composed of a larger number of wireless communication lines1-
1 The wireless device body 19 is connected to a connector (not shown at 2θ and 21) for transmitting and receiving calls for a car phone! It is connected to g22, and the car phone transmitter/receiver 22 occupies the operation section necessary for making calls, etc., so all operations necessary for the telephone can be performed from here. Next, the wireless device main body 19 will be explained. In car telephones, in order to effectively utilize the mobile radio telephone network 9, the radio communication line used for making calls is not fixed;
Since the system uses a method of searching for and setting up an empty line each time, the main body of the wireless device 19 is a so-called multi-channel wireless communication device that can communicate even if any of the many lines within one line are set up. There needs to be. For this purpose, vIu equipment such as a frequency synthesizer is required to switch a large number of channels, and when setting up the line (7)
Since the function as a telephone exchange magazine is partially carried out by transmitting and receiving control number 48 between Compared to a single channel type wireless communication 4:4 device in which the wireless communication 4M line is fixed to a single channel, it has a much more complex configuration and is inevitably larger in size1. In the current car phone system, in order to ensure a communication distance commensurate with the installation density of wireless relay base stations, the wireless device main body 19 is required to have a transmission output of several watts (specifically +31 is 5W1 or more). The reason for this will be explained in the following section.The reason for this will be explained below.A car equipped with a car telephone set W shown at 18 in FIG. When moving towards the vicinity, the wireless relay base station that communicates with the wireless device main body 19 automatically switches from 6 to 7, so that there is no interruption in the call. If the communication distance between the relay base station 6.7 and the wireless relay base station 6.7 is not at least 1/2 of the distance between the wireless relay base station 6.7 and the wireless relay base station 6.7, the wireless relay base As a result, it becomes impossible to communicate with any of the stations 6 and 7, and the mobile radio telephone network 9, which is constructed by installing a group of radio relay base stations 5 so that calls can be made over a wide area, cannot be effectively used. It disappears.

″ものとなる。(4) In other words, in the current car phone system, the wireless device body 19 used for this requires a transmission power of several watts (specifically, 5W) or more, and lowering the transmission power is difficult when making a call. In order to secure the required superstition output, it is extremely difficult to make the transmission section (d) smaller and lighter, and the power consumption is large. Become.

困雛な大きさ、重さとなってしまう。For these reasons, the wireless device main body 19 is small in principle.
It is difficult to reduce the weight of the device, and its power consumption is also large. Sub-1: The power source such as a battery that can be used for a long time is also quite large and wasteful, so if you remove the car phone device 1ts from the car and use it as a portable mobile phone ( 7. Even if you want to do so, the wireless device body 19
, a car telephone handset 22, a telephone H that can be used for a long time, etc., would require a size similar to that of a Torashifu, making it too large and heavy to carry.

る必要があり、実用化されていない。In these small areas, as car telephone equipment becomes smaller and lighter, it is likely that mobile phone functionality will be eliminated to some extent, but even if this were to happen, the current wireless relay bases would be By changing the configuration of the station group 5 and the mobile stationless aSta network 9 - (, increasing the installation density of the wireless relay base stations 6t7 and 8)
For example, it is not possible to reduce the output of the transmission 4 required for the main body 19 of the radio device by 61 holes, so the power consumption will not decrease drastically even if it is miniaturized, and it will last a long time within the range of a portable size. It is difficult to have a battery that can be used for a long time,
Furthermore, it is technically difficult to reduce the size and weight to a pocket-sized size.
There is C. By increasing the setting density of the wireless relay base station group 5, it can be used even if the transmission output of the wireless device main body 19 is smaller than the current one, and it is possible to
Although the method for downsizing is theoretically possible (ζ is IIJ), it has not been put to practical use because it requires changing the configurations of the current radio relay base station group 5 and mobile radio telephone m9.

まで小型軽量化する事が可能となる。。In the present invention, as a method to solve the above-mentioned drawbacks of car telephones, we have developed a pocket-type telephone that has automatic *telephone dialing and quadrivalent dialing for the purpose of making it possible to use the car phone even outside the car. A method is used to connect to the main body of the automobile no-tightening device through wireless communication. According to which method, a pocket phone is mobile and does not transmit or receive radio waves directly to the telephone network, so it can be used for a long time because it requires only a small output. Even including a possible power source, it is possible to reduce the size and weight to a size that can fit in a pocket (7).

Connector r-26+: Connector 27. A wireless repeater 28° is installed in a car, and a pocket telephone 30 is carried around to use a pocket telephone outside the city.
When you operate 30, a C car phone handset 22.
Since you can make outgoing calls, make 1459 calls, etc. in the same way as you operate 4 degrees, the drawbacks of the aforementioned self-I41 Den-Ayu are solved.
If you are outside the car, you can hear the signal of an incoming call and can make a call by responding to -4'<, so there is no need to leave someone in the car to answer the phone number. Also, if you need to make a call outside the car, you can make a call immediately without returning to the car.
In the example shown in the figure, signal distribution and coupling! Since it uses the ll1124, it is also convenient to use the Sil+22 for transmitting and receiving calls for car phones, and when using the phone in the car, the handset 22 for car phones is used. In addition to helping to conserve power for the pocket phone 30, there is no need to use the handset (I01) for a car phone at the same time to communicate between three parties. It has an additional function of being able to have a conversation.

As long as there is a car nearby, the phone can be used as a pocket phone, which saves time through quick communication, and there is no need to leave a person in the car to answer the phone. It is useful for saving labor, and it is also a convenient configuration that allows people who remain in the car to use the phone or make phone calls to other people.It also has a so-called disabled system that automatically calls the #L phone number when you are not in the car. Since the spread is reduced, traffic can be used more effectively and the effects of '46 etc. can be avoided.
