せる必要があるため、実行が困難である。 As shown in FIG. 1, in the conventional line setting method of this type, in order to set up a line between a mobile station 1 and a fixed station 2, connections are made between other mobile stations 1 and 1', fixed stations 2 and 2', etc. A control unit that monitors and manages all frequencies in use.
CONT is provided so that, for example, when frequency f 2 is used between another mobile station 1' and fixed station 2', frequency f 1 is allocated between mobile station 1 and fixed station 2. Even if frequency f 1 is used between another mobile station and fixed station, if the distance is far and there is no mutual interference, the frequency f 1 is used between mobile station 1 and fixed station 2. can also be assigned. In such conventional systems, frequency management is unified, so line settings can be easily made. but,
For example, when two mutually independent radio systems are installed in close proximity, as in the case of a cordless telephone, there is a drawback that they interfere with each other because a common control section cannot be installed. For example, if cordless telephones are installed in neighboring houses, a common control unit cannot be installed because the managers are different. Even if a common control unit were installed, it would be difficult to implement because it would be necessary to provide a communication line and increase the capacity of the control unit each time a new cordless telephone is installed.
本発明の目的は、上述の従来の欠点を解決し、

定することを特徴とする。 In the wireless line setting method of the present invention, the mobile station and the fixed station constantly monitor a plurality of wireless channels through which calls can be made between the mobile station and the fixed station, memorize empty channel numbers that are not in use, and then make a call. Sometimes, the calling party notifies the other party of the memorized vacant channel number via the control channel, and the called party compares the notified vacant channel number with its own memorized vacant channel number and uses it in common. Can do 1
After selecting one channel, the calling party is notified using the control channel, and a radio link between the mobile station and the fixed station is set up using the selected radio channel.

れている。 FIG. 2 is a block diagram showing an example of the configuration of a mobile station and a fixed station suitable for implementing the method of the present invention. That is, the mobile station 1 and the fixed station 2 include a control circuit 3, a synthesizer 4, a memory 5, a transmitter 6,
It is equipped with a control receiver 7, a communication receiver 8, and a telephone 9. Fixed station 2 uses telephone line 1 instead of telephone 9.
It may also be connected to 0. Now, it is assumed that N channels of radio waves are allocated between the mobile station 1 and the fixed station 2, and any channel can be used. However, if a channel currently in use is used between other mobile stations and fixed stations, mutual interference will occur. During standby, the mobile station 1 always monitors the N channels in sequence (for example, using a non-localized circulation method). That is, by using the communication receiver 8 as a level monitor and sequentially and cyclically switching the frequency of the synthesizer 4, the reception level of each channel is sent to the control circuit 3, and the control circuit 3 detects when the reception level is lower than the specified value. Record the lower channel number in memory 5. When these channels are used, at least there is no interference from downstream channels. The channel number can be known from the frequency or channel number signal sent from the synthesizer 4 to the control circuit 3. It is assumed that the maximum number of empty channel numbers that can be recorded in the memory 5 is n (≦N). The larger the value of n, the better, but unless at least one channel is commonly recorded as an empty channel between mobile station 1 and fixed station 2, a communication channel cannot be set. Therefore, it is determined based on the balance between the number of allocated channels N and the call loss, but specifically, it is related to the number of zone repetitions, etc., so it is selected as appropriate depending on the design of each system. Therefore, the memory 5 of the mobile station 1 stores 0 to n current empty channel numbers.

た空チヤネル番号とは必ずしも一致しない。 On the other hand, the fixed station 2 also stores the current empty channel number in the memory 5 by the same operation as described above.
With this channel, at least the upstream channel will not be disturbed. However, since the installation location is different from that of the mobile station 1, the empty channel number may partially differ from that of the mobile station due to differences in propagation loss. In other words, radio waves that are below a certain level at mobile station 1 may be received at fixed station 2 at above a certain level, and vice versa, so the empty channel number detected by the mobile station and the radio wave detected by the fixed station are This does not necessarily match the empty channel number.

ある。 Now, for example, if you want to make a call from mobile station 1 to fixed station 2, when you lift the hook on telephone 9 at mobile station 1, you will receive the empty channel number (0 to n) stored in memory 5 and the telephone number of mobile station 1. ID is transmitter 6
transmitted using a control channel from In the fixed station 2, a control receiver 7 constantly monitors the control channel. The control receiver 7 is controlled by the control circuit 3 to operate only when it detects the telephone number ID, and when it detects this ID, it receives the empty channel number sent from the mobile station 1. It is sent to the memory 5 via the control circuit 3. and,
The control circuit 3 compares the empty channel number stored in the memory 5 in advance with the empty channel number,
One matching channel number is selected and that channel is set as the communication channel. Then, the transmitter 6 transmits the telephone number ID of the mobile station 1 and the above communication channel number via the control channel. The mobile station 1 receives it with the control receiver 7 and sends it to the communication receiver 8.
and set the transmitter 6 to the channel. Also,
Similarly, in the fixed station 2, a communication receiver 8 and a transmitter 6 are set to the above channel. That is,
A wireless line is set up using the channel, and the telephone 9
is connected to the telephone line 10. Note that the fixed station 2 is
When a common empty channel number cannot be obtained by the above channel number comparison, the transmitter 6 sends the telephone number ID of the mobile station 1 and a busy signal, and the mobile station 1 receives this and sends a busy tone to the telephone 9. Send out. Even when the fixed station 2 makes a call to the mobile station 1, the line can be set by the same operation.

What is the telephone number (or identification number) ID of fixed station 2?
If mobile station 1 and fixed station 2 are on a one-to-one basis, they may have the same phone number, but if fixed station 2 is connected to multiple mobile stations 1, they may all have different telephone numbers. (Identification number) By setting an ID, each terminal can be identified.

Therefore, no matter how other mobile stations and fixed stations in the vicinity are arranged, it is possible to set up a communication channel that is free from interference.
