Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wireless telephone relay system, and in particular, in a relay area of a wireless relay device, there are a plurality of wireless devices to be relayed (the wireless telephone device is a wireless relay device), and The present invention relates to a wireless telephone relay system in which the wireless relay device itself accommodates one or more telephones.

Conventionally, in a wireless telephone system in which multiple wireless telephone devices can be connected to a general telephone network via a base station wireless transmitter/receiver and a line concentrator, multiple wireless telephone devices are placed in areas where wireless relay is required (relay area). In order to do this, each wireless telephone device requires a separate pair of wireless relay devices, which poses a disadvantage in that it imposes a heavy economic burden.
Furthermore, when accommodating one or more telephones in the wireless relay device itself, it is usually a simple method of manually performing a forced switching operation to enable meetings or interrupt calls, which increases the flexibility of the system. It was missing. Furthermore, even in the case of a wireless telephone device that requires wireless relay and the number of subscriber telephones that it accommodates is one, the controller of the wireless relay device normally requires almost the same functionality as the controller of the base station. Therefore, it is not simple, and if there are multiple relays, a complicated dedicated relay controller is required. Therefore, it has been desired that the relay controller be made common to the controller used in a multi-community radio telephone device accommodating a plurality of telephones, and be as simple as possible.

An object of the present invention is to provide a wireless communication system capable of accommodating at least one subscriber, which is equipped with a controller similar to that of a multi-community radiotelephone device and a simple switch, without using a special dedicated relay controller. By using a relay device, it is possible to relay operations to multiple wireless telephone devices placed within the relay area, and it is also possible to extend the relay distance by installing multiple wireless relay devices in series, or to use them in parallel. An object of the present invention is to provide a wireless telephone relay system with wide flexibility, such as enabling communication between wireless devices within a relay area.

The present invention will be explained in detail below.

17 A call between general telephones 11 and 12.

First, the first case, for example, a case where the general telephone 11 is called from the wireless telephone 53 (hereinafter simply referred to as a telephone if it is not confusing) belonging to the multi-community radio relay device 69 will be described. Here, the base station transmitting/receiving device 27 is transmitting the air line information, and the wireless relay device 69 also relays the information to other telephones 54.
(If used for relaying or talking, the wireless relay device 69 gives a busy tone to the call made by the telephone 53.) The wireless channel on which the idle line information is being transmitted is captured. It is assumed that When the handset of the telephone 53 is raised, the radio relay device 69 prohibits its own relay operation, sends a call signal to the base station, and then sends a signal indicating the identification number of the telephone 53 (hereinafter, if it is not confusing, simply the identification number). ) is sent. Line concentrator 30
receives the received output from the base station transceiver 27, receives these signals with a signal transceiver 47 connected to the wireless trunk 46, and sends the contents to the controller 50. When the controller 50 receives the call signal information, it disconnects the idle line information and sets the idle line information on any available wireless trunk in preparation for handling the next call in the system. Furthermore, when the controller 50 receives information on the identification number, it determines whether the content is within the range for setting up a new call. identification number) to the signal transmitter/receiver 47, and the radio trunk 46 and the base station transmitter/receiver 2.
7 to the wireless relay device 69. (If not, a disconnection signal is sent and the radio line is restored.) Furthermore, the controller 50 connects the corresponding subscriber trunk 33 and radio trunk 46 through the matrix switch 45 based on the identification number of the telephone 53. This activates the general telephone network exchange 10 through the subscriber line 15, and sends a dial tone to the subscriber line 15. On the other hand, wireless relay device 69
After confirming that the returned identification number is the identification number of the telephone 53, the telephone 53 is connected to the transmitter/receiver for the base station. Dial the phone number. Since the line concentrator 30 transfers the dial signal to the general telephone network switch 10,
The general telephone network exchange 10 acquires the subscriber line of the general telephone 11 and calls the general telephone 11.

Next, a second case, for example, a case where the wireless telephone 53 is called from the general telephone 11, will be explained. When the subscriber of the general telephone 11 picks up the handset and dials the telephone number of the wireless telephone 53, the general telephone network exchange 10
A call signal is sent to 5. At concentrator 30, this signal is detected on subscriber trunk 33 and reported to controller 50. When all the wireless trunks accommodated by the line concentrator are not available, the controller 50 activates the subscriber trunk to send a busy tone to the subscriber line 15, but at this point, the controller 50 transmits idle line information to the wireless trunk 46. is set, the controller 50 activates the signal transmitter/receiver 47, first cuts off the air line information, and then sends the identification number of the wireless telephone 53 corresponding to the subscriber trunk 33 to the wireless trunk 46 and the base station. It is transmitted via the transmitting/receiving device 27 to all wireless telephone devices and wireless relay devices that have captured this wireless channel.
When the wireless relay device 69 has captured the wireless channel, the wireless relay device 69 receives this identification number, selects the line of the wireless telephone 53 corresponding to the identification number, and sends a message to the base station. Send a response signal. While the controller is receiving a response signal via the base station transceiver 27, wireless trunk 46, and signal transceiver 47, the signal transceiver sends a bell ringing signal to the radio relay device 69, which is This continues until the response signal is disconnected by the subscriber of telephone 53 picking up the handset.

When the base station transmitting/receiving device 27 transmits an identification number, other wireless telephone devices and wireless relay devices that do not accommodate the wireless telephone with the corresponding identification number will be notified within a certain period of time after the air line information is disconnected. If it is unable to detect the identification number of the telephone it accommodates, it starts an operation to capture a new wireless channel through which the idle line information flows. Note that the wireless relay device 69
To explain the case where a multi-community radio telephone device and a multi-community radio relay device are each connected to a multi-community radio telephone device and a multi-community radio relay device, the identification number corresponding to the plurality of radio telephones is classified and determined for each device. Since the controller 50 of the line concentrator 30 has a function to determine which wireless relay device is in use (route determination function),
In this case, the controller 50 activates the subscriber trunk 33 and sends a busy tone to the subscriber line 15.

Next, in the third case, for example, the wireless relay device 70
A case where the general telephone 11 is called from the wireless telephone 58 will be explained. The wireless relay device 70 is
A busy tone is given to a call originating from the radio telephone 58 when it is used for relaying or talking, but when it is capturing a radio channel containing idle line information, that is, when the radio telephone 58 is used for relaying or talking, A call from the radio telephone 58 is handled when one of the relay devices 69 is not used for either a call or a relay and is relaying the idle line information transmitted by the base station transmitting/receiving device 27 or 28. Now, assume that the wireless relay device 69 is relaying the air line information sent by the base station transmitting/receiving device 27. By raising the handset of telephone 58, wireless relay device 70
prohibits its own relay operation, and sends the identification number of the telephone 58 to the wireless relay device 69 following the calling signal. On the other hand, upon receiving this calling signal, the wireless relay device 69 prohibits the telephones 53 and 54 that it accommodates from making calls and from receiving calls to them.
The calling signal and the identification number of the telephone set 58 are relayed to the base station transmitting/receiving device 27, and the relay operation state is established. Thereafter, the connection operation up to calling the general telephone 11 is accomplished in the same manner as in the first case.

Next, a fourth case, for example, a case where the wireless telephone 58 of the wireless relay device 70 is called from the general telephone 11, will be explained. When the telephone number of telephone 58 is dialed from general telephone 11, general telephone network exchange 10 selects subscriber line 20 and sends a ring signal to it if it is not busy. Subscriber trunk 38 of concentrator 30 detects this and reports it to controller 50. The controller 50 uses its group determination function and route determination function to
8 is possible.
That is, when the wireless trunk is not available, when the wireless relay device 70 is in relay operation or when another telephone it accommodates (in this case, the telephone 59) is in use for a call, and when the base station and the wireless relay device 70 When all radio repeaters in between (in this case radio repeaters 68 and 69) are in use for relaying or calling, the controller 50
8 returns a busy tone to the subscriber line 20. Now, it is assumed that the wireless relay device 69 relays the air line information sent by the base station transmitting/receiving device 27, and that the wireless relay device 70 captures it. Controller 5
0 is the wireless trunk 46 where the idle line information is set
The signal transmitter/receiver 47 is activated, first the idle line information is cut off, and then the identification number of the radio telephone 58 corresponding to the subscriber trunk 38 is sent to the radio line. The wireless relay device 69 relays the response signal from the wireless relay device 70 to the base station transmitting/receiving device 27, and at the same time prohibits the telephone set it accommodates from making a call.
Thereafter, the connection operation until calling the radio telephone 58 is performed in the same manner as in the second case.

Next, a fifth case, for example, a case where the general telephone 11 is called from the radio telephone 63 of the multi-community radio telephone device 73, will be explained. The multi-community radio telephone device 73 gives a busy tone to calls made by other telephones while one of the telephones accommodated therein is making a call using the wireless line. Also, when the wireless relay device interposed between the base station and the base station is in use for a telephone call and is not receiving idle line information, it similarly gives a busy tone to calls made by the telephone it accommodates. . Currently, the wireless relay devices 69 and 70 are relaying the air line information of the base station transmitting/receiving device 27, and the multi-community wireless telephone device 73
had received this, by raising the handset of the telephone 63, the multi-community radio device 73
sends a calling signal and the identification number of the telephone 63, and the wireless relay devices 70 and 69 enter the relay operating state as in the third case, and the base station transmitting/receiving device 27,
A connection to the regular telephone set 11 is achieved via the line concentrator 30 and the regular telephone network switch 10.

Next, a sixth case, for example, a case where the wireless telephone 63 of the multi-community wireless telephone device 73 is called from the general telephone 11, will be explained. When one of the telephones accommodated in the multi-community radio telephone device 73 is in use of a wireless line or a radio relay device interposed between the multi-community radio telephone device 73 and the base station is in a telephone conversation, the multi-community radio telephone device 73
When the line concentrator 3 is not receiving the idle line information, as described in the second case, the line concentrator 3
For calls to the wireless telephone device in this state, a busy tone is returned from the corresponding subscriber trunk in the concentrator 30 to the subscriber line. Ru. now,
Assume that the wireless relay devices 69 and 70 are relaying the air line information sent by the base station transmitting/receiving device 27, and the wireless telephone device 73 is receiving it. Due to the call from the general telephone 11, the telephone 63
The identification number of the wireless telephone 6 is transmitted, and a relay operation is performed based on the response of the multi-community wireless telephone device 73.
Connection to 3 is achieved.

Next, in the seventh and eighth cases, for example, the wireless telephone 53 of the multi-community radio relay device 69 and the wireless telephone 58 of the multi-community radio relay device 70 are talking to each other. The connection operation can be explained by a combination of the first case and the fourth case, or a combination of the third case and the second case. Similarly the 9th and 10th
In the second case, for example, the radio telephone 53 of the multi-community radio relay device 69 and the radio telephone 63 of the multi-community radio telephone device 73 communicate with each other; This corresponds to a combination of cases 1 and 2, or a combination of the fifth case and the second case.

Now, in the 11th and 12th cases, 1
It is not possible to communicate with each other between wireless telephone devices placed within a relay area relayed by only one wireless relay device and telephones accommodated by the wireless relay device. Therefore, in FIG. 1, it is impossible for the telephones 58 and 59 of the wireless relay device 70 to communicate with the telephones of the wireless telephone devices located in the relay area of the wireless relay device 70, but the standalone wireless telephone device 66 telephone 57 and the telephone 60 of the multi-community wireless telephone device 72
and 61 refer to the telephones 6 of the wireless telephone devices 67 and 73 arranged in the service area of the wireless relay device 70 by being relayed by the base station transmitting/receiving devices 27 and 28 and the wireless relay devices 68, 69, and 70.
It is possible to communicate with 2, 63 and 64. In the 13th and 14th cases, as shown in Figure 1, each wireless telephone device or It is easy to understand that communication between the wireless telephones of the wireless relay device is possible.

In order to conduct calls between wireless telephone devices within a relay area, at least two wireless relay devices are required for that area, and the call connection in the 15th case is not possible, so the explanation will be omitted. . In the 16th case, that is, in the case of a call between telephones housed in the same multi-community radio telephone device or multi-community radio relay device, for example, each telephone This is assumed to be a method such as a simple switching telephone system that accommodates the central office lines of all telephones and performs switching connections at each telephone, and the explanation thereof will be omitted. The 17th case is a switched connection in a normal general telephone network, so its explanation will be omitted.

FIG. 2 is a diagram illustrating a configuration example of a multi-community radio relay device (for example, 69) in FIG. 1, showing an embodiment of the present invention. In FIG. 2, the wireless relay device 69 accommodates two subscriber trunks, each of which is connected to one telephone set 53 and 54, respectively. In the figure, solid lines indicate the paths of voice calls or audio frequency signals and radio frequency signals, and broken lines indicate control lines.

The base station receiver 103 and the relay area receiver 113 of the wireless relay device 69 are always in a receiving state, but the base station wireless receiver 102 is in a receiving state at all times, except when making a call or transmitting a signal, according to instructions from the controller 104. The transmission output is cut off (the same applies to the radio receiver and radio transmitter of radio telephone device 2), and the relay area radio transmitter 114 has a specified output when the radio relay device 69 is relaying a call. However, the output is reduced (normally reduced to about 1/10 of the specified output) when relaying empty line information, and the output is cut off in other cases. Although such setting conditions regarding the output of the radio transmitter are not necessary conditions for a radio telephone relay system, they are effective in reducing opportunities for interference, intermodulation, etc. inside and outside the system, and by doing so, Therefore, the power consumption of the wireless telephone device and the wireless relay device can be reduced. Furthermore, as shown in FIGS. 2 and 3, in the embodiment of the wireless relay device according to the present invention, calls and responses from wireless telephone devices or wireless relay devices within the relay area are transmitted to the wireless receiver 113 for the relay area. Controller 10 by squelch signal
4 can be detected and enter the relay operation state, there is an advantage that the configuration of the wireless relay device can be simplified without requiring separate detection circuits for the calling signal and the response signal.

FIG. 3 is an explanatory diagram of the switching function of the embodiment of the switch 112 in FIG. 2, and each input/output signal in FIG. 3 will be explained with reference to FIG. 2 as follows. .

200: A modulated input signal to the base station wireless transmitter 102, which is a demodulated output signal 206 of the relay area wireless receiver 113 during wireless relay.
Further, when a call is made on a subscriber trunk accommodated by the wireless relay device, the signal is the output signal 204 of the signal combiner 108.

201: A signal for causing the controller 104 to execute a relay operation, which is a wireless receiver 1 for the relay area.
13 squelch signals 207 are transmitted.

202: An activation signal to the controller 104,
At the time of relay, it is the squelch signal 207 of the wireless receiver 113 for the relay area. In addition, when making calls on subscriber trunks accommodated by the wireless relay device, the off-hook signal 2 of the telephone corresponding to these subscriber trunks is
It is 05.

203: A control signal (switching signal) to a switch for switching each signal during radio relay and during a call on a telephone accommodated by the radio relay device,
It is sent from the controller 104.

204: An output signal of the signal combiner 108, which is given to the base station wireless transmitter 102 during a call on a subscriber trunk accommodated by the wireless relay device.

205: Off-hook signal of the telephone connected to the subscriber trunk accommodated by the wireless relay device.

206: Demodulated output signal of the wireless receiver 113 for the relay area.

207: Squelch signal of the wireless receiver 113 for the relay area.

First, the operation of the wireless relay device 69 in the first case in which the general telephone 11 is called from the wireless telephone 53 of the multi-community wireless relay device 69 will be explained with reference to FIG. When the wireless relay device 69 is capturing a wireless channel on which idle line information is flowing, the telephone 5
When the handset No. 3 is lifted, the corresponding subscriber trunk 110 is activated, the controller 104 is activated, and the switching signal 203 is applied to the switching device 112 to connect the switching device 112 as shown in FIG. (Thus, relay operations are prohibited), subscriber trunk 110, signal distributor 106 and signal combiner 1
08 using a matrix switch. On the other hand, when the wireless relay device 69 is not used for calls or relays, the controller 104 always controls the base station wireless receiver and the signal receiver 105 (airline information signal,
It works by instructing the mobile phone (which has a function to identify the telephone's identification number, etc.) to sequentially scan multiple wireless channels and capture the wireless channel through which idle information is flowing. Yes, but
If the wireless channel through which idle line information is being transmitted is not captured when the telephone 53 or 54 makes a call, the controller 104 transmits the output of its built-in busy tone generator to the matrix switch 1.
09 to the telephone 53 (or 54). A wireless channel on which air line information is flowing is received by a base station antenna 100, an antenna duplexer 101, and a base station receiver 103, and is sent to the controller 10 via a signal distributor 106 and a signal receiver 105.
4 recognizes the air line information and this wireless channel is set to be captured, the controller 104 activates the wireless transmitter for the base station and first generates a calling signal to the signal transmitter 07. Signal combiner 10
8, switch 112, base station wireless transmitter 10
2. The signal is sent to the base station via the antenna duplexer 101 and the base station antenna 100, and then the signal receiver 105 indicates that the antenna information from the base station has disappeared.
After confirmation, the signal transmitter 107 generates a signal representing the identification number of the telephone 53 and sends it to the base station via the same route as above. The subsequent connection operation is performed as described in the first case, and the general telephone 11 is called.

Next, the case where the wireless telephone 53 of the wireless relay device 69 is called from the general telephone 11 will be described.
Assume that the subscriber of the general telephone set 11 picks up the handset and dials the telephone number of the wireless telephone set 53.
It is also assumed that the wireless relay device 69 has captured a wireless channel through which idle line information is flowing. As explained in the second case above, the base station cuts off the antenna information signal and sends out a signal representing the identification number of the telephone set 53. When the controller 104 of the wireless relay device 69 receives the identification number of the telephone 53 through the receiving path, it sends a switching signal to the switch 112 to establish the connection as shown in FIG. and the signal distributor 106 and signal combiner 108 are connected. Also, wireless transmitter 1
02, the signal transmitter 107 generates a response signal, and the signal combiner 108, switch 112, base station wireless transmitter 102, and antenna duplexer 10 are activated.
1 and the base station antenna 100 to transmit a response signal to the base station. The subsequent connection operation is the second
The procedure described in the case of the second case is performed and the wireless telephone 53 is called.

Next, a case where the wireless relay device 69 performs a relay operation will be described. First, in the example described in the third case, that is, in FIG. 1, the wireless relay device 70
An example will be explained in which the wireless telephone 58 calls the general telephone 11. It is assumed that the relay area wireless transmitter 114 of the wireless relay device 69 relays and transmits the idle line information transmitted by the base station transmitting/receiving device 27, and the wireless relay device 70 receives this. telephone 5
By raising the handset of 8, the wireless relay device 7
0 prohibits the relay operation by its own switching device, and sends out the identification number of the telephone 58 following the calling signal to the wireless relay device 69. The wireless relay device 69 connects to the relay area wireless receiver 11 via the relay area antenna 116 and antenna duplexer 115.
3, upon receiving the calling signal, the wireless relay device 6
The controller 104 of 9 receives the squelch signal from the relay area wireless receiver 113 via the switch 112, activates the base station wireless transmitter 102, and sends the calling signal and the identification number of the telephone 58 to the base station. It is wirelessly relayed to the transmitting/receiving device 27. At the same time, the controller 10
4 sets the switch 112 to prohibit calls from the subscriber trunk accommodated by the wireless relay device 69, and sends calls to the relay area by a signal 201 for executing the relay operation as shown in FIG. The transmission output of the wireless transmitter 114 is increased to the specified output, and the two sets of wireless transmitter/receivers perform wireless relay. Thereafter, the connection operation until the general telephone set 11 is called is the same as that described in the first case.

Next, according to the fourth example, the wireless relay operation when the general telephone 11 is called by the wireless telephone 58 of the wireless relay device 70 will be described. As in the previous example, it is assumed that the relay area wireless transmitter 114 of the wireless relay device 69 relays and transmits the idle line information transmitted by the base station transmitting/receiving device 27, and the wireless relay device 70 receives this. By dialing the telephone number of the radio telephone 58 from the general telephone 11, the idle line information of the base station transmitting/receiving device 27 disappears and the identification number of the radio telephone 58 is subsequently transmitted.
These transmission contents are transmitted as they are to the base station antenna 100 and antenna duplexer 10 of the wireless relay device 69.
1. Radio receiver 103 for base station, signal distributor 1
06, wireless transmitter 114 for relay area, antenna duplexer 115, and antenna 11 for relay area
6 and then relayed to the wireless relay device 70. The wireless relay device 70 detects that the received telephone identification number is that of the telephone it accommodates, and sends out a response signal. In the wireless relay device 69,
When this is received by the relay area wireless receiver 113 via the relay area antenna 116 and antenna duplexer 115, the controller 104 receives the squelch signal from the relay area wireless receiver via the switch 112. Radio transmitter 102 for base station
, and causes the response signal to be wirelessly relayed to the base station receiver 27. At the same time, the controller 104 sets the switching device to prohibit calls from the subscriber trunk accommodated by the wireless relay device 69, and directs calls to the relay area by a signal 201 for executing the relay operation shown in FIG. The transmission output of the wireless transmitter 114 is increased to a specified output, and control is performed to perform wireless relay using two sets of wireless transmitter/receivers. The subsequent connection operation is performed in the same manner as described in the second case above, and the radio telephone 58 is called.

FIG. 2 shows an example of the configuration of a multi-community wireless relay device, and from now on, we will construct a wireless transmitter/receiver for the relay area (relay area wireless receiver 113, relay area wireless transmitter 114, antenna duplexer 115, If the relay area antenna 116) is removed, it becomes a multi-community radio telephone device. Such a multi-community radio telephone device can be used immediately as a multi-community radio relay device by connecting a wireless transmitting/receiving device for the relay area, so it has extremely high flexibility for system expansion after installation. can get. If you do not need that possibility, switch 1
12 can be omitted. Conversely, the controller of the multi-community radio telephone device activates the radio transmitter in response to a call originating or receiving a call from the subscriber trunk it accommodates, and furthermore, when a call is originating or receiving a call from any of the subscriber trunks. Since it has a control function that discriminates whether the connection is true or not, commands the connection operation, and generates the required signal, we can add a few functions to this and create a simple switch as shown in Figure 3. 112 means that it can be used as a control system for a multi-community radio relay device as an embodiment of the present invention.
In addition, in the case of a stand-alone radio telephone device, there is only one subscriber trunk in FIG. Needless to say, the controller can also be simpler.

As is clear from the above description, according to the present invention, (1) each telephone of a plurality of wireless telephone devices and wireless relay devices accommodating one or more telephones can be connected to a general telephone network; (2) A wireless relay device is capable of relaying to multiple wireless telephone devices and wireless relay devices within a relay area, and (3) A multi-community wireless relay device does not require a special dedicated relay controller. By adding a simple switch to a controller similar to that of the Zutai wireless telephone device, a control system is constructed that automatically switches between relay operations and calls made and received by the multiple telephones it accommodates.
