Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paging communication system used for pagers and the like. In particular, the present invention relates to a bidirectional paging communication system having a response signal from a paging terminal.

〔overview〕

The present invention provides a paging communication system used for pagers and the like, in which the paging terminal includes means for transmitting a response signal when detecting a call to its own terminal, and the radio base station includes means for receiving the response signal; By including means for transmitting the response status from the paging terminal and its paging terminal number to the control station after receiving this information, it is possible to perform two-way paging communication, confirming the call, receiving a response from the owner of the paging terminal, Furthermore, it is possible to determine the area where the person is located.

[Conventional technology]

In the conventional paging communication method, a wireless base station transmits a terminal number (rD) that designates a specific one of a plurality of paging terminals or a specific group of terminals, and the paging terminal receives it and assigns its own terminal number. Only when there is a loss, the owner of the paging terminal is notified of the call. This call notification is performed by sound, light, vibration, or voice, and more recently, a method has been developed in which numbers or alphanumeric characters are displayed as a message.

The paging call processing procedure of such a conventional paging communication method will be described below.

■ The caller uses a telephone to dial the control station.

■ The telephone network connects the control station to the calling telephone. Typically, the control station sends a specific tone A to the telephone to indicate that it is connected.

■ The caller confirms this sound A and then dials the number of the paging terminal he wishes to call.

(2) The control station stops sending sound A when it starts receiving this number, and sends specific sound B to the telephone when it finishes receiving all numbers.

■ The caller confirms this sound B and then dials the message (multi-digit number in the case of a numeric display type paging terminal) to be sent to the paging terminal. At this time, at the end of the message dial, for example, in the case of a button telephone, # is pressed.

(2) When the control station starts receiving the message, it stops sending the sound B, and upon receiving this #, it sends a specific sound C indicating the end to the telephone set.

■ The caller hears this sound C and ends the calling operation.

This also breaks the telephone network path between the telephone and the control station.

Note that even in the case of a data network, this calling procedure is performed in the same manner as in the data network via a data terminal.

The paging terminal number and message received in such a calling procedure are sent to all wireless base stations via data communication lines and transmitted by radio waves. The transmitted paging terminal number is received and displayed on the paging terminal having that number, thereby completing the call.

[Problem that the invention seeks to solve]

However, since such conventional paging communication methods are one-way communication, the calling party has no way to know that the calling signal has definitely arrived to the called party, and there is no way to know whether the paging terminal has been paged or not. The call procedure ends without the caller knowing what happened. That is, the calling party will not be contacted by the called party by telephone or other means.
There was no way to know that the call signal "reliably arrived."

To address these problems, conventional measures have been taken to increase the radio output of the radio base station to increase the probability that the paging signal will reach the paging terminal.

However, in this case as well, there are blind areas inside large buildings, tunnels, and underpasses, under guards, behind buildings, and near the periphery of the service area, and if the paging terminal owner happens to be there, It cannot be said that the call signal will definitely arrive. Further, if the paging terminal is turned off by its owner, it is impossible to receive a paging signal.

Thus, it is generally said that the percentage of call signals that do not reach the called party is in the range of several percent to 10 percent.

In addition, when the conventional paging communication method, which is a one-way communication method, is adopted within a single building, campus, or factory with a large area, it is difficult for paging terminal owners to enter and exit these service areas. When the number of calls is high, there is a greater possibility that a paging signal will not reach the paging terminal.

Therefore, the number of cases in which a call was made but the callee was not reached increases. Moreover, since the calling party cannot know this fact, the convenience of paging communication is greatly reduced.

As explained above, in the conventional paging communication method,
This method has problems due to the fact that it is a one-way communication.

The present invention solves these conventional problems,
It is an object of the present invention to provide a paging communication system having a response signal from a paging terminal.

The present invention is characterized in that it includes means for transmitting the response status from the paging terminal and the paging terminal number to the station.

[For production]

The first aspect of the present invention is that when a paging terminal detects a call to its own terminal, it transmits a response signal, and after receiving the response signal, the radio base station sends a control station a response status from the paging terminal and the paging terminal. By transmitting the number and notifying the caller, two-way paging communication is possible and the call can be confirmed.

Furthermore, by providing the paging terminal with a means for sending a message together with its own terminal number as a response signal, it is possible to receive a message response from the owner of the paging terminal.

Furthermore, the radio base station measures the field strength of the received radio wave of the response signal and sends it to the control station, and the control station calculates the maximum value of the strength measurement values from each radio base station and calls that non-VAA base station. By notifying the owner, you can find out the area where this owner is located.

The second aspect of the present invention is that in order to facilitate the reception of response signals from paging terminals, a reception-only wireless base station is provided, so that response signals can be easily received.
Furthermore, the location of the paging terminal can be determined accurately.

A telephone a65 is connected via the telephone network 60, and a data terminal 75 is connected via the data communication network 70.

Note that these telephone networks 60 and data communication networks 70 are
It may be a public network, an in-house communication network, or any other network.

In the radio base stations 20, 30, and 40, a reach area of each output radio wave is formed corresponding to each of them.

Here, they are respectively small service area 20a,
They are called 30a and 40a. Each small service area 20
a, 30a and 140a are collectively referred to as a service area.

In this embodiment, each small service area 20a, 30a,
Although the ranges 40a are shown as independent ranges, they may overlap.

Within each of the small service areas 20a, 30a, and 40a, there are paging terminals (PT) 25, 35, and 45, each of which is ready to receive services.

The first aspect of the present invention is characterized in that each radio base station 20, 30, 40 has a paging terminal 25, 35, 4, in addition to a means for transmitting a paging terminal number and a message.
After the receiving operation, the control station 10 transmits the response status and the responding paging terminal number to the control station 10.
and means for transmitting data to each paging terminal 25.35.
45 has means for transmitting a response signal.

The paging call processing procedure of the paging communication method of the present invention will be described with reference to the case where a telephone network is used.

- The caller uses the telephone 65 to dial the control station IO.

(2) Telephone network 60 connects control station 10 to calling telephone 65. Normally, the control station 10 sends a specific tone A to the telephone [65] to indicate that it is connected.

■ The caller confirms this sound A and then dials the number of the paging terminal he wishes to call.

(2) When the control station 10 starts receiving this number, it stops sending the sound A, and when it finishes receiving all the numbers, it sends the specific sound B to the telephone 65.

- The caller confirms this sound B and then dials the message (multi-digit number in the case of a numeric display type paging terminal) to be sent to the paging terminal. At this time, at the end of the message dial, a specific key is pressed, for example, the # key in the case of a button telephone.

The above is the same as the conventional method. Hereinafter, the system of the present invention is as follows: (1) The control station 10 stops sending sound B when it starts receiving the message, and furthermore, upon reception of this # signal, sends a specific sound to the telephone for a predetermined period of time (several seconds) to indicate the completion of normal reception. 6
Send to 5. At the same time, the received paging terminal number and message are sent to all radio base stations 20.30.40 via the data communication line 52.53.54.

■ Each radio base station 20.30.40 transmits this information via radio.

(2) When the paged paging terminal receives this information, it transmits a response signal to the radio base station 20.30.40.

■ Upon receiving this response signal, the radio base station 20.30.40 transmits the paging terminal number and information indicating "response signal reception complete" to the control station IO through the data communication line 52.53.54.
Send via. If no response signal is received, step 2 is repeated a predetermined number of times after a predetermined time (in seconds). If the response signal is still not received, information indicating "response signal not received" is transmitted via the data communication lines 52, 53, and 54.

[Phase] According to information from the wireless base stations 20, 30, and 40, the control station 10 sends a specific sound E or announcement to the telephone 65 that indicates the presence or absence of a response signal from the paging terminal.
Send to.

0 The caller plays this sound E or the announcement and ends the calling operation. As a result, the telephone 65 and the control station 1
The telephone network path between 0 and 0 will also be cut off.

Even in the case of the data communication network 70, this calling procedure can be performed in a similar manner to the calling procedure of the data communication network via the data terminal 75.

Through the above operations, the calling party can know whether or not the call has reached the paging terminal.

Note that, in addition to the configuration shown in this embodiment, the control station 10 may also utilize an electronic exchange having an electronic communication channel or the like.

Further, the data communication method performed between each radio base station 20.30.40 and the control station 1o via the data communication line 52.53.54 may be a known data communication method, and the method of the present invention Since this is not particularly relevant to the configuration and implementation, its explanation will be omitted.

Next, an example of a communication method between the radio base station 20.30.40 and the paging terminal 25.35.45 will be described.

FIG. 2 is a diagram showing a frame structure of a signal from a radio base station 20.30.40 to a paging terminal 25.35.45, and this is called a paging signal (PGS) 100.

FIG. 3 is a diagram showing the frame structure of a signal from the paging terminal 25.35.45 to the radio base station 20.30.40, and this is called a response signal (R3P) 1)0.

Same bit! 1J1) 1) (30 bits) is for bit synchronization of radio base stations 2o, 3o, and 4o with response signals from paging terminals 25, 35, and 45. It is a repetition of rolol J, and bits can be synchronized even with minute radio waves. The length is set to 30 bits to facilitate synchronization. Frame synchronization 1) 2 (1) bit) is used to indicate the start of one frame of the response signal, and has a fixed bit pattern. The first information 1)3 (32 bits) is used to send the responding paging terminal number.

The response signal 1)0' shown in FIG. 4 has the frame structure shown in FIG. 3 with a time slot of second information (INF2) 1)4 added.

This second information 1)4 (32 bits) corresponds to embodiment (2) of the present invention and enables advanced paging communication. That is, for example, paging terminal 25.

sends this second information 1) 4 to the control station 10, and the control station 1
0 sends an announcement or data to the telephone 65 or the data terminal 75 depending on the content of this second information. Therefore, the caller is paging terminal 25.35
．． It is possible to know the pressed state of the 45 function keys.

FIG. 5 shows the first information 103 to the nth information 105 of the calling signal 100 and the first information 1 of the response signal 1) 0.1) 0'.
) 3 and second information 1) 4. FIG.

Of the 32 bits, the first bit is the second to the 21st bit.
This bit is used to indicate whether the content of the bit indicates a paging terminal number, a message, or additional information; ``0'' indicates a paging terminal number, and ``1'' indicates a message or additional information.

The 22nd to 31st bits are B for error detection.
This is the CH error detection code. That is, the 1st bit to the 21st bit is set as a polynomial having terms from Xff+ to XIO, and the generating polynomial X I O+ X q + X It + X b +
This is a BCH code that changes the remainder after dividing by X S + X 3 + 1 from X9 to Xo. This X9 to Xo are input from the 22nd bit to the 31st bit. The 32nd bit is a bit for assigning odd parity to the 1st to 31st bits.

Therefore, in this embodiment, the paging terminal number is
Bits up to the 19th bit are used.

In this case, 218 numbering is possible. 20th
The bit and the 21st bit are used as a sub number. Sub numbers are "00", "01", "10", "1)"

By assigning this sub number to 35.45, it can be used appropriately. That is, the caller specifies a sub-number in addition to the normal paging terminal number when making a call.

FIG. 6 is a block diagram showing the configuration of an embodiment of the wireless base station of the present invention.

The wireless base station 20 (30, 40) is a modem (MDM)
21), Data link control unit (DLC) 212
, control unit (CONT) 213 , call control unit (PCN)
T) 214, transmitter (TX) 215, antenna coupler (ACP) 216, receiver (RX) 217
, a response control unit (RCNT) 218 and a response signal level detection unit (RLVL) 219.
and an antenna 22.

From the data communication device 13 of the control station 10, the data communication line 5
2 is demodulated by the modem 21) and received by the data link control section 212.

The control section 213 is composed of a microcomputer and a memory, and the received data is read into the memory, and the analyzed paging terminal number and message are sent to the call control section 214. The call control unit 214 generates transmission data based on the frame configuration and bit configuration shown in FIGS. 2 and 5, and stores it in the queue buffer. There are a plurality of waiting buffers, and data to be transmitted is sequentially sent to the transmitting section 215 from one of the plurality of waiting buffers storing data according to the transmission speed of the transmitting section 215. The transmitting unit 215 includes a modulating unit (the modulation method does not particularly matter) for transmitting data to be transmitted using radio waves at a constant rate (for example, 1200 vod/sec), and a power amplifying unit for the modulated signal. There is. The power-amplified calling signal is supplied from the transmitter 215 to the antenna coupler 216, and is transmitted from the antenna 22 as a radio wave.

When the response signal from the paging terminal is received by the receiving section 217 via the antenna 22 and the antenna coupler 216, the receiving section 217 demodulates the received signal and sends it to the response control section 217.
Send on 18th. The response control unit 218 analyzes this demodulated data according to the frame structure shown in FIG. 3 (FIG. 4). Here, the first information (and second information) is B C
Verification is performed using the H code and parity check, and a response signal is sent to the control unit 213 only when it is normal.

The control unit 213 compares the paging terminal number previously transmitted as a paging signal with the paging terminal number received as a response signal, and when they match, sends the first information along with information indicating "response signal reception complete". The paging terminal number (and second information) is transmitted to the control station 10 via the data link control unit 212 and modem 21).

By the way, if the response signal is not normally received within a predetermined time (in seconds), the control unit 213 sends the paging terminal number and message to the call control unit 214 again a preset number of times to perform retransmission processing. I do. If a normal response signal is not received even after retransmission processing is performed a predetermined number of times, the paging terminal number is transmitted to the control station 10 along with information indicating that "response signal has not been received."

Note that the response signal level detecting section 219 measures the electric field strength of the received radio wave of the signal received by the receiving section 217. Numerical information indicating the electric field strength of the received radio wave is sent to the control unit 213 together with information indicating "response signal reception complete" and the paging terminal number (and second information) of the first information, and further sent to the control station 10. Ru. When the control station 10 receives information indicating "response signal reception complete" from a plurality of radio base stations, it determines the radio base station having the highest received radio field strength among them.

This indicates that the called party who owns the paging terminal has the highest probability of being within the determined small service area of the wireless base station. Therefore, by announcing or otherwise notifying the calling party of the name of the sub-service area, the calling party can learn the area in which the called party who owns the paging terminal is located.

The communication control unit (CCU) 220 will be described later.

FIG. 7 is a block diagram showing the configuration of an embodiment of the paging terminal of the present invention.

The paging terminal 25 (35, 45) has an antenna 25
0, antenna coupler (ACP) 251, receiving section (R
X) 252, decoder (DCD) 253, control unit (CO
NT) 254, encoder (E CD) 255, transmitter (TX) 256, continuous memory (ROM) 2
57, a sound generating section (SPD) 258, a speaker 259, a message display section (DSP) 260, and crystal oscillators 261 and 262. Furthermore, a configuration including a function key (FK) 263 may be adopted.

A paging signal received by receiving section 252 via antenna 250 and antenna coupler 251 is demodulated and sent to decoder 253. The output of the crystal oscillator 261 is used for demodulation processing in the receiving section 252. The decoder 253 performs bit synchronization and frame synchronization of the calling signal, and further sends information after the first information to the control unit 254. The control unit 254 uses the BCH error detection bit and parity bit of the first information, which is the paging terminal number, to check whether normal reception has started.

If normal reception is confirmed, it is checked that the first bit of the first information is "0" indicating the paging terminal number, and the contents of the second to 19th bits (paging terminal number) are The number is compared with the number of the paging terminal itself stored in the read-only memory 257. If this comparison does not match, it means that the own paging terminal is not the one that has been called, and the subsequent operations are stopped. If there is a match, the message information after the second information is sequentially checked using the BCH error detection bit and the parity bit. When normal reception of all message information is confirmed, the number of the paging terminal itself is stored in a specific memory area of the control unit 254 in order to send a response signal, and the encoder 255 is activated.

On the other hand, the control unit 254 drives the sound generation unit 258 to generate a specific sound or voice from the speaker 259 in order to notify the paging terminal owner that the paging terminal has been called.

Furthermore, of the data received after the second information, the contents of the second bit to the 21st bit are displayed on the message display section 26.
Send to 0. The message display section 260 normally uses a liquid crystal display with 10 to 20 characters, so if the message sent is longer than this, the message is displayed one by one using a scroll function or the like.

The activated encoder 255 generates bit synchronization and frame synchronization of the response signal, and sends them in accordance with the transmission speed of the transmitter 256 (for example, 1200 vod/sec). Thereafter, first information (paging terminal number) stored in a specific memory area of the control unit 254 is sent. The transmitting section 256 includes a modulating section and a power amplifying section for the modulated signal. The output of the crystal oscillator 262 is used by the transmitter 256 to obtain stable wireless output. The output of the transmitter 256 is transmitted as radio waves via the antenna coupler 251 and the antenna 250.

Here, the function key 263 is provided for responding to a message to the caller as second information of the response signal.
The control unit 254 reads the state of the function key 263 next to the number of the paging terminal itself as a response signal, stores it, and sequentially sends it out.

Incidentally, the output power of the transmitter 256 of the paging terminal is much smaller than that of the wireless base station name transmitter 215. Therefore, in order to receive the response signal of the paging terminal as accurately as possible, or to accurately determine the location of the paging terminal, it is necessary to arrange a large number of reception-only radio base stations.

FIGS. 8 and 9 are diagrams showing a configuration example of a paging communication system according to the second aspect of the present invention, which includes a reception-only radio base station.

In the configuration example shown in FIG. 8, in addition to the radio base station 20 having transmitting and receiving functions, reception-only radio base stations 310, 320, and 330 are appropriately arranged within this small service area 20a.
They are connected to the data communication device 13 of the control station 10 via data communication lines 351, 352, and 353, respectively. This receive-only radio base station 310 (320, 330) is composed of a receive-only radio base device 31) and an antenna 312, and the receive-only radio base device 31) is
1 (31, 41) except for the transmission system, the other configurations and functions are the same.

In the configuration example shown in FIG. 9, a wireless base station 20 having a transmitting and receiving function has data communication lines 451. Connected via 452.453.

In this case, the configuration of the radio base device 21 of the radio base station 20 includes a communication control unit (CCU) 220 shown by a broken line in FIG. 6, and communicates with the reception-only radio base stations 410, 420, and 430. In addition, reception-only wireless base station 410.420
．． The configuration of 430 is the reception-only radio base station 3 shown in FIG.
It may be equivalent to 10.320.330.

In this way, in the configuration example shown in FIG.
．． 453 to the communication control unit 220 of the wireless base device 21
In this case, the control station 10
The burden of this will be reduced. In other words, the wireless base station 20 is connected to all reception-only wireless base stations 410 and 420.
．． Response signal sent from 430 and wireless base station 2
By having a function to determine the wireless base station name or number indicating the highest field strength of received radio waves from among the response signals received by itself and transmit it to the control station 10, the control station 10 uses a separate reception-only radio. Processing can be done without being aware of the base station.

It is also possible to mix the configurations shown in FIGS. 8 and 9.

〔Effect of the invention〕

As explained above, the present invention allows the radio base station to receive a response signal from the paging terminal and notify the control station and furthermore the calling party, whereby: ■ the calling party owns the paging terminal that called; It is possible to know whether or not the person is within the service area, as well as the service area where the person is located.

■ A paging terminal with function keys allows the caller to immediately know the status or intention of the paging terminal owner.

- By providing a reception-only radio base station, response signals can be received accurately and the location service area can be more accurately determined.
