Description

Detailed Description of the Invention (Industrial Application!l!+') The present invention relates to a mobile communication system and its base station equipment and mobile station equipment, and particularly relates to practical use. The present invention relates to a mobile communication system that enables a small mobile station device that can communicate on both sides of a call, and its base station device and mobile station device.

(Prior Art) Various wireless mobile communication systems have been proposed in the past. Below, these mobile communication systems will be briefly explained.

(1) A car telephone system is a system that allows calls to be made and received from a mobile device. This system uses the so-called small zone method, which reduces the reach of radio waves output from radio stations in order to reduce the size and power of mobile terminals and increase the number of subscribers. ing. In other words, by adopting the small beam system, radio waves of the same frequency can be used repeatedly at radio stations separated by a certain distance, and radio waves can be used by many users.

In addition, this car phone system enables communication across zones by exchanging I/government ordinance records and tracking.

(2) A paging system such as a pager system is available as a system exclusively for calling mobile devices. This system uses a large zone system that uses relatively strong radio waves, so it is often possible to make calls even inside buildings, and the time it takes to monopolize the radio waves for each call is limited. Since it is short, you can increase the number of subscribers.

In addition, since the mobile device side terminal is for receiving W, it can be made small in size.

Note that recently, terminals that display simple data (numbers and characters) have also been proposed.

(3) In recent years, the Ministry of Posts and Telecommunications of Japan has proposed a new land mobile radio telephone system (Convenience Radio Phone, hereinafter referred to as CRP), which is a simple car telephone system. This system uses radio stations in a larger zone than general car telephone systems, and does not perform tracking and exchange, and as a result, equipment costs can be reduced.

(4) As an evolution of cordless telephones, there is Memoto Telegraph and Telephone Co., Ltd.'s office cordless telephone.

This system is a wireless communication system that is intended to be used within a predetermined area such as a business office.

(5) In Europe, including the UK, Telepoint (Cr2) has been proposed as a call-only system.

(Problems to be Solved by the Invention) The conventional technology described in 1 had the following problems.

(1) Since the car telephone system allows both calls to be made and calls received from a mobile device, it is necessary to fill the service area with wireless zones based on the small zone system, which requires a huge amount of capital investment.

In addition, in order to increase subscriber capacity, it is necessary to further reduce the wireless density, but in urban areas there are many factors that affect radio wave propagation, such as buildings, making zone placement/design difficult, and requiring capital investment. From this point of view, there are limits.

In addition, if the entire service area cannot be filled with wireless zones, that is, if there are dead areas where radio waves cannot reach, it may not be possible to communicate when needed, which is especially inconvenient when receiving calls. be. Also, since it uses weak radio waves, it cannot be used inside buildings as a general rule.

Furthermore, the size of the wireless zone determines the wireless power required for the system terminal, and currently, it takes a considerable amount of battery power to meet this power requirement and satisfy the practical use time. It requires a large capacity, making it difficult to miniaturize the terminal.

A mobile phone system using extremely small zones has also been proposed, and in order to economically realize front-line areas using extremely small zones, it is necessary to allow the existence of dead zones. However, due to the existence of this dead zone, while it is possible to make a call from a place with good reception for the husband's sake, in order to receive a call, it is necessary to be in a place with excellent reception, which is inconvenient. .

(2) In a call-only system such as a pager, when a call is made, it is necessary to contact the person using another communication means.

(3) Since CRP uses a relatively large zone system, the subscriber capacity is small. Furthermore, since the output of the mobile device cannot be reduced very much, it is difficult to downsize the portable terminal.

Furthermore, to ensure subscriber capacity, the talk time is R1
In some cases, it may be necessary to limit the number to 11 or make it exclusive for calls.

(4) For office cordless telephones, within a predetermined area of the office, etc.
The system can only be used by (Notu).

(5) Telepoint 1-(CT2) is, in principle, a call-only system.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to allow the existence of dead zones while making it possible to virtually make and receive calls from a mobile station device. In addition, in order to secure subscriber capacity, it is not necessary to restrict call time or dedicate terminals for making calls, and furthermore, it is possible to reduce the size of terminals. The purpose is to provide equipment and mobile station equipment.

(Means and Effects for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a calling base station that transmits predetermined data dialed from a calling side telephone to a mobile station device using a large synchronization method. , a group of call connection base stations for receiving calls from a mobile station device in a small zone type and making a call, a general public network, the calling base station and a call connection base station group; A base station device is configured by a switching center for this system that connects a line between the mobile station device and the telephone in response to a call made by the mobile station device, and a paging receiver that receives data transmitted from a base station; a storage device that stores the data; and an automatic call device that automatically calls the calling telephone based on the data; The present invention is characterized in that a mobile station device is constituted by a calling transceiver that makes a calling connection to the group of calling connection base stations. Another feature is that a mobile communication system is constructed using these base station devices and mobile station devices.

When calling the mobile station device, the telephone number of the nuclear mobile station is dialed, and at least the telephone number of the own station is also dialed, and the calling base station transmits at least the dialed data of the own station. Send the telephone number to the mobile station device. However, in a telephone system having a function of dynamically transmitting the telephone number of the own station r-1, it is possible to save the labor of dialing the telephone number of the own station.

When the mobile station device receives the data, it uses the data to automatically place a call to the calling party's telephone.

If the mobile station device is located within the service area of any of the call connection base stations that make up the call connection base station group, this automatic call will cause the call connection base station and A communication line between the mobile station device and the calling telephone is connected via the switching center for this system.

If the mobile station device is not located within the service area of any base station for calling and connecting, automatic When a call is made, a communication line between the mobile station device and the telephone on the calling side is connected.

(Example) The present invention will be described in detail below with reference to the drawings.

A switching center 22 for this system is connected to the switching center 22 for this system through an interconnection barrier exchange (cb+, barrier exchange for interconnection) 100, and to the switching center 22 for this system, there are base stations for call connection, each having antennas 23E to 23G... 23A to 23C (base station group 23 for outgoing call connection) are connected and arranged. This system switching center 22 and call connection base station group 23 have the same or almost the same configuration as the switching center and base station of the above-mentioned car telephone system, CRP, etc., and output from the mobile station device 7. It has a function of connecting a line to the general public network 19 or other mobile station equipment in response to a call request.

1. Each of the call connection base stations 23A to 23C constituting the call connection base station 7jl-23 is configured to output relatively weak radio waves, and is arranged in an extremely thin arrangement.

In addition, each of the call connection base stations 23A to 23C... is concentrated in areas where there are many call requests such as urban areas, and in areas where call usage is low, the existence of dead areas is recognized. It is located in

In addition, in the call origination connection system consisting of the switching center 22 for this system and the call origination connection base station group 23, the mobile phone 7 performs location registration and tracking exchange like a normal car phone system in a voice-centered system. There's no particular need.

In addition, by placing call connection base stations in buildings, underground malls, etc. as necessary, it is possible to make connections between conventional car telephones and mobile telephones (;
) Enables use in areas where telephones were not available.

Further, a calling base station 21 having an antenna 21E is connected and arranged in the switching center 22 for this system. This calling base station 21 is a base station dedicated to calling a mobile station device 7, which will be described later, and is the same as or almost the same as a base station of a pager system, and outputs relatively strong radio waves. The calling method by this calling basin station 21 is a so-called large zone method.

The mobile station device 7 is mounted on a car 8, for example.

This mobile station device 7 includes a radio 4, a telephone 5, and an antenna 6. The detailed configuration of this mobile station device 7 is shown in FIG. In FIG. 3, the same reference numerals as in FIG. 2 refer to the same or equivalent parts.

In FIG. 3, the radio 4 includes a calling receiver 1 that receives radio waves transmitted from the calling base station 21, and a calling transceiver that makes a call to the calling base station m23. 2, and a control device 3 that controls these devices. The control device 3 includes a microcomputer (
(not shown), which controls the calling receiver 1 and the calling transceiver 2.

The telephone 5 connected to the control device 3 is composed of a handset 5B and a stand 5A.

The hunt set 1-5B includes a dial key, a display device for various data (product display device, LED lamp, etc.), a power switch for the mobile station device 7, a call switch, an automatic call changeover switch, and other various operation switches. (none of which are shown) etc. are provided. The power switch is
The call switch supplies power to the calling receiver 1 and control device 3 of the radio 4, as well as the telephone 5, and the call switch further supplies power to the calling transmitter/receiver 2 of the radio 4 after the power switch is turned on. Provides power supply.

That is, when the power switch is on, only calls from the general public network 19 can be made, and when the call switch is on, calls to the general public network 19 can be made.

The automatic call υJ changeover switch is operated in step S1 in FIG.
2 will be described later.

FIG. 4 is a diagram showing an outline of the communication procedure when calling the mobile station device 7 from a general telephone among the operations of the mobile communication system according to the present invention. In the figure, the switching center indicates the system switching center 22 (FIG. 2).

The communication procedure shown in FIG. 4 will be explained in conjunction with FIG. 2.

First, when a call is made from a general telephone, a radio wave is transmitted from the calling base station 21 (FIG. 2) via the switching center 22 for this system, and the mobile station device 7 is called. When making an rjj call, dial the telephone number of the mobile station device 7 to be called from a general telephone, and also input prescribed data (the telephone number of the local telephone, the credit card number for making a credit card call, and the registered telephone number). etc., data necessary to make a call from the mobile device side). In other words, in this example, the calling party must have a credit card contract.

Note that this is to charge the calling party's general telephone for the cost of this call, and is not necessary if the calling party's mobile station device is to be billed.

Further, when calling from a general exchange having an ID sending function, the telephone number of the own station can be omitted.

The calling 21 (other station 21 (FIG. 2)) sends the predetermined data to the mobile station device 7 when the mobile station device 7 calls S.

When the mobile station device 7 is called, it registers the predetermined data in its memory device.

After that, the line goes from the general telephone to the general public network switching center without being disconnected, and then passes through the system switching center 22 (second
(hereinafter simply referred to as an exchange). During this time, the exchange 22 sends a ring tone (RBT) to the calling party's general telephone.

Next, the mobile station device 7 automatically makes a call using the predetermined data. This call is made by specifying a credit call, and the called party (the general telephone that made the call first) is billed.

By making the call, the mobile station device 7 and the switching center are connected via the call connection base station group 23, and as a result, the mobile station device 7 and the general telephone that originally made the call are connected on the same line. be done. This makes it possible to make a phone call.

As mentioned above, since the calling base station 21 uses the six-zone calling method, the calling base station 21 can receive calls regardless of where the mobile station device 7 is located, except in places where radio waves are difficult to reach, such as underground. It is possible to make a call and send predetermined data to the mobile station device 7.

On the other hand, the call connection base stations 23A, 23B, 23C, etc., which represent the call connection base station group 23, are arranged in a minimal zone, and the presence of the dead zone Xj is recognized.
The mobile station device 7 connects to base stations 23A, 23B, 23 for outgoing calls.
It is also possible that the user is located outside of C.'s service area, and in this case, even if an automatic call is made, the line cannot be connected.

Therefore, even if the mobile station device i
If the mobile station device 7 does not make a prompt call, the switching center determines that the operator of the mobile station device 7 is not working, or that the mobile station device 7 is “out of service area,” or that the mobile station device 7 is called by someone else. It is determined that the call is in progress with the telephone, and a talkie announcement to that effect is sent to the general telephone that made the call, and the connection is established when predetermined data is transmitted from the general telephone to the mobile station device 7. Additionally, the line between the general telephone set and the switching office is disconnected.

The predetermined data is held in the memory of the mobile station device 7, and when the mobile station device 7 moves into the service area of any base station for call connection in the group of base stations for call connection 23. The automatic call will then be made again. This connects the line.

FIG. 5 is a flowchart 1 showing the operation of the mobile station device 7. This process starts when the power switch of the moving field device 7 is turned on.

First, in step S1, it is determined whether the call switch is on. If the call switch is not on, in step S2, the calling base station 21 (
2), it is determined whether a call has been made, that is, whether a call has been received or not. If no call is received,
Return to step S1. That is, in this case, the mobile station device 7 is in a reception standby state.

When a call is received, in step S3, data such as the telephone number of the calling party dialed by the calling party, a credit card number for making a credit call, and a registered telephone number are transferred to the radio 4 or the telephone. 5 (FIG. 2).

Thereafter, in step S4, a ring tone sounds.

In step S5, it is determined whether or not the call switch is turned on. If the operator of the mobile station device 7 does not turn on the call switch, it is determined in step S6 whether or not a scheduled time has elapsed since the ringing tone. If the scheduled time has not elapsed, the process returns to step S4.

If the scheduled time has elapsed, in step S7, a message "Call" is displayed on the display device installed in the handset l-5B (Fig. 2) (character display on the display,
or display by lighting a lamp). After that, the process returns to step S1.

If it is determined in step S5 that the call switch is turned on, the process proceeds to step S1.
Move to 2. In this step 9 S12, it is determined whether or not an automatic call changeover switch is on, which specifies whether or not to make an automatic call when the call switch is turned on after receiving a call. The automatic call changeover switch is provided in the handset cell I-5B (FIG. 2).

If the automatic call switching switch is off, the process moves to step S22, which will be described later; if it is on, the process moves to step S22.
13.

In step S13, it is determined whether the radio wave condition is sufficient for communication, in other words, whether the field strength of the radio waves is sufficient.

If the electric field strength is not sufficient, in step S19, the display device provided in the handset 5B displays "out of range" (by text or lamp lighting), and in step S20, further displays "calling". It will be done. After that, the process returns to step S1.

If it is determined in step S13 that the electric field strength is sufficient for communication, the display of "out of range" is canceled in step S14.

0 In step S15, the data registered in the memory device in step S3, that is, the calling party's telephone number, the credit card number for credit calls, the registered telephone number, etc., are used to send information to the calling party. Make an automatic call. Note that, as described above, when making this call, credit calling is specified if necessary.

In step S16, the line between the calling side telephone and the mobile station device 7 is connected, and a call is made. and,
In step S17, it is determined whether or not the call has ended. If the call has not ended, the process returns to step 316.

If the call has ended, in step 318, the number registered in the memory device and used when making the call is
Communication data will be deleted. Thereafter, the line is disconnected and the process returns to step S1.

Now, in step S1, if it is determined that the call switch has been turned on, the process proceeds to step S11.
to move to.

In step S1l, it is determined whether data (data registered in step S3) exists in the memory device. If no data exists in the memory, the display of "calling" is canceled in step S21. Then, the process moves to step S22. Further, if a pig exists, the process is performed in step S
Proceed to step 12.

In step S22, it is determined whether the electric field strength is sufficient for communication. If not sufficient, step S2
In step 4, "out of service area" is displayed, and then the process returns to step S1.

If the electric field strength is sufficient for communication, the display of "out of range" is canceled in step S23.

Then, in step S25, the mobile station device 7
'I' indicates whether the dial was made by the operator of
If the dial is not dialed, the process returns to step S1.

If dialing has been performed, a call is made in step S26, and after the lines of the mobile station device 7 and the other party's telephone are connected, a call is made in step S27.

In step 328, it is determined whether the call has ended or not, and if it has not ended, the process goes to step S27, and if it has ended, the line is disconnected at step 11F, and then step S1
Return to

FIG. 6 is a flow cheat-1 showing the operation of the base station device consisting of the calling 2I (another station 21, this system switching center 22, and the calling connection other station group 23).

In FIG. 6, first in step S51, it is determined whether or not a call has been made to the mobile station device 7 using the system.

If a call is made, in step S52, data for identifying the telephone that made the call (hereinafter referred to as ID) and ID for identifying the mobile station device 7 dialed from the telephone are identified, Remember. Each of the IDs is identified from each dialed telephone number. This ID
may be the telephone number itself, and the 3 ID of the calling party's telephone may be data determined by a scanning device (not shown) of the general public network exchange.

In step S53, predetermined data, that is, data dialed from the telephone, the telephone number of the telephone itself, and if necessary, data such as a credit card number and registered telephone number are transmitted to the mobile station device 7. Ru.

In step S54, the line between the telephone set and the switching center is maintained without being disconnected.

In step S55, it is determined whether a call has been made to the telephone that previously made the call. In other words, the telephone ID stored in step S52,
ID of the destination phone of the mobile station device that made the automatic call
It is determined whether or not there is a match.

If no call has been made, in step 858;
It is determined whether the scheduled time has elapsed or not, and if the scheduled time n4 has not elapsed, the process returns to step S55.

If it is determined in step S55 that a call has been made, in step 856, the I and D of the mobile station device that made the call are connected to the telephone (where the line to the switching center is connected). It is determined whether the ID of the calling mobile station (telephone) and the calling mobile station match.

If they match, in step S77, the line from the switching center to the mobile station device is connected, and thereby all lines are connected.

If it is determined in step S78 that the call has ended, the line is disconnected in step S79, and the process returns to step S51.

If ID matching is not confirmed in step S56, a busy tone is transmitted to the mobile station device that made the call in step S57, and the process moves to step 858.

If it is detected in step 358 that the scheduled time has elapsed, then in step S59 the operator of the mobile station device 7 that made the call is absent, or the mobile station device 7 is outside the service area (“out of service area”). ), or that the mobile station device 7 is busy with another general telephone, is sent to the telephone that made the call in step S51. After that, the process moves to step S79.

If it is not determined in step S51 that a call has been made to the mobile station device 7, then in step S71 it is determined whether or not a call has been made from the mobile station device to another telephone using the system. I'll be separated. If the call is not made, the process returns to step S51.

When a call is made, in step S72, similarly to step S52, an FD for identifying the mobile station device and an ID for identifying the general telephone dialed by the mobile station device are identified. and remember.

Note that identification of the ID for specifying the mobile station device is generally performed by transmitting an ID for specifying the mobile station device 7 when making a call from the mobile station device 7.

In step S73, the line between the mobile station device 7 and the switching center is connected.

In step S74, it is determined whether or not the telephone that made the call is in a waiting state for connection.
In step 4, it is determined whether or not the telephone is the one that has been connected to the line of the exchange. In other words, it is determined whether the ID of the telephone that made the call is registered in step S52.

If it is not in the connection waiting state, that is, if the ID of the telephone that made the call is not registered in step S52, the process moves to step S77.

If it is in the connection waiting state, in step S75, the ID of the mobile station device that made the call matches the ID of the mobile station device called by the telephone (the line to the exchange or the telephone connected to the exchange). It is determined whether or not. If they match, the process moves to step S77.

If they do not match, the process moves to step S76, where a busy tone is sent to the mobile station device, and then returns to step S51.

In this way, communication as shown in FIG. 4 can be performed.

FIG. 1 is a functional block diagram of a mobile station device that performs the operations shown in FIG. In FIG. 1, the same reference numerals as in FIGS. 2 and 3 represent the same or equivalent parts.

In FIG. 1, the calling transceiver 2 and the field strength determining means 57 are connected to a power switch (not shown) of the mobile station device.
After turning on (switching on) the call switch 5
The other components are energized only by turning on the power switch.

That is, by turning on the power switch, the calling base station 2
1 (FIG. 2), and by turning on the call switch 56, it becomes possible to transmit to the call connection base station group 23.

First, when only the power switch is turned on and a call is made to the calling receiver 1, the calling party 8 receives predetermined data sent from the calling party, that is, the telephone number of the calling party's telephone, and the information for making a credit card call. The credit card number, registered telephone number, etc. are stored in the storage means 51. In particular, the buzzer 53 is energized and a ringing tone is generated.

When the predetermined data is stored in the storage means 51,
A signal indicating that data is stored from the storage means 51 is sent to the set terminal S of the timer 52 and the AND gate 6.
It is output to one input terminal of 1. This timer 52 is
By inputting a control signal to the set terminal S, it starts IT 1llll for a predetermined time, and outputs a signal Q after the measurement. This signal Q is transmitted to the buzzer 5 via an OR gate 63.
3, thereby stopping the energization of the buzzer 53. Further, the signal Q is outputted to the call display means 54 via the OR gate 60, thereby displaying "call".

When the call switch 56 is turned on by the operator of the mobile station device before the predetermined time period 1i1111 is completed by the timer 52, a control signal is sent to the buzzer 53 via the reset terminal R1 of the timer 52 and the OR gate 63. is output. As a result, the buzzer 53 is energized to p;':IL, but the timer 52 is reset, so the signal Q is not output, and the call display means 54 does not display "Call".

As described above, when the call switch 56 is turned on, the calling transmitter/receiver 2 and the boost strength determining means 57 are energized. The field strength determining means 57 detects whether the field strength of the radio waves received by the calling transceiver 2, that is, the radio waves constantly transmitted from the call connection base station group 23, is sufficient for communication. Then, it is determined whether the mobile station device is located within the service area of the call connection base station group 23.

When the electric power increase intensity is insufficient, the electric power increase intensity 'l'l+ determination means 57 sets the out-of-range display means 55 to ``1'' and displays "
In addition, a control signal is output to the other input terminal of the AND gate 61. In this case, a signal indicating that data is stored from the storage means 51 is output to one input terminal of the AND gate 61. If it is done manually,
The call display means 54 displays "call".

715,! 8 is sufficient for communication, the handset 5C is energized, a signal to that effect is input to the out-of-range display means 55, and the display of "out of range" by the display means 55 is canceled. Further, the signal is
It is output to the second input terminal. One of the data stored in the recording means 51 (predetermined data for 1 minute) and the output signal of the automatic call changeover switch 58 are also output to the input terminal of the AND gate 62. The call changeover switch 58 outputs a signal to the AND gate 62 when the switch 58 is turned on.

Therefore, when the electric field strength detected by the electric field strength determining means 57 is sufficient for communication, when the automatic call changeover switch 58 is turned on, and when the predetermined data for at least one communication is stored in the storage means 51. If so, the predetermined data for the one communication is output to the automatic calling means 59.

When a predetermined number of data for one communication is input, the automatic calling means 59 uses the data to automatically make a call. This call is made so that if it is necessary, it will be the relevant communication or a credit I/phone call. Further, this automatic call may be made in an on-hook state, or may be made after off-hook after the call switch 56 is turned on.

After the line is connected, a call is made using the handset 5C.

After the call has ended, a signal to that effect is output from the handset 5C or other means to the storage means 51. As a result, the data for one communication used for the automatic call is erased from the storage means 51.

When the storage means 51 runs out of data stored in the storage means 51, it outputs a signal to that effect to the call display means 54 and cancels the "recall" display.

If the electric field strength determination means 57 determines that the electric field strength is sufficient for communication, and the automatic call changeover switch 58 is not turned on, or the data is stored in the storage means 51. If not, automatic calling means 59 does not make an automatic call. In this case, a call can be made by dialing using the handset 5C.

Note that when the out-of-service area display means 55 is displaying "out of service area" and an attempt is made to dial using the handset 5C, a busy tone is further transmitted to the handset 5C. Also good.

FIG. 7 is a functional block diagram of a cross-ground station device that performs the operations shown in FIG. 6. In FIG. 7, the same reference numerals as in FIG. 2 represent the same or equivalent parts.

Note that the reference numeral 12 indicates a general public network switching center.

In FIG. 7, if the signal sent from the general telephones 11A to 11C is communication using the system and calls a mobile station device, the call determination means 82 performs the call determination, A line between the telephone and the connection means 81 of the base station device is maintained in the connection means 81.

Then, from the predetermined data sent from the telephone, an ID that specifies the telephone and the mobile station device to be called is identified and stored in the ID identification/storage means 83.

At the same time, the set terminal S of the timer 84 is energized, and the timer 84 starts measuring a predetermined time.

The predetermined data output from the telephone is sent from the calling base station 21 to a mobile station device (not shown).

When the timer 84 completes a predetermined period of time 11111, it energizes the connection means 81 to disconnect the line between the calling telephone and the connection means 81, and at the same time,
energizing the I-key guide means 85;

This talkie guide means 85 performs step S59 in FIG.
The l.-key guidance described above is sent to the telephone set using the ID stored in the ID identification/storage means 831.

Similarly, when a mobile station device calls another mobile station device, the paging signal received by the call connection base station group 23 is determined by the paging determining means 82, and the paging is performed by the connecting device 81. The line between the mobile station device and the connecting means 81 is connected, and at the same time, the set terminal S of the timer 84 is energized. Further, the required data sent from the mobile station device is sent via the calling base station 21, and the ID of each mobile station device on the calling side and the called side is also stored in the ID identification/storage means. 83.

Then, when the timer 84 finishes measuring the predetermined time, movement 1. When the line between the "men's clothing" and the connecting T stage 81 is disconnected, the 1-key guide means 85 is activated at Jl<.

Now, when the mobile station device that has received the call in this way makes an automatic call based on the received predetermined data, the call signal of the radio wave received via the call connection base station ff, 23 is determined by the call determination means 91, and is the ID of the mobile station device that made the call and the telephone to be connected, that is, the ID of the telephone that originally made the call (or other mobile station device); /Identified and stored in the storage means 92.

The comparison means 93 compares the ID stored in the ID identification/storage means 835 and the ID stored in the ID identification/storage means 92, and depending on the result, connects the connection means 81 and the busy tone generator. controlling means 94;

That is, this comparison means 93 is the ID identification/storage means 8
3, the ID of the telephone that made the initial call, and the ID of the telephone stored in the ID identification/storage means 92.
D, the ID of the mobile station device that made the call, which is stored in the ID identification/storage means 83;
I of the mobile station device stored in the ID identification/storage means 92
When D and D match, the connecting means 81 is controlled to connect the lines of the mobile station device and the telephone. At the same time, a control signal is output to the reset terminal R of the timer 84 to cancel time measurement by the timer 84.

Similarly, the ID corresponding to the ID of the telephone stored in the ID identification/storage means 92 is stored in the ID identification/storage means 83.
In the case where the telephone is not stored in the mobile station, the connection means 81 is controlled and the telephone After the mobile station device outputs a ring tone and goes off-hook, the lines of the mobile station device and the telephone device are connected. In the above case, when the telephone that made the call is in an off-hook state, the busy tone generating means 94 is activated to output a busy tone to the mobile station device.

Further, when the IDs of the telephones in the ID identification/storage means 83 and the ID identification/storage means 92 match,
Even when the IDs of the mobile station device do not match, the lines of the mobile station device and the telephone are not connected, and the busy name generating means 94 is sent to the mobile station device for (=1 minute). The telephone to be connected outputs a busy tone indicating that it is waiting for connection with another mobile station device.

Now, in the above description, the remote station equipment of the mobile communication system, which is composed of the calling base station 21, the switching center 22 for this system, and the calling connection (other station group 23), is :'+゛'s tracking exchange, such as the car phone system.
He said there was no change of heart about registering his location. This simplifies the configuration of the system, but in this case, of course, if the mobile station device moves out of the service area of the base station for calling and connecting during a call, the call will continue. Can not do it. Therefore, tracking exchange, location registration, etc. may be performed so that communication can be performed even when the user moves to an adjacent base station for calling connection.

Furthermore, although the mobile station device 7 has been described as being mounted on the mobile station device 8, the present invention is not particularly limited to this, and it goes without saying that the mobile station device 7 may be a mobile phone. The mobile station device of the present invention includes a radio 4, a telephone 5, and an antenna 6.
3j1 (the calling receiver ■ which occupies most of the volume and weight of the line machine 4 and the calling transceiver 2,
Since they are a receiver exclusively for calling and a transmitter/receiver for calling with low output used in extremely small zones, they can be made smaller and lighter. Therefore, the mobile station device can also be downsized and is suitable for use as a mobile phone.

Furthermore, although the description has been made assuming that the line is connected by credit card communication by automatic calling from the called mobile station device, it goes without saying that credit card phone call is not necessarily required.

In addition, when issuing a ++IP to the mobile station device 7 using this system, after creating a dial code that specifies that a call will be made using this system, a general public network exchange or the exchange for this system must be used. Step 1 of Atayal operation from station 22
・Guidance may be provided using the - key.

In addition, as shown in FIGS. 1 and 3, the mobile station device 7
has been described as having a paging receiver 1 and a calling transceiver 2, but if the frequencies of the received radio waves are matched, the function of the paging receiver 1 can also be used as the calling transceiver 2. It is possible to do so. However, the calling base station 21
Since the radio waves transmitted by the base station group 23 and the radio waves transmitted and received by the call connection base station group 23 have different purposes, a more effective system can be achieved by using frequency bands suitable for each of them. I can do it.

In other words, the radio waves transmitted from the calling receiver 21 use a lower frequency band that is suitable for reaching the mobile station device 9 by going inside buildings, etc., and are transmitted by the calling base station group 23. By using a higher frequency band for transmitting and receiving radio waves that allows for a large number of communication channels, incoming calls to the mobile station device can be performed more efficiently, and more communication lines can be set up, so for example, It is possible to set a larger number of subscribers without limiting communication time.

Furthermore, when a call is made, the line between the general telephone and the switching center 22 for this system remains connected, and after the mobile station device 7 that received the call makes an automatic call, all call lines are connected. However, after making a call, the line between the general telephone and the switching center 22 for this system is disconnected, the telephone that made the call waits in an off-hook state, and then the mobile station device 7 that received the call
Alternatively, all call lines may be connected after an automatic call is made.

(Effects of the invention) In the case of a call to a mobile station device, the calling side's data is transmitted via a base station dedicated to calls equipped with a large scene device, and the connection of the call line is recognized to have dead zones. Since the call connection is made from the mobile station device via the call connection base station group arranged in the minimum zone, the following effects are achieved.

(1) Even if it is acknowledged that there is a dead zone in the group of call connection base stations,
At least it becomes clear that there is an incoming call to the mobile station device, so if you move to a place where you can make a call and then make a call,
It becomes practically possible to receive and originate calls to the mobile station device.

Therefore, the number of call connection base stations can be reduced, and the configuration of the base station device side can be simplified.

(2) When the mobile station device is waiting for an incoming call, it is sometimes unnecessary to supply power to the calling transceiver, which saves battery power. In addition, since the output of the base unit 21 for call connection is small, the transmission output of the transmitter/receiver of the mobile station device can also be reduced. Therefore, the mobile station device can be made smaller.

(3) Since calls are made via a call connection station (a group of other stations) arranged in very few zones, it is possible to increase the number of subscribers by repeatedly using frequencies.
