[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, a handset for a mobile phone system, and a terminal for a pager system, which constitute the mobile phone.

0002

2. Description of the Related Art Car telephones or mobile telephones are becoming popular as wireless telephone systems. In this wireless telephone system, a handset can move from one base station's service area (base station area) to another base station's service area while making a call.

[0003] However, in order to realize such a function, the base station must always manage or know the current location of each slave unit. For this reason, the base stations must be connected to each other by computers, making the base station system complex and large-scale.

[0004] Furthermore, since the base station manages the slave units,
The number of slave units per base station is limited. Furthermore, in order to reliably achieve the above-mentioned functions, the transmission output of the handset must be relatively large, for example, 0.5 to 1W, which may shorten the battery life or increase the size and weight of the handset. I end up doing something like that.

[0005] Therefore, a digital cordless telephone system is being considered as a next generation radio telephone system for such radio telephone systems. In this digital cordless telephone system, the base station does not, in principle, manage handsets. Therefore, although it is possible to make calls from the handset, calls cannot be received to the handset. When an incoming call is required, by performing a predetermined key operation, the handset registers with the base station in advance that it is in the service area of that base station.

[0006] Furthermore, since the base station does not manage the handset, the handset cannot move from the service area of one base station to the service area of another base station while making a call; You can only move within the service area. This service area has a radius of 200
It is about m.

[0007] In other words, the digital cordless telephone system is similar to a wireless public telephone.

[0008] In the digital cordless telephone system, the base station does not, in principle, need to manage slave units, so it can be configured with only a transmitter/receiver and a switch, and the base station can be greatly simplified. .

[0009] Furthermore, since the handset is used near the base station and is not used while moving between different service areas,
The transmission output of the handset can be reduced to, for example, 0.1 W, and therefore the battery life can be extended. Furthermore, the handset can be made as small and lightweight as a notebook.

However, as mentioned above, in digital cordless telephones, calls are mainly made from the handset, and the handset cannot receive calls in principle. If you absolutely need to receive a call, you need to register with the base station in advance, and if you move to a different service area, you need to re-register. However, such registration is cumbersome. Moreover, the service area is narrow, with a radius of about 200 m, and the user cannot tell whether the service area has changed when moving, so this is not practical for people who frequently change locations, such as salesmen.

[0011] Therefore, in order to be able to receive calls from anywhere, a handset of a digital cordless telephone system,
It is conceivable to use it in combination with a pager system terminal (so-called pager). In other words, if this is done, a call can be made using the handset of the digital cordless telephone, and an incoming call (ring) can be recognized from the terminal of the pager system. In this case, since the pager system is originally intended to notify of incoming calls, the service area is wide and there is no need to register one's location in advance.

0012

[Problem to be Solved by the Invention] However, when using the handset of a digital cordless telephone system and the terminal of a pager system together, the user must carry both the handset and the terminal. However, it is inconvenient.

[0013] Furthermore, in the case of a pager terminal that can display the telephone number of the calling party when a call is received, when a call is made from the handset to reply to the incoming call, the telephone number displayed on the pager terminal The number must be entered using the dial keys on the handset, which is inconvenient.

The present invention aims to solve these problems.

[0015]

[Means for Solving the Problems] Therefore, in the present invention, if the reference numerals of each part correspond to the embodiments described later, the handset 1 of a mobile phone system mainly used for making calls to other telephones can be , and a terminal 6 of a pager system that receives calls from other telephones to form a mobile phone, and the handset 1 includes a transmitter 11, a receiver 12,
A transmitting/receiving circuit 15 for accessing the audio signal from the transmitter 11 and the audio signal supplied to the receiver 12 with the base station via radio waves, a first connector 50, a memory 23, and a terminal 6. A storage section 100 is provided in which the terminal device 6 is set, a second connector 80 is provided in the terminal device 6, and a second connector 80 is provided in the terminal device 6.
When the terminal 6 is set in the storage section 100, the first connector 50 and the second connector 80 are connected, and when the terminal 6 receives a call in this set state, the terminal 6 is The telephone number data TELD sent to the device 6 is imported from the terminal device 6 to the handset 1 through the second connector 80 and the first connector 50, written into the memory 23, and the written data T
A call is made to the telephone number indicated by the ELD.

[0016]

[Operation] When there is a call from another telephone, the call is accepted by the terminal 6, and the data TELD of the telephone number transmitted at the time of the call is sent from the terminal 6 to the handset 1, and the call is received by the terminal 6. Handset 1 for the number
A call is made from.

[0017]

In the handset 1, 10 is a communication circuit, 11 is a transmitter, 12 is a receiver, 13 is an audio codec circuit, 14 is a TDD control circuit, and 15 is a transmitting/receiving circuit. Then, the audio signal from the transmitter 11 is supplied to the audio codec circuit 13 where it is A/D converted from an analog signal to a digital signal, the digital signal is bit compressed, and the output signal is sent to the TDD control circuit 13. control data required for communication with the base station is added and time axis compression is performed for transmission in the TDD method. The output signal of the TDD control circuit 14 is then supplied to the transmitting/receiving circuit 15 and converted into a transmitting signal during the period of the transmitting slot, for example, a quadrature modulated signal, and this transmitting signal is supplied to the transmitting/receiving antenna 16 for the period of the transmitting slot. is sent to the base station every time.

[0019] Also, a signal is transmitted from the base station every reception slot period, and this transmission signal is transmitted to the antenna 1.
6, this received signal is supplied to the transmitting/receiving circuit 15 to demodulate the original baseband signal, this demodulated signal is supplied to the TDD control circuit 14 to extract the control data, and the reception signal in the TDD system is The time axis is expanded for this purpose. The output signal of the TDD control circuit 14 is then supplied to the audio codec circuit 13 where it undergoes bit expansion and D/A conversion to extract the original audio signal, which is then supplied to the receiver 12.

[0020] Therefore, the handset 1 can communicate with other telephones through the base station.

Further, in the slave device 1, 20 is a system controller composed of a microcomputer;
31 is an LCD that displays various information, 32 is a key such as a dial key, and 33 is an R on which an identification code is written.
It's OM.

FIG. 2 shows a specific example of the system controller 20, in which 21 is a CPU, 22 is a ROM in which various programs are written, 23 is a RAM for a work area, and 24 is a CPU.
-28 are input/output ports, and these memories 22, 23, ports 24-28, and ROM 33 for identification code are connected to the CPU 21 through a system bus 29. Although not shown, the audio codec circuit 13, TDD
Control circuit 14, transmitting/receiving circuit 15, LCD 31 and key 3
2 are connected to the system bus 29 through respective interface circuits.

Furthermore, 19 is a power supply battery, the output end of which is connected to the power supply line of the system controller 20 through the emitter-collector of a transistor 41, and the base of the transistor 41 is connected to the negative output of the flip-flop 47! Connected to Q. This flip-flop 47
is an RS flip-flop whose reset input R is connected to the output port 26. Furthermore, the output end of the battery 19 is connected to the power line of the communication circuit 10 through the switch circuit 42, and its control signal is supplied to the switch circuit 42 from the output port 28.

Further, 43 is a talk key composed of a non-locking type normally open switch, 48 is an RS flip-flop, which is used to hold the pressed key 43, and its output Q is It is connected to the input port 27. Then, the voltage of the battery 19 is changed to the inverter 44,
Buffer 45, OR circuit 46 and flip-flop 47
, 48 as their operating voltage.

Furthermore, 50 is a connection connector, which has first to third contacts 51 to 53, the contact 51 is connected to the input port 48 through the buffer 48, and the second contact 52 is connected to the buffer 45 and the input port 48. It is connected to a set input S of a flip-flop 47 through an OR circuit 46. Note that the contact 53 is a ground contact.

On the other hand, in the terminal 6 shown in FIG. 1, 62 is a receiving circuit, 63 is a ROM in which an identification code is written,
64 is an LCD that displays the calling party's telephone number, etc.;
5 is a ringer for calling, and 70 is a system controller composed of a microcomputer. In addition,
The identification code of the ROM 63 is an identification code unique to the terminal 6 and is independent of the identification code of the ROM 33.

Furthermore, 80 is a connection connector, and this connector 80 has first to third contacts 81 to 83, and when the terminal device 6 is combined with the slave device 1, the contacts 81 to 83 are connected to the connector 50. These are connected to the contacts 51 to 53, respectively. Although not shown in the figure, the contacts 81 and 82 are connected to the output port of the system controller 70.
This outputs a predetermined signal, which will be described later.

For example, as shown in FIG. 3, the entire terminal device 6 is constructed in the form of a card. Further, the handset 1 has a storage portion for storing the card-shaped terminal 6, for example, a slot 100 into which the terminal 6 is inserted, and when the terminal 6 is inserted into the slot 100, the connector 80 The contacts 81 to 83 of the connector 50 are the contacts 51 to 83 of the connector 50.
53, respectively.

[Standby state] In this case, as will be clear from the description below, since the flip-flops 47 and 48 have been reset, the operating voltage is not supplied to the communication circuit 10 and the system controller 20, that is, , handset 1 is in a power-off state.

[Normal call by handset] This is a call made by handset 1.
This is a case where a normal call is made. Furthermore, at this time,
The terminal device 6 may or may not be set in the slave device 1.

That is, when making a normal call using the handset 1, when the handset 1 is in standby mode, the talk key 4 is pressed.
Press 3. Then, the output of the key 43 is supplied as a set input to the flip-flop 48 through the inverter 44, so the output Q of the flip-flop 48 changes from "0" to "1", and the input of the input port 27 changes from "0" to "1". 1
” becomes.

Furthermore, since the output of the key 43 is supplied as a set input to the flip-flop 47 through the inverter 44 and the OR circuit 46, the negative output of the flip-flop 47! Q changes from "1" to "0". Hence this negative output! Q causes the transistor 41 to turn on from off, and the voltage of the battery 19 is supplied to the system controller 20 through the transistor 41 as its operating voltage.

When the operating voltage is supplied to the system controller 20, a power-on reset circuit (not shown) applies a power-on reset to the system controller 20, and the RO
Execution of the program M22 is started. In this case, when the key 43 is pressed, the input of the port 27 is "1", so the output of the port 28 causes the switch circuit 4 to
2 is turned on, and therefore the voltage of the battery 19 is also supplied to the communication circuit 10 through the switch circuit 42 as its operating voltage. In this way, when in standby mode, key 4
When 3 is pressed, power is supplied to all circuits of handset 1.

When power is supplied to all the circuits of handset 1, system controller 20 performs the same call processing as in the conventional digital cordless telephone system. That is, predetermined control data is accessed between the handset 1 and the base station through the communication circuit 10, and a communication channel is opened between the handset 1 and the base station. Therefore, when the telephone number of the other party is entered using the key 32, this is notified to the base station and the other party's telephone number is called.If the other party answers the call, the user can talk to the other party as described above. Note that at this time, the ROM
33 identification codes are transmitted to the base station and used to identify users who are subject to billing.

[Ending a call on the handset] When the call is ended, when the talk key 43 is pressed, the key output is taken into the system controller 20 through the inverter 44 and the input port 25.
It is determined that the key 43 was pressed to end the call. As a result, the system controller 20 executes a predetermined call termination process between the handset 1 and the base station, and then the switch circuit 42 is turned off by the output of the port 28, and the power of the call circuit 10 is turned off. Furthermore, the output from port 26 resets flip-flops 47 and 48. Therefore, the negative output of flip-flop 47! Q is set to "1", the transistor 41 is turned off, and the power to the system controller 20 is also turned off.

Thus, when the key 43 is pressed during a call, the call is terminated and the power to the call circuit 10 and the system controller 20 is turned off. Also, flip-flop 47
, 48 are in a reset state. That is, the handset 1 enters the above-mentioned standby state.

[Normal Call at Terminal] This is a case where a call is made while the terminal 6 is being used alone without being set as the handset 1.

In this case, the operation of the terminal 6 is the same as that of the terminal of a conventional pager system. That is, in the terminal 6, when a signal indicating an incoming call is transmitted from the base station of the pager system, this signal is received by the antenna 61 and supplied to the receiving circuit 62, where it receives data such as an identification code and a telephone number. is extracted, and its identification code is compared with the identification code of the ROM 63 in the system controller 70. If the two do not match, the signal from that base station is ignored.

However, when the two match, the ringer 65 is driven by the system controller 70, and the ringer 65 is notified that there is a call, and the telephone number of the calling party (the telephone number of the other party) is sent along with the identification code. data is supplied to the LCD 64, and the other party's telephone number is displayed on the LCD 64. Therefore, the user of this terminal 6 knows that he/she is being called by the other party having the displayed telephone number.

[Call When a Terminal is Set as a Handset] This is a case where a call is made to the terminal 6 when the terminal 6 is set to one handset.

That is, the terminal device 6 is in the slot 1 of the slave device 1.
00, its contacts 81 to 83 are connected to contacts 51 to 53 of the handset 1. and,
In such a state, when a call is made to the terminal device 6, the system controller 70 executes the above-described call operation or processing.

At this time, when the identification code transmitted from the base station matches the identification code in the ROM 63, the output from the LCD 64 and the ringer 65 is executed as described above, and the system controller 70 displays the As shown in 4A, the signal WK is activated at time t1 when a match is recognized.
UP is formed, and this signal WKUP is output to the contact 82 (this signal WKUP is also output when the terminal 6 is used alone).

Then, this signal WKUP is transmitted through the contact 82→
Since it is supplied as a set input to the flip-flop 47 through the signal line of the contact 52 → buffer 45 → OR circuit 46, the negative output of the flip-flop 47! Q is “1”
” to “0”. Therefore, this negative output !Q turns the transistor 41 from off to on, and at time t1
The voltage of the battery 19 is supplied to the system controller 20 through the transistor 41 as its operating voltage.

When the operating voltage is supplied to the system controller 20, the power-on reset circuit applies a power-on reset to the system controller 20, starts executing the program in the ROM 22, and waits for input from the port 24. Also, in this case, the flip-flop 48 remains reset and the input to port 27 is "0", so
The switch circuit 42 remains off, and the communication circuit 10 remains without operating voltage.

Next, at time t2 after a predetermined period of time Δt from time t1, that is, when the system controller 20 is waiting for an input, as shown in FIG. 4B, in the terminal 6,
Data TELD of the calling party's telephone number transmitted from the base station is serially output from the system controller 70 to the contact 81. Note that this signal TELD is 1 of the telephone number.
For example, each digit is an 8-bit JIS code, and as shown in FIG. 4C with an enlarged time axis, RS-23
2C, and is output in units of one digit of the telephone number (this signal TELD is also output when the terminal 6 is used alone).

Then, this signal WKUP is transmitted through the contact 81→
It is supplied to the input port 24 through the contact 51 → buffer 48 signal line, is taken into the system controller 20, and is stored in the RAM.
At the same time, the written telephone number data TELD is supplied to the LCD 31, and the
The telephone number of the calling party is displayed at 31. Also,
At this time, in the terminal 6, the ringer 65 is driven to announce the call. Therefore, the user
You can see that you are being called by the person whose phone number is displayed on the LCD 31.

Then, when the talk key 43 is pressed, the key output is passed through the inverter 44 to the flip-flop 48.
Since the input signal is supplied as a set input to the input port 27, the input of the input port 27 changes from "0" to "1". Then, output port 2
The switch circuit 42 is turned on by the output of 8, and the operating voltage is supplied to the communication circuit 10, and at the same time, call processing is performed and a communication channel is opened with the base station. Subsequently, data TELD of the telephone number of the calling party is read from the RAM 23, and this data TELD is notified to the base station. Therefore, when the other party's phone is called through the base station and the other party answers the call, the user can talk to the other party as described above.

[0048] Even when a call is made in this manner, if the talk key 43 is pressed again, the above-described call termination process is performed and the call goes into a standby state.

Thus, according to the present invention, it is possible to make and receive calls, but in this case, especially according to the present invention, the handset 1 and the terminal 6 are combined into one mobile phone. This makes it easier to carry.

Furthermore, when there is an incoming call (ringing), handset 1 receives data T of the telephone number of the calling party from terminal 6.
In addition to receiving the ELD, the received data TE
Since the call is automatically made to the party indicated by the LD, there is no need to input the telephone number of the calling party displayed on the LCD 64 of the terminal 6 using the key 32, and the number of calls is greatly reduced. This makes it easier to enter phone numbers and prevents phone number input errors.

Furthermore, even if handset 1 is primarily responsible for making calls,
When a call arrives, it is accepted by the terminal 6 of the pager system, and since the service area of the pager system is sufficiently wide, there is no need to register one's location with the base station in order to receive a call, and it can be used as a normal mobile phone. It can be used like a slave unit of the system.

Furthermore, the terminal 6 can be removed from the handset 1, and the terminal 6 or the handset 1 can be used alone. Or handset 1 and terminal 6
and can be purchased separately if necessary.

Note that in FIG. 3, the terminal device 6 is connected to the slave device 1.
In this case, the entire terminal device 6 is built into the handset 1 by inserting it into the slot 100 of the handset 1. For example, by providing a recess in the handset 1 as a storage section and setting the terminal device 6 in this recess, the terminal device 6 can be inserted into the handset 1. A part of the device 6, for example the LCD 64, may be exposed to the outside of the handset 1 so that it can be seen.

[0054]

According to the present invention, the handset 1 and the terminal 6 are combined into one mobile phone, making it easy to carry.

[0055] Furthermore, when there is an incoming call (ringing), handset 1 receives data T of the telephone number of the calling party from terminal 6.
In addition to receiving the ELD, the received data TE
Since the call is automatically made to the party indicated by the LD, there is no need to input the telephone number of the calling party displayed on the LCD 64 of the terminal 6 using the key 32, and the number of calls is greatly reduced. This makes it easier to enter phone numbers and prevents phone number input errors.

Furthermore, even if handset 1 is primarily responsible for making calls,
When a call arrives, it is accepted by the terminal 6 of the pager system, and since the service area of the pager system is sufficiently wide, there is no need to register one's location with the base station in order to receive a call, and it can be used as a normal mobile phone. It can be used like a slave unit of the system.

Furthermore, the terminal device 6 can be removed from the handset 1, and the terminal device 6 or the handset 1 can be used alone. Or handset 1 and terminal 6
and can be purchased separately if necessary.
