DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a PHS will be described below with reference to the drawings. FIG. 1 shows the configuration of the entire system, wherein 1 is a digital public network, 2 is a center device that controls and manages the digital public network 1, and 3 is a database storing various information of the center device 2 (in FIG. ., 4, 4,... Are connected to the digital public network 1 and have a plurality of base stations (FIG. 1) attached to perform wireless communication with PHS terminal handsets existing in their respective areas. In the figure, reference numeral 6 denotes a “PBS”), reference numeral 6 denotes a terminal base unit fixedly disposed in the home 5 and connected to the digital public network 1, and reference numeral 7 denotes a pair with the terminal base unit 6 and used as a portable terminal unit It is.

FIG. 2 shows a circuit configuration inside the terminal slave unit 7, wherein an antenna 11 directly transmits and receives radio waves. The 1.9 MHz band high frequency signal received by the antenna 11 is input to the transmission / reception unit 12.

The transmitting / receiving unit 12 includes an antenna switch,
A high-frequency signal received by the antenna 11 is input to the frequency conversion unit via an antenna switch that is controlled to switch between transmission and reception.

In the receiving side circuit of this frequency conversion unit, PL
By mixing a local oscillation signal of a predetermined frequency output from the L synthesizer with a high frequency signal input via the antenna switch, the frequency is converted to an intermediate frequency signal of about 1 MHz and transmitted to the modem.

[0013] Further, in the transmitting side circuit of this frequency conversion unit,
Π / 4 shift QPSK (Quad) input from the modem
ratture Phase Shift Keyin
g: Four-phase phase shift keying) is mixed with a local oscillation signal of a predetermined frequency output from the PLL synthesizer to convert the frequency to a 1.9 GHz high frequency signal, and the above is converted via an antenna switch. Radiate from the antenna 11.

In the modem, the receiving-side circuit demodulates the intermediate frequency signal from the frequency conversion unit, separates the signal into orthogonal IQ signals, and transfers it to the next-stage communication control unit 13 as reception data comprising a digital data string. Then, the transmission side circuit creates IQ data from the data sequence transferred from the communication control unit 13, performs π / 4 shift QPSK, and sends out to the frequency conversion unit.

The communication control unit 13 performs data format processing at the time of a frame and at the time of a slot. At a receiving side circuit, at a predetermined timing, data of one slot is taken out of the received data sent from the modem of the transmitting / receiving unit 12, and After extracting a unique word (synchronization signal) from the data to synchronize the frames and descrambling the control data section and the audio data section, the control data is sent to the control section 18 described later, and the audio data is sent to the next. The data is transferred to the audio processing unit 14 of each stage.

In the transmission side circuit of the communication control unit 13, control data and the like are added to the voice data transferred from the voice processing unit 14, the data is scrambled, and then a Yonique word and the like are added. The transmission data is created, inserted into a predetermined slot in the frame at a predetermined timing, and transmitted to the modem of the transmission / reception unit 12.

The audio processing section 14 is composed of a speech codec section and a PCM codec section. The speech codec section performs compression / expansion processing of digital data, and its receiving side circuit has an ADPCM (Adaptive Diffie) transmitted from the communication control section 13.
rental Pulse Coded Modul
The audio signal (quantization bit number 4 bits × sampling frequency 8 kHz = 32 Kbps) converted to P
The data is expanded by decoding into a CM audio signal (quantization bit number 8 bits × sampling frequency 8 kHz = 64 Kbps) and transmitted to the PCM codec unit.

The transmitting side circuit of the speech codec unit compresses the data by encoding the PCM audio signal sent from the PCM codec unit into an ADPCM audio signal and sends the data to the communication control unit 13.

The PCM codec performs an analog / digital conversion process. The receiving side circuit performs D / A conversion of the PCM audio signal sent from the speech codec to obtain an analog audio signal. Loudspeaker 15 constituting the receiver is driven.

On the other hand, the transmitting side circuit of the PCM codec unit A / D converts an analog audio signal inputted by the microphone 16 which is paired with the speaker 15 and constitutes a transmitter, into a PCM audio signal. Output to the speech codec unit.

However, the display unit 17, the control unit 1 and the transmission / reception unit 12, the communication control unit 13 and the voice processing unit 14
8, a ROM 19, a RAM 20, and a base station identification signal storage unit (shown as “PBS-ID” in the figure) 21 are connected.

The display unit 17 is composed of, for example, a liquid crystal display panel and its driving circuit, and displays the telephone number of the destination to which the dial operation has been performed, the current time, the operating state at that time, and the like by characters, numbers, symbols, or the like.

The control unit 18 controls the overall operation of the apparatus according to a predetermined protocol in response to a key input from the key input unit 22. In particular, the transmission / reception unit 12, the communication control unit 13, and the voice processing unit 14 and various control signals.

The key input unit 22 has a dial key 22a for dial operation and a function key 22b for service operation to be described later, which is composed of "service", "position", "time" and "content".

The control unit 18 having received the key input from the key input unit 22 executes the operation program stored in the ROM 19 and stores appropriate control data necessary for operation control in the RAM.
The control operation is performed by successively accessing the data stored in the display unit 20 and the display unit 17 displays the display data.

The operation of the above configuration is as follows. FIG. 3 shows setting contents when first registering the types and contents of services when, for example, three kinds of services are provided when the mobile terminal 7 is used in a portable manner.

That is, here, as the three types of services, the home 5 in which the terminal base unit 6 corresponding to the terminal slave unit 7 is installed.
A “homecoming message” service that transfers a pre-registered voice message to the terminal base unit 6 when it comes nearby, and a “waiting report” that informs a specific partner when the terminal slave unit 7 arrives at the meeting place. "Self-notification" that informs the user using the terminal slave unit 7 that the service has arrived at a predetermined place.
Service shall be provided.

When the service registration shown in FIG. 3 is performed, the registration mode is set by first operating the "service" key of the function keys 22b of the key input unit 22, and then the dial key 22a for the "home message" service. After specifying the type of service by operating the number “1” key in the middle, the “2” key for the “waiting report” service, or the “3” key for the “self-reporting” service, the function is specified. Position setting using the "position" key of the keys 22b (step A1), time setting using the "time" key (step A2), and content setting using the "content" key (step A2) Step A3) is performed continuously.

FIG. 4 shows the contents of the position setting process in step A1. At first, the process waits for the "position" key to be operated (step B1), and confirms that the key has been operated. Then, it is determined whether or not the "position" key is operated again (step B2).

When there is an input by a key operation other than the "position" key, the key input data is temporarily taken in as the position data indicating the base station number of the specific area, temporarily buffered in the RAM 20 (step B3), and again. In step B2, the operation waits for the second operation of the "position" key.

If it is determined that the "position" key has been operated, then it is determined whether or not there is buffered input data.
It is determined whether or not an input by another key operation has been performed between the operation of the "position key" for the second time (step B4).

If it is determined that there is input data,
The buffered input data is set anew in the base station identification signal storage unit 21 as position data indicating the base station number of the specific area (step B5).

If it is determined in step B4 that there is no input data, the "position" key has been operated twice consecutively. The station number, that is, the base station number of the base station in the area where the station is located is directly set as position data in the base station identification signal storage unit 21 (step B).
6).

By performing the processing in step B5 or step B6, the position setting processing is completed, and the processing returns to the processing in FIG. By performing such a position setting process, the “homecoming message” service allows the RAM 20
The information indicating that the "home message" service has been registered is stored therein, and the "position" key is pressed twice consecutively when setting the service registration in the home 5 or in the same area as the home 5. Just by operating, the base station number of the area where the home 5 is located can be automatically registered in the base station identification signal storage unit 21. At this time, RA
In M20, information indicating that the registration of the "Home message" service has been performed is stored.

Further, when setting the "meeting notification" service or the "self-notification" service, the location or purpose of the meeting is determined by referring to a guidebook or the like issued by the contracted business operator. By operating the base station number of the area of the place to be operated with the numeric keys of the dial keys 22a, the base station identification signal storage unit 21 can be easily registered. At this time, information indicating that the “waiting notification” service or the “self notification” service has been registered is stored in the RAM 20 at the same time.

When the position setting in step A1 is completed, the process proceeds to time setting processing in step A2. That is, the time setting is performed by operating the "time" key in the function keys 22b, and subsequently operating the time data for limiting the time zone for receiving the service by operating the numeric keys or the like in the dial keys 22a. Input time data is stored in RAM once
20.

By limiting the time for receiving the service by performing such time setting processing, the "homecoming message" service may be erroneously set by turning on the operation power of the terminal slave unit 7 at a time other than the time of returning home, for example, when going to work. To prevent a homecoming message from being sent home, and the "waiting notification" service to inadvertently promptly notify the other party if you unexpectedly arrive early at a meeting place. Can be prevented.

If the time data is not set by operating the "time" key, the time for receiving the service is not particularly limited. When the time setting in step A2 is completed, step A
The process proceeds to the content setting process of No. 3. FIG. 5 shows the contents of the process of setting the contents in step A3. At first, the process waits for the operation of the "contents" key of the function keys 22b (step C1), and confirms that the operation has been performed. Then, it is determined whether the type of service to be set next is the “home message” service, the “waiting notification” service, or the “self notification” service (step C).
2).

This is because, following the operation of the "service" key at the beginning of the setting, the numeric key "1" in the dial keys 22a is set.
The determination is made based on which one of the operations “.about.3” has been operated. If the number key "1" in the dial keys 22a is operated after the operation of the "service" key at the beginning of the setting, the setting is for the "home message" service. 7 communicates with the center device 2 via the digital public network 1 (step C3).
The center device stores the base station number of the base station in the area where the home 5 is stored in the base station identification signal storage unit 21, the code "1" indicating the "homecoming message" service, the time data stored in the RAM 20 by the time setting, and the like. 2 and a voice message of a message for returning home is input by the microphone 16 as a transmitter in accordance with a message input instruction from the center device 2 (step C4).

If the numeric key "2" in the dial keys 22a is operated following the operation of the "service" key at the beginning of the above setting, the "waiting notification" service is set. Then, the telephone number of the waiting party to be notified is input using the dial key 22a (step C5). Then, the base station identification signal storage unit is transmitted from the terminal slave unit 7 to the center device 2 via the digital public network 1. The base station number of the base station in the area where the waiting place is stored in 21, the code “2” indicating the “waiting notification” service, the time data stored in the RAM 20 according to the time setting, and the like are transferred to the center device 2. (Step C6).

Further, following the operation of the "service" key at the beginning of the setting, the numeral key "3" in the dial keys 22a is set.
Has been operated, it means that the setting is for the "self-notification" service, so that processing is not particularly performed on the center device 2 or the like.

However, after performing the processing of step C4 when setting the "home message" service, the processing proceeds to step C6 when setting the "queue notification" service.
After performing the processing of (1) or after performing no processing when setting the “self-notification” service, the registration data is determined (step C7).
Thus, the content setting process of FIG. 5 is completed, and the service registration process of FIG. 3 is also completed.

FIG. 6 shows an example of a file stored in the database 3 of the center apparatus 2 by the service registration process. Here, the number "0001"
Is a base station number "X-1".
The "home message" service is registered with the time limit of "after 18:00" for the terminal parent device 6 in the area in charge of the base station 4 indicated by "."
This indicates that the voice message data of "return in minutes" is registered at the address position indicated by "P1" in the database 3.

At the same time, when the terminal slave unit 7 enters the service area of the base station 4 indicated by the base station number "Y-1" which is a meeting place, the other party's telephone number "1010"
It also shows that the "waiting notification" service for "" has been registered for a limited time of "12:00".

The time limitation of “12:00” means that the terminal slave unit 7 enters the area of the base station 4 indicated by the base station number “Y-1” at the time of “12:00”. This means calling the other party's phone number only when the call is made.

Next, a description will be given of processing contents at the time of actual operation after the above-described service registration is performed. FIG. 7 shows the operation of the terminal device 7. As shown in the figure, the terminal slave unit 7 has received the information indicating whether or not the base station number radiating the radio wave has changed in the RAM 20 by the base station identification signal in the received radio wave at the time of operation. The determination is always made by comparing with the base station number (step D1).

When it is determined that the base station number has changed, it is then determined whether or not the new base station number matches the base station number stored in the base station identification signal storage section 21 (step D2).

If they do not match, no processing is performed, but if they do match, then the information indicating the type of registered service stored in the RAM 20 is referred to.
That is the "homecoming message" service, "waiting notification"
It is determined whether the service is the service or the "self-notification" service (step D3).

When the service type is the “home message” service or the “waiting notification” service, the terminal handset 7 calls the center device 2 via the base station 4 and the digital public network 1. And its own phone number and its own handset number (ID), for example, "0"
001 ”(step D5), and the process ends.

If the type of service registered in step D3 is the "self-notification" service, the terminal slave unit 7 sounds an alarm and enters the area of the registered base station number. To the user (step D
4) This ends the process.

FIG. 8 shows an operation on the side of the center apparatus 2 corresponding to the transmission operation of the terminal slave unit 7 in step D5 of FIG. The center device 2 constantly determines whether there is a call from the terminal device 7 (step E).
1).

If it is determined that a call has been made, then a corresponding file as shown in FIG. 6 is searched from the database 3 using the telephone number and the handset number (step E2), and the type of the registered service Is the "home message" service or the "waiting notification" service (step E3).

If the type of service is determined to be the "home message" service, the center device 2 next refers to the time limit column of the corresponding part of the file, and the time at that point is within the limited time. Is determined (step E4).

If the time does not correspond to the time limit, the service is not required, so that no processing is performed as it is. However, if it does, the voice message data registered at the address position indicated in the attached column of the file is used. Is read, and a message is converted to analog voice and transmitted after securing a call with the corresponding terminal master unit 6 in the home 5 (step E).
5) After that, the call is stopped, and this process is completed.

If it is determined in step E3 that the service type is the "queue message" service, the center device 2 also refers to the time limit column of the corresponding portion of the file, and at that time, It is determined whether or not the time is within the limited time (step E6).

If the time does not correspond to the time limit, no processing is performed as it is not necessary to perform the service, but if it does, the corresponding party is called by the telephone number in the call destination column of the file with an alarm sound. The process is notified (step E7), and the process is completed.

In the example shown in FIG. 6, both the "home message" service and the "waiting notification" service are registered in the file.
The base station identification signal storage unit 21 also stores the base station number in the area where the home 5 is located and the base station number in the area where the meeting place is located.

In the above embodiment, the "home message"
Although the description has been made assuming that the voice message is registered in the service, the present invention is not limited to this, and the message may be a text message, or may be notified by a specific alarm sound.
