Abstract

PROBLEM TO BE SOLVED: To conduct a speech by the intention of a caller by informing the caller that a called party reaching a speech available state to prevent unreasonableness that the execution of the speech is left for the called party because the speech available state of the called party having been disabled of the speech because of residence of the called party at the outside of a service zone is not informed of the called party but a fact of the arrival of an incoming call from the caller is reported to the called party. SOLUTION: In the extension reservation method for the PHS private branch exchange, a caller PHS makes a dialing to a called party PHS when the called party PHS is resident at the outside of a service zone of the PHS private branch exchange or power is interrupted (steps 101-105). When the called party PHS enters the service zone of the PHS private branch exchange or the power is applied and makes position registration to the PHS private branch exchange (steps 107-109), the method informs the caller PHS of the called party PHS reaching a speech available state (step 111).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reserving an extension of a PHS private branch exchange and a private branch exchange for the PHS using the same, and particularly when the PHS is located outside the area of the PHS private branch exchange or in a power-off state. And a PHS private branch exchange using the method.

[0002]

2. Description of the Related Art Some PHS private branch exchanges have a so-called extension reservation function. This extension reservation function is used when one PHS makes a call to another PHS, and if the PHS of the called party is in a call and cannot be called, the calling of the called PHS is terminated and then the calling party is called. This is a service that sounds the ringer of the PHS to notify that the PHS on the receiving side can be called. Note that when the PHS on the calling side makes a call to the PHS on the called side and the PHS on the called side cannot call, it is possible to set whether or not the caller uses the extension reservation function. However, the PHS on the receiving side
If the user goes out of the service area of the PHS private branch exchange or is turned off, not only the calling PHS cannot make a call, but also the extension reservation cannot be set.

In order to solve such inconvenience, for example, a device for storing a caller number is provided in an automobile telephone exchange system, and when a mobile terminal is out of the service area or the power is cut off, a call to the mobile terminal is issued. In some cases, a caller number is stored, and the stored caller number is displayed on the mobile terminal when the mobile terminal is turned on or enters a service area so that a call can be made. 63-87030). As a result, the user of the mobile terminal can immediately know the number of the caller when the out of service area or the call failure due to power outage is resolved.

[0004]

However, in the above-mentioned mobile telephone switching system, when the called mobile terminal becomes available for calling, only the caller number is displayed on the mobile terminal. The side cannot know whether or not the mobile terminal can be called. For this reason, whether or not a call is made later between the two parties is left to the callee's will, and even if the caller wants to call immediately, the callee does not always contact immediately. Failure may occur.

[0005] Further, when the mobile terminal becomes available for calling, only the calling party number is displayed on the mobile terminal. Therefore, if the called party does not confirm the display when the mobile terminal becomes available for calling, the call will not be made. I don't know what happened. In particular, since the mobile terminal does not perform any special operation when entering the service area, the calling party number may be displayed without the recipient's knowledge.

[0006] These are problems in the mobile telephone exchange system, but the same situation can occur in the extension reservation function in the PHS private branch exchange. For this reason, the PHS
There is a demand for an extension reservation function that enables a caller to make a call quickly with the intention of a caller when a call can be made.

Accordingly, the present invention provides an extension reservation method for a PHS private branch exchange which prevents a situation where a caller does not know a caller's PHS even if the caller's PHS can be called, and a PHS private branch using the same. It is intended to provide an exchange.

[0008]

As a technical means for achieving the above object, a method for reserving an extension of a PHS private branch exchange according to the present invention is provided when one PHS transmits a call to another PHS. If the called PHS is in a call and cannot be called, in the extension reservation method for a single PHS private branch exchange that informs the calling PHS after the called PHS can be called, the called PHS is PH
When the transmitting side PHS makes a call to the receiving side PHS when it is located outside the service area of the S private branch exchange or in a power-off state, the receiving side PHS enters the service area of the PHS private branch exchange, and When a location is registered in the PHS private branch exchange with the PHS, the originating PHS is informed that the receiving side PHS is ready to talk.

A PHS private branch exchange that uses the extension reservation method for a PHS private branch exchange according to the fourth aspect of the present invention is configured such that when one PHS transmits a call to another PHS, the called PHS is busy. If the call cannot be made in the PHS private branch exchange having an extension reservation means for notifying the calling PHS that the called PHS can be called after the called PHS becomes available, the called PHS is replaced with the PHS private exchange. When the transmitting side PHS makes a call to the receiving side PHS while being out of the service area or in a power-off state, the receiving side PHS enters the service area of the PHS private branch exchange or turns on the power, and When the location registration is performed with the PHS private branch exchange, the extension reserving means informs the calling side PHS that the called side PHS is ready to talk. It is characterized.

That is, when one PHS sends a call to another PHS, if the called PHS cannot be called during a telephone call even if the called PHS is powered on within the PHS private branch exchange, After the call ends and the call can be called, the calling PHS is notified that the called PHS can talk. This allows the caller to call the PHS
You can make a call to make a call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for reserving an extension of a PHS private branch exchange according to the present invention and a PHS private branch exchange utilizing the same will now be described in detail with reference to the preferred embodiments shown in the drawings. 1 to 3 show the P according to the present invention.
1 shows an embodiment of a private branch exchange 10 for HS.

As shown in FIG. 2, the PHS private branch exchange 10
The TDSW includes a TDSW 12, a central control unit 14, a storage device 16, a radio base station 18, and PHSs 20 and 22. This PHS private branch exchange 10 is independent, and one PHS 20 is replaced by another PHS 22.
If the called PHS 22 is in a call and cannot be called when a call is made to the calling party, an extension reservation means for notifying the calling PHS 20 of the fact that the called PHS 22 can be called is provided. Here, the terms “originating side” and “incoming side” are relative positions in a certain call,
Outgoing call and incoming call can be executed with one PHS.

The extension reservation means in the PHS private branch exchange 10 is such that the receiving side PHS 22
When the transmitting-side PHS 20 makes a call to the receiving-side PHS 22 when the transmitting-side PHS 20 is located outside the service area O of the area 26 or when the power is off, the receiving-side PHS 22 is in the service area I
The PHS 20 informs the calling side PHS 20 that the receiving side PHS 22 is ready to talk when the power is turned on or the power is turned on and the location is registered in the PHS private branch exchange 10. Therefore, when one PHS 20 makes a call to another PHS 22, even if the called PHS 22 is located outside the service area of the PHS private branch exchange 10 or is in a power-off state and cannot talk, the called P
When the HS 22 registers the location in the PHS private branch exchange 10 again, the calling side PHS 20 is notified that the called side PHS 22 is ready to talk, so that the caller can immediately call the called side PHS 22 and start talking. It can be carried out.

When notifying the transmitting side PHS 20 that the receiving side PHS 22 is in a communication enabled state, the transmitting side
The HS20 ringer sounds. For this reason, even if the caller does not always look at the PHS 20, he can recognize that the called side PHS 22 is in a callable state.

The extension reservation means is constituted by a computer. The computer includes, for example, a central control unit 14 that executes various arithmetic processes, and a RAM or RO that stores programs and data necessary for executing the arithmetic processes.
A main storage device such as M, various interfaces such as input / output ports, and a hard disk drive device for storing a program for realizing the extension reservation means and various files and data necessary for executing the processing; Generally, an input / output device for inputting data and necessary commands and outputting a result processed by the central processing controller 14 is provided. In the present embodiment, the storage device 16 corresponds to a main storage device or a hard disk drive. The extension reservation means is not limited to a computer and may be an electric circuit such as a sequence circuit.

In the storage device 16, an extension memory 24 corresponding to each of the PHSs 20, 22 is set as shown in FIG. The extension memory 24 stores the corresponding PHSs 20, 22
Extension presence / absence data 24a for recording the presence / absence of an extension reservation when the PHS is set to the receiving side, the PHS number data 24b for which the extension reservation was made for this PHS, and the PHS private branch exchange 10
And location registration data 24c.

On the other hand, the configuration and operation of the PHS private branch exchange 10 excluding the extension reservation means are the same as those of the existing one,
Detailed description is omitted.

The procedure for executing the extension reservation method by the extension reservation means of the PHS private branch exchange 10 will be described with reference to the time chart shown in FIG.

It is assumed that the receiving side PHS 22 is out of service area O or is in a power-off state. At this time, the calling side PHS20
Makes a call to the called-side PHS 22 (step 101).
(Indicated as “S101” in the figure.)), The extension reservation unit detects that the receiving side PHS 22 is out of service area O or is in a power-off state, and notifies the calling-side PHS 20 of the out-of-power-supply out-of-service notification. Perform (Step 102). At this time, the calling side PHS20
Then, it is assumed that whether or not to set an extension reservation is selected, and the caller sets an extension reservation (step 103).

Thus, the extension reservation means can be used by the extension memory 24.
Then, each data setting for extension reservation is performed (step 104). Specifically, as shown in FIG.
In the extension memory 24 for 22, extension reservation is set as extension reservation / no data 24 a, and the number of the calling side PHS 20 that has made the extension reservation is registered as number data 24 b. Then, an extension reservation setting end notification is transmitted to the transmitting side PHS 20 (step 105), and a series of extension reservation setting work is terminated (step 106).

Thereafter, when the receiving side PHS 22 moves to the area I or is powered on, the PHS private branch exchange
A position registration request is transmitted to perform position registration at 10 (step 107). When the location registration is normally completed by authentication or the like, the location registration data 24c is set in the extension memory 24 for the PHS 22 on the receiving side (step 108), and the P on the receiving side is set.
A location registration completion notification is transmitted to the HS 22 (step 109)
).

Here, the extension memory 24 for the receiving side PHS 22
The extension reservation / non-reservation data 24a is checked (step 110), and if there is no extension reservation, the process is terminated. On the other hand, if there is an extension reservation, the extension number for which the extension reservation has been set is read from the number data 24b of the extension memory 24, and
The PHS 20 ringer of that number is sounded and called (step 111). If the calling side PHS 20 does not respond to the call, the call is repeated a preset number of times.

When the calling side PHS 20 responds to this call (step 112), the extension reservation means sets the called side PHS.
The ringer of S22 is sounded and called (step 113). When the called PHS 22 responds to this call (step 114), the number data 24b and the reserved / unused data 24a of the extension reserved in the extension memory 24 of the called PHS 22 are cleared (step 115), and the calling PHS 20 is cleared. And called party PH
A call is established by connecting to S22 (step 116).

The embodiment described here is a preferred embodiment of the present invention, and the present invention is not limited to this, and it is needless to say that various modifications can be made without departing from the scope of the invention. . For example, in the present embodiment, the PHS private branch exchange 10 is used alone, but the present invention is not limited to this, and a network may be configured by connecting a plurality of PHS private branch exchanges.

For example, FIG. 4 shows a first PHS private branch exchange.
A case is shown in which a common network 31 is configured by connecting the PHS 28 and the second PHS private branch exchange 30. Each of the PHS private branch exchanges 28 and 30 includes TDSWs 32 and 34 and central control units 36 and 38.
, Storage devices 40 and 42, radio base stations 44 and 46, PHS4
8 and 50 are provided. And each PHS private branch exchange 2
The TDSWs 32 and 34 of 8 and 30 are connected by a common line 52. In this case, the PHS private branch exchanges 28 and 30 can roam within the same network 31. Further, in this network 31, each PHS private branch exchange
An extension reservation means functioning between 28 and 30 is provided. In other words, if one PHS 48 makes a call to another PHS 50 and the called PHS 50 is in a call and cannot be called by the extension reservation means, the calling PHS 48 becomes available for calling after the called PHS 50 becomes available for calling. Let them know.

The storage devices 40 and 42 are, for example, databases, and the extension memories 24 corresponding to the respective PHSs 48 and 50 as shown in FIG. 3 are set. Furthermore, each storage device 4
0 and 42 store the station number of the area where the PHS of the own station exists, while the storage device of the opposite station manages which PHS of the other station has been registered in the station as shown in FIG. Like that.

An execution procedure of the extension reservation method by the extension reservation means will be described with reference to a time chart shown in FIG.

It is assumed that the receiving side PHS 50 is located outside the service area O of the areas 54 and 56 of all the PHS private branch exchanges 28 and 30, or is in a power-off state. At this time, when the transmitting side PHS 48 makes a call to the receiving side PHS 50 (step 601),
The extension reservation means detects that the receiving-side PHS 50 is out of service area O or is in a power-off state, and the calling-side PHS 48 is detected.
Then, a notification of the power out of service area is issued to the user (step 602). At this time, it is assumed that whether or not to set an extension reservation is selected by the calling side PHS 48, and the caller sets the extension reservation (step 603).

Thus, the extension reservation means sets each data for the extension reservation in the extension memory 24 of the transmission side storage device 40 (step 604). Specifically, the callee PH
In extension memory 24 for S50, extension reserved / no data 24a
Is set, and the number of the calling side PHS 48 that has made the extension reservation is registered as the number data 24b. Then, an extension reservation setting end notification is transmitted to the transmitting side PHS 48 (step 605), and a series of extension reservation setting work is ended (step 606).

Thereafter, when the receiving side PHS 50 moves to the area I or turns on the power, the PHS private branch exchange 30
A location registration request is transmitted to perform location registration (step 607). At this time, the PHS private branch exchange 30 determines whether or not the PHS 50 belongs to its own station (step 60).
8). As a result, if it is that of the own station, the same processing as step 108 and thereafter of the processing procedure shown in FIG. 1 is performed (step 609).

On the other hand, if the PHS 50 that transmitted the location registration request belongs to another station, the central control unit 38 on the receiving side issues a request for setting the location registration data of the PHS 50 to the storage device 42, and stores it in the memory shown in FIG. Write the station number of PHS50 (step
610). When the location registration data is written to the storage device 42 on the receiving side, the storage device 42 transmits the registration completion to the central control device 38 (step 611), and is further transmitted to the central control device 36 on the transmitting side (step 612). ). Upon receiving the message, the central control unit 36 sets location registration data in the extension memory 24 corresponding to the PHS 50 of the storage device 40 (step 613). Then, the extension reservation presence / absence data 24a in the extension memory 24 is checked (step 614), and if there is no extension reservation, the processing is shifted to another (step 615).
).

If there is an extension reservation, the extension number for which the extension reservation has been set is read from the number data 24b of the extension memory 24, and the PHS 48 ringer of that number is sounded and called (step 616).

When the calling PHS 48 responds to this call (step 617), a call request to the called PHS 50 is sent from the central controller 36 via the central controller 38 (step 618), and is stored in the memory 42 on the called side. Informed (step 619). In the storage device 42, the data of the other station PHS is checked (step 620), and if there is the data of the PHS 50, it is notified to the central control device 38 (step 621).
). In response to this, the central control unit 38 sends the incoming PHS 50
Ring the ringer and call it (step 622). When the called PHS 50 responds to this call (step
623), the central controller 38 stores the extension memory of the PHS 50 on the receiving side.
24 is cleared (step 624), and the calling PHS 48 and the called PHS 50 are connected to establish a call (step 62).
Five ).

According to this embodiment, when one PHS 48 transmits to another PHS 50, the PHS 50 on the receiving side is transmitted.
Is located outside the service area of the PHS private branch exchange or is in a power-off state, and the telephone cannot be talked to, the caller PHS 48 re-registers with the PHS private branch exchange.
Is notified that the receiving-side PHS 50 is ready for a call, so that the caller can quickly make a call to the receiving-side PHS 50 to make a call.

In each of the above embodiments, the transmitting side P
The HS 20 and 48 are notified by ringing the ringer that the receiving-side PHSs 22 and 50 are ready to talk, but the present invention is not limited to this and may be notified by vibration or display.
