Abstract

PROBLEM TO BE SOLVED: To allow the system to provide an incoming call made by a public number to a PHS terminal equipment through a PBX of a company or a master set automatically so long as the PHS terminal equipment is resident in a service area of the PBX or the master set of the user's master set even when the PHS terminal equipment is resident in an area where no public radio wave reaches. SOLUTION: When a PHS terminal equipment 6c makes a call to a destination PHS terminal equipment 6a being a PHS terminal equipment 050-AAA- BBBB, the PHS terminal equipment 6c is connected to a mobile telephone exchange station 10 of a PHS network 1 from a radio base station 4. The PHS network 1 informs an incoming call to the PHS terminal equipment 050- AAA-BBBB to the PBX 2 whose PBX number is 12345678 based on (PBX number 12345678 and ID number 050-AAA-BBBB of the PHS terminal equipment 6a) informed from the PBX 2. The PBX 2 makes a call to an extension number AAA (PHS terminal equipment 050-AAA-BBBB) based on a conversion table 11 via a radio base station 5 for an enterprise use to transfer the call automatically to the PBX2 of the company so as to realize a speech.

2. Description of the Related Art FIG. 3 is a system block diagram for explaining an outline of a call by a PHS terminal. In the figure, PH
The S network 1 includes a local station 8, an area station 9, a mobile telephone exchange station 10,
The wireless base station 4 and the like are included. That is, ISD
The wireless base station 4 is provided in N (total service digital network). The wireless base station 4 is provided for each of a plurality of zones in the service area and wirelessly communicates with the PHS terminal 6. For example, when calling the other party's PHS terminal 6 from the ordinary telephone 7, the other party's telephone number is dialed. The PHS network 1 is a general telephone 7 → a local station 8
→ Toll 8 → Connect to mobile telephone exchange 10 in charge.
The mobile telephone exchange station 10 inquires of the database managing the location of the PHS terminal 6 about the service area in which the PHS terminal 6 is located, and connects to the mobile telephone exchange station 10 in charge of this service area. The mobile telephone switching center 10 calls the PHS terminals 6 all at once through all the radio base stations 4 in the service area. Since the PHS terminal 6 communicates with the wireless base station 4 in the zone in charge by using the vacant frequency, the calling side can talk with the PHS terminal 6 of the other party.

FIG. 4 is a system block diagram for explaining an outline of another call made by the PHS terminal. The other side is the same as FIG. 3 except that the calling side is replaced by the PHS terminal 6 from the ordinary telephone 7. Even in this case, the destination telephone number is dialed. In the PHS network 1, the radio base station 4 connects to the mobile telephone exchange station 10 in charge, and the mobile telephone exchange station 10 has a database that manages the location of the PHS terminal 6 and provides a service indicating the location of the PHS terminal 6. Inquires about the area and connects to the mobile telephone exchange 10 in the service area in charge. The mobile telephone switching center 10 calls the PHS terminals 6 all at once through all the radio base stations 4 in the service area in charge. The PHS terminal 6 communicates with the radio base station 4 in the zone in which the PHS terminal 6 responds, using the vacant frequency.
As described above, even in the PHS, it is possible to perform both outgoing and incoming calls as in the existing telephone system.

By the way, the PHS has two modes, a public mode and a self-employed mode, and the PHS terminal 6 can select these two modes. In the public mode, the wireless base station 4 installed by the communication carrier and the PHS terminal 6 make a wireless call. On the other hand, in the self-employed mode, the PBX of the company installed by the user or the base unit of the home and the PHS terminal 6 communicate wirelessly. The PBX of these companies and the parent device at home make a call using a general line.

[0005]

However, in such a conventional PHS communication network, the distance over which the wireless base station 4 and the PHS terminal 6 can communicate with each other is several hundred meters. Station 4 is typically installed outdoors. For this reason, it is difficult for radio waves to reach indoors, and it may be impossible to make a call depending on the area. In addition, since radio waves cannot enter from the outside in a closed space such as inside a certain facility, the PHS terminal 6 cannot make a call. Since such a wireless base station 4 is installed by a communication carrier, the user of the PHS terminal 6 cannot make a call in an area or facility where the wireless base station 4 is not present.
That is, in PHS, when the PHS terminal 6 is used at work or home, when the incoming mode is used only at work or home,
Alternatively, if the PHS terminal 6 is located in an area where public radio waves cannot reach, even if a call is made using a public number, the other party's P
There is a problem that the HS terminal 6 does not receive a call.

Moreover, even in the PHS self-employed mode,
You can make a call in the same way as in public mode,
Since there is no function for managing the position of the PHS terminal 6 for incoming calls,
It is unknown whether the PHS terminal 6 exists in the area.
Also, since the incoming call is made to the PBX on the general line or the telephone number corresponding to the master unit, the PHS terminal 6 is set to P
The only way to confirm was to try calling regardless of whether it was in the service area of the BX or the base unit.

The present invention has been made in view of the above points, and even if the PHS terminal 6 is in an area where public radio waves do not reach, as long as it is within the service area of the PBX of the company or the parent device at home. It is to provide a PHS automatic transfer method in which an incoming call is automatically given through a PBX or a base unit even if a public number is used.

[0008]

[Means for Solving the Problems] When a PBX of a company recognizes a specific PHS terminal that has entered the service area as an extension via a wireless telephone station for business establishments, the PBX corresponds to the terminal number and extension of the PHS terminal. The ID number and PBX number of the PHS terminal are notified to the PHS network of the carrier of the ISDN network based on the conversion table. On the PHS network side, when there is a call to the PHS terminal with this ID number, the PBX side is notified of the incoming call. Based on the conversion table, the PBX calls the PHS terminal corresponding to this ID number via the wireless telephone station for business and starts a call. In this case, PH
It is necessary for the S terminal to select the self-employed mode.

Similarly, when the parent device at home recognizes the PHS terminal as a child device, the ID number of the PHS terminal and the telephone number of the parent device are calculated based on the conversion table that associates the terminal number of the PHS terminal with the extension number. PHS of telecommunications carrier of ISDN network
Notify the web. On the PHS network side, the PHS of this ID number
When there is a call to the terminal, the call is notified to the base unit. The parent device is the P corresponding to this ID number based on the conversion table.
Call the HS terminal and start a call. In this case, PH
It is necessary for the S terminal to select the self-employed mode.

That is, when the PHS terminal is recognized as an extension or a slave unit, an ID in which the public number of the PHS terminal is attached to the PHS network according to the data in the conversion table.
When the PHS network receives a call to the PHS terminal, the PHS network notifies the PBX and the master unit of the notification of an incoming call based on the ID number of the PHS terminal.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The PHS automatic transfer system according to the present invention comprises a conversion table 11 for associating the terminal number of the PHS terminal 6 and the extension number with the PBX 2 of a company which can handle the PHS terminal 6 as an extension terminal. When the PBX 2 recognizes that a specific PHS terminal 6a has entered the service area 12, the PBX 2 sets the ID number and PBX number that can confirm the PHS terminal 6a based on the conversion table 11 to P
The HS network 1 is notified, the PHS network 1 notifies the PBX 2 of an incoming call to the PHS terminal 6a based on the notification of the ID number, and the PBX 2 that has received the incoming call notification notifies the PHS terminal 6a of the PHS terminal 6a based on the conversion table. The PHS terminal 6 can be called by calling wirelessly via the radio base station 5 for the business office of the PBX 2.
