Abstract

PURPOSE: To transfer an incoming call to a cordless terminal in a private network to a PBX communication terminal by connecting a private PHS controller receiving private PHS terminals and public PHS network channels to a PBX provided with a transfer function and receiving communication terminals and public telephone lines. CONSTITUTION: In the case where a PS(PHS terminal) 112 moves into a private network zone, the PS 112 registers the position of the PS 112 to a database 121 via a CS (private PHS controller) 114 by using a transfer controller 120 and registers the position to a public PHS network. In the case of automatic transfer registration, in succession to the position registration, a device 120 obtains a number corresponding to the PS from a database 122 and registers an incoming call to be transferred to a PHS controller 103. In the case of the manual transfer registration mode, the PS 112 updates the position registration based on a transfer registration operation by the user by using the device 120 via the CS 114 to obtain a transfer source number and registers an incoming call addressed to the number to be transferred to the controller 103.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS mobile terminal (hereinafter PS) that realizes a service of a simplified mobile phone system (hereinafter PHS) that can access a public PHS network.
When the subscriber is registered in the S network and can make and receive calls in the private network, the terminal mobility between the public PHS network and the private network, and the personal mobility of the cordless terminal owner in the private network. The present invention relates to a control method of a local area network that enables

[0002]

2. Description of the Related Art Communication in a conventional private network is performed by a communication terminal connected to a main device (hereinafter, PBX) of the private network. This communication terminal is connected to not only a wired terminal but also a cordless terminal (including PS). Within the campus network,
Communication between wired terminals and cordless terminals, between wired terminals, or between cordless terminals is possible with an extension number. However, when a PS that is registered in the public PHS network moves from the local network to the public PHS area, When receiving an incoming call to the PS, the extension number given to the PS or communication terminal, or the private network number (hereinafter, CPN) which is a personal number given to the individual
Cannot be used, the public PHS number (hereinafter PSN) must be used.

Further, in the private network, a subscriber who receives a dial-in receiving service from the public network by the dial-in number (hereinafter referred to as DIN) assigned to the PBX is PS.
If you carry the phone with you and move to the public PHS area, you cannot receive the incoming call by the DIN unless you register for transfer to the public network.

Further, when the PS located in the public PHS area returns to the local network, it cannot receive an incoming call by DIN from the public network. Further, in the private network, when the PS owner moves to a communication terminal accommodated in the PBX, the communication terminal cannot receive an incoming call by PSN from the public PHS network.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is that a PS that realizes a PHS service that can access a public PHS network is already registered and registered in the public PHS network, and is capable of making and receiving calls in the private network as well. In this case, not only the incoming call to PS of the private network by PSN is transferred to the communication terminal accommodated in the PBX, but also the incoming call by the DIN assigned to the PBX in the private network or the incoming by CPN from the terminal of the private network. Also, it is to enable transfer to the PS.

[0006] As a result, when a PS registered for subscription to the public PHS network moves from the local network to the public PHS area, the PSN must be used for the incoming call to the PS, and the public network according to the DIN. A subscriber who receives the dial-in incoming call service from
If you move to the area, you will not be able to receive incoming calls using the DIN unless you register for transfer to the public network.
When the PS located in the public PHS area returns to the private network, it cannot receive an incoming call by DIN from the public PHS network.
When moving to a communication terminal accommodated in BX, public PHS
It is to realize the private network communication which solves the problem that the communication terminal cannot receive the incoming call from the network to the PS of the private network.

[0007]

A PBX having a transfer function for accommodating a communication terminal and a public telephone line in a private network,
Premises PH that accommodates premises PHS terminals and public PHS network lines
By connecting the S control device, the PS can be accommodated without renewal or modification of the PBX, and the PS by extension number or DIN
The main feature is that the incoming call to the PBX and the transfer of the incoming call by the PSN to the PBX are possible.

[0008] The function of the on-site PHS controller is P
A means for transferring an incoming call to a number designated to the BX to the local PHS controller, a means for receiving the call transferred from the PBX to the local PS, and a PSN from the public PHS network to the local network. Means for transferring an incoming call to the communication terminal specified by the PBX, and means for transferring an incoming call to the PS from the PBX to the public network when the PS is in the public PHS network.

The difference from the prior art is that the P
The PS can be connected to the public PHS network and the PBX by connecting the control device to the PBX without renewing or modifying the BX, and an incoming call from the public PHS network to the PS of the private network can be transmitted to the PBX. In that it can be transferred to a communication terminal accommodated in the PBX, that transfer registration to the PS for the PBX can be easily performed, and that a transfer call from the PBX to the PS can be transferred to the public network when the PS is in the public PHS network. is there.

It is transferred to the local PHS control device 103 via the signal path 106 by the X 102 and notifies the wired terminal 111 of the incoming transfer call. Further, the transfer controller 120 uses the database 122 to connect the PPN by the CPN of the wired terminal 111.
The PSN of S113 is obtained, the position information of the PS113 is obtained from the position registration database 121, and the P is transmitted via the CS114.
The call is made to S113 (FIG. 5A).

When a CPN-originated call from another PS 113 located in the local network area to the PS 112 is obtained by the transfer control device 120 from the database 121 of the location information of the PS 112, and if the PS is within the local area network, the CS 114 is used. The PS 112 receives an incoming call via. If the power of the PS 112 is cut off, or if it is outside the network area of the premises,
If there is a number corresponding to S112, it is transferred to the PBX 102 (FIG. 5B).

(5) Incoming call from public network: public network 100
When there is an incoming call from the PBX 102 via the public line 104 to the DIN corresponding to the PS 112 existing in the local network, the PBX 102 sends the local PH via the signal path 106.

[0027]

As described above, according to the present invention, the PHS portable terminals that can be shared between the public PHS network and the local network move to each other between the public PHS network and the local network. At this time, in order to communicate with the PS from another terminal of the public network, an incoming call by PSN to the PS of the private network is not only transferred to the communication terminal accommodated in the PBX but also given to the PBX of the private network. In order to enable incoming calls using the dial-in number and to communicate with the PS from other terminals on the local network, the P
By enabling the transfer to the S, it is possible to improve the convenience of the local network user. Further, it becomes possible to accommodate the PHS mobile terminal in the local network without renewing or modifying the PBX to realize the above function.
