DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a PHS (Personal Handy).
phone System). In particular, the present invention relates to a technology shared by a public PHS terminal and a private mobile communication wireless terminal. More specifically, the present invention relates to a line connection control between a private mobile communication radio terminal and a public PHS network via a private base station.

[0002]

2. Description of the Related Art Currently, public PHSs are considered as cordless phones for homes or offices and public PHSs.
One of the features is that the terminal can be shared. That is, when a mobile phone terminal connected to a general telephone network via a base unit installed in a home or an office moves to a public space, a public PHS is transmitted via a base station installed in the public space. It is connected to the network. Such a mobile phone terminal is hereinafter referred to as “PS (Personal S)
tation) ".

FIG. 8 shows an incoming sequence from a public PHS network to a public PS. This sequence is based on the TC Standard JT
-Q931-b as shown in Appendix VI. Here, the term “incoming call” refers to an event from when the public PHS network transmits “call setup” to when the call reaches “call”. “Authentication” means that the public PHS network sends an “authentication request”
It means an event until an authentication response arrives at the HS network.
The incoming call is performed as follows. (1) The public PHS network requests call setup from a base station (CS: Cell Station), and the base station sends an incoming call to a public PS. (2) The public PS receiving the call returns a call response to the base station. (3) The base station sends a call setup to the public PS. (4) The public PS that has received the call setting returns a call setting reception to the base station, and the base station sends the call setting reception to the public PHS network. (5) The public PHS network sends an authentication request to the base station, and the base station sends an authentication request to the public PS. (6) Upon receiving the authentication request, the public PS returns an authentication response to the base station, and the base station sends the authentication response to the public PHS network. (7) After the base station sends an authentication response to the public PHS network, the public PS sends a call to the base station, and the base station sends a call to the public PHS network. (8) After the base station sends a call to the public PHS network, the public PS sends a response to the base station, and the base station sends a response to the public PHS network.
Send a response to the network. (9) After transmitting a response to the public PHS network, the base station transmits a response confirmation to the public PS. (10) After the base station sends a response confirmation to the public PS, the public PHS network sends a response confirmation to the base station. (11) A call is started.

In addition, digital cordless phones for business establishments, which were developed prior to the realization of the public PHS, are being studied in the future so that the terminals can be shared with the public PHS.

[0005]

The conventional digital cordless telephone for business use is used in combination with a private branch exchange, and can be operated in a self-owned mode from a general public network or a wired terminal in the premises through a base station installed in the premises. With this wireless interface, an incoming call can be made to a private mobile communication wireless terminal (hereinafter referred to as a private PS). Further, by registering another terminal in the premises in advance, it is possible to transfer an incoming call to the premises PS to another terminal without arriving at the PS.

However, when the public PS and the private PS are shared, the operation mode becomes a problem. That is, when the public PHS network issues a call to the private PS, it is necessary to exchange an authentication code (authentication key) for the private PS with the network. Therefore, the premises base station accesses the PS through the wireless interface in the public mode. At this time, if the PS is waiting in the private mode, the incoming call fails because the mode is different. Also, when the mobile station is waiting in the public mode, the incoming call from the public PHS network can be received, but the incoming call of the extension fails because the mode is different.

[0007] In addition, since an incoming call from the public PHS network is performed in the public mode, the terminal must be authenticated. Therefore, it is impossible to transfer an incoming call from the public PHS network to the private PS to another terminal, for example, a wired terminal.

An object of the present invention is to solve such a problem and to provide a line connection control method and apparatus system which can effectively use a public PS and a private PS by sharing them.

[0009]

A first aspect of the present invention is a line connection control method, which is connected to a public network via a private line connection means in a limited space and is directly connected to a public space. In a line connection control method for controlling a line connection to a mobile telephone terminal connected to a public network, a public authentication code to be transmitted to the public network for the mobile telephone terminal to be directly connected to the public network is connected to a private line connection. Means, and when a call is received from the public network to the mobile phone terminal, the private line connection means performs authentication between the public network and the terminal whether or not the terminal is registered with the public network. And

[0010] When a call is received from a public network to a mobile phone terminal,
The connection between the private line connection means and the mobile phone terminal can be made in a private mode.

When the transfer destination from the mobile phone terminal is registered in the private line connection means in advance, it is preferable to transfer an incoming call from the public network to the mobile phone terminal to another terminal.

A second aspect of the present invention is an apparatus used as a private line connection means in the above-described method, wherein a portable telephone terminal in a limited space and another telephone terminal via a public network or a private branch exchange are connected. In a line connection control device for controlling connection, a storage means for storing information for connecting a mobile phone terminal including a public authentication code to a public network, and a mobile phone for receiving a call from the public network to the mobile phone terminal The information on the terminal is searched by the storage means, and if the information on the mobile phone terminal is registered, the terminal is registered on the public network with the public network in place of the mobile phone terminal. Control means for performing authentication as to whether or not there is a communication device.

The storage means includes means for storing a transfer destination when a call is received by the mobile phone terminal, and the control means includes means for transferring an incoming call to the mobile phone terminal from the public network to another terminal. Good.

[0014]

When the PS for public use and the PS for private use are shared, the public authentication code of the terminal is registered in the private line connection means, and the private line connection means substitutes an incoming call from the public PHS network to the terminal. To respond. As a result, it is possible to receive a call to the premises PS in the private mode. It is also possible to transfer the call to another private PS or a wired terminal without receiving the call to the terminal.
