Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used in a personal handy phone system (PHS).
Particularly, it relates to line connection control in a local network.

[0002]

2. Description of the Related Art The public-use PHS currently under study is characterized in that it can share a cordless phone such as a home or an office with a public terminal, and has a public telephone network (PSTN).
When the terminal connected to the Public Switched Telephone Network) moves to the public space, it is connected to the public PHS network. In addition, a digital cordless phone for business use, which was developed prior to the realization of the public PHS, is being studied so that the terminal can be shared with the public PHS in the future.

FIG. 4 shows a sequence when an incoming call is made from a public PHS network to a public PHS terminal (PS). Here, "incoming call" refers to an event from when the public PHS network sends "call setup" to "call" in this sequence. Further, "authentication" means an event from the public PHS network issuing an "authentication request" to the arrival of the "authentication response" in the public PHS network in this sequence.

A base station (CS: Cell Station) that has received a call setup from the public PHS network is a public PHS terminal (PS:
Send incoming call to Personal Station). The public PHS terminal receiving the incoming call returns an incoming call response to the base station. The base station receiving the incoming call response sends the call setting to the public PHS terminal, and the public PHS terminal returns the call setting acceptance to the base station. Upon receiving the call setting acceptance from the public PHS terminal, the base station sends the call setting acceptance to the public PHS network. The public PHS network that has received the call setup acceptance sends an authentication request to the base station. The base station that has received the authentication request from the public PHS network sends the authentication request to the public PHS terminal, and the public PHS terminal returns an authentication response to the base station. The base station which receives the authentication response from the public PHS terminal sends the authentication response to the public PHS network. After the base station sends an authentication response to the public PHS network, the public PHS terminal sends a call to the base station. The base station receiving the call from the public PHS terminal sends the call to the public PHS network. After the base station sends a call to the public PHS network, the public PHS terminal sends a response to the base station. After the base station sends a response to the public PHS network, the base station sends a response confirmation to the public PHS terminal. After the base station sends a response confirmation to the public PHS terminal, the public PH
The S network sends a response confirmation to the base station and the call is started.

Regarding this sequence, the TTC
The description of the standard JT-Q931-b Appendix VI can be referred to.

In the conventional private branch exchange, by registering the terminals in the private branch in advance,
The call can be transferred to another terminal without arriving at the transfer source terminal. Similarly, such call transfer is possible between current office digital cordless phones and between office digital cordless phones and PBXs. Specifically, when an incoming call arrives, the private branch exchange responds instead of the transfer source terminal to hold the call and calls the transfer destination terminal.

However, when a public PHS terminal and a private mobile communication terminal are to be shared, authentication is required between the public PHS network and the PHS terminal, and therefore, the call is transferred by the conventional method. I can't. More specifically, when calling a private PHS terminal from the public PHS network, it is necessary to exchange an authentication code (authentication key) of the private PHS terminal between the public PHS network and the private PHS terminal. is there. However, in order to prevent misuse, the authentication code cannot be held in any place other than the public PHS network, and the private branch exchange without the authentication code cannot substitute the sequence that requires the authentication code. As a result, public PH
An incoming call from the S network to the private PHS terminal cannot be transferred to another private PHS terminal or wired terminal without arriving at the terminal.

The present invention solves such a problem, and when a public PHS terminal and a private PHS terminal are shared,
A line connection that allows an incoming call from a public PHS network to a private PHS terminal to be transferred to another local terminal before it arrives at the private PHS network without disclosing the authentication code of the private PHS terminal to the private network. An object of the present invention is to provide a control method and device.
