Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to, for example, a PHS (Personal Handyphone S) for public use.
and a plurality of types of mobile communication networks such as a private mobile communication network that provides services to a limited number of users in business offices and office buildings such as a private PHS. The present invention relates to a mobile communication system provided, and more particularly, to a mobile communication system that efficiently processes, for example, a call request from a mobile terminal existing in a public wireless service area to a mobile terminal existing in a private wireless service area.

[0002]

2. Description of the Related Art Conventional mobile communication systems include automobiles and automobiles.
A public mobile communication network, such as a mobile phone system or a public PHS, that provides services to general subscribers;
Like the HS, there is a private mobile communication network that provides services to a limited number of users in an office or an office building.

[0003] In a public mobile communication network, a plurality of base stations are connected to a public communication network via a subscriber line, and mobile terminals existing in a wireless service area formed by these base stations are connected to the public via the base station. It enables communication by connecting to a communication network. The mobile terminal performs location registration with the public communication network in advance, and is connected to the public communication network by making and receiving calls based on a numbering plan determined by the public communication network.

On the other hand, the private mobile communication network connects a control device such as a private branch exchange or a concentrator installed in a business office or an office building to a public communication network via a group of subscriber lines, and connects the control device to the control device. A plurality of base stations are connected via a private communication line. Then, by connecting the mobile terminal to the control device via these base stations and further connecting to the public communication network via the control device, extension communication between a plurality of mobile terminals and the mobile terminal and the public communication network can be performed. External line communication with the external device. The mobile terminal used here is
The location is registered in the control device in advance, and the device is connected to a public communication network by calling and receiving based on a numbering plan determined by the control device.

Conventionally, when a mobile terminal existing in a public wireless service area sends a call request to a mobile terminal existing in a private wireless service area, all of the requests are sent between the public communication network and the control device of the private mobile communication network. It is processed via the connecting subscriber line group. That is, as shown in FIG. 14, a transmission request from the mobile communication terminal 4 existing in the wireless service area formed by the public base station 2 to the mobile communication terminal 4 existing in the wireless service area formed by the local base station 3 is Are all transferred from the public communication network 1 to the mobile communication control device 10 via the subscriber line group 5. Therefore, there is a problem that the line facility cost and the communication cost are increased more than expected depending on the use situation.

[0006] In recent years, most mobile terminals are used as public mobile terminals in public wireless service areas, while most of them are used as local mobile terminals in private wireless service areas. The number is usually different between a case where the mobile terminal is used as a public mobile terminal and a case where it is used as a private mobile terminal. For this reason, the user of the mobile terminal existing in the public wireless service area,
There was a problem that the user had to force the dial operation in consideration of the location of the other party.

[0007]

As described above, in the conventional mobile communication system, all outgoing requests from a mobile terminal located in the public wireless service area to a local mobile terminal located in the private wireless service area are sent. Since the processing is performed via a group of subscriber lines connecting the public communication network and the control device of the private mobile communication network, there has been a problem in that line facility costs and communication costs are increased. In addition, users of mobile terminals within the public wireless service area
There was a problem that the user had to force the dial operation in consideration of the location of the other party.

The present invention has been made in view of such circumstances, and efficiently processes a transmission request from a mobile terminal located in a public wireless service area to a local mobile terminal located in a local wireless service area. An object is to provide a mobile communication system.

[0009]

According to the present invention, in order to achieve the above-mentioned object, for example, a radio antenna device accommodating a public base station forming a public radio service area is accommodated in a control device of a private mobile communication network. However, when the destination of the transmission request transmitted through the wireless antenna device is a mobile terminal whose location is registered in the private mobile communication network, that is, a mobile terminal existing in the private wireless service area. Sometimes, incoming call processing for the mobile terminal is performed.

That is, according to the present invention, a call request from a mobile terminal located in a public wireless service area to a mobile terminal located in a private wireless service area is provided.
Since the processing can be performed without passing through the group of subscriber lines connecting the public communication network and the control device of the private mobile communication network, it is possible to greatly reduce the line facility cost and the communication cost. In addition, since the mobile terminal existing in the private wireless service area can be terminated by the subscriber number for the public mobile terminal, the location of the destination is considered for the user of the mobile terminal existing in the public wireless service area. No need to force dial operation.

Further, according to the present invention, the control device notifies the radio antenna device of the terminal identification information of the mobile terminal registered in the private mobile communication network, and the radio antenna device transmits the terminal identification information from the public base station. It is determined whether or not the terminal identification information of the destination of the transmitted transmission request is a mobile terminal whose location is registered in the private mobile communication network.

That is, in the present invention, when it is determined that the mobile terminal is not a mobile terminal whose location is registered in the private mobile communication network, for example, a disconnection process for the mobile terminal of the transmission source can be executed on the wireless antenna device side. Therefore, the processing load on the control device can be reduced.

[0013] It is preferable that the control device accommodates a plurality of wireless antenna devices having different reception radio waves. As a result, the service type can be provided to an unspecified number of users because the type of the mobile terminal registered in the mobile communication network is not specified.
