BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a method for expanding a service providing range in a wireless communication system, and by connecting a plurality of existing service providing apparatuses without increasing the size of the service providing apparatus. It is intended to expand the scope of service provision.

[0002]

2. Description of the Related Art Generally, in a wireless communication system having a plurality of wireless base stations, position information of moving wireless terminals is held and managed. For this reason, in the conventional service providing apparatus having no interconnection function, in order to expand the service providing range, the service providing apparatus must be upsized and the wireless base station in a remote place can be directly accommodated by some method.

There is also a method of expanding the service providing range by installing a plurality of service providing apparatuses, but the service providing apparatus retains and manages only subscriber information and location information of only terminals accommodated in its own service providing apparatus. Therefore, the call can be made only between the terminals accommodated in the respective service providing devices, and the communication with the terminals accommodated in the other service providing devices is a call through the public network. When calling through a public network, the numbering plans in the same wireless communication system installed by the same user in a plurality of places are not unified, and the terminal accommodated in a certain service providing device is different from that of another service providing device. There was a problem that it could not be used in the service area.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and to increase the size of an existing service providing device when a wireless communication system expands the service providing range. In addition, by interconnecting existing service providing devices without accommodating a wireless base station remotely, it is possible to expand the service providing range.

[0005]

A feature of the present invention for achieving the above object is to provide a service providing apparatus which is connected to a wireless terminal for communicating via a wireless base station and is connected to a switching network. The service providing device has an interconnection device, and a plurality of service providing devices are connected via the interconnection device without passing through the switching network.

[0006] In a service providing apparatus having no interconnection function, mutual communication cannot be performed, or even if it is possible, the connection is made via the public network, so that the number of dials for making the connection increases or the same network service is provided. The problem that cannot be received occurs.

According to the present invention, an interconnection device for connecting a control signal and a communication channel is added to a service providing device having no interconnection function, and control signals are mutually transmitted and received, whereby all connected devices are connected. The service providing device
In addition to being able to operate with one subscriber database, there is a communication channel that directly connects between service providing devices, so that communication is connected without going through the public network.

As a result, the same network service can be received even in a wireless communication system in which a plurality of service providing devices are installed, and the system can be operated according to the same numbering plan.
