DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system cordless telephone device.

[0002]

2. Description of the Related Art Conventionally, this type of system cordless telephone device includes a master unit and a slave unit wirelessly connected to the master unit.
It is added to the key telephone main unit in the form of an add-on, and can be mixed with a wired general telephone.

The master unit is connected to the main unit by wire, performs data communication similar to that of the key telephone, and is installed at an appropriate place in the premises to form a wireless zone. The master unit holds the call in addition to the connection control. However, only one slave unit can hold the call with one master unit. If simultaneous calls are required in the same area, multiple master units can be connected. They are installed together as a master unit group. Therefore, when there are a plurality of areas, a plurality of parent device groups are set in each area.

A plurality of slave units are prepared according to the number of master units, and are installed in a premises in the same manner as a general extension telephone. Each of them is a low power cordless telephone, can move within a range of about 100 m in line-of-sight distance, and can be connected to an arbitrary base unit.

[0005] These slaves are managed by the location registration management function of the system cordless telephone so as to manage which master belongs to the service area. When starting use of this system cordless telephone device, it is necessary to set the location registration in the slave unit in advance, and the location registration data notified from the master unit of the master unit group to which the slave unit belongs is stored in the memory of the slave unit. It is set by storing.
At the time of transmission, access is made to the control station of the group.

On the main unit side as well, the location registration data of the child device is notified from the parent device, which is stored in a memory, and which parent device is used to call the child device at the time of incoming connection from a line or the like. It is used as data for determining whether to call.

[0007] This location registration data must be updated as needed as the slave unit moves. In this system, the master unit periodically outputs a position registration instruction request to a slave unit within its own service area. This is performed by manually outputting a position registration instruction request and receiving and updating a response signal. In any case, the data on the main device side is updated at the same time.

Further, when a large number of master units are installed in the same wireless area, when each master unit performs a location registration operation, a control channel is exclusively used for the location registration operation, and when a connection is made between outgoing / incoming calls. In order to avoid this, only one master unit in the master unit group can control the position registration operation.

As described above, even in the above-mentioned conventional system cordless telephone device, by registering and managing which parent device group a child device belongs to on both the main device side and the child device side,
Outgoing and incoming calls are possible no matter where the handset moves on the premises.

[0010]

However, in the above-mentioned conventional system cordless telephone device, the location can be registered in any parent device group when the child device moves,
There has been a problem that the call loss rate of the child device increases in a specific parent device group, and it is not possible to operate independently for each parent device group.

The present invention has been made to solve such a conventional problem, and is intended to regulate a parent device group to which each child device can be connected, thereby constructing and operating a system according to user needs. An object of the present invention is to provide an excellent system cordless telephone device.
