The present invention relates to a separate wireless subscriber network (WLL), and in particular, selects one of several stations connected in a separate wireless subscriber network and applies a ring to the selected station to select a station that is suitable for selecting an extension. It relates to the extension selection method of own network.

In general, a wireless subscriber network (WLL) system using a code division multiple access (CDMA) wireless access standard is provided by a narrowband-CDMA (N-CDMA) system and a wideband-CDMA (W-CDMA) system. Compared to the N-CDMA scheme, the W-CDMA scheme has a difference in frequency bandwidth, voice band data rate, and ISDN BRI (2B + D) service.

In addition, the wireless subscriber network system is a system that replaces a predetermined interval between each subscriber's home and the public line exchange by wireless instead of wires in the existing Public Switching Telephone Network (PSTN) system. A mobile terminal (MT) that receives a user's signal from a telephone (TE) in a home and transmits it to a base station, and a wireless base station that is in charge of connecting and disconnecting a bearer wirelessly with the subscriber wireless access device A base station (BS), a wireless base station controller (BSC) which performs a function of connecting a call link between the switch and the wireless base station (BS), and establishes a link of a call with an existing public line switching network (PSTN) It consists of a mobile subscriber line network switch (MSC).

Therefore, the wireless subscriber network can easily install the telephone network than the existing wired network system, the cost of facility expansion is low, and the flexibility of the network design according to the increase of subscribers has the advantage.

In addition, unlike conventional narrowband CDMA networks, W-CDMA wireless subscriber systems enable the implementation of integrated services digital network (ISDN) services and packet networks as well as call, fax and data transmission. .

As shown therein, an eleventh step ST31 for determining whether a ring generation command and a caller's telephone number have been received from the base station; Receiving a ring generation command and a calling party number, determining whether a calling party number has been received from the base station, and determining whether there is a telephone number corresponding to the telephone number entered in each extension number. Steps ST32 and ST33; If there is a matching telephone number, a thirteenth step ST34 of transmitting a ring signal only to the extension of the matching telephone number is performed.

The method for selecting an extension of the detachable wireless subscriber network may include determining whether the corresponding station is off-hook within a predetermined time after performing the thirteenth step (ST35); If the extension does not off-hook within the predetermined time period, or if the calling party telephone number is not received from the base station, or if the received calling telephone number does not exist with a telephone number that matches the telephone number entered in each extension number, And transmitting the ring signal (ST36).

In the thirteenth step ST34, the relay of the remaining extension is opened except for the relay of the extension to which the received caller's telephone number is input, and the ring signal is transmitted only to the extension of the corresponding telephone number.

An apparatus for selecting an extension of a split type wireless subscriber network and a method of the method according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the present invention is to select one of a number of extensions that are connected by using a caller's telephone number in a separate wireless subscriber network.

Thus, as shown in FIG. 3, by configuring the relay unit 20 in each station to selectively connect each station, a ring signal is selectively supplied to each station.

Therefore, enter the telephone number that you want the ring to ring at each station, and when the ring origination command and the calling party number are received from the base station, if the caller's phone number that is received is entered as the telephone number you want the ring to ring at, Only the station will ring.

The operation of the present invention will be described in more detail with reference to FIGS. 4 and 5 as follows.

First, in order to input a specific phone number to a specific extension so that a call from a specific phone rings only on a specific extension, do the following:

That is, as shown in FIG. 4, a specific code for inputting a telephone number is input, and an extension number for inputting a telephone number is input. And by inputting a phone number to ring the phone ring to the extension, and enters the end code that completes the phone number input to the extension.

When the call is received from the outside, the operation of the wireless subscriber network terminal (WLL) is as shown in FIG.

Thus, after receiving the ring command from the base station, it is determined whether the caller's telephone number has been received from the base station.

If the caller's telephone number is not received from the base station, a ring signal is sent to all stations so that the ring rings at all stations.

When receiving a caller's telephone number from the base station, it is determined whether the telephone number received at each extension is registered in order to ring the telephone at a specific extension.

If the telephone number received in each station is not registered, a ring signal is sent to all stations so that all stations ring.

If the telephone number received at each station is registered, the relay of the corresponding station is connected and the other relays are disconnected by controlling by the CPU 14 using a relay control line. Therefore, the stations other than the corresponding extension are disconnected, and the lines of the terminal and the telephone are disconnected, and the CPU 14 supplies the ring signal only to the extension to which the received telephone number is registered. Then, only the phones connected to the corresponding station receiving the ring signal will ring.

Then, it is determined whether the extension supplying the ring signal receives the call within a predetermined time.

If the call is not answered within a certain time, all stations send ring signals to ring all stations. This allows you to receive calls from any telephone connected to your extension.

If the call is received within a certain time, only the extension can talk to the caller.

As described above, the present invention selects an extension by applying a ring to a selected extension by selecting one of several extensions connected by using a calling party telephone number in a separate wireless subscriber network.

Although the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Accordingly, the above description does not limit the scope of the invention as defined by the limitations of the following claims.

As described above, the extension selection method of the detachable wireless subscriber network according to the present invention applies a ring to a selected extension by selecting one of several extensions connected by using a caller ID in the detachable wireless subscriber network. By doing so, the extension can be selected.

In addition, the present invention is to ring only to a specific extension for a specific telephone number, if a number of telephones connected to the wireless subscriber network terminal is installed in a number of rooms, only the call to the person using the room is the extension of the By ringing the phone only, it is possible to eliminate the inconvenience that other users receive the call to switch, and also has the effect of protecting the privacy of the person using the phone.
