[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-zone cordless system which enables the operation of a cordless terminal which can be moved arbitrarily in a premises. And a method for notifying the originating subscriber of the location information.

[0002]

2. Description of the Related Art In recent years, with the progress of telephone exchange technology, cordless telephone terminals that enable wireless communication between terminals have become widespread.

[0003] In addition, demand for cordless telephone terminals is increasing as telephones installed in buildings of companies and the like. Here, a cordless telephone terminal that is widely used in ordinary households has a single base unit connected to a telephone line cable. Then, a plurality of cordless telephone terminals (slave units) capable of wirelessly transmitting and receiving with the master unit are provided. In this case, the base unit can communicate only with a specific cordless telephone terminal, and further defines a communicable range. For this reason,
Cordless telephone terminals outside the range will not be able to talk. When this cordless terminal is installed in a building of a company or the like, particularly when the premises covers a plurality of floors of a building, it is impossible to manage the cordless terminals in various parts of the premises with a single master unit. Therefore, there is known a multi-zone cordless system in which a campus is divided into a plurality of areas and a master unit is installed for each area. In this system, the base unit manages communication only for cordless telephone terminals in the area where the base unit is installed.

[0004] An arbitrary master unit grasps a cordless telephone terminal located in its own area by receiving a weak radio wave from a cordless telephone terminal located in its own area.

Further, the base unit transmits a weak radio wave within its own area, receives a response signal of this radio wave, and recognizes the cordless telephone terminal of the response source from the response signal, so that the base unit within its own area is transmitted. You know the cordless phone terminal located in.

[0006] Further, the base unit transmits the incoming call number of the cordless telephone terminal located in its own area (or terminal identification information for specifying each cordless telephone terminal) to the private branch exchange. The private branch exchange is provided with a table for storing the area number where each cordless telephone terminal is located, together with the called number (or specific identification information) of each cordless telephone terminal. When there is a call request to an arbitrary cordless telephone terminal, the table is referred to based on the called number (or specific identification information) of the call destination cordless telephone terminal, and the call destination cordless telephone terminal is located. Detect area. Then, the call destination is notified to the call destination cordless telephone terminal via the base unit installed in the area.

[0007] When any cordless telephone terminal moves out of its own area, each master unit notifies the private branch exchange of the fact. On the other hand, when a new cordless telephone terminal moves into the own area, the same is notified to the private branch exchange. Thus, the private branch exchange can receive the notification from each parent device, update the table, and recognize the position of each cordless telephone terminal in real time.

[0008]

By the way, when a call request is made to a telephone terminal when the telephone is busy, if the telephone terminal of the call destination is a desk-top telephone terminal, the calling subscriber becomes the call destination subscriber. Although the location of the subscriber can be recognized, when the called telephone terminal is a cordless telephone terminal, the calling subscriber cannot grasp the position of the calling subscriber. For this reason, in an emergency, there is a possibility that information transmission will be delayed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to increase the speed of information transmission by notifying a calling subscriber of the position of a busy cordless telephone. And

In the present invention, a private branch exchange 3 that enables a plurality of cordless terminals 1 to operate through the relay unit 2 includes an area information registration table 4, a state management table 5, a circuit switching processing unit 6, and a control unit 7. .

The area information registration table 4 is a table for registering character information indicating the name of each area together with an area identifier for specifying each area. The state management table 5 registers an area identifier where each cordless terminal 1 is located and a call state of the cordless terminal 1. For example, an area identifier and call state information are registered for each incoming number of each cordless terminal 1. The call state information may be, for example, a flag bit consisting of “1” indicating busy and “0” indicating a talkable state.

[0013] The circuit switching processing means 6 includes the cordless terminal 1.
The transmission / reception is performed via the relay unit 2 and a call line is set up between the terminal and the cordless terminal 1. The control means 7 controls each of the above sections.

[0014]

According to the present invention, in the private branch exchange 3, when the control means 7 recognizes a call request to an arbitrary cordless terminal 1, the control means 7 accesses the state management table 5 and the call destination cordless terminal 1 It is determined whether the telephone is busy or in a callable state.

Here, when a call is possible, the circuit switching processing unit 6 refers to the area where the call destination cordless terminal 1 is located from the state management table 1 and switches the relay unit 2 in this area. A call line is set between the calling subscriber and the called cordless terminal 1 via the telephone.

On the other hand, when the call destination cordless terminal 1 is busy, the control means 7 reads out the area identifier where the call destination cordless terminal 1 is located from the state management table 5, and switches this area identifier to the circuit switching. Notify processing means 6.

The circuit switching processing means 6 accesses the area information registration table 4 based on the area identifier and reads out character information indicating the name of the area. Further, the circuit switching processing means 6 transmits a signal indicating that the called cordless terminal 1 is busy to the calling subscriber, and notifies the calling subscriber of the position of the called cordless terminal 1 based on the character information. I do. This allows the calling subscriber to
The location of the called party can be recognized, and in an emergency, the location can be reached and the called party can be accessed directly.

The character information may be audio information indicating an individual area name. In this case, the circuit switching processing means 6 transmits the voice information to the calling subscriber together with a signal indicating busy. According to this, the calling subscriber can recognize the position of the calling subscriber by voice.

Further, the character information may be character information representing an individual area name. In this case, a display function for displaying arbitrary information on the screen is added to the calling telephone terminal. The circuit switching processing means 6 transmits the character information to the calling subscriber together with a signal indicating busy. According to this, the calling subscriber can recognize the position of the calling subscriber from the character information displayed on the screen.

The calling subscriber may arbitrarily select whether or not to notify the location. That is, after transmitting the busy signal to the calling terminal, the circuit switching processing unit 6 monitors the dial signal transmitted from the calling terminal. Character information is transmitted to the calling subscriber only when a specific dial signal is received from the calling subscriber.
