Description

[Detailed description of the invention] (Industrial application field) The present invention relates to cordless telephone systems, and more particularly to cordless telephone systems.

It relates to mobile objects (mobile terminals) that apply the location registration function in cordless telephone systems.

(Conventional technology) Generally, for portable cordless telephone systems.

Equipped with a mobile device location registration function.

The location registration function of a mobile terminal in a portable cordless telephone system does not have a one-to-one correspondence between a mobile terminal and a zone, or between a mobile terminal and a wireless line. It is a functional function. On the premise that this location registration function is provided, the portable cordless telephone system can perform call processing similar to that of a general exchange accommodating fixed subscribers.

On the other hand, if an electrical system is used to display destinations for employees within a business office, a dedicated device for displaying nine destinations will be constructed independently, or a destination display system will be installed on the private branch exchange as a service accompanying the private branch exchange. It is common to incorporate

(Problem to be solved by the invention) However, this location registration function affects the overall system configuration, such as switching equipment, mobile terminals, and the signaling system between these two devices. There is a problem in that it is a factor in increasing costs compared to a general telephone system that accommodates devices.

Accordingly, two objects of the present invention are to provide a cordless telephone system capable of displaying a destination using a location registration function, thereby reducing costs.

(Means for Solving the Problems) According to the present invention, there is provided a plurality of wireless terminal devices and a connecting device connected to the wireless terminal devices by a wireless line and connected to a telephone subscriber line.

In a cordless telephone system, the connecting device includes a location information registration means for registering location information of the wireless terminal device, an extraction means for extracting location information registered in the location information registration means, and location information from the extraction means. A cordless telephone system is obtained, characterized in that it has a display means for displaying.

(Example) The present invention will be explained below with reference to Examples.

The cordless telephone system consists of subscriber circuits LCI to LC6.
, communication path section (switch section) SW, communication path control circuit SWC
, a main control unit CC, a location registration information transfer circuit LIS, and wireless connection devices RBI to RB3.

The wireless connection device RBI has Zone 1 as its communication area.

Similarly, wireless connection devices RB2 and RB3 have zones 2 and 3 as their communication areas, respectively.

Subscriber circuits LCI to LC6 are each upper station (exchange)
connected to EXCH, and the telephone device L is connected to the upper station EXCH.
and 2 are stored.

Next, two aspects of the present invention will be explained with reference to the drawings.

Subscriber circuits LCI-LC6 are provided corresponding to mobile terminal radios Psi-PS6 located in zones 1-3, and mobile terminals PS1-PS6 can freely move between zones. Trunks 1 to 5 are provided corresponding to wireless lines.

In Tsumashi Zone 1, there are two wireless lines, and these wireless lines correspond to trunks TI and 2. Similarly, there are two wireless lines in zone 2, and these wireless lines correspond to trunks T3 and T4. On the other hand, the number of wireless lines used in the sea 73 is only one, and this wireless line corresponds to the trunk T5.

Trunk interface circuit TINF is connected to trunk T1
~5 and is connected to the trunk interface circuit TIN
F detects and stores information necessary for call processing such as location registration information sent from the mobile terminals PS1 to PS6.

The communication path control circuit SWC connects the trunks T1-5 and the subscriber circuits LCI-6 via the communication path section SW in accordance with instructions from the main control section CC and in response to calls.

Destination representation units #1 to #3 are connected to the location registration information transfer device LIS. Here, for example, destination display device 1 is placed at a workplace corresponding to sea 71, and destination display device 2 is placed at a workplace corresponding to sea 72. On the other hand, the second destination display device 3 is installed at a workplace outside the service zone.

The mobile terminal Psi~6 automatically (or manually) performs a location registration operation. When receiving an incoming call, the called mobile terminal performs a calling operation via a wireless line only to the zone in which it has already registered. For example, when the mobile terminal PS5 located in zone 2 registers its location in zone 2, the mobile terminal PS5 first acquires an empty wireless line within zone 2. At this time.

Assuming that the wireless line corresponding to trunk 4 is captured, terminal PS5 sends its own identification code ID5 through this captured wireless line. The sent identification code ID5 is input to the trunk interface circuit TINF via the trunk T4. Trunk T1-5
Since the correspondence between the trunk T4 and zones 1 to 3 is predetermined, the trunk interface circuit TINF
By receiving the terminal identification code ID5 from the mobile terminal PS5, it is learned that the mobile terminal PS5 is located in zone 2, and this is stored. When a call is received, the main control unit #CC reads the zone number in which the called mobile terminal PS5 is located through the trunk interface circuit TINF, and calls the required zone, that is, zone 2.

The location registration information transfer circuit LIS receives the location registration information stored in the trunk interface circuit TINF via the main controller CC. In other words, when the location registration information transfer device LIS requests the main controller CC for location registration information, the main controller CC reads the latest registration information of each mobile terminal from the trunk interface circuit TINF and sends the location registration information. Send to transfer device technician S. The location registration information is converted into a format suitable for display by the location registration information transfer device LIS and sent to the next destination display devices 1 to 3. Destination display devices 1-3 display the location zone of each mobile terminal PS1-PS5 based on the received location registration information.

By periodically repeating the above operations, the latest information on the location of the mobile terminal is always displayed on the first destination display devices 1 to 3. If the mobile terminal Psi~6 and the user are operated in correspondence with each other, the user's individual destination can be displayed. Further, each of the destination display devices 1 to 3 does not need to display the positions of all mobile terminals, and may display only the mobile terminals belonging to the workplace where the two destination display devices are installed.

〔Effect of the invention〕

In a portable cordless telephone system, the present invention utilizes a location register/stage required for call processing function to display the destination of a mobile terminal. This has the effect of making it possible to effectively utilize the telephone system and increasing the added value of the portable cordless telephone system.
