JPS5831144B2 - Tracking phone method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tracking telephone system, and more particularly to a tracking telephone switching system that automatically connects an incoming call to a telephone closest to the destination as the called party moves.

Currently, the number of general subscriber telephone lines in Japan has reached more than 3 children, in all parts of the country.

It is widely used as a simple means of communication between fixed points.

However, as social activities become more widespread, the destination of the called party becomes unclear due to the expanded range of activities.

In many cases, conventional fixed-line telephones alone cannot function as a means of making quick calls.

The present invention aims to solve this inconvenience.

from a radio transmitter terminal carried by a called party who moves from place to place.
Sends information regarding the current location of the called party to a wireless receiving base station installed to support the telephone.

By storing that information within the exchange.

This system automatically connects an incoming call to the called party to the nearest telephone set, and will be explained in detail below with reference to the drawings.

The figure shows the configuration of an embodiment of the present invention. In the figure, 1 is a switch, 2 is
and 3 are telephones housed in the exchange 1, respectively.

Reference numerals 4 and 5 indicate radio reception base stations (hereinafter referred to as "base stations") installed corresponding to the telephones 2 and 3.

In some cases, this support can be applied to multiple phones at once.
This may be supported by one base station or vice versa.

Areas A and B. Each represents the reception service area of base stations 4 and 5.

Reference numeral 6 denotes a radio transmitter terminal (hereinafter referred to as "terminal") carried by a called party who moves from place to place.

Each terminal has a unique terminal number corresponding to the terminal.

7 and 8 are subscriber telephone lines (hereinafter referred to as "lines") connecting the telephones 2 and 3 and the exchange 1.

The figure shows a case where the terminal 6 carried by the called party is in area A.

The terminal 6 automatically sends a signal containing its own terminal number to the base station 4, for example, at fixed time intervals T1.

The base station 4 receives the terminal number sent from the terminal 6, notifies the terminal number through one line 7, and transmits the telephone number of the telephone 2 or information in place of this.

Note that the withdrawal of the telephone number of the telephone 2 may include the exchange 1 identifying the telephone 2.

The exchange 1 has a memory corresponding to the terminal number.

When the terminal number of the terminal 6 is transmitted from the base station 4, the telephone number of the telephone 2 is determined from the accommodation position of one line 7, and is stored in the memory together with the terminal number.

As described above, the operation from when a terminal sends a signal until it is stored by the exchange is called "location registration."

Note that the information to be stored does not have to be a telephone number, but information such as accommodation location information.

Of course, any information that replaces this can be used.

As a result of the above operations, when the terminal 6 is within area A, location registration is repeated through the base station 4 and line 7 every hour T1, but due to power outage of the terminal 6, etc., the time has elapsed since the last location registration. If the next location registration is not performed even after time T2, which is longer than T1, has elapsed, the location information regarding the terminal is deleted from the memory.

Note that, depending on the case, a method may be adopted in which the terminal automatically or manually sends out a signal for erasing the memory when the power is turned off.

Alternatively, a method that does not perform memory erasing may be used.

When an incoming call occurs to the terminal number of terminal 6 in this state, exchange 1 refers to the telephone number of telephone 2 stored in memory or information in place of this and transfers the incoming call to line 7.
By connecting to the telephone set 2, the bell of the telephone set 2 rings, and the called party can make a telephone call from the nearest telephone set 2.

If the called party moves and the terminal 6 moves into area B, the signal sent from the terminal 6 will be received by the base station 5, so the same procedure as in area A will be applied. As a result of the operation, location registration is performed through the base station 51 line 8, and the exchange 1 stores the terminal number and the telephone number of the telephone 3 or information in place of this in its memory, and sends an incoming call to the nearest telephone. It is possible to connect to 3.

Above, we have explained the case where the base station and the exchange are connected by a subscriber's telephone line, but depending on the method.

Needless to say, it is possible to connect a base station and an exchange through a dedicated line, or to condense a plurality of base stations and then connect them through a data line.

Further, the switching equipment having the above-mentioned memory is not limited to a switching equipment accommodating subscribers, but may also be provided in a centralized switching equipment in which the memory function is centralized.

According to the system of the present invention, as explained above, it is possible to automatically connect an incoming call to the telephone closest to the called party's destination, so that the called party can receive a call that is scheduled in advance. You will be able to act freely without worrying about incoming calls, etc.

By setting the number of base stations appropriately according to the size of the callee's activity range, the system of the present invention can be used for applications ranging from small-scale base stations within the same building to large-scale base stations that span different exchanges. up to 1
It is applicable to various things.

In addition, in the case of the method of the present invention, the terminal only needs to have a radio wave transmission function, so the configuration is relatively simple, and furthermore, since the transmitter operates intermittently every time T,
It has the advantage that the power supply capacity of the terminal is small.
