Abstract

PURPOSE: To display the present position of an unauthorizedly used PHS terminal which is stolen or the like. CONSTITUTION: A data base 4 is provided with the position information and using state (permission/inhibition) of the PHS terminals 1 as subscriber data. The using state is normally in use enabling state and an exchange 3 executes a usual call processing when call origination from the PHS terminal 1 or the call termination of the PHS terminal 1 is preset. In the case of desiring to stop the use of the PHS terminal 1 due to a robbery or the like, the using state of the data base 4 is set to use inhibition. When the call origination from the PHS terminal 1 set to the use inhibition is present, the exchange 3 recognizes the terminal 1 as a use inhibited terminal from the using state of the data base 4 and interrupts a call origination processing. Further, the exchange 3 reads the position information having the data base and outputs the information of the present position. As a result, the present position of the PHS terminals 1 which is stolen or the like is cleared.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS (Personal Handy Phone System).

[0002]

2. Description of the Related Art As a countermeasure against theft of a wireless telephone, Japanese Patent Application Sho 6
No. 3-131580, when detecting a call from a stolen wireless telephone, notifies the wireless telephone of the theft,
The wireless telephone writes the contents of the theft notification and the telephone number dialed when the telephone station receives the theft notification in the memory and notifies the telephone number of the telephone number to force a call with the wireless telephone. I'm trying to disconnect or record the call.

[0003]

Although the above-mentioned conventional method can suspend the stolen wireless telephone,
I didn't know its current location.

It is an object of the present invention to provide a personal handyphone system which allows the user to know the current location of a stolen wireless telephone.

[0005]

The personal portable telephone system of the present invention is a personal handy phone system composed of a PHS terminal, a cell site, a database, and an exchange, and the database is the location information of the PHS terminal and use permission / prohibition. Having the information, the exchange reads the current position information from the database based on the terminal identification information from the PHS terminal when the power of the PHS terminal is turned on, and reads the use permission / prohibition information from the database, and when the use is permitted, normal call processing is performed. If the use is prohibited, call processing is not executed and the current position of the PHS terminal is output.

[0006]

Therefore, the current position of the PHS terminal which is illegally used due to theft or the like can be known.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a personal mobile phone system according to an embodiment of the present invention. Although there are actually a plurality of cell sites 2, only one is shown for convenience.

The database 4 uses PH as subscriber data.
The S terminal 1 has location information (information indicating in which cell site cell the cell is located, specifically, the terminal ID and cell site ID) and the usage state (permitted / prohibited).
Normally, the usage status is licensed, and the PHS terminal 1
If there is a call from PHS terminal 1 or an incoming call from PHS terminal 1, exchange 3
Performs normal call processing. PHS terminal 1 due to theft etc.
When it is desired to stop the use of, the use state of the database 4 is set to the use prohibited. When a call is made from the PHS terminal 1 whose use is prohibited, the exchange 3 sets the database 4
The call processing is interrupted by recognizing the prohibited terminal from the usage state of. Further, the exchange 3 reads the position information stored in the database 4 and outputs the information on the current position. As a result,
The current position of the PHS terminal 1 that was stolen or the like is found.

[0010]

As described above, according to the present invention, the database has the location information of the PHS terminal and the use permission / prohibition information, and the exchange also stores the terminal identification information from the PHS terminal when the power of the PHS terminal is turned on. In addition, the current position information and the use permission / prohibition information are read from the database, the normal call process is executed when the use is permitted, the call process is not executed when the use is prohibited, and the current position of the PHS terminal is output. As a result, in addition to suspending use of PHS terminals that were stolen,
Know the current location of the PHS terminal that was stolen.
