There are two methods, and a third method in which the wireless base station performs transmission and reception and the mobile terminal also performs transmission and reception.

As an example of the first conventional method,
Japanese Patent Application Laid-Open Publication No. 60-86700 discloses a "premise mobile object moving area regulation system".

[0008] In the method of the invention described in this publication, the moving object compares the recognition means for recognizing signal patterns from a plurality of radio base stations with the maximum intensity signal pattern and the signal pattern indicating its own access permitted area. And a warning means for issuing an alarm when the comparison result indicates a mismatch and restricting the entry into the non-entry area, and is a one-way signal transmission / reception from the radio base station to the mobile station.

[0009]

In the first, second and third prior art systems, the position of a permitting person is confirmed, a warning is issued when illegally entering a restricted area, and the illegal entering person is checked. However, there is a problem that the position confirmation cannot be checked at the same time.

[0010] Further, there has been a problem that the generation of the alarm cannot be changed with time.

[0011] An object of the present invention is to compare a management area identification signal with its own access permission area identification signal when a mobile station receives a management area identification signal from a fixed wireless base station. Providing a restricted-area notification system that can simultaneously issue a warning to confirm the location of a permitting person, issue a warning when illegally entering a restricted area, and simultaneously confirm the position of an illegal person. It is in.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a restricted area notification system according to the present invention, and FIG. 2 is a block diagram showing an example of the mobile station in FIG.

Referring to FIG. 1, a restricted access area notification system according to an embodiment of the present invention includes fixed wireless base stations 2A, 2A, 2A, 2B, which have wireless base station management areas 1A, 1B as signal arrival areas, respectively.
2B, mobile stations 3A and 3B carried by persons permitted to enter the wireless base station management areas 1A and 1B, and individual numbers received and stored from all fixed wireless base stations 2A and 2B. And a processing device 4 incorporating a personal computer or the like for performing predetermined processing based on the mobile device identification signal.

Then, each mobile unit 3 is, as shown in FIG.
A transmitting unit 35 and a receiving unit 31 for transmitting and receiving radio waves to and from a fixed wireless base station via the antenna 30; mobile station identification number data for identifying the own mobile station; and entry area identification signal data indicating an entry area. Storage unit 33 for storing
And a comparison unit 32 that compares the management area identification signal from the fixed radio base station received by the reception unit 31 with the own access permission area identification signal from the storage unit 33, and when the comparison result by the comparison unit 32 does not match. An alarm unit 34 for issuing an alarm.

Next, the operation of the present embodiment will be described.

The fixed wireless base stations 2A and 2B constantly transmit individual wireless base station identification signals (area IDs) Sa and Sc in order to clarify their own management areas.

When each of the mobile stations 3A and 3B is permitted to enter the radio base station control area, a separate entry permission identification signal (entry permission I) indicating its own entry permission area is provided.
D) Sp and a mobile station identification number (terminal ID) Sb for clarifying the own mobile station terminal.

Further, these terminal IDs are stored in the processing unit 4 together with the names of the owners when the owner of the mobile terminal, who has been permitted to enter each radio base station management area, enters the building. To register.

Here, the entry permission ID / Sp is written in accordance with the range of action when a person who is permitted entry is to work in a building. As a result, it is possible to change the action restriction range of the permitting person.

In this embodiment, since the mobile station 3A is prohibited from entering the radio base station management area 1A of the fixed radio base station 2A, it is assumed that the mobile station 3A does not have an entry permission ID.

In this state, the mobile station 3A enters the radio base station management area 1A and receives the area I from the fixed radio base station 2A.
When D · Sa is received, the mobile unit 3A's own comparison unit 32 determines that the access permission ID to the wireless base station management area 1A is not stored in the storage unit 33, and then issues an alarm to the alarm unit 34. Emits.

Thus, the person carrying the mobile station 3A can know that the radio base station management area 1A is a no-entry area.

At the same time, the mobile station 3A transmits its own terminal ID / Sb to the fixed radio base station 2A. When the fixed wireless base station 2A receives the terminal ID / Sb, if the terminal ID / Sb continues to be received for a preset time or more, the fixed wireless base station 2A issues an alarm to the processing device 4 and the wireless base station management area of the fixed wireless base station 2A. The maintenance person is notified that there is an illegal intruder in 1A.

At the same time, the processing device 4 receives the terminal ID / Sb from the fixed wireless base station 2A and determines that the illegal intruder is the mobile device 3A.

It is assumed that the mobile station 3B has an entry permission ID / Sp permitted to enter the radio base station management area 2A of the fixed radio base station 2B.
B enters the radio base station management area 1B of the fixed radio base station 2B and receives the area ID / Sc.
Since the comparison unit 32 determines that the access permission ID / Sp to the radio base station management area 1B is stored in the storage unit 33, the comparison unit 32 can pass through the radio base station management area 1B.

In the present embodiment, the number of radio base station management areas (fixed radio base stations) and the number of mobile stations are each two, but neither is limited to this number.
