Abstract

A method in which an interrogator identifies a wireless tag under a management of a management server provided with steps; the interrogator performs registration application to the management server, the management server performs registration of the interrogator, the management server makes interrogator information, the management server controls start and end of carrier sense performed by the interrogator, the management server controls transmission and stop of a wireless signal performed by the interrogator, the management server makes the interrogator transmit the result of carrier sense, the interrogator transmits the result of carrier sense, and the management server makes interrogator interference information.

Claims

1. An identification method in which an interrogator identifies a wireless tag under a management of a management server comprising:

applying for a registration of the interrogator to the management server,

performing the registration of the interrogator,

making an interrogator information,

controlling start of carrier sense performed by the interrogator,

controlling end of carrier sense performed by the interrogator,

controlling transmission of a wireless signal performed by the interrogator,

controlling stop of a wireless signal performed by the interrogator,

transmitting the result of carrier sense to the management server, and

making an interrogator interference information.

4. An identification method according to claim 1 further comprising:

applying to the management server for a right to conduct wireless communication,

imparting the right to conduct wireless communication to the interrogator,

conducting wireless communication with the wireless tag,

returning the right to conduct wireless communication to the management server,

applying to the management server for cancellation of registration, and

deregistering the interrogator.

5. An identification method according to claim 4 further comprising:

suspending imparting of the right to conduct wireless communication to the interrogator, and

making a suspension information.

8. An identification method according to claim 1 further comprising:

applying to the management server for cancellation of registration, and

deregistering the interrogator.

9. An identification method according to claim 1 further comprising:

applying to the management server for a right to conduct wireless communication,

imparting the right to conduct wireless communication to the interrogator,

conducting wireless communication with the wireless tag, and

returning the right to conduct wireless communication to the management server.

10. An identification method according to claim 1 further comprising:

suspending imparting of the right to conduct wireless communication to the interrogator, and

making a suspension information.

11. An identification method according to claim 8 further comprising:

suspending imparting of the right to conduct wireless communication to the interrogator, and

making a suspension information.

12. An identification method according to claim 9 further comprising:

suspending imparting of the right to conduct wireless communication to the interrogator, and

making a suspension information.

2. An identification method in which an interrogator identifies a wireless tag under a management of a management server comprising:

applying to the management server for a right to conduct wireless communication,

imparting the right to conduct wireless communication to the interrogator,

conducting wireless communication with the wireless tag,

returning the right to conduct wireless communication to the management server,

applying to the management server for cancellation of registration, and

deregistering the interrogator.

3. An identification method according to claim 2 further comprising:

suspending imparting of the right to conduct wireless communication to the interrogator, and

making a suspension information.

6. An identification system comprising:

an interrogator which conducts wireless communication with a wireless tag and a management server which manages the interrogator,

wherein the interrogator includes;

a means for performing registration application to the management server;

a means for performing carrier sense;

a means for transmitting a result of the carrier sense to the management server;

a means for applying to the management server for a right to conduct wireless communication;

a means for starting wireless communication by obtaining the right to conduct wireless communication;

a means for returning the right to conduct wireless communication to the management server when wireless communication with the wireless tag is ended; and

a means for applying to the management server for cancellation of registration, and

wherein the management server includes;

a means for performing a registration of the interrogator;

a means for making an interrogator information;

a means for making the interrogator transmit and stop a wireless signal;

a means for making the interrogator start and stop carrier sense;

a means for making the interrogator transmit a result of carrier sense;

a means for making interrogator interference information;

a means for imparting the right to conduct wireless communication to the interrogator;

a means for suspending the imparting of the right to conduct wireless communication to the interrogator;

a means for making suspension information; and

a means for performing cancellation of registration of the interrogator.

7. An identification system comprising:

an interrogator which conducts wireless communication with a wireless tag and a management server which manages the interrogator,

wherein the interrogator includes;

a means for performing registration application to the management server;

a means for performing carrier sense;

a means for transmitting a result of the carrier sense to the management server;

a means for applying to the management server for a right to conduct wireless communication;

a means for starting wireless communication by obtaining the right to conduct wireless communication;

a means for returning the right to conduct wireless communication to the management server when wireless communication with the wireless tag is ended; and

a means for applying to the management server for cancellation of registration,

wherein the management server includes a recording medium, and

wherein the recording medium records a program by which the management server functions as;

a means for performing a registration of the interrogator,

a means for making an interrogator information,

a means for making the interrogator transmit and stop a wireless signal,

a means for making the interrogator start and stop carrier sense,

a means for making the interrogator transmit a result of carrier sense,

a means for making interrogator interference information,

a means for imparting the right to conduct wireless communication to the interrogator,

a means for suspending the imparting of the right to conduct wireless communication to the interrogator,

a means for making suspension information, and

a means for performing cancellation of registration of the interrogator.
