The communications system includes, a service permission level notifier configured to tell a service permission level for associated with a received signal level for permitting service acceptance from the reader/writer to the transponder, and an access controller configured to determine in the transponder whether the received signal level from the reader/writer is at the notified service permission level to determine accessibility to the transponder from the reader/writer.
Claims19
A first apparatus comprising:
- a communication circuit which is configured to communicate with a second apparatus;
- and
- a controller which is configured to control the first apparatus to:
- receive, from the second apparatus, a beacon frame including identification information written in the beacon frame;
- wherein the controller is further configured to determine whether the first apparatus is within a service area identified by said identification information, and
- wherein the service area, which is identified by said identification information written in the beacon frame, has an access range that is determined depending on a service, and a first service has a different service area than a second service.
A method for communicating between a first apparatus and a second apparatus, the method comprising:
- receiving, from the second apparatus, a beacon frame including identification information written in the beacon frame;
- and
- determining whether the first apparatus is within a service area identified by said identification information,
- wherein the service area, which is identified by said identification information written in the beacon frame, has an access range that is determined depending on a service, and a first service has a different service area than a second service.
A non-transitory computer readable medium storing instructions for communicating between a first apparatus and a second apparatus which, when executed, cause the first apparatus to:
- receive, from the second apparatus, a beacon frame including identification information written in the beacon frame;
- and
- determine whether the first apparatus is within a service area identified by said identification information,
- wherein the service area, which is identified by said identification information written in the beacon frame, has an access range that is determined depending on a service, and a first service has a different service area than a second service.
