Abstract
A wireless terminal is provided that can ensure security while gathering a communication history using little memory. The wireless terminal (200) has a secure ID generation unit (221) for generating a secure ID that includes a terminal ID, and a transmission unit (224) for broadcasting the secure ID generated by the secure ID generation unit (221). The secure ID generation unit (221) writes a different terminal ID for each transmission on a first portion of the secure ID, and, on a second portion of the secure ID, writes the terminal ID that had been written on the first portion of the secure ID transmitted immediately before as a link ID.
Claims8
A radio terminal comprising:
- a secure ID generation section that generates a secure ID that includes a terminal ID;
- and
- a transmission section that broadcasts the secure ID generated by the secure ID generation section,
- wherein the secure ID generation section writes the terminal ID that differs for each transmission in a first part of the secure ID, and, in a second part of the secure ID, writes the terminal ID that was written in the first part of the secure ID transmitted immediately before as a link ID.
A radio terminal comprising:
- a reception section that receives from another radio terminal a secure ID generated by that radio terminal;
- a history information storage section that records history information that is a reception history of the secure ID received by the reception section;
- a compression processing section that, when a terminal ID written in a first part of a certain secure ID received by the reception section and a link ID written in a second part of another secure ID received by the reception section match, determines that a transmission source of those two secure IDs is the same, and compresses and re-records in the history information storage section the history information of a plurality of secure IDs whose transmission source has been determined to be the same;
- and
- a base station communication section that transmits the history information recorded in the history information storage section to a base station.
An information recording method comprising the steps of:
- receiving from another radio terminal a secure ID generated by that radio terminal;
- recording history information that is a reception history of received the secure ID in a history information storage section;
- when a terminal ID written in a first part of a certain received the secure ID and a link ID written in a second part of another received the secure ID match, determining that a transmission source of those two secure IDs is the same;
- and
- compressing and re-recording in the history information storage section the history information of a plurality of the secure IDs whose transmission source has been determined to be the same.
