CONTENTION-BASED DISCOVERY AND SECURE RANGING TECHNIQUES FOR CONGESTED ENVIRONMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17931072 titled 'CONTENTION-BASED DISCOVERY AND SECURE RANGING TECHNIQUES FOR CONGESTED ENVIRONMENTS
Simplified Explanation
- The patent application describes a method for a mobile device to receive polling messages from access devices during a polling phase. - The mobile device selects a timeslot during a response phase to transmit a response message. - During a third phase, the mobile device receives an assignment message with an assigned timeslot for a future session. - The mobile device performs secure ranging with access devices during the future session using the assigned timeslot. - The mobile device provides an access credential to the access devices based on the location determined using secure ranging.
Original Abstract Submitted
A mobile device may receive a plurality of polling messages with each polling message including an identifier of a particular access device transmitting the polling message. Each polling message of the plurality of polling messages may be transmitted during a polling phase. The mobile device may select a timeslot of a response phase of a communication session. The mobile device may transmit a response message during the timeslot of the response phase. The mobile device may receive, during a third phase, an assignment message including an assigned timeslot for a response phase of a future session. The mobile device may perform secure ranging with one or more access devices of the plurality of access devices during the future session using the assigned timeslot. The mobile device may provide an access credential to the one or more access devices based on a location determined using the secure ranging.
