DISCOVERY AND SUPPORT OF PROXIMITY

摘要

Systems, apparatus and methods for proximity determination between transceivers, such as mobile devices, are presented. Proximity may be a logical combination of geographic proximity, radio proximity and/or cellular proximity. Proximity may be determined using a low overhead coarse test followed by a more intensive accurate test. Proximity may be determined indirectly via one or more intermediary transceivers having a predetermined relationship.

主权项

1. A method, in a mobile device, to determine a combined proximity result for two transceivers, the method comprising:
determining results for at least two types of proximity from a group comprising:
geographic proximity;radio proximity; andcellular proximity; and determining the combined proximity result by logically combining the results for the at least two types of proximity.
