Network controlled filtering over wireless device communications
View Patent ↗There is stored in a memory an association between each n th one of N content types with a respective n th group of N groups of identifiers (N is an integer greater than one, n indexes from 1 to N, and at least one of the groups has more than one identifier). A beacon sender selects one of the content types for a beacon to be transmitted and selects a beacon identifier from the group associated with the selected content type. The beacon to be transmitted is compiled to include content of the selected content type and the selected beacon identifier. The beacon receiver selects at least one of the content types; and for a plurality of beacons received, filters out from further processing each beacon having a beacon identifier that is not within the group of identifiers associated with any of the at least one selected content types. The network creates the association and broadcasts it in a network cell.
