Location and time based filtering of broadcast information
First Claim
1. A method of sending broadcast information, comprising:
- determining broadcast metadata for broadcast information, the broadcast metadata comprising location and time criteria and a probability threshold, used by terminals to filter the broadcast information, wherein the broadcast metadata is associated with the broadcast information; and
sending the broadcast metadata and the broadcast information to the terminals.

Abstract
Techniques for sending and receiving broadcast information are described. In an aspect, broadcast metadata may be generated for broadcast information and may include location and time criteria used by terminals to filter the broadcast information. Each location and time criterion may include (i) a location criterion given by a target location and a presence or absence requirement and (ii) a time criterion given by a time period in which the location criterion applies. A terminal may receive the broadcast metadata prior to or with the broadcast information, obtain location and time criteria from the broadcast metadata, and filter the broadcast information based on the location and time criteria. The terminal may evaluate each location and time criterion by determining its location within a specified time period and determining whether its location is within or outside a specified target location, as indicated by the presence or absence requirement.
