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.

First claim

What is claimed is:

1. A method of processing broadcast information on a mobile terminal, the method comprising:
receiving, at the mobile terminal, broadcast metadata associated with broadcast information, wherein the broadcast metadata is received separately from and before the broadcast information;
obtaining a location criterion and a time criterion for the broadcast information from the broadcast metadata;
determining, at the mobile terminal, whether to notify a user of the mobile terminal of the broadcast information using the location criterion, the time criterion and a probability threshold; and
skipping receiving the broadcast information responsive to determining that the user should not be notified of the broadcast information.

2. The method of claim 1 , further comprising:
obtaining the probability threshold from the user.

3. The method of claim 1 , further comprising:
obtaining the probability threshold from the broadcast metadata.

4. A method of processing broadcast information on a mobile terminal, the method comprising:
receiving, at the mobile terminal, broadcast metadata associated with broadcast information;
obtaining a location criterion and a time criterion for the broadcast information from the broadcast metadata;
determining a location of the mobile terminal;
determining a probability value based on the location criterion and the time criterion, wherein determining the probability value comprises determining a probability that the location of the mobile terminal meets the location criterion at a time corresponding to the time criterion; and
determining, at the mobile terminal, whether to notify a user of the mobile terminal of the broadcast information using the location criterion, the time criterion and a probability threshold, wherein determining whether to notify the user comprises comparing the probability value to the probability threshold.

5. The method of claim 4 , wherein determining the location of the mobile terminal comprises determining a prior location of the mobile terminal, or a present location of the mobile terminal, or a future location of the mobile terminal, or a combination thereof.

6. The method of claim 5 , wherein determining the location of the mobile terminal comprises:
determining the prior location of the mobile terminal using a history of locations of the mobile terminal; or
determining the future location of the mobile terminal using the history of locations of the mobile terminal.

7. The method of claim 4 , wherein:
the location criterion is a first location criterion;
the time criterion is a first time criterion;
the location of the mobile terminal is a first location;
the method further comprises:
obtaining a second location criterion and a second time criterion for the broadcast information from the broadcast metadata; and
determining a second location of mobile terminal; and
determining the probability value further comprises determining a probability that the second location of the mobile terminal meets the second location criterion at a second time corresponding to the second time criterion.

8. A mobile terminal comprising:
a processor configured to:
receive broadcast metadata associated with broadcast information, wherein the broadcast metadata is received separately from and before the broadcast information;
obtain a location criterion and a time criterion for the broadcast information from the broadcast metadata; and
determine whether to notify a user of the mobile terminal of the broadcast information using the location criterion, the time criterion and a probability threshold; and
skip receiving the broadcast information responsive to determining that the user should not be notified of the broadcast information.

9. The mobile terminal of claim 8 , wherein the processor is further configured to:
obtain the probability threshold from the user.

10. The mobile terminal of claim 8 , wherein the processor is further configured to:
obtain the probability threshold from the broadcast metadata.

11. A mobile terminal comprising:
a processor configured to:
receive broadcast metadata associated with broadcast information;
obtain a location criterion and a time criterion for the broadcast information from the broadcast metadata;
determine a location of the mobile terminal;
determine a probability value based on the location criterion and the time criterion by determining a probability that the location of the mobile terminal meets the location criterion at a time corresponding to the time criterion; and
determine whether to notify a user of the mobile terminal of the broadcast information using the location criterion, the time criterion and a probability threshold by comparing the probability value to the probability threshold.

12. The mobile terminal of claim 11 , wherein the processor is further configured to determine the location of the mobile terminal by determining a prior location of the mobile terminal, or a present location of the mobile terminal, or a future location of the mobile terminal, or a combination thereof.

13. The mobile terminal of claim 12 , wherein the processor is further configured to:
determine the prior location of the mobile terminal using a history of locations of the mobile terminal; and
determine the future location of the mobile terminal using the history of locations of the mobile terminal.

14. The mobile terminal of claim 11 , wherein:
the location criterion is a first location criterion;
the time criterion is a first time criterion;
the location of the mobile terminal is a first location;
the processor is further configured to:
obtain a second location criterion and a second time criterion for the broadcast information from the broadcast metadata; and
determine a second location of mobile terminal; and
determine the probability value further by determining a probability that the second location of the mobile terminal meets the second location criterion at a second time corresponding to the second time criterion.

15. A mobile terminal comprising:
means for receiving broadcast metadata associated with broadcast information, wherein the broadcast metadata is received separately from and before the broadcast information;
means for obtaining a location criterion and a time criterion for the broadcast information from the broadcast metadata;
means for determining whether to notify a user of the mobile terminal of the broadcast information using the location criterion, the time criterion and a probability threshold; and
means for skipping receiving the broadcast information responsive to determining that the user should not be notified of the broadcast information.

16. The mobile terminal of claim 15 , further comprising:
means for obtaining the probability threshold from the user.

17. The mobile terminal of claim 15 , further comprising:
means for obtaining the probability threshold from the broadcast metadata.

18. A mobile terminal comprising:
means for receiving broadcast metadata associated with broadcast information;
means for obtaining a location criterion and a time criterion for the broadcast information from the broadcast metadata;
means for determining a location of the mobile terminal;
means for determining a probability value based on the location criterion and the time criterion, wherein the means for determining the probability value comprises means for determining a probability that the location of the mobile terminal meets the location criterion at a time corresponding to the ti
