Abstract

A mobile station in a wireless communication system associates a plurality of context tags with corresponding reference information. The reference information may define a characteristic, such as the location of the mobile station or a time frame. The context tags assigns an easily defined term to the reference information. The mobile station may then run programs that refer to the context tags, and not specifically to the reference information.

Claims

1. A method of defining contextual information comprising:

obtaining reference information;

assigning an identifier tag to the reference information; and

storing the reference information correlating with the identifier tag.

2. The method of claim 1, further comprising executing a program using the stored identifier tag.

3. The method of claim 1, further comprising storing the correlated information in a mobile station.

4. The method of claim 1, further comprising defining a context tag based on location data.

5. The method of claim 1, further comprising defining a context tag based on time frame data.

6. The method of claim 2, further comprising retrieving all context tags referred to within the program.

7. The method of claim 2, further comprising storing the correlated reference information and identifier tag in a first location and executing the program in a second location, wherein the second location does not obtain the reference information.

8. The method of claim 7, further comprising the first location informing the second location of a state of the identifier tag.

9. A mobile station for use in a wireless communication system comprising:

a memory which stores a plurality of context tags and associated defining characteristics; and

a processor which executes programs based on the context tags which meet the current conditions.

10. The mobile station of claim 9, wherein the defining characteristics are location based.

11. The mobile station of claim 9, wherein the defining characteristics are time frame based.

12. The mobile station of claim 9, wherein the programs are obtained from memory.

13. The mobile station of claim 9, wherein the programs are obtained from the wireless web.

14. The mobile station of claim 9, wherein the programs do not have access to the defining characteristics of the context tags.

15. The mobile station of claim 9, wherein the memory informs the processor of the state of the context tags.
