Abstract

Advertising in connection with handing off a cell from one cell to another may be facilitated by segregating communication descriptors into a common part that does not change in different types of cells and a unique part that changes in different types of cells. The unique parts may be advertised more frequently than the common parts.

Claims

1. A method comprising:

identifying a set of base stations that are of the same cell type for advertising;

segregating a communication descriptor into a common part that does not change in different types of cells and a unique part that changes in different types of cells; and

advertising the unique part and common part with different periodicities.

2. The method of claim 1 including encoding the unique part using type-length-value or abstract syntax notation one encoding to indicate parameter values.

3. The method of claim 1 including using indication bits to refer to pre-configured type definition.

4. The method of claim 1 including determining a representative base station for a plurality of cells of the same cell type.

5. The method of claim 4 including advertising only the difference between a base station and a representative base station.

6. The method of claim 1 including advertising a version number for a common part.

7. The method of claim 1 including immediately broadcasting changes to the unique part.

8. The method of claim 1 including advertising common parts for target base stations only when a mobile station was not previously connected, if the serving and target base stations are of the same type.

9. The method of claim 1 including changing the advertising frequency based on cell type.

10. The method of claim 9 including advertising with greater frequency for cells with a larger range than for cells with a smaller range.

11. A computer readable medium storing instructions executed by a computer to:

identify a set of base stations that are of the same cell type for advertising;

segregate a communication descriptor into a common part that does not change across different types of cells and a unique part that changes in different types of cells; and

advertise the unique part more frequently than the common part.

12. The medium of claim 11 further storing instructions to determine a representative base station for a plurality of cells of the same type.

13. The medium of claim 12 further storing instructions to advertise only the difference between a base station and the representative base station.

14. The medium of claim 11 further storing instructions to advertise common parts for target base stations only when a mobile station was not previously connected, if the serving and target base stations are of the same type.

15. The medium of claim 11 further storing instructions to change the advertising frequency based on cell type.

16. An apparatus comprising:

a control; and

a storage storing instructions to identify a set of base stations that are of the same cell type for advertising, segregate a communication descriptor into a common part that does not change in different types of cells and a unique part that changes in different types of cells, and advertise the unique part more frequently than the common part.

17. The apparatus of claim 16 wherein said apparatus is a macro-cell base station.

18. The apparatus of claim 16 wherein said apparatus is a network operation center.

19. The apparatus of claim 16, said control to identify a representative base station for a plurality of cells of the same cell type.

20. The apparatus of claim 19, said control to advertise only the difference between a base station and a representative base station.
