Abstract

Apparatus, and an associated method, for paging an access terminal in a radio communication system. Dynamic configuration and reconfiguration of a quick page message is provided. Its configuration is dependent upon paging load in the system. Hash values are selected and used pursuant to the configuration, and use, of the message. A first hash value is selected within a first range. And, a second hash value is selected within a second range. The second range from which the second hash value is selected does not include the first hash value.

Claims

1. A method of identifying a structure by which a page message is configured, said method comprising:

determining a quantity of page indicators per access terminal page to include in a page message;

generating the page message, wherein the page message comprises page indicator locations having page indicators and a field to indicate the quantity of page indicators per access terminal page, page indicator locations locatable using hash values, said page indicators at said page indicator locations being indicative of an access terminal page;

setting the field to a value to indicate the quantity of page indicators per access terminal page that are included in the page message; and

transmitting the page message on a paging channel.

2. The method of claim 1 wherein the field comprises a two-bit field of the page message.

3. The method of claim 1 wherein the page message comprises a thirty-five bit message and wherein the field comprises a near-end-positioned field of the thirty-five bit message.

4. The method of claim 1 wherein the value set at the field comprises a first logical value to indicate a first quantity of page indicators per access terminal page included in the page message.

5. The method of claim 4 wherein the value set at the field comprises a second logical value to indicate a second quantity of page indicators per access terminal page included in the page message.

6. The method of claim 5 wherein the value set at the field comprises a third logical value to indicate a third quantity of page indicators per access terminal page included in the page message.

7. The method of claim 6 wherein the value set at the field comprises a fourth logical value to indicate a fourth quantity of page indicators per access terminal page included in the page message.

8. The method of claim 1 wherein the page message includes a thirty-three bit portion for page indicators and the method further comprises:

populating the thirty-three bit portion with page indicators.

9. The method of claim 1 wherein the field comprises a bit-pair field.

10. The method of claim 9 wherein the page message comprises a thirty-five bit message and wherein the bit-pair field comprises a non-end-positioned bit-pair field.

11. The method of claim 10 wherein the bit-pair field comprises a pair of bit locations, the pair of bit locations including a bit location thereof, adjacent to an end-positioned bit location.

12. Apparatus for a structure by which a page message is configured, said apparatus comprising:

a determiner configured to determine a quantity of page indicators per access terminal page to include in a page message;

a page message generator to generate the page message, wherein the page message comprises page indicator locations having page indicators and a field to indicate the quantity of page indicators per access terminal page, page indicator locations locatable using hash values, said page indicators at said page indicator locations being indicative of an access terminal page;

a setter configured to set the field to be of a value to indicate the quantity of page indicators per access terminal page that are included in the page message; and

a transmitter to transmit the page message on a paging channel.

13. The apparatus of claim 12 wherein the field comprises a two-bit field of the page message.

14. In an access network entity that sends information, an improvement of apparatus for structuring a page message, said apparatus comprising:

a quantity determiner configured to determine a quantity of page indicators per access terminal page to include in a page message;

a page message generator configured to generate the page message, wherein the page message is structured to include page indicator locations having page indicators and a field to indicate the quantity of page indicators per access terminal page, said field populatable with a value to indicate the quantity of page indicators per access terminal page that are included in the page message, page indicator locations locatable using hash values, said page indicators at said page indicator locations being indicative of an access terminal page.

15. The apparatus of claim 14 wherein the field of the page message comprises a two-bit field.

16. The apparatus of claim 14 wherein the page message comprises a thirty-five bit message and wherein the field thereof comprises a non-end-positioned bit field of the thirty-five bit message.

17. The apparatus of claim 16 wherein the non-end-positioned bit field comprises a pair of bit locations of which a bit location thereof is positioned adjacent to an end-positioned bit location.

18. The apparatus of claim 17 wherein the pair of bit locations comprises a thirty-fourth bit location and a thirty-third bit location of the thirty-five bit message.

19. Apparatus for facilitating paging of an access terminal, said apparatus comprising:

a detector configured to detect delivery of a page message, wherein the page message comprises page indicator locations having page indicators and a field set to be of a value to indicate a quantity of page indicators per access terminal page that are included in the page message; and

a hash generator configured to receive the quantity of page indicators per access terminal page from the first detector and generate a number of page indicator locations based on the quantity and hash values, said page indicators at said page indicator locations being indicative of an access terminal page.
