Abstract
An apparatus, and an associated methodology for a communication system in which an access terminal is paged by a page sent on a paging channel. Hashes are generated by a hash generator at an access network to identify where in the paging message that page indications are to be positioned. And, hashes are generated at the access terminal to identify where in a received page that page indications are located.
Claims21
An apparatus for an access network that generates a first page message on a first paging channel, said apparatus comprising:
- a page indication populator configured to populate the first page message with page indications in an available plurality of page indication locations;
- and
- a hasher configured to generate N hash values, each non-initial iteration of generation of a hash value from amongst values of the available page indication locations exclusive of any prior-generated hash value generated during a prior iteration, each hash value determinative of where said page indicator populates the first page message with a page.
An apparatus for an access terminal that receives a first page message on a first paging channel, said apparatus comprising:
- a hasher configured iteratively to generate N hash values, each non-initial iteration generative of a hash value from amongst values of available page indication locations exclusive of a prior-generated hash value generated during any prior iteration;
- and
- a page indication detector configured to detect values of page indications populating the first page message, hash values generated by said hasher used to identify to said page indication detector where in the first page message to detect the values of the page indications.
A method for facilitating paging of an access terminal that receives a first page message on a first paging channel, said method comprising:
- iteratively generating N hash values, each non-initial iteration generative of a hash value from amongst values of available page indication locations, exclusive of any prior-generated hash value generated during a prior iteration;
- and
- detecting values of page indications populating the first page message, generated hash values used to identify where in the first page message to detect the values of the page indications.
A method for facilitating generation, at an access network, of a first page message on a first paging channel, said method comprising:
- iteratively generating N hash values, each non-initial iteration generative of a hash value from amongst values of available page indication locations of the first page message exclusive of any prior-generated hash value generated during any prior iteration;
- and
- populating the first page message with page indications at page indication locations corresponding to hash values.
A method for determining page indication locations comprising the steps of:
- generating a first hash value;
- generating a second hash value;
- if the first hash value is not equal to the second hash value, determining a first page indication location based upon the first hash value and determining a second page indication location based upon the second hash value;
- and
- if the first hash value is equal to the second hash value, determining a first page indication location based upon the first hash value and using a predetermined location for the second page indication location.
