Abstract:
1. A method for modifying a data-synchronization interval used in operation by an access terminal, the method comprising: an access terminal, operating in a coverage area of a wireless access point, periodically polling at least one network device via the access point for synchronization data according to a first data-synchronization interval, wherein synchronization data comprises data selected from the group consisting of new data and updated data; the access terminal receiving from the access point information indicative of a number of access terminals being served by the access point in the coverage area; subsequent to receiving the information, the access terminal making an interval-modification determination comprising a determination of a second data-synchronization interval based at least in part on a comparison of the number to a threshold value, the second data-synchronization interval being different in duration than the first; and subsequent to determining the second data-synchronization interval, the access terminal periodically polling the at least one network device for synchronization data according to the second data-synchronization interval.
