Abstract:
1. A system for providing a dynamic multi-mode service acquisition capability to a subscriber station, the subscriber station capable of operating in two or more modes of operation, the system comprising: first logic for indicating a time to scan condition while the subscriber station is operating in a current mode of operation having active and inactive states, the time to scan condition is indicated responsive to sufficient proximity being detected between the subscriber station and coverage area of a candidate system, wherein the proximity detection is accomplished based on consideration of an estimated location of the subscriber station in relation to the coverage area of the candidate system; second logic for, responsive to the first logic, indicating a time to scan condition storing state information for the current mode of operation and attempting at least a partial acquisition of communications services from a candidate system in accordance with another mode of operation, the at least partial acquisition attempt initiated while the subscriber station is in the inactive state in the current mode of operation and scheduled to be accomplished before the subscriber station transitions back to the active state in the current mode of operation; and third logic for, if the at least partial acquisition attempt is successful, causing the subscriber station to cease operating in accordance with the current mode of operation and begin operating in accordance with the other mode of operation, and for, if the at least partial acquisition attempt is unsuccessful, allowing the subscriber station to use the stored state information to resume operating in the current mode of operation.
