Subscriber station with dynamic multi-mode service acquisition capability
First Claim
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.

Abstract
A system for providing a dynamic multi-mode service acquisition capability to a subscriber station is provided. The subscriber station is capable of operating in two or more modes of operation. A time to scan condition is indicated while the subscriber station is operating in a current mode of operation having active and inactive states. Responsive thereto, the system stores state information for the current mode of operation, and attempts at least a partial acquisition of communications services in accordance with another mode of operation. The at least partial acquisition attempt is scheduled to be initiated while the subscriber station is operating in the inactive state in the current mode of operation, and completed before the subscriber station transitions back to the active state in the current mode of operation. If the acquisition attempt is successful, the subscriber station transitions to the new mode of operation, maintaining appropriate registration. If unsuccessful, the subscriber station uses the stored state information to resume operating in the current mode of operation.

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. - View Dependent Claims (2, 3, 4, 5)

6. 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;
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 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, wherein the second logic determines when the subscriber station is scheduled to next transition to the active state in the current mode of operation, and, responsive thereto, determines one or more parameters of the at least partial acquisition; 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. - View Dependent Claims (7, 8, 9, 10)

11. A method of dynamically acquiring services in a subscriber station, the subscriber station capable of operating in two or more modes of operation, the method comprising:
-
indicating a time to scan condition while the subscriber station is operating in a current mode of operation having active and inactive states, wherein the time to scan condition is indicated responsive to sufficient proximity being detected between the subscriber station and a coverage area of a candidate system, and wherein the proximity detection is accomplished based on consideration of an estimated location of the subscriber station cell in relation to the coverage area of the candidate system;
storing, responsive to the indication of the time to scan condition, state information for the current mode of operation;
attempting responsive to the indication of the time to scan condition, at least a partial acquisition of communications services in accordance with the other mode of operation, the at least partial acquisition attempt scheduled to be initiated while the subscriber station is in the inactive state in the current mode of operation and completed before the subscriber station transitions back to the active state in the current mode of operation;
causing, if the at least partial acquisition attempt is successful, 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
allowing, if the at least partial acquisition attempt is unsuccessful, the subscriber station to resume operating in the current mode of operation using the stored state information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
