    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.

    Abstract: A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems. New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system. A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.
