Abstract: Apparatus and methods for low power sensing of wireless access technologies are disclosed. In particular, a mobile wireless device, such as an access terminal, may utilize a lower power circuitry portion that operates at a lower power than active circuitry, such as a primary transceiver. The lower power circuitry portion includes a configurable searcher that is capable of sensing if signals of one or more various wireless access technologies are present. When the wireless device utilizes sleep or idle modes for power savings, use of the lower power sensing circuitry to sense the presence of wireless access technologies, rather than using an awoken higher power primary transceiver for sensing, affords increased power savings. An added ability of the lower power circuitry to be put into sleep or idles modes achieves even greater power savings.

Abstract: A method and an apparatus for system acquisition at a wireless device while maintaining a predetermined battery life span, include determining a level of remaining battery power upon entering an out of service state. A duty cycle, comprising a search time and sleep time, of acquisition attempts is determined such that the level of remaining battery power lasts for the defined battery life span. The duty cycle is determined by adjusting at least one of the search time and the sleep time, depending on how long the remaining battery power is required to last.

Abstract: A multimode wireless communication device utilizes location information provided by a co-located autonomous position location receiver to determine a preferred provider database and associated operating mode and operating technology when an out-of-service condition is encountered. The multimode wireless communication device can utilize active preferred provider database while in service and while acquired within a network. The multimode wireless communication device can initiate location-based mode and technology control when in an out-of-service condition. The multimode wireless communication device determines its location and based on the location, accesses a database to determine a preferred provider database. The preferred provider database provides a hierarchical list of available systems and associated information for acquiring and registering with the systems.

Abstract: A wireless communication device configured for automatic selection of geographic specific behavior is described. The circuitry is configured to receive a message with system information from the network that is mandatorily sent from a base station. The circuitry is also configured to determine the geographic area from the system information using a lookup table.
