Abstract: An apparatus and method for identifying a serving country using at least one system specific parameter comprising extracting the at least one system specific parameter from a forward link signal; determining whether the at least one system specific parameter maps to a unique country; and identifying the serving country for a call.

Abstract: An apparatus and method for a centrally managed handoff comprising originating a service using a first technology and connecting the service using the first technology; activating a second technology that is different from the first technology; receiving a first request for the handoff from the first technology to the second technology; sending a second request for the handoff from the first technology to the second technology, wherein the second request relates to the first request; receiving an acknowledgement that the second technology is available; implementing the handoff from the first technology to the second technology; and determining that the handoff is successfully implemented before terminating the first technology.

Abstract: Disclosed are systems, methods and computer program products for better system reselection (BSR) in a multi-system wireless communication environment. In one aspect, the BSR procedure provisions a mobile device to determine if a currently-registered wireless communication system is the most-preferred system among systems of a similar technology and among systems of different technologies identified in the device's combined preferred roaming list (PRL). The mobile device then activates an intra-system BSR timer if the currently-registered system is not the most-preferred system among systems of similar technology and an inter-system BSR timer if the currently-registered system is not the most-preferred system among systems of different technologies. Upon expiration of the intra-system BSR timer, the mobile device searches for a more-preferred system among systems of similar technology.

Abstract: A method and apparatus for channel acquisition using a mobile station include obtaining geographic information of at least one wireless communication systems using one or more systems, respectively. The one or more channels are prioritized on a preferred roaming list based on the geographic information, and it is determined whether any of the prioritized one or more channels on the preferred roaming list are also on a most recently used (MRU) list. The mobile station attempts to acquire at least one of the prioritized one or more channels that is also on the MRU list.

Abstract: Techniques to search for signals while in an out-of-service state are described. In an aspect, a network entity may collect information for wireless devices within a designated area, determine at least one search parameter (e.g., a scan rate) based on the collected information, and provide the search parameter(s) to wireless devices within the designated area. The wireless devices may perform searches for signals in accordance with the search parameter(s) when they are out of service. In another aspect, a wireless device may collect information related to out-of-service events encountered by the wireless device, send the collected information to the network entity, receive the search parameter(s) from the network entity, and perform searches in accordance with the search parameter(s) when out of service. In yet another aspect, the wireless device may determine the search parameter(s) based on the collected information.

Abstract: A channel scanning order is dynamically created, modified, selectively ignored, or combinations thereof based on historical data, motion information, context information, alert message systems, network reselection, or combinations thereof. If a less preferred network has served a mobile device longer than a threshold amount of time, acquisition of the less preferred network is attempted before attempting acquisition of a more preferred network.

Abstract: Methods and apparatus for out of service processing with varied behaviors. In an aspect, a method is provided for service acquisition. The method includes determining one or more conditions, wherein each condition is associated with at least one weight, detecting whether an out-of-service event has occurred, and if an out-of-service event is detected: identifying selected conditions and associated weights, and processing the associated weights to determine service acquisition “on” and “off” times. In an aspect, an apparatus includes condition logic configured to determine one or more conditions, wherein each condition is associated with at least one weight, and processing logic configured to detect whether an out-of-service event has occurred, and if an out-of-service event is detected, to identify selected conditions and associated weights, and process the associated weights to determine service acquisition “on” and “off” times.

Abstract: Systems and methodologies are described that facilitate optimum technology selection within multi-modal configurations. A multi-mode mobile device can select and/or utilize a particular technology, system and/or configuration to provide optimal quality of service (QOS) in terms of various characteristics. For instance, an optimum technology can be selected and employed for a service request based upon performance, cost, power consumption, interference levels, and the like. The multi-modal mobile device can obtain characteristics of a plurality of technologies during idle states. The characteristics can be analyzed in order to generate a QOS table that provides relative rankings of the plurality of technologies in terms of service request type and the obtained characteristics. The QOS table can be utilized to select an optimum technology upon initiation of a service request.
