    摘要： Methods and apparatuses are provided that facilitate avoiding one or more wireless communication systems based at least in part on determining a level of unreliability of a reverse link channel related to a system. This can be based at least in part on determining whether the system can be accessed over the reverse link channel. If not, the wireless communication system can be avoided to conserve power utilized to perform such access attempts. Where the unreliability is temporary, however, some access attempts can be performed for systems of higher priority than a current system during the period of avoidance of one or more higher priority systems.

    摘要： Evolved High Rate Packet Data (eHRPD) network specific scanning process includes storing first network information indicating whether a channel frequency corresponds to an evolved High Rate Packet Data (eHRPD) network within a first persistent memory. The process also includes storing second network information indicating whether the channel frequency corresponds to a High Rate Packet Data (HRPD) network within a second persistent memory. The process further includes maintaining Internet Protocol (IP) continuity according to the first and second network information stored within the first and second persistent memories.

    摘要： Methods and apparatuses are provided that facilitate receiving signals from one or more base stations while communicating with a serving base station. Devices can receive the signals in autonomous gaps, during which the device can tune away to receive the signals. A device can report a low channel quality indicator (CQI) value to the serving base station prior to the autonomous gap to decrease a likelihood that the base station will schedule transmissions to the device, or at least decrease a data rate for transmissions. In another example, the device can report a CQI reserved for indicating starting an autonomous gap. In either case, the described methods and apparatuses can minimize data loss during the autonomous gap. Once the device returns from receiving the signals, the device can report an improved or actual CQI value to the base station to resume communications.

    摘要： A mobile device or access terminal of a wireless wide area network (WWAN) communication system is provisioned for Multi-Mode System Selection (MMSS) wherein an MMSS System Priority List (MSPL) is used with respect to the underlying system selection priority list (e.g., Private Land Mobile Network (PLMN) list). Relating a current location to one or more entries in an MMSS Location Associated Priority List (MLPLs) enables scaling a range of entries in the PLMN list, indicating whether the MSPL apply to the entire list of PLMNs stored in an access terminal or to some subset of the PLMN List. Similarly, the present innovation addresses whether the MSPL applies to the entire Preferred Roaming List (PRL) or some subset of a geo-spatial location (GEO) area.

    摘要： An access terminal pre-registers with a second access network via a first access network to ensure a quick handover in the future. Frequent pre-registration attempts are avoided by implementing a hysteresis timer that restricts when a pre-registration process can be initiated. The hysteresis timer is started when pre-registration is initiated by the access terminal. No new pre-registration attempts are permitted if the hysteresis timer has not expired. An abort condition can cause the hysteresis timer to be aborted early, and a new pre-registration can be initiated. Access points in the first access network may be grouped into one or more pre-registration zones. If the access terminal moves from a first access point to a second access point, a new pre-registration is skipped if the first and second access points have the same pre-registration zone or the second access point is aware of the pre-registration zone for the first access point.

    摘要： Aspects are described for redirecting wireless terminals between wireless networks. In a first embodiment, a coverage quality of user equipment within a first wireless network is monitored. Multiple candidate frequencies are then ascertained in response to the coverage quality to facilitate a communication between the user equipment and a second wireless network. The candidate frequencies are then communicated to the user equipment. In another embodiment, an indication of a plurality of candidate frequencies is received, and a failure in performing a handover from a first wireless network to a second wireless network is detected. For this embodiment, the handover is attempted via a primary frequency. An alternative frequency is then selected from the plurality of candidate frequencies in response to the failure, and a communication with the second wireless network is established via the alternative frequency.
