Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided. | 04-09-2009 |

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. | 03-25-2010 |

20100177629 | Protocol Fallback Technique for Wireless Data Communications - A wireless communications device is configured to establish a radio level session with a network at a relatively high or highest protocol level among a plurality of protocol levels supported. Upon failures in establishing, or during, a network level data session, the radio level session is closed. Thereafter, the device re-attempts to establish the network level session at a lower, fallback protocol level, by pretending it is a legacy device incapable of supporting the high protocol level. In this manner, the network is likely to follow a different procedure in establishing data communications, whereby an error that caused the failure is less likely to be repeated. As examples, error conditions in eHRPD data sessions result in fallback to HRPD or 1xRTT data sessions. A network based alternative embodiment implements protocol fallback via appropriate fallback instructions to the wireless device. | 07-15-2010 |

20100285789 | METHOD AND APPARATUS FOR CONTROLLING CARRIERS USED AT AN ACCESS TERMINAL - Carriers used at an access terminal may be selectively controlled by dynamically determining whether one or more carriers from which the access terminal receives data should be shut off based on one or more real-time conditions at the access terminal. Processing capabilities and memory usage at the access terminal are compared to predetermined thresholds to determine whether the one or more carriers should be shut off, whether entirely or partially. Shutting off a carrier may comprise reducing the number of slots (up to a total of all available slots) that a carrier may use to transmit data to the access terminal during a given time period. If it is determined that the one or more carriers should be entirely or partially shut off then the access terminal transmits a message notifying an access node to shut off the transmission of the one or more carriers to the access terminal. Since less data will be received, processing and/or memory capabilities may be directed to other applications. | 11-11-2010 |
