Abstract: 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.

Abstract: Aspects of the present disclosure provide techniques and apparatus for improving user experience of a voice call associated with a simultaneous voice and long-term evolution (SV-LTE) device (e.g., improving silent redial during a mobile originated (MO) call or mobile terminated (MT) call by a SV-LTE device. A method for wireless communications by a user equipment (UE) capable of communicating via a first packet-based radio access technology (RAT) and a second circuit-switched RAT is provided. The method generally includes detecting initiation of a mobile originated (MO) call, attempting to establish a connection with the first RAT prior to sending a session initiation protocol (SIP) message for the MO call, determining whether the connection is successfully established, and, if the connection is successfully established, sending the SIP message. Numerous other aspects are provided.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a probability of occurrence of an event expected to occur within a period of time is determined, where the event comprises one or more of a tune-away event and a suspension event. One or more transmission control protocol parameters are manipulated before the occurrence of the event when the probability of occurrence exceeds a threshold to increase a retransmission time out parameter value, or to maintain a desirable congestion window size. The transmission control protocol parameters may be manipulated by delaying, duplicating or dropping acknowledgements and/or by selectively dropping received packets before, during, or after the event.

Abstract: Motion status states reported by an advanced motion detection process or other means of obtaining a movement state of Stationary or Non-Stationary from filtered accelerometer data are utilized to reacquire service during Out of Service scenarios. Both movement states operate in three power phases: aggressive scanning or normal power mode, slow scanning or moderate power mode, and deep sleep or power saving mode. The scanning rate, power mode, scanning period and/or channel list depend upon the movement state and power phase. Motion information obtained from an advanced motion detection process provides substantial improvements in service reacquisition performance and power consumption in stationary Out of Service scenarios. When compared to traditional service reacquisition scanning routines, the reductions in average current can be achieved of: at a 5-minute OOS mark, ~45% reduction, at a 15-minute OOS mark, ~60% reduction and at a 6-hour OOS mark, ~50% reduction.

Abstract translation: 通过高级运动检测过程报告的运动状态状态或从滤波的加速度计数据获得静止或非固定运动状态的其他方法被用于在停止服务情景期间重新获取服务。 两种移动状态都在三个功率阶段运行：积极扫描或正常功率模式，慢速扫描或中等功率模式，以及深度睡眠或省电模式。 扫描速率，功率模式，扫描周期和/或通道列表取决于移动状态和功率相位。 从高级运动检测过程获得的运动信息在固定的停止服务场景中提供了服务重新获取性能和功耗的实质性改进。 与传统的服务追溯扫描程序相比，平均电流的降低可以实现：在5分钟的OOS标记下，减少约45％的OOS标记，减少约60％，6小时 OOS标记，减少约50％。

Abstract: A method and apparatus for world-mode devices capable of managing technology selection for multimode roaming between existing access technologies, as well as possible future access technologies, in a manner that eliminates wasteful scanning for non-existent systems and reduces roaming charges is disclosed. The method allows the device an opportunity to reacquire its home system before scanning for available roaming network resources in a prioritized manner that mitigates roaming costs, while conserving power and acquisition delays by eliminating scanning for non-existent system types. A minimum OOS duration is imposed on a home system before acquisition of a roaming partner to provide more time to re-acquire the home system. Preferred partner scanning and acquisition reduces roaming charges, while scanning for non existent systems is eliminated altogether.

Abstract: Aspects of the present disclosure are directed to methods and apparatus for selective better system reselection for wireless devices capable of cell reselection. An apparatus for wireless communication is configured to receive a message from a current system, the message including a neighbor list having one or more neighbor systems. The apparatus compares the neighbor list to a local preferred systems list, and determine an existence of a preferred neighbor system in the local preferred systems list. The preferred neighbor system has higher priority than that of the neighbor systems in the neighbor list. The apparatus determines whether to perform Better System Reselect (BSR) for the preferred neighbor system instead of cell reselection based on the determination.

Abstract: Certain aspects of the present disclosure propose methods and apparatuses for reducing power consumption associated with performing reselection between radio access technologies (RATs). For example, a network that supports first and second RATs may obtain a list of neighbor base stations of a third RAT and determine whether to transmit the neighbor list on the first RAT, the second RAT, or both. In another aspect, a user equipment (UE) may combine information from the neighbor lists received from the first and the second RATs, and decide whether to take measurements in the third RAT based on the combined information. The UE may also maintain a central entity with measurements taken in the third RAT based on the neighbor lists received from the first and the second RATs and decide whether to perform cell reselection based on measurements in the central entity.

Abstract: Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.

Abstract: Systems and methodologies are described that facilitate avoidance of duplicative resource allocation and/or erroneous service charges via unambiguously indicating an entity responsible for quality of service (QoS) initiation. In one example, an indication is provided to a mobile device to indicate a preference for network-initiated QoS or a preference for device -initiated QoS. QoS for a data flow can be established in accordance with the indication. For instance, the mobile device initiates QoS when the indication specifies a preference for device-initiated QoS while a network establishes QoS when the indication specifies a preference for network-initiated QoS.
