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.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus initiates a process for reselection from a first network (e.g., C2K) to a second network (e.g., LTE) by performing a measurement on a frequency indicated in a neighbor list received from a first cell in the first network. The neighbor list includes information indicating at least one frequency associated with the second network. The apparatus creates a state (e.g., starts an EUTRAReselect timer) associated with the frequency based on the measurement. The apparatus moves (e.g., performs an idle HO) from the first cell to a second cell in the first network. The apparatus determines whether to maintain the state upon the move from the first cell to the second cell.

摘要： Pre-registration involves establishing and maintaining the same Packet Data Network (PDN)/Quality of Service (QoS) context that exists in a 3GPP Long Term Evolution (LTE) network via a data tunnel in a 3GPP2 evolved High Rate Packet Data (eHRPD) network. To avoid undue increases in the traffic on a LTE Air Interface and core network, optimizations selectively complete the PDN context only for a subset of the PDN connections, only when close to performing a handover, or other trigger conditions.

摘要： 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.
摘要翻译：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。与传统的服务回收扫描程序相比，平均电流的降低可以实现：在5分钟的OOS标记，减少约45％，15分钟的OOS标记，约60％的减少和6小时 OOS标记，减少约50％。

摘要： 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.

摘要： Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

摘要： 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.
