Abstract: Devices and methods are provided for supporting single carrier Radio Transmission Technology (1×RTT) and High Rate Packet Data (HRPD) neighbor lists over LTE, thereby enabling efficient scans for 3GPP2 neighbors with minimal interruption to the LTE operations both when idle or when in-traffic. In one embodiment, the method may involve accessing a neighbor list, each neighboring system in the list being prioritized based at least in part on whether the access terminal (AT) supports a hybrid mode. For example, the method may involve selecting the 3GPP2 system to handin to based at least in part on the neighbor list.

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.

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 translation: 接入终端经由第一接入网络向第二接入网预先注册以确保将来快速切换。 通过实施限制何时可以启动预注册过程的滞后定时器来避免频繁的预注册尝试。 当接入终端启动预注册时，启动滞后定时器。 如果迟滞定时器尚未到期，则不允许新的预注册尝试。 中断条件可能导致滞后定时器提前中止，并且可以启动新的预注册。 第一接入网络中的接入点可以被分组成一个或多个预注册区域。 如果接入终端从第一接入点移动到第二接入点，则如果第一和第二接入点具有相同的预注册区域或第二接入点知道预注册区域，则跳过新的预注册 为第一个接入点。

Abstract: Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Abstract: Systems, methods and apparatus for non-optimized handoffs for wireless communication are provided. For example, the disclosure may be applied to enhance non-optimized handoff from a long-term evolution (LTE) network to an evolved high rate packet data (eHRPD) network. Systems, methods, and apparatus for reducing the interruption gap during handoffs from an LTE radio access network to an eHRPD network are also discussed. In one aspect, a method is provided for communicating information associated with a handoff of a wireless device from a source network to a target network. The method includes, during a period of data inactivity, attaching to a first network and creating a context therewith, the first network being a non-preferred network as compared to a second network. The method also include connecting to the second network based on the context created with the first network and while maintaining at least a partial context with the first network.

Abstract: 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.

Abstract: Apparatus and methods are described herein for managing data network connections. When a gateway or user equipment receives a message indicating the active data network connections associated with the sending party, the gateway or user equipment checks a locally stored list of active data network connections to determine whether there is a match. If at least one active data network connection does not match, the receiving device sends a message to the sending party indicating the locally stored active data network connections.

Abstract: When a user equipment engaged in mobile communications transfers from a network with one radio access technology (RAT) to another network with a different radio access technology, maintaining continuity of location based services can improve system performance. A user equipment may perform a series of checks when undergoing inter-RAT transfer to determine if a location based services protocol used with the source network is operable on the target network. The UE also determines if location based services sessions are at a point where they can be continued following inter-RAT transfer. Where possible, protocols and sessions are maintained to preserve location based services continuity.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which 1×CSFB for communication of SMS messages in an LTE environment may be avoided. An IWS may receive a paging request message from a MSC, wherein the paging request message includes a first SMS service option indicating communication of a SMS message using a first RAT. The IWS may avoid an ESR procedure by analyzing the first SMS service option in the paging request message. Further the IWS may establish a common channel connection between the IWS and a target UE using a second RAT, wherein the first RAT and the second RAT are different.

Abstract: Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.

Abstract translation: 描述用于调度用于数据传输的逻辑信道的技术。 在一种设计中，用户设备（UE）配置有用于在上行链路上发送数据的多个逻辑信道。 每个逻辑信道与优先级和数据缓冲区大小相关联。 UE维护每个逻辑信道的令牌桶。 在每个调度间隔中，或者当接收到上行链路许可时，UE针对多个逻辑信道中的每个逻辑信道确定桶级（其可以是正值或非正值）。 UE确定具有相同极性的级别的逻辑信道，然后在具有相同的桶级极性的所有逻辑信道中标识具有相同优先级的逻辑信道。 基于每个识别的逻辑信道的数据缓冲器大小和/或桶级别，UE选择至少一个识别的逻辑信道进行调度。
