Abstract: Aspects disclosed herein relate to effectively handling failure and retry mechanisms during pre-registration for an eHRPD optimized handover. In one example, a UE may be equipped to detect one or more instances of failure during a pre-registration procedure as part of an optimized handover process. The UE may further be equipped to perform one or more pre-registration retry processes based on the detected one or more instances of failure. In one aspect, the one or more instances of failure may include any combination of a permanent LTE connection failure, a temporary LTE connection failure, a session negotiation failure, a virtual connection failure when bringing up a data call, a link control protocol (LCP) failure, etc.

Abstract: Aspects disclosed herein relate to enabling fallback to a second data service based on whether one or more fallback conditions are present before or during establishing a data context with a first data service. In one example, a UE may be configured to determine whether one or more fallback conditions are present before or during establishing a data session with a first data service. The UE may be further configured to prohibit further attempts to establish a data context to access the first data service based on the determination of the presence of at least one of the one or more fallback conditions. Some aspects disclosed herein relate to enabling fallback to a HRPD data service based on whether one or more fallback conditions are present before or during establishing a data context with an eHRPD data service.

Abstract: 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.

Abstract: Systems and methodologies are described that facilitate triggering multi-carrier requests at a mobile device and granting or denying the request at the access point. The mobile device can determine when to request additional carriers from the access point based on communication parameters, such as buffer levels, inflow/outflow data rates, PA headroom for handling an additional carrier, a timer for requesting the carrier, a maximum number of allocable carriers, and/or the like. Upon receiving the request, the access point can grant or deny the request based at least in part on subscriber level of the mobile device, available resources in the access point, reverse link throughput, and/or the like. Allocating additional carriers to the mobile device can increase throughput for communicating with the access point.

Abstract: 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.

Abstract: An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.

Abstract: This disclosure provides systems, methods and apparatus for non-optimized handoffs for wireless communication. 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 fetching a context for a device communicating via a first radio access system of a first network based in part on a unique identifier from a second radio access system of a second network.

Abstract: Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). 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.

Abstract translation: 这里描述了用于访问移动网络的分布式接入点管理。 作为示例，维持在毫微微小区基站（BS）的接口应用可以有助于对于毫微微用户终端（UT）的初始加电和/或获取。 在启动时，毫微微小区利用自举进程来向UT提供在特定地理区域（GEO）内建立至少一个BS作为高优先级的SDL。 因此，当毫微微UT在GEO内时，UT更有可能获得，驻留和/或切换到首选BS。 在GEO外部，服务接入点可以为Femto UT OTA提供适合具有不同高优先级接入点的另一个GEO的自定义SDL。 通过在分布式接入点实现接入点管理，可以减轻或避免昂贵的网络设备。
