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过程来向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。

Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE) located at a public land mobile network PLMN border area may modify cell selection parameters in order to leave a current PLMN for a more favorable visitor PLMN (VPLMN). The UE may, for example, identify the border area by monitoring GPS coordinates, identifying a mobile country code (MCC) of a network, searching for a background PLMN after experiencing a number of transmit failures, or by detecting a high block error rate (BLER). Additionally or alternatively, the UE may have certain physical or environmental constraints that create an asymmetry in uplink/downlink conditions, and this asymmetry may be a basis for, or may be accounted for, in modifying cell selection parameters.

Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.

Abstract: Session initiation messages may be compressed using templates for evolved data compression scheme (eDCS). One or more session initiation messages may be exchanged between various network entities, such as UEs and base stations, for purposes such as registration, call setup, and call modification, for example. Session initiation messages may include header fields which identify the caller and characteristics of the device receiving the call, and may also contain payload, which describes the audio/video codec characteristics. Many of these contents may be repeated across all user devices of the same vendor attached to the same operator and may be compressed using templates to enhance system efficiency. These templates may be known at the transmitter and receiver, and reduce the data that has to be carried over air.

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: Certain aspects of the present disclosure relate to techniques for increasing the emergency call success rate by reducing the number of retries in a same domain. According to one aspect, a multi-mode user equipment may measure a first time period upon a first attempt of establishing an emergency call in a first RAT network. The UE may use a configurable parameter to determine a number of times that the UE may retry the emergency call in the first RAT network after expiration of the first time period without establishing the emergency call or after a failed attempt of the emergency call during the first time period. The UE may switch to a second RAT network if the UE fails in establishing the emergency call in the first RAT network after retrying the determined number of times.
