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： Apparatus and methods are described herein for efficiently handing over a user equipment from an earlier-technology network back to a later-technology network upon detecting the end of a coverage hole in the later-technology network. The UE may be configured to measure signals from the later-technology network. When the UE discovers, upon establishment or reestablishment of a PS data connection, that the later-technology network signal exceeds a defined threshold, the UE may initiate a handover back to the later-technology network.

摘要： Techniques for enabling a user equipment (UE) to return to a wireless network after failure to obtain a particular service (e.g., voice service) are described. The UE may determine that the wireless network does not support the particular service at a first location (e.g., the current UE location). In response, the UE may disable the wireless network and may refrain from attempting to obtain the particular service (or possibly any service) from the wireless network. The UE may thereafter re-enable the wireless network based on a trigger, which may result from a timer, an event, or broadcast information from another wireless network. After re-enabling the wireless network, the UE may perform cell search and system selection and may detect and select the wireless network. The UE may determine that the wireless network supports the particular service at a second location and may obtain the particular service from the wireless network.

摘要： Certain aspects of the disclosure relate generally to search of radio access technologies (RAT). For example, certain aspects of the present disclosure relate to a technique for performing higher priority radio access technology (RAT) searches in areas having a plurality of overlapping RATs, such as Global System for Mobile communications (GSM) and Long Term Evolution (LTE). According to certain aspects, a user equipment (UE) may be configured to periodically search for higher priority RATs in neighboring cells. According to certain aspects, upon finding a higher priority RAT cell, the UE may be further configured to evaluate, or “pre-evaluate”, criteria for cell reselection from found cell to the currently camped cell, while still camped on the current cell. The UE may be configured to decide whether or not to switch to the found cell based on the evaluation.

摘要： 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.

摘要： A method of processing a sequence of digital symbols comprises the steps of processing the sequence of digital symbols and determining an uncertainty in the processing. If the uncertainty exceeds a predetermined threshold, then the method further comprises the steps of processing at least two sequences of digital symbols wherein at least one parameter is set differently in each sequence, and deciding upon a calculated error for each sequence which sequence is used to generate an output signal.

摘要： Circuit-switched fallback (CSFB) is a technique to deliver voice-services to a mobile, when the mobile is camped in a long-term evolution (LTE) network. This may be required when the LTE network does not support voice services natively. If a user makes a mobile originating (MO) call, or receives a mobile terminating (MT) call, the UE may inform the LTE network that the UE is leaving for the call by initiating a call setup procedure. However, there may be instances where the call setup procedure may fail. If the call setup procedure was either not initiated, or was initiated but failed, the UE may determine to search for a suitable CS RAT/cell on its own without instructions/commands from the network. Therefore, certain aspects of the present disclosure provide techniques for the UE to find CS services based on information collected at the UE.

摘要翻译： 当移动台驻扎在长期演进（LTE）网络中时，电路交换回退（CSFB）是一种向移动设备提供语音服务的技术。 当LTE网络本身不支持语音服务时，可能需要这样做。 如果用户进行移动发起（MO）呼叫或接收移动终止（MT）呼叫，则UE可以通过发起呼叫建立过程来通知LTE网络UE正在进行呼叫。 但是，可能存在呼叫建立过程可能失败的情况。 如果呼叫建立过程未被发起或被发起但失败，则UE可以确定自己搜索合适的CS RAT /小区而没有来自网络的指令/命令。 因此，本公开的某些方面提供了用于UE基于在UE处收集的信息来找到CS服务的技术。

摘要： Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.
