    摘要： 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.

    摘要： A method enables a user equipment (UE) intervention to reduce a network-initiated Quality of Service (QoS) interruption time or a disruption of the network-initiated QoS, while avoiding application intervention. The method includes communicating with a source radio access network (RAN) in accordance with a network-initiated quality of service (QoS) profile. The method also includes transferring to a target RAN. The method further includes triggering, by a user equipment (UE), a QoS setup to reestablish the QoS profile.

    摘要： Internet protocol (IP) continuity is fundamentally not possible when a user equipment (UE) moves from an evolved packet core (EPC) radio access technology (RAT) to a non-EPC RAT. However, there are instances when it is beneficial to not completely release an EPC IP context, such as when the UE moves to the non-EPC RAT for only a short period of time. The UE may retain an EPC IP context in a suspended state while the UE is in the non-EPC RAT, and revive the context when the UE returns to the EPC RAT. Accordingly, a method, an apparatus, and a computer program product for maintaining an EPC context at a UE are provided. The apparatus suspends and retains the EPC context when moving from an EPC capable network to a non-EPC capable network, and resumes the suspended EPC context upon returning to the EPC capable network.

    摘要翻译： 当用户设备（UE）从演进分组核心（EPC）无线电接入技术（RAT）移动到非EPC RAT时，因特网协议（IP）连续性基本上是不可能的。 然而，有时不能完全释放EPC IP上下文是有益的，例如当UE仅在短时间内移动到非EPC RAT时。 当UE处于非EPC RAT时，UE可以保持处于暂停状态的EPC IP上下文，并且当UE返回到EPC RAT时恢复上下文。 因此，提供了一种用于在UE处维护EPC上下文的方法，装置和计算机程序产品。 当从EPC能力网络移动到不支持EPC的网络时，该装置暂停并保留EPC上下文，并且在返回到EPC能力网络时恢复暂停的EPC上下文。

    摘要： 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.
