摘要： 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.

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.
摘要翻译：本文公开的方面涉及基于在与第一数据服务建立数据上下文之间或期间是否存在一个或多个回退条件来使得能够回退到第二数据服务。在一个示例中，UE可以被配置为在建立与第一数据服务的数据会话之前或期间确定是否存在一个或多个回退条件。 UE可以被进一步配置成基于确定一个或多个回退条件中的至少一个的进一步被配置为禁止进一步尝试建立数据上下文以访问第一数据服务。本文公开的一些方面涉及基于在用eHRPD数据服务建立数据上下文之前或期间是否存在一个或多个回退条件来允许HRPD数据服务的回退。

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.
摘要翻译：本文公开的方面涉及在eHRPD优化切换的预注册期间有效地处理故障和重试机制。在一个示例中，UE可以被配备为在预注册过程期间检测一个或多个故障实例，作为优化的切换过程的一部分。 UE还可以被配备为基于检测到的一个或多个故障实例来执行一个或多个预注册重试过程。在一个方面，一个或多个故障实例可以包括永久性LTE连接故障，临时LTE连接故障，会话协商失败，提起数据呼叫时的虚拟连接故障，链路控制协议（LCP ）失败等
