摘要： Systems, methods and apparatus described herein include features that enable efficient management of keep-alive messages utilized to maintain IP addresses and/or PDN connections associated with idle data traffic channels. An access terminal may consolidate keep-alive messages for idle data traffic channels, reducing the number of keep-alive messages transmitted. An access terminal may select which idle data traffic channels to maintain, and may transmit a consolidated keep-alive message for associated IP addresses and/or PDN connections. Timers may be associated with PDN connections and sub-timers may be associated with IP addresses associated with a PDN connection. Keep-alive messages can be consolidated based on the timers, sub-timers and/or combination of timers and sub-timers. In a complementary method, a PDN gateway or other network node cooperates with access terminals to reduce network traffic. In another complementary method, the PDN gateway or other network node synchronizes the timers and/or sub-timers provided with an access terminal.

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： Aspects of the present disclosure provide techniques for preventing loss of IP continuity when transitioning between networks. Certain aspects provide methods that generally include initiating a first timer upon attempting to transition from a first RAT network to a second RAT network during an IP session and initiating a second timer if a channel in the second RAT network is successfully acquired. According to aspects, a device may transfer context of the IP session to the second RAT network if a session is successfully negotiated in the second network prior to expiration of the second timer and the first and second networks share a common core network for IP services.
摘要翻译：本公开的方面提供了用于在网络之间转换时防止IP连续性损失的技术。某些方面提供的方法通常包括在尝试在IP会话期间从第一RAT网络转换到第二RAT网络时启动第一定时器，并且如果成功获取了第二RAT网络中的信道，则启动第二定时器。根据方面，如果在第二定时器期满之前在第二网络中成功协商会话，并且第一和第二网络共享用于IP服务的公共核心网络，则设备可以将IP会话的上下文传送到第二RAT网络。

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。
