    • Described aspects provide for improving the mobility of wireless communication devices between one network domain and another network domain, specifically, but not limited to, between a Wireless Local Area Network (WLAN) and a cellular network and the like. Present aspects provide for services to be moved seamlessly and in a reliable manner between the cellular and WLAN domains in order to minimize service disruption for the end user and provide the requisite Quality of Service (QoS) for the different applications. The aspects herein presented provide for various mechanisms that serve to improve the decision points related to when and what technology each service is expected to be associated with and provides better techniques to move the wireless communication device between cellular and WLAN domains when in-traffic and when idle.

    • 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.
    • 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,该设备暂停并保留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。
