摘要：
A method for maintaining IP context during an inter RAT handover of a UE between an eHRPD network and an LTE network may include delaying a transfer of an Internet Protocol context for at least one active packet data network until an IP address for an attach (PDN) Packet Data Network has been assigned and in the case where the Internet Protocol address for the Attach Packet Data Network is not assigned, initiating a detach operation from the LTE network without the user equipment losing the Internet Protocol context of the at least one active Packet Data Network.

在UE在eHRPD网络和LTE网络之间的RAT间切换期间维护IP上下文的方法可以包括延迟用于至少一个活动分组数据网络的因特网协议上下文的传输，直到用于附着（PDN）的IP地址为止， 已经分配了分组数据网络，并且在未分配用于附接分组数据网络的因特网协议地址的情况下，从LTE网络发起分离操作，而用户设备丢失了至少一个活动分组数据的因特网协议上下文 网络。
