Handovers in a Third Generation Partnership Project (3GPP) 5G mobile network occur quite often. During handovers, user packets are buffered either at a user equipment (UE) level or at a network level. In 5G network scenarios, primarily those involving ultra-reliable low latency communication (URLLC) use cases, buffering user packets, as well as handover delays, are highly undesirable. Higher delays can be observed between inter-Radio Access Technology (RAT) handovers or between 3GPP and non-3GPP networks, due to longer handover procedures. Presented herein are techniques that may reduce the 5G handover latency for time sensitive applications through the use of a fast handover procedure.
