Low latency user plane radio links are substantially enhanced by 3GPP's NR and E-UTRAN radio technologies in Release 15. Mobility remains one of the key differentiators between 3GPP's technologies and other systems (e.g. systems that use unlicensed radio, or fixed networks). Hence it is important to network operators that mobility is effectively supported for the enhanced, low latency radio features.

As the Release 15 RAN enhancements are targeted at around 1 ms one-way radio interface latencies, this TR looks at architectural enhancements and solutions for networks where the transmission latency between the radio base station site and SGi can be around 0.1 ms to 1 ms latency (c.f. 20-200km of speed of light delay in optic fibre).

This Technical Report investigates the enhancement of EPC for low latency communication including device mobility, using the CUPS architecture.
