Abstract
Methods, systems, and devices are described for decreasing user plane latency in a wireless communication system. This may include routing a portion of bearer traffic to or from a UE through a local or serving gateway, or within or between base stations, rather than via the core network. In some examples, techniques for selected internet protocol flow ultra-low latency (SIPFULL) for systems in which users may have subscribed to enhanced services may be employed. The network may, for instance, authorize SIPFULL functionalities for UEs per access point name (APN) based on individual services subscribed by the UE to improve overall quality of service (QoS). In some examples, a UEs latency requirements or SIPFULL authorizations may affect mobility operations.
