23.2143GPPArchitecture enhancements for control and user plane separation of EPC nodesRelease 17TS

The present document specifies the overall stage 2 level functionality for control and user plane separation of EPC’s SGW, PGW and TDF. This enables a flexible placement of the separated control plane and user plane functions for supporting diverse deployment scenarios (e.g. central or distributed user plane function) without affecting the overall functionality provided by these EPC entities.
