Study on Best Practice of PFCP
The present document identifies the scenarios where the PFCP interoperability needs to be further enhanced for existing function and specifies the corresponding requirements, identifies the key issues which impact the PFCP interoperability, analyses potential solutions to address the key issues.
PFCP used in 4G (e.g. on Sxa, Sxb, Sxc interfaces) and 5G (e.g. on N4, N16a interfaces) are both within scope of the study.
