The present document studies possible candidate protocols for the user plane in 5GC based on Rel-16 stage 2 requirements.
This technical report covers the following analysis:
List architectural requirements and key issues;
Identify the possible candidate protocols for user-plane including GTP-U as existing protocol, specified for Rel-15;
Define a list of evaluation criteria based on Rel-16 stage 2 architecture and procedures to evaluate the candidate protocols;
Evaluate the candidate solutions against the list of requirements and the potential benefits against the existing user plane solution in 5GS.
