The scope is to study the mechanisms to address use cases dealing with policy driven selection of E-UTRA or NR based on certain criteria (e.g. for a given DNN or a QoS flow) associated with user applications by the core network.
  • Scenario 1: The E-UTRA access node and NG-RAN access node are connected to EPC and 5GC respectively.
  • Scenario 2: The E-UTRA access node and NR access node are connected to 5GC in a dual connectivity mode.
Potential area of study includes evaluating the mechanism available in 5G system as well as any potential enhancements that may improve the potential shortcomings identified by the study use cases.

RAN, while making use of the operator provided policies, is assumed to make final decision regarding handover/redirection/switching as RAN has the responsibility into radio and load conditions which govern the success of such a decision.
