The objective is to study use cases and propose potential requirements for supporting traffic classification and service chain selection capabilities per operator's policy (e.g. based on user's profile, application type, RAN type, RAN status and flow direction) in order to realize efficient and flexible mobile service steering in the (S)Gi-LAN network.

Flexible Mobile Service Steering
In order to realize efficient and flexible mobile service steering in the (S)Gi-LAN, the MNO uses some information (e.g. user profile, RAT type, application characteristics, etc.) to define traffic steering policies. These policies are used to steer the MNO's subscriber's traffic data to appropriate enablers (e.g. NAT, FW) in (S)Gi-LAN.
The term (S)Gi-LAN used in the present document represents a system which is out of 3GPP scope.
