Session Management Function(SMF)

SMF is a fundamental element of the 5G Service-Based Architecture (SBA). The SMF keeps trace of PDU sessions and QoS Flows in the 5GC for UEs and make sure their states and status are in sync between Network Functions in Control and User Planes.

It also receives PCC (Policy and Charging Control) Rules from PCF (Policy Charging Function) and convert PCC Rules into SDF Templates, QoS Profiles and QoS Rules for UPF, gNB and UE respectively for QoS Flows establishment, modification and release etc.

Key Benefits

IPLOOK's 5GC SMF

IPLOOK 5GC SMF builds upon the evolutions of the IPLOOK SGW solution in the 4G space and its evolution in the 4G architecture to evolve to CUPS to support a decomposed SGW-C as the central control plane entity that communicates over an Sx interface to the Distributed and intergrated user plane functions.
In the 5G architecture, SMF is responsible for session management with individual functions being supported on a per session basis. SMF allocates IP addresses to UEs, and selects and controls the UPF for data transfer. SMF also acts as the external point for all communication related to the various services offered and enabled in the user plane and how the policy and charging treatment for these services is applied and controlled.
