Product Description

cnSGW-C is a Control Plane Network Function (NF) of the converged core network (4G-5GC). The Serving Gateway Control Plane Function (cnSGW-C) is built on top of the SMI architecture. cnSGW-C acts as a UE anchor and supports mobility procedures, along with session setup and termination procedures, as specified in 3GPP TS 23.401 and 3GPP TS 23.214.

The Serving Gateway Control Plane Function (cnSGW-C) provides the functionality of the S-GW as defined by TS 23.401 [2], except for the functions that are performed by the SGW-U, as described in 3GPP Spec 23.214 Table 4.3.2-1. In addition, the cnSGW-C is responsible for selecting the SGW-U (as described in 3GPP Spec 23.214 clause 4.3.3) and for controlling the SGW-U with respect to the functions described in TS 23.214 Table 4.3.2-1.

With SMF (IWF) support based on Cisco Cloud Native Platform, it is recommended to support cnSGW-C functionality on Cloud Native Platform for better hardware utilization and O&M activities.
