Section: F.2.2 Local/Edge CHF deployment
Content: There is an option of distributing CCS functions in a distributed way by making available, a CHF instance and the Edge Enablement Server (EES) is located in the same Service Deployment Cluster. On this case the CHF instance selected may be the one physically closer to the EES. Therefore, the charging events would be generated through the CTF towards the CHF that is available at the Edge. This is depicted in in TS 32.257[ Telecommunication management; Charging management; Edge computing domain charging ]  [57] clause 4.2.3. Furthermore, there are other distributed models that can be used, for instance, the availability of NF(CTF), instead of using an EES, in the Service Deployment Cluster.
