Ericsson Cloud Core Subscription Manager

Cloud Core Subscription Manager is the commercial realization of the 3GPP Network Functions UDM/ARPF and AUSF.

The Cloud Core Subscription Manager (CCSM) allows Operators to manage multiple user type (mIoT, eMBB, cMTC) ) through any access-type anchored to a 5G Core Network  as specified by 3GPP, providing:

  • User Identification Handling
  • Access and Mobility Management
  • Subscriber Data Management
  • Generation of 3GPP AKA Authentication Credentials.
  • Harmonized service experience for end user over different access technologies (2G/3G/4G/5G/WiFi) with service continuity,
  • Authentication for 3GPP access as specified in 3GPP AUSF NF
  • Unified authentication entry point for all devices via 3GPP AUSF NF

To provide this functionality, the CCSM uses subscription data (including authentication data) that is stored in CCDM and accessed via 3GPP Nudr.


Multi-access coexistence and smooth migration scenarios

Direct Rest/http interface of 5GC UDM NF with an existing HSS-FE

Consolidated subscription data model for all access types 2G/3G/4G and 5G (NR-SA, NR-NSA), including authentication credentials

Deployment Flexibility for network efficiency and operational cost reduction

3GPP Rel-15 UDM and AUSF deployable in a combined VNF or standalone

Dual Mode 4G/5G capabilities by introduction of HSS (EPC & IMS) and 5G EIR with flexible deployment as combined VNF or standalone

High performance and resilience

Most advanced mechanisms for resilience and redundancy, both on internal microservice level and network level with N+k redundancy
