Subscription Management

Ericsson subscription management solutions authorize access to network services for multiple user types, ensuring service continuity across different access methods. They support both legacy (2G/3G/4G) products and container-based 5G network functions, providing subscriber data management, mobility management, user security and authentication (SIM and non-SIM based), access authorization, and service authorization.


Smooth evolution

Smooth evolution and co-existence of 2G/3G/4G/5G systems with interworking assurance: 

  • Interworking functions are in place to assure service continuity and end-user experience when moving across different accesses and network domains. 
  • Support for subscriber migration scenarios. 

High availability

High availability and overload protection mechanisms: 

  • The most advanced mechanisms for resilience and redundancy, both on internal and network levels. 
  • Cooperative load regulation between business engine node/functions and subscriber data repository. 

Deployment flexibility

Deployment flexibility for network efficiency and operational cost reductions: 

  • Virtualized or physical data deployment options for products in UDC, supporting both 2G/3G/4G and 5G NSA front-ends. 
  • Dual Mode 4G/5G support in CCSM (UDM/AUSF/HSS/EIR) in one VNF with common O&M, common infrastructure, and common orchestration. It includes a common authentication vector generation function for 4G and 5G.
