Ericsson User Data Consolidation

Simplifying the complexity of managing subscription data in modern customer-centric telecommunication networks.


Subscriber Data Management (SDM) solutions lay in the heart of modern telecommunication networks providing identity management and granting users access to the different network services. As communications services evolve, for example with the introduction of VoLTE, Wi-Fi calling or NB-IoT; more database capacity and in many cases even new types of databases are required in the network. In a silo-based network, this implies more complexity leading to a higher Total Cost of Ownership (TCO) and a more fragmented view of a customer’s data.

With the Ericsson User Data Consolidation (UDC) solution we turn silos into a unified solution. The Ericsson UDC solution deliveries a state-of-the-art implementation of Data Layered Architecture (DLA) technology providing more efficiency to manage the data having the users and not individual types of accesses or services, into focus. This is what we at Ericsson call Customer-Centric Networks.

In a Customer-Centric Network, efficiency is key. The UDC solution eliminates the complexity of managing subscription by consolidating subscriber information from the different network silos into one common repository, creating a Unified Profile. This allows for a simpler and more scalable network topology, more efficiency on managing the network database resources and it also gives more flexibility to introduce new services.

Leveraging the Unified Profile, UDC enables a more complete view of the customer base facilitating the monetization of the data asset and to grow revenue through innovative use cases. Thanks to its embedded analytics and exposure capabilities UDC makes available in an agile way the required knowledge of your customer base that is crucial to delivering better customized services.
Security and availability are some of the most important robustness aspects that an SDM solution needs to cater to. The Ericsson UDC, apart from offering the most advanced replication mechanisms to secure that data is trustable at all times, also provides the most advanced mechanisms for resilience and redundancy following telecom market standards. UDC provides a unique state-of-art overload protection and load regulation solution that allows an e2e  congestion control by means of a real-time cooperation mechanism between the Back End and the most critical Ericsson application Front Ends to maximize the database performance under signalling storms.

The main benefits of a UDC empowered Customer-Centric Network are:

  • Optimized data management solution with significant TCO savings
  • Flexibility for native deployment and/or as Network Function Virtualization (NFV)
  • Shorter time to launch new services
  • Easy to monetize the data asset
  • High-performance and Telco-grade
  • Highly available and redundant
  • Unique protection from signalling overloads
  • Data consistency and durability in all network conditions
  • Flexible integration of different app-FE
  • High scalability and deployment flexibility
  • Unique customer experience with seamless services continuity between different accesses
  • Proven multi-vendor capabilities
  • Extensive deployment experience

UDC components

The Ericsson UDC solution is composed of the following. Click on the links for more information on each component.

Back End; Ericsson Centralized User Database (CUDB): A flexible high-capacity, highly robust and high-performance database that consolidates subscriber profile data from all users and IoT devices in the network avoiding data duplication and inconsistency. Being able to store profile data for 2G, 3G, 4G, 5G EPC, IMS, VoLTE, Wi-Fi, Fixed and IoT as well policing and charging data between others, the CUDB is a very flexible and scalable distributed database system that offers excellent TCO figures and that can boost the Time-to-Market (TTM) for new services launch in your network.

Application Front Ends: The Ericsson UDC is a multi-application system and our portfolio embraces the most common subscription and device management applications Front Ends like HLR, HSS, AUC, MNP, AAA, ENUM, PCRF and EIR. Thanks to the CUDB flexibility, it is also possible to integrated others Telecom and IT application Front Ends, both from Ericsson or from other vendors making it a very flexible and cost efficient solution to support new network’s needs.

Provisioning Gateway; Ericsson Dynamic Activation (EDA): The single point of provisioning which allows a simplified and efficient provisioning flow to all services and that secures the validation and integrity of the provisioned data into the system improving service provisioning time.

Analytics & Exposure; Ericsson User Profile Gateway (UPG): Adding embedded data analytics and exposure capabilities to the UDC system the UPG component unlocks the value of the data asset by offering a simpler and quicker visualization of a customer’s data stored in the system. It allows not only to generate new revenue with more personalized services but also protecting existing revenue by getting a better insight into customer’s behaviours and needs. It also allows new innovative use cases focusing on improving network and operational performances as, for example, Database consistency check or Roaming Analytics.

UDC cockpit (UPG): A powerful GUI tool to support the most common Operation & Maintenance activities providing information on the whole UDC system in a harmonized way. This functionality is provided by the UPG component, the same that provides the Analytics & Exposure capabilities.

The Ericsson UDC solution is very flexible and can be deployed in different ways according to our customer needs. It can scale from very small to very high capacity networks, offering different redundancy alternatives (e.g. 1+1 or 1+1+1) and each of its components can be deployed as a native stand-alone application, native co-located with other Ericsson applications or as a virtualized network function.

Proven leadership in Subscriber Data Management (SDM) market:
Ericsson is a recognized market leader in SDM solutions for data layered architecture by both market analysts and customers. With fully proven systems deployed in all the regions, Ericsson UDC has been contracted by more than 140 customers totalizing more than 4.7 billion subscription licenses shipped.

These systems include a variety of different front ends as, for example, HLR-FE, HSS-FE, EIR-FE, AAA-FE, ENUM-FE, MNP-FE and PCRF-FE.

Combined with the longtime leadership and experience from providing HLR and HSS solutions to mobile networks in the last decades, this has granted Ericsson a huge deployment experience including multi-vendor networks and swap-out scenarios.
