User Data Convergence (UDC) enables converged subscriber data access. It ensures the consistency of storage and data models as follows:
Simplifies the overall network topology and interfaces by aggregating messaging to and from the UDR (Ud) and the OCS (Sy).
Overcomes the data capacity bottleneck of a single entry point.
Avoids data duplication and inconsistency across PCRF clusters within the same data center.
UDC simplifies the creation of new services and facilitates service development and deployment through a common set of user data. It promotes service and network convergence to support the increasing number of new services including Internet services and UE applications.
A new cache is provided in the UDC Frontend where the user data from the UDR is stored allowing for access from core and service network entities.
