Service requirements for the User Data Convergence (UDC)
The present document describes the concept of the 3GPP User Data Convergence (UDC). It furthermore collects some architectural requirements and should be taken as guideline in stage 2 and 3 work.
The UDC will simplify the overall network topology and interfaces, avoid data duplication and inconsistency and simplify creation of new services by providing easy access to the user data.
Special consideration is put on the following areas:
- Categorization of the user data of services which would be converged in UDC
- Identification of the requirements on the common data model framework with focus on extensibility
- Identification of the requirements on the UDC for the support of new services including their provisioning
