This study analyzes the progression of information models using some specific application
examples, in particular the applications of HSS-IMS and MMTel. It provides guidelines and preliminary requirements for the BSS provisioning capabilities and information model handling when new applications and related services are implemented in the operator's UDR by doing the following:
Develop several example initial SpIMs for discussion purposes.
Examine what BSS interactions with the Provisioning Gateway would be required to support provisioning of
user service and subscription data in the UDR for these SpIMs.
Study the relationship to the information model of TS 32.172 Subscription Management (SuM) Network
Resource Model (NRM) IRP Information Service.
Develop understanding of CBIM-derived entities of Application Information Models (AIM) for HSS-IMS and
MMTel from application data elements available in TS 29.364 IMS Application Server service data
descriptions for AS interoperability, TS 23.008 Organization of subscriber data, and other
Discuss the integration and consolidation of these AIM entities with the example initial SpIMs above.
Evaluate the potential changes to the BSS provisioning interactions for the implementation of HSS-IMS and
MMTel applications in the UDR and implications concerning the information model of TS 32.172
Subscription Management (SuM) Network Resource Model (NRM) IRP Information Service.
