Project Description / Abstract
Software Architecture
for Data Storage Concepts within
Future Mobile Telecommunication Systems
In current mobile telecommunication networks, databases and the subscriber
data is distributed among multiple network domains and database systems. The
heterogeneous data storage concept is based on the permanent evolution of the
mobile networks and the support of different kinds of network technologies. Dependent
on the particular network domain and the dedicated technology, distributed
subscriber data has to be accessed via specialised protocols.
The research work proposes a novel software architecture for the next generation profile
register (NGPR) - an approach to provide subscriber information using a logically
centralised register for subscriber data from several mobile network domains.
The NGPR subscriber data model supports a network-independent layer that
references to different kinds of network-specific data (such as subscribed services,
user-related data and run-time data). Appropriate adapters ensure the reusage of
network-independent data for several specific mobile core domains or administrative
systems. This work includes an UMTS interoperability concept for the SS7
(signalling system no. 7) and IP-based domains by utilising the service-oriented
architecture (SOA). SOA concepts provide the flexibility to integrate different
network-specific domains by data services. The data services (based on web services
technology) are supported in a conventional way and by a binary mode
in order to improve performance for the telecommunication networks. The service
framework of the NGPR manages data services in general and links requests
from the mobile domains to relevant subsets of subscriber data. NGPR data services
support network-specific and generic interfaces that are proposed within
concepts of the next generation networks or UMTS release 6.
Based on SOA, the NGPR architecture provides subscriber data convergence
and simplified data access. Therefore, several specialised and generic network
domains can be directly supported by the network-independent layer of the NGPR.
Especially administrative systems and network nodes of closed domains are supposed
to take advantage of the interoperability concept and the converged data
of the NGPR.
