SpecialisedNetwork Elements

Specialized Protocols

Subscriber Data enclosed in

Network Elements

• a closed environment• a network for each

service• too complex• too expensive


The KILLER application in mobile networks

> The killer application for the next 5 years:

HUNDRED NICHE APPLICATIONS

> There is plenty of room for niche applications (supposed they are easy to use):• 1 single niche application may not show up in your

balance but,• 50 niche applications may boost your business.

• easy to extend• easy to integrate• easy to maintain


Use a service architecture for new applications

• standard interface towards external applications

Current mobile networks are very complexCurrent mobile networks are very complex

This complexity increases with each new applicationThis complexity increases with each new application

“HUNDRED NICHE APPLICATIONS!”“HUNDRED NICHE APPLICATIONS!”

Integration and maintenance costs increasesIntegration and maintenance costs increases


Conclusions 2

To reverse this evolution, out-of-the-box thinking is required

A switch from a functional centered architecture to a data centered one: the

storage plane

Current infrastructure (i.e. SAN) and software tools (Object Oriented

approach, CORBA, Database servers) supports the consolidation of data

Consolidate the interfaces : decrease work-flows complexity and integration

effort
