1. New service architectures are changing the
requirements in protocol and business
logic, and they are also challenging exist-
ing data management solutions. Up until
now the main products focused on static
subscriber profiles generated by HLR and
HSS. Beginning today it is mandatory to in-
clude dynamic session data from packet
core elements, IMS and other services and
to scale their capacity to meet Internet of
Things dimensions.
The latest data frontends don’t just require ad-
ditional storage capacity, they are also
resulting in new requirements in terms of re-
sponse time and scaling. Specifically, resizing
under load, with no downtime is increasingly
important for operators who are addressing
new markets and use cases like IoT (Internet of
Things) and the OTT (over the top) world.
An enormous number of new entities includ-
ing subscribers, devices, and business rules
must be added to a running service.
So it’s time to start from scratch, taking all les-
sons learned into account.
Siemens Common Repository (SCR) is based
on a revolutionary architecture that imple-
ments all features of a large-scale subscriber
profile and session data management system
sufficient for the next 15 years.
Using a self-organizing and adapting architec-
ture, SCR provides almost unlimited scaling
data-storage with real-time access to all types
of dynamic and static data. With its multipro-
tocol access layer, it provides a single location
for data storage for all existing and future core
network applications, as well as a platform for
big data analytics.
The SCR has been specifically designed for
telco cloud deployment: It supports full elas-
ticity and employs the benefits of
virtualization and orchestration, allowing fast
response time, easy operation, and optimiza-
tion of operating costs.
SCR has what it takes to become the technol-
ogy leader of the next data management
revolution. Almost ten years after centralizing
all subscriber profiles, now is the time to do
the same for dynamic session data in order to
finally generate a single view of all relevant
core network data that your network needs.

2. A world of subscribers on the move
In today’s telco world operators must be able
to quickly react to change. And that means
faster than ever before! In competition with
the rapidly maturing IT world, the telco busi-
ness needs to be able to adapt to any new
requirement within seconds without losing the
reliability and stability customers expect. This
can only be ensured by adapting the existing
elements to the new requirements. The intro-
duction of a central subscriber and session
store – designed for cloud deployment – ena-
bles the frontends to become stateless, which
decreases the operational costs and complex-
ity. This in turn saves money as well as human
resources, all to the operator’s bene-
fit. Standard interfaces make the
change as simple as possible, while
the design of the central database
ensures maximum availability and se-
curity of the sensitive customer data.
Independence from the vendor’s pre-
ferred hardware solution is an
important factor for cost-conscious
operators. The virtualization of the
elements and services offered by
cloud solutions makes it possible to
separate the infrastructure from the
products themselves.
New solutions must be designed
with virtualization in mind, and oper-
ational as well as technical elements
need to be taken into account. Quick
adaptation to changing HW re-
sources and insensitivity to HW failures must
also be considered in the design phase, just
like the ability to scale in and out or up and
down depending on performance needs and
available resources with no service interrup-
tion.
IoT is bringing unexpected and heretofore un-
known requirements to the table. “Things” in
the IoT can refer to a variety of devices beyond
our imagination today. Networks may need to
serve smart devices in health care as well as
smart houses and cars. Operators will be re-
quired to respond to these requirements
extremely quickly and scale their systems to
the new needs within seconds.
