5 G T E C H N I C A L D ATA S H E E TWHAT’S COMING AND HOW TO GE T PREPPED NOW WITH THE NECESSARY TECHNOLOGIES AND S TANDARDS TO CAP TURE FIRS T-MOVER ADVANTAGE
5G—THE RUNDOWN
Network providers worldwide have begun testing 5G
networks, with widespread deployment expected by
2020. 5G is projected to deliver speeds up to 1000
times faster than 4G, have 99.99 percent availability,
and far lower latency. Unlocking the full potential of
IoT and with it, the ability to support billions (yes,
billions!) of devices simultaneously connected to
the network. Plus, provision countless known (think
autonomous cars and AR) and yet to be realized
industries and technologies that will deliver upward of
22 million new 5G related jobs by 2035, according to
MIT Technology Review.
MONE TIZING 5G—WHAT ARE THE TOP USE CASES?
As 5G becomes a commercial reality, and with advanced
trials underway, compelling use cases are starting to
emerge that will lay the foundations of a 5G future.
Fixed Wireless Access—The f irst widespread
commercially deployed 5G use case,
f ixed wireless access provides internet
connectivity to a home or enterprise using
wireless connectivity instead of f ixed/cable
infrastructure. Offering consumers and
businesses decisively faster and more reliable
mobile broadband.
Ultra-Reliable Low-Latency Communications (e.g. industrial
automation, monitoring and control)
Massive IoT (e.g. smart energy, connected vehicles, smart infrastructure)

Enhanced Mobile Broadband—Full mobile
5G may be a few years away, but shortly it
will deliver significantly faster, more uniform
data rates at much lower latency than its
predecessors…and better performance.
Making it feasible to access and consume
services such as HD/4K video streaming and
virtual/augmented reality on mobile devices.
Massive IoT—Sometimes referred to as Massive
Machine-Type Communications, enabling
seamless connectivity for the predicted tens of
billions (20.4 billion, according to Gartner) of
IoT devices and sensors that will be in service
by 2020. Massive IoT will support connectivity
for a broad spectrum of applications from
transportation to smart energy and city
infrastructure to name but a few.
Ultra-Reliable Low-Latency Communications—
The remote monitoring and control of
critical infrastructure (e.g. smart grid), self-
driving vehicles and industrial robotics,
will revolutionize much of how business is
conducted today, and particularly in rural areas.
SO WHAT DOES IT ALL ME AN?
With all these new 5G use cases comes infinite
opportunities, but for the most part, how operators
charge for 5G services will be fairly “business
as usual.” However, 5G networks and charging
systems will not. Requiring fundamentally different
technologies from their predecessors that are a
“must-have” to play and capitalize on 5G.
Virtualization—5G networks and associated
mediation and charging systems will be
expected to run in virtualized environments
(e.g. NFV—Network Function Virtualization) as
the default option in many cases.
Network Slicing—Unlike 4G, 5G will enable
network operators to provide portions of
their networks for different customer use
cases through network slicing. Each use case
receives a unique set of optimized resources
and network topology, allowing the creation
of multiple virtual networks on top of a shared
physical infrastructure. Advanced mediation
and charging systems must be able to run in a
distributed fashion in each virtual slice, and as
centralized instances communicating across
multiple network slices.
New Network Interfaces—Interfaces between
the 5G network and mediation and charging
will be based on HTTP2/JSON, whereas in
3G/4G these interfaces were Diameter based.
Meaning existing mediation and charging
systems will not be able to communicate with
5G network devices without having to be
either upgraded or customized.
Massive Volumes—Due to the increase in
both network traffic and devices connected
to the 5G network, there will be an enormous
increase in the volume of mediation and
charging events.
To effectively monetize 5G networks, off line and
online charging systems will have to align with
these technologies. Luckily, CSG customers are
covered. CSG already has in place the capabilities to
support network slicing, HTTP2/JSON and solutions
that can scale, mediate, charge and bill in any 5G
environment. CSG products have proven production
experience running in virtualized environments—
including VMware on customer premises, managed
service in CSG’s private cloud, and in the AWS public
cloud. On top of it all, CSG offers the only vendor-
supplied product to be certif ied as “Ready for NFV”
by VMware.

CSG GE TS ORGANIZ ATIONS PREPARED RIGHT NOW TO CAPITALIZE (AND MONE TIZE!) 5G
At a minimum, 5G will require a new or upgraded
Charging Function (CHF) capability, as the interface
to the network components, which was previously
Diameter, is now based on JSON/HTTP2. In cases
where the existing Online Charging System (OCS) is
being preserved and reused for 5G, CSG’s CHF solution
provides a fast time-to-market for 5G services by front-
ending the existing OCS and handling the new JSON/
HTTP2 interfaces to the 5G network components and
the Charging Gateway Function (as shown in Figure 1).
This approach preserves the existing online charging
system and shields it from the complexity of the new
5G network interfaces using the adjunct CHF solution,
ensuring minimal disruption and investment required in
order to charge for 5G services.
CSG also provides a fully integrated 5G Convergent
Charging System (CCS) solution that fulfills all 5G
mediation and charging requirements including OCS
(rating and balance management) as shown in Figure 2.
IN A NUTSHELL
Operators need a way to quickly scale their rating
and balance management system to handle the new
technology, capabilities and volumes 5G will deliver,
as today’s monolithic charging architecture can’t
keep up.
CSG’s 5G mediation and charging solutions help
operators quickly realize the value of 5G, and in a
deployment model that works best for them. CSG’s
proven scalability easily manages the billions of
events per day at ultra-low latency, even in virtualized
environments, with the option of preserving the
existing OCS system, or upgrading OCS to CSG’s
market-leading solution. With CSG, operators can
have their 5G and quickly monetize to boot!
