Standards for Voice over LTE GSMA Standards for RCS
(www.gsma.com/rcs/specifications)
Release 1
Offered the first definitions for the enrichment of voice and chat with
content sharing, driven from an RCS enhanced address book.
Release 2
Added broadband access to RCS features: enhancing the
messaging and enabling sharing of files.
Release 3
Focused on the broadband device as a primary device.
Release 4
Included support for LTE.
Release 5
The most recent release, global interoperability is a key aspect of
these specifications
RCS/joyn Services
• 1-to-1 Chat
• Group Chat
• File Transfer
• Content Sharing
• Social Presence Information
• IP Voice call
• Best Effort Video call
• Geolocation Exchange
• Network based blacklist
• Capability Exchange based on Presence or SIP OPTIONS

LTE Encourages Data Usage – Some Evidence
3G 8x 9x
2 – 2.5GB per month – 40% of New Adds
were 4G – 70% taking Unlimited Plan ($55)
3G 50% inc 1.6GB per
month
11-12GB per month – mostly dongle use
(similar to fixed network) Germany
Samsung figures show much higher use of LTE (141% inc over 3G – 3GB)

Five Considerations for Small Cell Rollout
Identifying Experience
Hotspots
How do I locate traffic Hotspots?
How do I target high value users?
Monetising Premium Wi-Fi
How do I create service differentiation?
What are new revenue opportunities?
Automated Backhaul
Design
What is the most effective design?
Which is the least cost/time option?
Catalogue Driven Rollout
How do I simplify network rollout?
How can I de-skill routine activities?
Network Policy Control
How do I ensure optimum application
experience?
How do I monetise premium services?

LTE Launch Strategies – Don’t Do This…
Charge a high and unjustifiable premium for 4G.
Fail to effectively communicate the benefits of 4G over 3G.
Offer a limited device line-up.
Fail to provision the network with devices to offer a
genuine 4G experience.
Fail to align marketing with network rollout.
Fail to clearly identify which segments of the market 4G is
targeting
Have a weak 2G/ 3G-to-4G migration strategy for existing
users.
18
LTE Launch Strategies – Do This…
Don’t charge a significant premium for LTE: Operators that
have successfully charged a premium for LTE have done so by making the
premium small and clearly justifiable, and at a level the target market will
accept.
Build out a network with good coverage in key cities/ areas
first, then expand to other major cities/ urban areas then out to rural areas.
Offer a compelling device portfolio at different price
points.
Communicate the value of LTE – emphasizing speed in
conjunction with enhanced quality has proved to be enough.
Use LTE to evolve the brand through emphasizing the
enhanced experience LTE offers.
Increase the overall value in the LTE subscription: premium
content, enhanced voice and messaging services have been proved to
improve KPIs.
