State of RCS – making progress

 Launched and live (or coming soon)

 RCS 5.1 specification is done

 Handset and app support grows

 Legacy messaging in decline

Key pieces to the RCS service
delivery puzzle
Service Reach Lawful
SIP normalization intercept
Firewall traversal IM, VOIP
iOS support Encrypted
traffic
Signaling & media

Security
DoS & overload
protection
QoE
Encryption
Battery life friendly
QoS marking


Signaling control for RCS:
protecting service availability
 Requirements
 Granular security per service & application
 User definable

 Key features
 Signaling rate limiting
 Access control lists and SIP Methods
whitelists/blacklists
 Topology hiding
 Signaling screening = Signaling DPI
 Encryption: extending RCS to WiFi/Internet


Preserving ubiquity and
user experience
 Battery life
 Issue: Presence or keep-alive messages
 Requirement: network sends lightweight
messages to traverse NAT devices

 Wide handset support
 Issue: iOS “multitasking” limitations
 Requirement: network sends TCP traffic to
keep apps awake

 VideoShare behind a NAT
 Issue: Unidirectional communication can be
blocked by NAT devices/firewall
 Requirement: network makes flow
bidirectional

 Simplify: bundle functions into access SBC


Lawful Intercept requirements

 Intercepts all communications
 Replicates media (call content)
 Replicates signaling (call data)
 SIP, MSRP, RTP
 Any SIP Method –
including REGISTER, MESSAGE

 Interoperability with range of IMS networks

 Encrypted sessions (SRTP, MSRPoTLS)

 Simplify: combine functions in access SBC

Now make it global:
SIP interconnect
 Lower TCO: interconnect for all
services
IPX MNO
 Mobile-mobile, mobile-fixed
 RCS, 2G/3G voice, VoLTE, video
 Bi-lateral & IPX interconnect

 Secure, managed interconnect border
 Security assures network availability
 Layer 3-5 mediation maximizes service
reach and accelerates time to market
 QoE controls provide high quality Fixed 3G/LTE 2G/3G
services
 Dynamic, flexible routing lowers costs


MetroPCS selects Acme Packet
for VoLTE and RCS service

Summary

 RCS services are integral parts of all-IP evolution

 Service provides to leverage its strengths
 Security
 Reliability
 Interoperability

 Simplicity, speed and scalability are key to
making RCS work

 Rich functionality required to meet RCS security,
interoperability and regulatory requirements

Making Joyn „real‟ in Vodafone
markets and beyond

20 C3 Vodafone Confidential | 28 November 2012

The Telco world is one founded on service
interconnect to achieve ubiquity…….

Telco Service Distribution Model OTT Service Distribution Model

However……
As we transition to all IP,
operators require new
infrastructure to complete
the map, and device
development & test load
becomes exponential with
each new service, and
each new service instance


Hosting is the key industry simplification needed to
evolves operator communications services, not apps,
over data
