3. 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

8. Blending of worlds
Time and time again the word
that is used to define the Ease of use
success of SMS is: ubiquity
Fast to deploy

12. 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

13. 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

14. 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
Acme Packet | www.acmepacket.com 14

15. 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

16. 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
