Blending of worlds
Time and time again the word that is used to define the
success of SMS is: ubiquity

Key pieces to the RCS service delivery puzzle
Service Reach
SIP normalization
Firewall traversal
iOS support
Lawful intercept
IM, VOIP
Encrypted traffic
Signaling & media
QoE
Battery life friendly
QoS marking
Security
DoS & overload protection
Encryption
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
Acme Packet | www.acmepacket.com
Signaling control for RCS: protecting service availability
13
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
Preserving ubiquity and user experience
14
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
Acme Packet | www.acmepacket.com
Lawful Intercept requirements
15
Lower TCO: interconnect for all
services
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
services
Dynamic, flexible routing lowers costs
