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
