  12. 12. IMS simplified Services enabled  Voice, video and RCSe  4G data services  FMC (small cell, WiFi)  Interconnect and roaming SMX Session management  CSCF functions plus SBC SBC and MSG Border control  P/E/I-CSCF + SBC  Multiservice Security Gateway Next-gen signaling core  Core Diameter Signaling Controller (DRA)  Session Routing Proxy (BGCF) Interconnect and roaming  I-SBC (I-BCF/I-CSCF)  I-DSC (DEA)

  18. 18. OTT style roaming& off-load solutions IMS/NGN SIP services Small WiFi WiFi WiFi cell IPsec TLS/DTLS RTMP (Flash) tunnels tunnels WebRTC
  19. 19. Tunneled Session Management (TSM) Service provider data center Exploits “app” rage Web SIP MSRP Tunneled session User DB  Single user’s real-time and data communication services within single tunnel - SSL/TLS, DTLS, others TLS or DTLS tunnel Management - Security - User authentication - Privacy and confidentiality - Service delivery security (Net-SAFE) - High availability - Admission controls - Bandwidth – per app, user group Acme Packet-enabled - Server transaction loads TSM client - Strict firewall traversal
  20. 20. TSM benefits Seamless roaming  Mobile device-optimized  Session ID & IP address held  Customized UI with constant by SBC and endpoint application-specific content  Tolerant of access network  Minimal impact on battery change & slow switchover consumption times  Simple integrated application  Endpoint appears static to download service delivery infrastructure  Standards-based IMS-VoLTE Tunneled Session Management - Acme Packet Confidential 20
  21. 21. TSM vs. RTMP/WebRTC TSM & SIP clients Browser-enabled RTMP or WebRTC Web SIP MSRP Web SIP MSRPIMS/RCSe servers core servers IMS/RCSe servers core serversdata center data centerAny Anynetwork network HTTP(s) SIP w/RTP MSRP HTTP(s) RTMP MSRP(s) /WebRTC Data Voice Video/file Data Voice Video/file video, IM share video share Acme Packet 21
  22. 22. 10M subs170-340K tps
  23. 23. Cost effective scaling solutions requiredto deal with growing signaling demands All-IP networks are LTE & IMS built differently 2G/3G & PSTN SIP VoIP  SIP to establish RCS VoLTE communication sessions SS7 Hosted UC  Diameter to exchange Diameter Authentication subscriber profile data QoS Charging Mobility Exploding signaling traffic  Moving beyond voice - UC, RCS messaging, collaboration  Extreme mobile data  Mobile device proliferation – smartphones, tablets, M2M  Increased mobility and roaming
  24. 24. Next gen signaling core requires scalable performance Diameter SIP core servers I/S-CSCF HSS, OCS, PCRF Roaming partners IP Peering I-SBC partners IPX carriers IP DSC TDM Wholesale transitRoaming hubs MGCF IPX carriers Diameter IMS NGN clients edge edge MME, PDN GW, SBC, C5 SS, GGSN, CSCF, AS P-CSCF S-MSC Internet LTE 3G DSL/Cable/ FTTx
  25. 25. VoLTE – making it work1. IMS – Is Makin’it Simple2. Roaming – interconnect & OTT flexibility3. Signaling core - scaling performance
