Introduction – Current Landscape
TDM carries majority of international voice traffic:Milk investments in TDM switchesRetail traffic is quality sensitiveService features deployed require use of SS7 to work correctly e.g.
voicemail OCN/RDN; release/cause code mapping is not consistent
But: VoIP used extensively in domestic and international wholesale:But: VoIP used extensively in domestic and international wholesale:Access to emerging markets using public Internet as transportInterconnection to resellers and wholesalersITSPs using VoIP to avoid conversion costs for interconnectionITSPs using VoIP to avoid conversion costs for interconnection
Introduction – VoIP Drivers
Transport cost reduction ‐ Carrier Ethernet/MPLSBetter capital utilization
Cost Savings

General structure for IP interconnection for not just mobile operatorsGeneral structure for IP interconnection for not just mobile operators but all SPs.
i3 and GSMA collaborating on voice over IPX (VoIPX), unified approach to ensure quality and feature interworkingto ensure quality and feature interworking
Further interworking provided for Data Roaming, SMS/MMS and new services
Opportunities/ChallengesOpportunities:HD Voice – quality well in excess of TDM using broadband codecsHD Video ConferencingH Video ConferencingNew services – presenceCost savings and quality improvements on current voice
Challenges:Routing & Addressing to support PeeringDirect routing requires incremental knowledge:
Number Portability in distant operator/countryService capabilities of end users – HD voice capable?
Integration of Peering and LCR approachesEconomics of many direct peers versus using trusted partnerSecurity and Fraud PreventionSecurity and Fraud PreventionTransport Network Issues & IPv6
Need to balance:
Direct peering routes
Peering via Intermediaries

IMS vaguely defined interconnect between IMS networks from the CSCF via a BCF & TrGW. ITU-NGN simply indicated the use of BCF but also state that PSTN Emulation Subsystem should use SIP-ITISPAN NGN indicate use I-BCF and BGF.

The new Interconnect Solutions have to:• Simplify the transition to VoIP with any-to-any voice and multimedia
interconnections IP to IP IP to TDM TDM to TDM; fixed mobile andinterconnections – IP to IP, IP to TDM, TDM to TDM; fixed, mobile, and satellite
• Create competitive advantage by reducing the number of network components and transaction costs, and enhancing QoS and voice handling
• Provide fast ROI, reduces time-to-market for new services • Create new opportunities for growth and expansion, such as interconnection
with GSMA’s IPX and other peering services All ff ti d i ti f TDM t• Allow effective cap-and-grow migration for TDM assets
• Reduce capital and operating cost structure for greater margin flexibility • Simplify operations and improves service visibility via a single vendor
