Qtel IPv6 Mobile Broadband Background 3 Presentation Title, Date Mobile Broadband IPv6 Service, MENOG 7
Qtel’s IPv6 Strategy & Priorities 1. Provide IPv6 capability for consumer access services 2. Prioritize services with largest public address space requirement 3. Maintain IPv4 for infrastructure and O&M whenever feasible 4 Mobile Broadband IPv6 Service, MENOG 7
Qtel Internet Service Trends 5 Mobile Broadband IPv6 Service, MENOG 7
The Case for Prioritizing IPv6 on Mobile Broadband 1. Largest and fastest growing number of subscribers 2. Least number of CPE issues a) Broadband Forum IPv6 support still at Working Text stage b) Supposedly wide IPv6 support in User Equipment (UE) c) HSPA modems generally don’t require IP addresses 3. Least disruption to existing infrastructure 6 Mobile Broadband IPv6 Service, MENOG 7

Mobile Service Considerations 3GPP Release versions 3GPP Release 7 (current) does not support dual stack 3GPP Release 8 (LTE) supports dual stack UE IPv6 Support WiFi generally supported 3G less clear Performance of IPv6 APN vs. IPv4 APN Throughput, latency, etc. Mobile device power consumption Access Point Name (APN) Requirements An APN address pool is either IPv4 or IPv6 (i.e. new APN required) Seamless transition to IPv6 considering diversity of UEs 8 Mobile Broadband IPv6 Service, MENOG 7

Lessons Learnt 13 Mobile Presentation Title, Date Broadband IPv6 Service, MENOG 7
Lab Testing More difficult than establishing an equivalent IPv4 Lab Unfamiliarity of IPv6 amongst stakeholders Issues with relatively new software features Shortened service development timeframe No risk to live service thus simpler change approval process Sandbox for engineers to learn from mistakes There is a financial cost Mobile Packet Core test lab infrastructure IPv6 feature licensing costs 14 Mobile Broadband IPv6 Service, MENOG 7
Going Live Introducing & supporting the additional IPv6 APN is complex subscriber configuration management (may initially be manual) Service configurations (Portals, MMS, etc.) Support systems & billing Handset support Identifying IPv6 capable UEs Procedures for configuring new APN on UEs Identifying and communicating with IPv6 candidate subscribers Measuring success of Mobile Broadband IPv6 service Classifying source of issues (UE, Packet Core, ISP, etc.) Measure churn between IPv6 and IPv4 APNs 15 Mobile Broadband IPv6 Service, MENOG 7
Highlights Project finished in approximately 8 months Extra time required due to summer vacations & Ramadan Relatively modest network infrastructure cost GGSN/SGSN licenses Professional Services No disruption to live IPv4 Mobile Broadband service Dedicated APN GTP Tunneling Major challenge is commercially supporting live IPv6 service Internal training Subscriber configuration issues UE support issues 16 Mobile Broadband IPv6 Service, MENOG 7
Potential Next Steps 17 Mobile Presentation Title, Date Broadband IPv6 Service, MENOG 7
Academic Engagement Engage Qatar-based Universities and Colleges as they can be good resources for; – Self-sufficient “tech savvy” users providing constructive feedback – Innovative adoption & development of IPv6 infrastructure – Helping support the transition to IPv6 within Qatar’s IT community 18 Mobile Broadband IPv6 Service, MENOG 7
Community Engagement Establishment of a local IPv6 Forum; – Tangible demonstration to the community that preparations are well underway for IPv4 address space exhaustion – Stimulate training and education in the ICT industry – Encourage development of IPv6 .qa content and resources 19 Mobile Broadband IPv6 Service, MENOG 7
Transition Technology Trial Identify transition technologies best suited to the Qatar market; – Migration of access infrastructure to IPv6 – Manage the complexity of crossing IPv4/IPv6 domains inside the service provider infrastructure – Seek incentives for users to migrate to IPv6 – Automatic steering of IPv6 capable UEs to IPv6 APN 20 Mobile Broadband IPv6 Service, MENOG 7
