13 What’s LTE/TD-LTE
LTE=Long Term Evolution TD-LTE=TDD mode of LTE
2G 3G 3.9G 4G TDMA CDMA OFDM LTE-A
GPRS/EDGE WCDMA HSPA •Peak Rate •Peak Rate：5.76/14.4Mbps LTE-FDD 0.47/0.47Mbps •Peak Rate TD-SCDMA TD-HSPA 35/75Mbps LTE-Advanced
3GPP(GSM) •Peak Rate：0.55/1.68Mbps
TD-LTE •Peak Rate cdma2000 1x EV-DO Rel. 0 D0 Rel. A •Peak Rate 500Mbps~1Gbps 28/84Mbps •Peak Rate 3GPP2(CDM 1.8/3.1Mbps A)
Mobile WiMAX 802.16m 802.16e WiMAX •Peak Rate •Peak Rate 33/75Mbps 500Mbps~1Gbps IPv6 in TDD-LTE should be promoted
Large amount of IP address is needed, IPv6 is essential for LTE
•IP address amount in LTE is about 20-40 times of that in 2G/3G •LTE is always-on, which means whenever the terminal turns on no matter whether a service will be used or not, IP addresses should be assigned to the terminal. •Multiple APNs is needed for LTE. Multiple IP addressed should be assigned to one LTE device
15 TD Terminals is not Ready for IPv6 Deployment
IPv6 is important for TD
GERAN HLR
Um •When a terminal is switching Gb Gr SGSN GGSN BTS BSC/PCU Gn UTRAN between LTE and 2G/3G network, Iu Uu Iub S3 S4 service continuity should be NodeB RNC E-UTRAN MME HSS PCRF S12 supported S6a S9 S1-MME S11 Gx
LTE-Uu •Some IPv6 service should be S5/8 S1-U
eNodeB supported by 3G network Serving GW PDN GW
16 How to improve terminal’s IPv6 capability
• Application – should be able to work both on IPv4 and IPv6 stack • OS – support IPv6 stack • Chip – In TD and TDD-LTE terminal
• Software should be upgraded to support IPv6 • chip is also needed to be changed to support IPv6 – In WLAN terminal • Chip Is not needed to change
17 Applications and Equipments are not Ready
Application and software Some Equipments
All self service platforms in China Mobile’s • Some important date equipment in IDC, network are IPv4-only now for example Fire Walls and Load balancers, are not support IPv6 Most Client are IPv4 • Test Result shows that IPv6 capability is •12 in 50 client software are IPv6 ready not supported well in some equipments. •Browsers work well on IPv6 OS For example, • 5 types of BRASF from 4 vendors are •IM, on line VIDEO in the test do not support IPv6: tested MSN, QQ, Fetion,PPLive, UUsee, PPstream, QQ • Basic IPv6 protocol functions, such as Live PPPoEv6 and routing, are supported Most WebSites are IPv4. According to the well statistics by Alex • DHCPv6 Server function is not 1.3% of top 25K websites are IPv6 ready supported in 4 types of BRAS from 3 vendors. 1% percent of top 1M websites support IPv6 • IPv6 FIB capacity is only 10% of IPv4 FIB Capacity 18 Agenda

IPv6 Working Plan
19 IPv6 target and plan in China Mobile
China Mobile will promote IPv6 in the E2E industrial chain and carry out large scale experiments and trials in the next few years
Start-up Period Promotion Period Application Period （2011-2013） （2014－2015） （2016－2020）
To 2013: To 2015: To 2020: Do IPv6 experiments complete network IPv6 All the increased and trials in related provinces, develop transition subscribers and about 3M subscribers Start IPv6 commercial service use IPv6 Produce more and deployment address more LTE/3G UE Develop more IPv6 All the backbone support IPv6 with the association of subscribers and MAN use IPv6 manufacturers
20 LTE Terminal Development
• By the end of 2013, 5K TDD-LTE terminal prototypes, with at lest 4 TDD-LTE new terminal chips will be used in IPv6 trial – TDD-LTE single-mode mobile phone and data card – 2G/TD/TDD-LTE multimode mobile phone, Multimode Data Card – TDD-LTE CPE
21 Network Trial (2012-2013) Plan
According to our government IPv6 plan: TDD-LTE Test and Trial in 4-10 cities WLAN Test and Trial in 6-10 Cities Wireline Access Test and Trial in 4-10 Cities Commercial Service • Around 10 China Mobile’s self service platforms, including mobile reading/mobile mailbox etc. About 3M commercial trial users by the end of 2013
2222 Conclusions
• The demand of IPv6 has become increasingly urgent • the ecosystem of IPv6 is still incomplete and needs more work to accelerate the process, especially in TD and TDD-LTE • China Mobile is willing to work with industry and standard bodies to promote IPv6 deployment – IPv6 will be trial and tested in a large scale in the next 2 years
