International standards development activitiesThe comments on the activities under each topic are primarily based upon the presentations at the Global Standard Collaboration (GSC-10) meeting held in September 2005. It is intended over time to update this information to keep it current with overseas activities and relevant to issues being address by Communication Alliance advisory groups.
Next Generation NetworksThe ITU NGN Framework outlines high-level requirements and guiding principles – interconnection, QoS, interfaces, FMC, Public/private convergence, E2E communications. ITU NGN Release 1 targeted for November/December 2005. The next phase of NGN work is referred to as the NGN Global Standards Initiative (NGN-GSI). The FGNGN is to wind down but another group may follow. Discussion continues on the conceptual framework – whether IMS-based or to include other approaches (e.g. call servers). The ATIS NGN Framework Part 1 was published in 2004. Collaboration of ATIS NGN Focus Group & ETSI TISPAN ongoing . They share their Framework document with 3GPP, ETSI and ITU. Collaboration between ITU & IETF – differing approaches to QoS and security. In regards to IPv6, agreed to collaborate & not overlap. The ETSI - First Release of ETSI TISPAN specifications scheduled for end-2005. Based on 3GPP IMS R6 & R7 with extensions. (multimedia services – QoS, security, regulatory, ENUM etc. R2 to cover content delivery. R3 to cover mobility. ETSI TISPAN contributing to ITU-T on a global standard. IETF is looking at TISPAN NGN doc as a RFC & to include SIP extensions. ITU web based NGN project management tool – freely assessable. Need for a coordinated global study of SIP profiles. There is a shared desire to move towards a SINGLE SIP profile solution. Active organisations/groups: ATIS, ITU, ETSI TISPAN, CCSA, TTA, TTC, IETF
DSLWork on VDSL2 is at resolving comments of ITU-T SG15, with a possibility of a publication with an American annex. Covers bandplans, power spectrum densities, total transmit power and dynamic rate partitioning.ADSL2plus – working on interoperability & impulse noise protection. SHDSL & G.shdsl.bis. now harmonised. Dynamic Spectrum Management (DSM): (anticipated ballot 1Q2006). Technology to enhance spectrum-management value by dynamic management of DSL spectral compatibility. Network End Line Sharing Splitter – CO splitter for VDSL2, CPE splitters for ADSL, VDSL1, VDSL2 DSL Bonding – combining pairs for higher rates. Active organisations/groups: ATIS, ITU, ETSI TISPAN, CCSA, TTA, TTC, IETF
VoIPEmphasis that the work should remain ITU-centric.Security and QoS are the two issues high on user interest list. Security Voice-over-IP (VoIP) telephone network security – vulnerability a major issue. TSB-139, IP Telephony Security Framework. In Japan, market well progressed. 8 million users, bundled with broadband – standards define usage (not new protocols), SIP is at the core. VoIP End-to-end QoS. Speech quality Standard JJ-201.01. G.1010, End-user multimedia QoS categories - audio, video, data, background application. Categories based on tolerance to errors and tolerance to delay. Y1540 : Network Performance parameters. Y 1541 : Network Performance Objectives. End-to-end communications -promoting ITU X.805, for any Network Technology. Work on user profiles. Active organisations/groups: ITU, ESTI STQ, IETF, TIA, TTA, TIA TR-41.4, ATIS PRQC, TTC
Broadband WirelessThe ITU provides the coordination of IMT-2000.Interoperability/interworking specifications in 3GPP and 3GPP2 between RLAN and IMT-2000 are being developed. New contending technologies like WiBro (portable internet) by Korea being noticed. Development in installations & cabling is ongoing. Broadband Wireless Access (BWA) is being carried out by ETSI BRAN, IEEE & WiMAX. Interoperable BWA systems (IEEE 802.16-2004 & HiperMAN and HiperAccess). ETSI & WiMAX agreement in place, recognising competences: ETSI – protocol test suites, air interface spec, regs. WiMAX – marketing & promotion, certification, network interface specifications. The broadband wireless IEEE 802.16e Standard is nearing release with the mobile version anticipated for end of 2006. The EU is developing harmonized EN covering essential requirements (like GSM and DECT in the past). Interest in Ultra wideband (UWB) is gaining momentum, providing high mobility and high bandwidth. Application is in the personal space alongside of WAN. Has many regulatory and technical considerations. Regional and rural broadband solutions such as hybrid architectures and FMC are being encouraged. Active organisations/groups: TTA, ITU-T SG6 & ITU-R, IEC & CELELEC, ETSI BRAN, ITU & IEEE 802, ETSI, IETF, ARIB, TIA, MESA, 3GPP & 3GPP2
Emergency callingMESA, European emergency call handling requirements (e.g., ETSI SR 002 180)TIA/TSB-146 (2003) Telecommunications – IP Telephony Infrastructures – IP Telephony Support for Emergency Calling Service. TIA developed J-STD-034 and J-STD-036 Developing requirements for E911 over wireless and VoIP networks Emergency communications - much focus, including the potential loss of PSTN service capabilities Active organisations/groups: TIA, ETSI/TIA, TIA TR-45.2 & ATIS WTSC
Location based servicesControl Plane Specifications - 3GPP (TS 21.271, TS 23.271, TS 43.059, TS 25.305, etc…)Proprietary Specifications - GPS 1 V1, V2 User Plane Specifications - TIA TR45/3GPP2 IP Based Location; OMA Secure User Plan Location Active organisations/groups: ATIS, 3GPP, GPS, TIA/3GGP2, OMA
Standards developmentNew Standards markets: China, 400 Standards, 1000 proposals to ITU, 3GPP, 3GPP2, CJK, TMF & others. The Eleventh Five-Year Planning for communication standards’ started CJK – (China/Japan/Korea) – regional standards collaboration ITU Workshops – audio webcast, slides (e.g. QoS workshop, Geneva, June 14-16, 2006) Increasing fora. Fragmentation of Standards development: 1983-1998 – 50 fora, by 2003 it doubled to 100. Operability is becoming the key standards issue. ETSI is focusing their strategic standardization towards middleware and applications. In addition to traditional committees, starting up ‘quick specification groups’. The standards environment is competitive for resources and knowledge. Fora such as the Open Mobile Alliance (OMA), specifically on interoperability, are filling niche markets. TTA noted the following growth drivers: Next Generation Mobile Communications, Digital TV, Home Network, IT SoC, Next Generation PC, Embedded S/W, Digital Contents Activity in telematics and Intelligent Robotics. |
