Jeju, 13 – 16 May 2013Standards for Shared ICT Standardization activities on Broadband Wireless Access in CCSA Wang zhiqin CCSA Document No: GSC17-GRSC10-13 Source: CCSA Contact: Zhiqin Wang GSC Session: GRSC10 Agenda Item: 4.1

GSC17-GRSC10-13 GSC-17, Jeju / Korea Standards for Shared ICT BWA Technology BWA technology is focus on industry applications SCDMA, TD-LTE has been deployed in various industries including airport,railway,harbor, smart grid,oil&gas, multi government and mining. Service requirements for industry broadband applications Trunking services: same performance to TETRA Multimedia command and dispatching services: Voice, data, multimedia, trunking services integration Performance ： delay and reliability is more critical 2 Technology enhancement of BWA system

GSC17-GRSC10-13 GSC-17, Jeju / Korea Standards for Shared ICT Evolution of SCDMA system Narrowband SCDMA Narrowband SCDMA McWill （ Broadband SCDMA ） McWill ( Mutimedia trunking system) McWill ( Mutimedia trunking system) Service: fixed voice Frequency: 400MHz/1800MHz Mainly applied in rural areas  Service: data, voice  Frequency: 1800MHz  Supporting high speed data access  Service: data, voice, trunking service  Application: business users SCDMA is a wireless access technology developed by Beijing Xinwei Telecom Technology Incorporation. McWill was finally accepted as one BWA air interface of ITU-R M.1801 recommendation at ITU-R WP5A session.

GSC17-GRSC10-13 GSC-17, Jeju / Korea Standards for Shared ICT Standard of TD-LTE based Trunking Technology Phase1&2 standard plan –Phase 1: local network, trunking enhancement, IOT of terminals –Phase 2: large network scale, roaming, more service support 4 System architecture ( Phase 1) Standard projects under development –General Technical Specification for TD-LTE based Broadband Trunking System (Phase 1) –Technical Specification for TD-LTE based Broadband Trunking System (Phase 1) : Air Interface Interface between Trunking Core Network and Dispacher Interface between UE and Trunking Core Network

GSC17-GRSC10-13 GSC-17, Jeju / Korea Standards for Shared ICT Time plan of TD-LTE Based Trunking Technology Standards (phase 1) 5 General Technology Requirement Air Interface Interface between UE and trunking core network Interface between trunking core network and dispatcher Technical requirement of UE, BS, trunking core network and dispatcher Test methode
