• SCDMA (Synchronous CDMA) is the wireless access technology more
Focus on the local network deployment and Universal Service
• CCSA is pushing and in charge of the standardization of SCDMA
• Two versions of the SCDMA
– Narrow band SCDMA Radio Access System
• Voice and low data rate
• limited roaming within one city area
• 400MHz and 1800MHz for rural and city deployment respectively
– Wide band SCDMA Radio Access system
• VoIP and high data rate
• OFDM based system
• Focus on providing high efficient voice and data services to rural areas and private networks
• Standardization on Wide band SCDMA is ongoing in WG3/TC5/CCSA
• Standardization on Narrow band of SCDMA was finished
2

• Developing Standards on inter-working between wireless systems and cellular systems
• Demands with different scenarios should to be met by the combination of different technologies
– Broadband wireless access system provide high data rate, limited coverage and mobility services
– Cellular system (eg 2G/3G) provide QoS guaranteed voice and low date rate services with wide coverage and high mobility
• Activities on this topic in CCSA
– Study report on Inter-working between WLAN and 3GPP/3GPP2
– Study report on Inter-working between WiMAX and 3GPP
– Considering a new study item for Inter-working between WiMAX and
3GPP2 system.

• Standard research on short range wireless communication
– Standardization on Telecom-based short range wireless requirements
• Short Range Wireless technology is an important member of the wireless access family.
– Play a important role in wireless sensor network and ubiquitous network
– We pay more attention on Telecom value-added services based on
Short Range Wireless

• Developing standards of SCDMA to meet the requirements of
Universal Service
– Low cost BWA system for rural communication
• Wide coverage, convenient maintenance ,low cost
• Voice+data
• Two phases of the standardization of SCDMA
– Phase1: finish the development of the narrow band SCDMA (done)
– Phase2: finish the development of the broad band SCDMA (active)
• Begin with air interface protocol and system requirement
• Then specification of the equipments including base station, terminal and others
5

• Standardization research on the inter-working between BWA and cellular system
– Different broadband wireless access technologies work together ；
• Multiplicity coverage method （ hotspots, hot zone, nomadic and limited mobile)
• data-oriented
• Complement with mobile network
– Two phases of the standard research of the inter-working
• Loose coupling
– Common AAA ( Accounting, Authentication and Authorization )
• Close coupling
– Seamless handover between different systems
6

• SCDMA
– How to standardize the core network of SCDMA system need to be studied.
– Need the further study on the requirements of Universal Service and the impact on the standards
• Inter-working
– Several SDOs are related with this topic
• 3GPP, 3GPP2, IEEE, etc
– The work within each SDO shall be aligned with each other
• Communication and collaboration
• Telecom-based short range wireless
– Need further study on the application scenarios
7

• Complete the current active items
– Standards of Broad band SCDMA
– Study reports on inter-working between BWA and 3G systems
– Finish the standardization of the Telecom-based short range wireless
• Further communication and collaboration with other SDOs and forums
– 3GPP, 3GPP2, IEEE, WiMAX forum, Zigbee Alliance
– Other counties’ SDO
