6. 6 Strategic Direction TR45.5 will: –Maintain and enhance the core specifications (cdma2000 1x, HRPD, and UMB) –Develop new technologies and services –Partner with 3GPP2 and its Organizational Partners and Marketing Representation Partners –Collaborate with other standards groups, e.g., 3GPP and WiMAX Forum on interworking –Work with ITU Provide ITU with updates of cdma2000 as IMT-2000 and Broadband Wireless Access (BWA) Provide ITU with input on the IMT-Advanced –Concentrate on environmentally friendly systems and services: Green Initiatives

7. 7 Challenges Increase capacity while maintaining service quality and system coverage to satisfy the market demands Enhance data throughput and reduce latency to accommodate the existing and emerging data services Continue to meet the time to market requirements by the industry

8. 8 Next Steps/Actions Continue to develop new technologies and services for the cdma2000 industry Innovate and improve existing systems in TR45.5 Work closely with regulatory bodies to provide solutions for location services, emergency notification, new frequency plans, and other governmental services

9. 9 Supplemental Slides

10. 10 IMT-Advanced Developed comments on the IMT-Advanced requirement (IMT.TECH) document Developed comments on the IMT-Advanced Evaluation Methodology (IMT.EVAL) Currently evaluating, assessing and consolidating technology proposals Develop Radio Interface Technology submittal for IMT-Advanced

11. 11 Emergency Services Commercial Mobile Alert System: –TR-45.5 and ATIS have been jointly developing the CMAS-related specifications common for the two groups –TR-45.5 has been working on cdma2000- specific CMAS-related specifications –Drafts of these specification are stable and TR-45.5 is on track to complete the publication in October 2008.

12. 12 E911 and Priority Services Support of granting priority access to cdma2000 services to a government related special class of users. Support identification of emergency calls originated by the mobile station. This indication is passed to the network.

13. 13 Location Protocols and procedures to enable mobile station assisted advanced forward link trilateration (AFLT) for HRPD access networks including Highly Detectable Pilot and UMB access networks Protocols and procedures to enable mobile station based AFLT for 1x, HRPD, and UMB networks Protocols and procedures to enable additional Global Navigation Satellite Systems, e.g., Galileo

14. 14 Band Class Enhancements Addition of band class support for the air- to-ground (airborne terminal and ground base stations) system operations Revised the 700 MHz band plan in response to band modifications defined by the FCC UMB system support in the band class specifications
