4CAMS – CDMA Advanced Multimedia Services What Is CAMS? A framework for effectively delivering usable cdma2000 standards A systemwide view of the cdma2000 air interface and network that will allow operators and manufacturers to take better advantage of the technology than they can today A unique identity for the evolved cdma2000 system An effort to make better use of the resources available within 3GPP2

8CAMS – CDMA Advanced Multimedia Services Why Is CAMS Needed? Inter-TSG coordination is lacking in 3GPP2 – mainly because there is no “master plan” –The late development/definition of 1XEV-DO network support is a good example of the current poor coordination/planning –Rescue Channel was last-minute addition to Release B air interface that will have unknown impact on TSG-A (also not in 3GPP2 Work Plan!) Lack of synchronization between 3GPP2 air interface and network standards makes building systems extremely challenging No current work effort (including All-IP) exists to tie all the pieces of 3GPP2 together in a coherent and easily identifiable manner “I don’t have time to sharpen the axe – I’m too busy cutting down the trees”

10CAMS – CDMA Advanced Multimedia Services What Are The Benefits Of CAMS? End-to-end service-level view of cdma2000 network will facilitate coordination within 3GPP2 –Reduce/eliminate “orphan” capabilities that are supported in one part of the network (e.g., air interface) and not in another (e.g., RAN) –Avoid developing technology for technology’s sake Tying air interface capabilities directly to network requirements should streamline the process of defining 1XEV-DV –Services need to be understood and defined in order to provide suitable air interface bearers –Provides basis for making design decisions that is often lacking now

12
12CAMS – CDMA Advanced Multimedia Services How Should CAMS Be Implemented? Create CAMS Program Management Function within TSG-S –TSG-S has struggled to provide Systems and Services direction described in its Terms of Reference –Single, focused CAMS program will provide the vision and allow for giving clear direction to the TSGs –Minimal overhead required: CAMS content decisions can be made within an Ad Hoc Group of TSG-S Focus on 1XEV-DV air interface initially –Minimum support for All-IP, QoS and Header Compression required before a 1XEV-DV release can be considered fully functional –Allows for proof of CAMS concept

15CAMS – CDMA Advanced Multimedia Services Classification of Capabilities in CAMS TSG-A TSG-CTSG-NTSG-P TSGs will continue to have a mix of work, not all directly related to CAMS (i.e., standalone capabilities not managed by CAMS PMF) CAMS PMF would need to track all work activity in order to prepare realistic plan and schedule for CAMS releases 1 = Requires inter-TSG coordination -OR- high level of support 2 = Included in CAMS release -AND- lower level of support 3 = Standalone capabilities
16
16CAMS – CDMA Advanced Multimedia Services CAMS Will Address Existing Deficiencies Moves away from “wish list” type of planning to focus on core system objectives Goes beyond simple inter-TSG coordination by supplying unifying vision Ties together all parts of 3GPP2 –TSGs are largely autonomous today –All-IP AHG is currently air interface neutral/independent
17
17CAMS – CDMA Advanced Multimedia Services What is Danger of Doing Nothing? Lack of coordination and planning threatens the industry’s ability to deliver products based on 3GPP2 specifications Confusion and delay are likely if 1XEV-DV, QoS and All-IP continue to be developed independently –TSGs need common understanding of system in order to align their designs
