2. 2 Application of Revision Document for 1X Enhancement The following document strategy options for 1x Enhancement are available: We propose the “Stand Alone approach” Add the feature on each Revision(Rev.0-D) Like C.S0072 (Interim MEID Solution) “Stand Alone approach” has several advantages over “New Revision approach” 1.Less “Development Complexity” 2.Less “Evaluation Complexity” 3.Less Impact on “Deployment Schedule” Rev.0Rev.ARev.BRev.CRev.D 1X Enhancement Rev.E 1X Enhancement “New Revision approach” “Stand Alone approach” Rev.0 Rev.A Rev.B Rev.C Rev.D

3. 3 Advantages of “Stand Alone Approach” 1.Less “Development Complexity” Network upgrades can be supported for enhancements only and do not mandate inclusion of undesired features from Rev. A to Rev. E To upgrade new revision, only desired 1x Enhancement features are implemented, not all Rev. E features Most operators have 1X Rev.0 or Rev. A currently deployed in their networks New Revision approach need to re-develop PLCM_39 function C.S0072(Interim MEID Solution) is invalid on upper Rev. C re-develop PLCM_39(BS assigned PLCM) function for Rev. E MS 2.Less “Evaluation Complexity” Need to evaluate Enhanced MS Need to ensure no impact to Legacy MS operations Do not want reoccurrence of 1X Rev. A Sync channel issue in 2002 3.Less Impact on “Deployment Schedule” Desired for Early deployment 1x Enhancement needs the support of both network and mobile capacity effect depends on # of supported mobiles Unnecessary work should be eliminated for early deployment eliminate the work regarding dev/eval of undesired features Rev.0 Rev.A Rev.B Rev.C Rev.D Rev.E

4. 4 Conclusion Conclusion: “Stand Alone approach” is preferred over “New Revision approach” for development and documentation of 1x Enhancements –Eliminate unnecessary work –Minimize system complexity –Shorten development/evaluation schedule Operators desire 1x Enhancement to increase system capacity of their current network deployments Minimize development/evaluation
