1 cdma2000® Data Service Transition to NULL Support Jun Wang Ravi Patwardhan June 5, 2003 Recommendation - FYI Notice QUALCOMM Incorporated grants a free, irrevocable license to 3GPP2 and its Organization Partners to incorporate text or other copyrightable material contained in the contribution and any modifications thereof in the creation of 3GPP2 publications; to copyright and sell in Organizational Partner’s name any Organizational Partner’s standards publication even though it may include portions of the contribution; and at the Organization Partner’s sole discretion to permit others to reproduce in whole or in part such contributions or the resulting Organizational Partner’s standards publication. Qualcomm Incorporated is also willing to grant licenses under such contributor copyrights to third parties on reasonable, non-discriminatory terms and conditions for purpose of practicing an Organizational Partner’s standard which incorporates this contribution. This document has been prepared by Qualcomm Incorporated to assist the development of specifications by 3GPP2. It is proposed to the Committee as a basis for discussion and is not to be construed as a binding proposal on Qualcomm Incorporated. Qualcomm Incorporated specifically reserves the right to amend or modify the material contained herein and nothing herein shall be construed as conferring or offering licenses or rights with respect to any intellectual property of Qualcomm Incorporated other than provided in the copyright statement above.

2 NULL Transition MS or PDSN can release PPP state –Gracefully - Using PPP protocol –Ungracefully – Not able to communicate over PPP Ungraceful release of PPP –cdma2000® (air interface) signaling can be used to communicate state change »MS and PDSN are not out of sync Out of SYNC problems –If MS releases PPP, PDSN maintains PPP state unnecessarily –If network releases PPP, MS can not receive data from network

3 MS Initiated Transition to NULL cdma2000® (air interface) signaling support for NULL transition indication MS initiated Active to NULL transition supported –Release Order (ORDQ = ' ' i.e. Service Inactive Indication) –Resource Release Request Message (Purge_Service indicator) MS initiated Dormant to NULL transition not supported –Example: MS in relay mode »Laptop connected to MS has PPP protocol and MS is dormant »If laptop to MS cable is removed, MS transitions from Dormant to NULL. PPP can not send LCP Terminate Request. »Air interface can not indicate that dormant service is now inactive –Qualcomm’s contribution C /R2 proposes Service Inactivation Order from MS to BS

4 BS Initiated Transition to NULL cdma2000® (air interface) signaling does not support NULL transition indication BS initiated Active to NULL transition not supported –Example: when A10 connection for main SI is released »PDSN releases PPP –Changes required in air interface »Release Order (with new ORDQ to indicate Service Inactive) »ERM with PURGE flag BS initiated Dormant to NULL transition not supported –Example: PPP is released at PDSN (revocation, inactivity time-out or any other reason) when MS is Dormant –Changes required in air interface »Service Inactivation Order from BS to MS (similar to contribution C /R2 )

5 Recommendation In TSG-X PSN - discuss and approve cdma2000® (air interface) signaling support required for NULL transition indication Send correspondence to TSG-C indicating decisions –CC TSG-A on the correspondence, since TSG-A may have impacts
