Overview

• Quick overview of approved 3GPP2 femtocell management architecture

• 3GPP2 MO standardization process and liaison relationship with BBF

• Proposal for MO report format and TSG inputs• Proposed workplan• Proposed process for working with BBF• Recommendations

Background

• 3GPP2 began work on femtocell-related standardization in early 2007

• Technical activities were initiated in all 3GPP2 TSGs in late 2007– System requirements– Security aspects– Air interface (radio) enhancements– Support for legacy 1x circuit services– Packet data services for 1x and HRPD (EV-DO)

• Throughout 2008, extensive work has been done in all areas

• Publication expected in Q3-Q4 2009

Role of The TR-069 Standard inFemtocell Management (1)

• Broadband Forum TR-069 universally selected as the framework for femtocell management– Selected by 3GPP & 3GPP2 for femtocell management– Endorsed by Femto Forum

• Management architecture and TR-069 ACS are the backbone of the key femtocell operational and provisioning call flows in 3GPP and 3GPP2– Discovery– Registration– Redirection to alternate SeGW, ACS, or Femto Gateway– Self-organizing network/auto-configuration– Location verification– Provisioning and radio parameter assignments are managed

only by ACS– AAA and back-office interfaces are required only on ACS

Scope of Work for 3GPP2 Femto MOs

• Management Object contents– Attributes– Range of values– Hierarchical structure that is appropriate for 3GPP2 AIs– 3GPP2 will document these in a new technical report X.R00xx– This will serve as input to BBF to drive the 3GPP2 AI extensions to

TR-196• Definition of procedures that are required for the proper

interworking between the FMS (TR-069 ACS) and the FAP(s)– Procedures for discovery, registration, location verification,

provisioning, etc.– Sequences/high level call flows for those procedures– Any additional semantic rules for MOs– 3GPP2 will document these in a new specification X.R00xx

Workplan, Process, and Recommendations

14 September 2009

13

Proposed Draft Workplan (1)

• Preliminary discussions with BBF indicates:– Tentative proposal to incorporate 3GPP2 AI MO

extensions into a new version of TR-196 makes sense

– Would like to receive inputs from 3GPP2 as early as possible

– Prefer to receive preliminary draft of MO contents early

– Final (extremely) stable version as a followup– Crude estimate is 6 months from final MO inputs to

publication

14 September 2009

14

Proposed Draft Workplan (2)

• Initial proposal for 3GPP2 workplan:– June – Call for MO inputs within 3GPP2– August – First draft of MO inputs– November – Harmonized draft of X.R00xx containing

MOs baselined– November – Transmit X.R00xx to BBF as first draft– January 2010 – X.R00xx enters first pass V&V– January 2010 – Transmit final version of X.R00xx to

BBF– March 2010 – X.R00xx enters TSG-X Re-V&V– ~March 2010 – BBF Straw Ballot– June 2010 – X.R00xx published– ~June 2010 – BBF Final Ballot completes

14 September 2009

15

Proposed Process for Working with BBF

• Complete establishment of liaison relationship (BBF and 3GPP2 Secretariat)– Correspondence 8 July 2009– BBF “Collaboration” relationship– IPR policies– Establish document sharing rules– Meeting sponsorship and working rules for joint calls and/or meetings

(e.g., who’s running the meeting under what rules and with which IPR policies)

– Negotiate rules for comments provided to/from 3GPP2 from/to BBF• Complete establishment of day-to-day working liaison relationship

– Periodic leadership calls between BBF and 3GPP2 to coordinate (esp. after exchanges start occurring)

– Procedures for submission of comments against BBF straw ballots, etc.– Re-use of text from each others’ specifications

14 September 2009

Recommendations

• Adopt proposed work process jointly (previous slide)• Agree on intent to follow proposed workplan (previous slide)• Agree that 3GPP2 femtocell MOs will be in a new version of

TR-196• Identify points of contact
