Document Purpose and Scope
• Generate a minimum set of common requirements for Wireless IP to be used by Operators and Device Manufacturers
• Separate access-agnostic IP requirements from access-specific requirements
• Wireless IP requirements focus on a base-level best effort data service
• Embedded and tethered devices

Document Development Process
• DSC team identifies priority – Done • GHRC team approves priority – Done • Document team lead and members solicited – Done • Document Introduction in face to face meeting – Today• Document development team activities (see next slide)• Final review in subsequent face to face Meeting• Document approval by GHRC• CDG SteerCom 30 Day Review, Release and Posting

Document Development Team Activities
• Generate document outline• Gather requirements & contributions from carriers • Compile requirements into document• Identify common, unique, or otherwise necessary
requirements for base-level wireless IP service• Create a generic requirements document• Work issues on unique technical requirements with
respective operators to arrive at generic requirements• Present and review the generic requirements document
during regular team conference calls or meetings
www.cdg.org7
Categories of Requirements
• Mandatory– Handset must support
• Highly Desirable– Recommended and may become Mandatory
eventually• Optional
– Handset may support• Discard
– Handset should not support
www.cdg.org8
Simple and Mobile IP
• Reference models– IS-835-D for SIPv4 and MIPv4– IETF RFCs for MIPv6 if supported
• Data service– MIP registration, re-registration after voice call,
deregistration, retry on failure– Address management w.r.t. DNS, DHCP, Home or
Foreign Agent• Configurability
– SIP configurations, fallback, PRI parameters modification
www.cdg.org9
Mobility Management
• Hand-off, hand-up, hand-down, failure• Handoff for active and dormant states• Data session continuity• Voice and SMS preemption behavior• Lost packet management for handoff• Location notification for handoff• MIP registration for PPP session re-sync
www.cdg.org10
Quality of Service
• As a base-level best effort data service, there is not much to specify
• Serves as a placeholder for future revisions of document with QoS
www.cdg.org11
PPP Configuration
• Session connect procedures• Session disconnect procedures• Tethered and embedded procedures• Dormancy support
www.cdg.org12
Security
• Authentication based on PPP procedures• NAI format and usage (if different than CDG-148)• Crypto keys – nothing proposed yet• TCP / UDP traffic handling for unsolicited datagram and
hot-lining (block all traffic to and from device)
www.cdg.org13
Accounting and Profiles
• Accounting – nothing proposed yet• Data profiles – Gold / Silver / Bronze• Payment method – unlimited, usage-based, etc• Roaming• Pre-paid packet data service
www.cdg.org14
Radio Channel Access
• Establishes the link to CDG-148, 1xEV-DOrA
www.cdg.org15
Test Mode
• Engineering test mode with restricted access
www.cdg.org16
Open Issues
• Is IPv6 support mandatory?• Simultaneous IPv4 and IPv6?• Multiple IP address support?
www.cdg.org17
Call for Volunteers
• Please help by taking ownership of a topic or contributing specific or general comments
• Subject matter areas where volunteers are needed:– PPP configuration– Crypto keys– Accounting and data profiles– Test mode
• Inputs need not be neat or organized
