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

Categories of Requirements

• Mandatory
• Handset must support
• Highly Desirable
• Recommended and may become Mandatory eventually
• Optional
• Handset may support
• Discard
• Handset should not support

8
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

9
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

10
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

11
PPP Configuration

• Session connect procedures
• Session disconnect procedures
• Tethered and embedded procedures
• Dormancy support

12
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)

13
Accounting and Profiles

• Accounting nothing proposed yet
• Data profiles Gold / Silver / Bronze
• Payment method unlimited, usage-based, etc
• Roaming
• Pre-paid packet data service

14
Radio Channel Access

• Establishes the link to CDG-148, 1xEV-DOrA

15
Test Mode

• Engineering test mode with restricted access

16
Open Issues

• Is IPv6 support mandatory?
• Simultaneous IPv4 and IPv6?
• Multiple IP address support?

17
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
