Mission

• Ensure that carriers that want to roam, can roam
• Develop implementation guidelines to enable
  roaming for new services and capabilities which
  will result in additional revenue for carriers
• Work on projects which will
• Enhance roaming experience for subscribers
• Reduce operating cost of roaming service for
  carriers
• Reduce time-to-market for carriers to initiate
  roaming service

CDG Roaming Efforts

• International Roaming Team (IRT)
• Roaming Project New
• Launched in March 2005

Relationship Among CDG Roaming Efforts

• CDG Roaming Project vs. IRT
• Efforts are complementary
• IRT works on issues of interest to active
  participants
• Mostly advanced operators
• Examples are packet data roaming, direct routing
  roamer-to-roamer (DRRR)
• CDG-RP works on basic issues of training,
  tools, documentation, testing, carrier processes,
  industry metrics, etc.
• IRT will review and approve roaming project
  deliverables

IRT Status of Priorities
Note New prioritization underway now. Will be
finalized during June IRT meeting

• CDG Executive Board endorsed CRX
• Carriers are now signing agreements with CRX
  providers
• Syniverse
• Verisign
• Aicent

10
Upcoming IRT Meetings

• June 23 24 Boca Raton, Florida
• Co-locate with Syniverse Solutions event
• Hosted by Syniverse
• September 2005 India
• Dates are TBD
• December 2005 Location TBD
• Typically co-located with 3GPP2 in Hawaii

11
CDG Roaming Dedicated Support Team

• Provide CDG members with dedicated resources and
  project structure that will provide the
  following
• Substantial improvement in CDMA international
  roaming
• Quality
• Quantity
• Carrier support
• Stimulate much stronger involvement and
  commitment to roaming by carriers
• Create technical information repository, bulletin
  board, contact lists
• Facilitate inter-carrier meetings, field testing
• Establish and track industry-wide roaming goals
  and metrics
• Specialized training
• Documentation
• Service definition, test procedures,
  troubleshooting processes, recommended minimum
  requirements for handsets and infrastructure

CRX Providers

• CDMA Packet Data Roaming eXchange (CRX) Providers
  are in the business of facilitating CDMA data
  roaming for operators
• Similar function to GPRS Roaming Exchange (GRX)
  providers
• Allows an operator to only create a single data
  connection with the CRX provider and implement
  roaming with multiple operators
• CRX providers typically perform financial
  settlement between operators
• CRX providers are required to interconnect, so
  operators service by different CRX providers
  should still be able to implement roaming

34
Functions of a CRX provider

• Provides a secure backbone for operator
  interconnection
• Provides a proxy AAA so operators always send AAA
  transactions to same place
• Interfaces with operator billing system to
  perform settlement function
