GSM Global Roaming Forum 5 TR-45.2, 13-Nov-2000, Boulder, CO Key Components For Interstandard Roaming Commercial arrangements: so that agreements, minimum services, etc. are agreed to in advance Networks: to ensure the ground-based infrastructure – which carries signaling, voice, and data messages - can communicate with each other. Billing: to ensure different systems for exchanging call detail records can interoperate in a timely manner. Terminals & Smart Cards: so that the customer’s phone can recognize and operate on systems unlike their home technology. Testing: to ensure individual components of roaming and also the entire process has been verified and is operating as planned. “One phone-one number, one terminal, around the globe and across technologies”
