The scope of this document is to define a methodology for testing, and maintaining in the presence of faults, the inter-Public Mobile Network (PMN) international roaming facility.
The structure for testing international roaming is recommended to follow a three -stage approach:
- Stage 1 – Interface self-certification testing for different protocols like MAP, CAMEL Application Part (CAP), IP, Diameter, GPRS Tunneling Protocol (GTP) and HTTP/2.
- Stage 2 – Exchange of numbering and addressing data, procedures for operation and maintenance, fault reporting, etc.
- Stage 3 – End-to-end functionality / capability performance testing.
