Summary

Recommendation ITU-T Q.3905 describes the test specifications for compliance testing against ITU‑T Q-Suppl.4 "Number portability – Capability set 1 requirements for service provider portability (All call query and Onward routing)". There are mandatory and optional test suites which can be used for testing of:

–           different network scenarios of number portability (the onward routing and all call query);

–           signaling requirements for establishing the number portability;

–           interconnection among providers and call routing between ported and non-ported end-users.

Additionally, this Recommendation gives the operational procedures for organizing a particular test event.
