Updated Key Messages: 6G Architecture and Migration Options – An Operator View

Following on from the release of its ‘6G Architecture and Migration Options – An Operator View’ publication in June 2026, this updated operator guidance has been issued in conjunction with the upcoming 3GPP plenary meeting this September.

NGMN has highlighted that several important areas still need to be addressed to ensure MRSS’ suitability as the preferred solution for 6G migration. NGMN further recommends that, should migration options beyond MRSS be needed, these should be guided by deployment need, hardware impact, implementation feasibility, total cost of ownership (TCO) implications and overall commercial viability to justify the additional standardisation, implementation, and operational complexity introduced by other migration options.
