MTTR (Mean Time To Recovery)
Mean Time To Recovery (or Repair) is the average time required to restore a failed system or service to normal operation. MTTR is a core operational SLI alongside availability and Mean Time Between Failures, and is improved by good monitoring, automated runbooks, redundant architectures, and well-rehearsed incident response.

MTTR in context
The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.
To place MTTR in the wider telecom-security picture, review MSSP, MDR, Capacity Planning, DRP, Man-in-the-Middle (MITM) and MNO: each entry cross-references back to this page so you can walk the topic in either direction.
