A network connection recovery method and apparatus, and a communication system. Where a radio link failure occurs in a primary base station but a signalling radio bearer of a secondary base station isstill available, or where a physical layer problem or a random access problem occurs in a primary cell but a secondary cell is still available, a user equipment reports information about the primarybase station and/or primary cell failure, or autonomously recovers the primary base station and/or the primary cell, so that the cell or base station where the radio link failure occurs can be changedmore quickly, thereby recovering a connection with a network side, and reducing data loss.
