1. A method comprising: in a terminal in a radio access network, receiving measurement configuration information from an access network element in the radio access network; performing measurements of terminal-related network performance parameters using the measurement configuration information; and transmitting to a network performance analysis and/or control element via the access network element, the measurements of the terminal-related network performance parameters via a combined network performance report, wherein the combined network performance report is formed by attaching access network-related network performance parameters measured at the access network element, to the measurements of the terminal-related network performance parameters, and the access network-related network performance parameters comprise parameters specific for minimization of drive tests for network performance monitoring.
