A method and apparatus for taking measurements in a mobile
telecommunications system are disclosed, the system comprising a network
of a plurality of cells and at least one user equipment device. The
method comprises, at the user equipment device, receiving a measurement
control set-up command and, in response the user equipment device,
setting up the measurements. Then it monitors for a change in state of
the UE and, in response to a change in state, issuing a measurement
control pause command and, in response, the user equipment device
stopping taking measurements, and maintains the measurement settings
initialised previously. The device then monitors for a change in state of
the UE and, in response to a change in state, issuing a measurement
control resume command and, in response, the user equipment device
resumes taking measurements with the maintained measurement settings.
