Abstract

A User Equipment, UE, performs cell measurement and evaluation 64 on another frequency or system during a Radio Resource Control, RRC, state transition from a first state 52 to a second state 54, where a cell measurement is not normally possible in the first and second states. Cell measurement and evaluation is performed during a transition to a CELL_FACH state to identify a suitable E-UTRAN cell for possible cell reselection. UE camped in UTRAN connected state, receives a Radio Bearer Reconfiguration message and disconnects from the network to perform reconfiguration 56. The UE performs cell selection 58 and camps on a cell and monitors the FACH 60. As the UE is disconnected from the network it has more time to perform cell measurements and evaluation 64 on Long Term Evolution, LTE, frequencies to search and find a suitable E-UTRAN cell 66. Prior to performing cell measurement and evaluation, measurement conditions 62 may need to be satisfied, including: determining that measurement occasions are not available in the CELL_FACH state, determining that discontinuous reception is not available in the CELL_FACH state, determining that CELL_FACH measurements to LTE is not enabled, or, determining that there is suitable coverage on another frequency or system.
