The invention relates to a wireless access telecommunications network system comprising at least an SA-cell with which a terminal in an active mode is configured to have an established data connection and an LA-cell on which the terminal in an idle mode is configured to camp. A method for the terminal to obtain at least LA-cell system information and SA-cell system information includes, when the terminal is in the idle mode and an LA-cell radio interface of the terminal is enabled, the terminal receiving at least a first part of the LA-cell system information and at least a first part of the SA- cell system information from the LA-cell via the LA-cell radio interface.
