Abstract: A technique for signalling activation or deactivation of a data-over-non-access-stratum, NAS, transmission scheme is disclosed, the transmission scheme being for transmitting data packets over the NAS between a terminal and a base station, and being started in an idle mode. In a method aspect, there are steps of determining a trigger condition indicating a need for the data-over-NAS transmission scheme, and signalling an indication for activation or deactivation in response to fulfilment or non-fulfilment of the determined trigger condition. In another method aspect, there may be steps of receiving the indication for activation or deactivation, and activating or deactivating the data-over-NAS transmission scheme in response to the signalled indication.

Abstract: Congestion level configuration for radio access network congestion handling A radio access network node (100) of a cellular network receives an indication of one or more criteria. The criteria which define one or more congestion levels. Further, the radio access network node (100) receives, for each of the one or more congestion levels, an indication of a congestion handling policy associated with this congestion level. Depending on the one or more criteria, the radio access network node (100) determines whether one of the one or more congestion levels is reached. In response to determining that one of the one or more congestion levels is reached, the radio access network node (100) applies the congestion handling policy associated with this congestion level.

Abstract: In a mobile network comprising a plurality of base stations and a gateway, a user equipment may perform a handover from a source base station to a target base station. By control signalling, the handover may be notified from the target base station to a control node of the mobile network and then to the gateway so that the gateway may switch to a data path which connects the target base station and the gateway. The notification of the handover may be delayed at the target base station or at the control node, by starting a timer and sending the control signalling for initiating the path switching after expiry of the timer.

Abstract: A method aims at controlling parameters used by communication terminals of a telecommunication system which enables discontinuous reception. The discontinuous reception involves DRX cycles during each one of which a communication terminal wakes up at least once to monitor a downlink control channel.
