Abstract: An apparatus suitable for at least to: select a cell in a low activity state, and; in the case the selected cell is the same as a serving cell while carrying out a state change to the low activity state, transmit a radio connection resume request to the selected cell; or in the case the selected cell is another cell than the serving cell while carrying out a state change to the low activity state, transmit a radio resume request to the selected cell with information on the location of the user device provided the information on the location has not been transmitted in relation to a cell change carried out in the low activity state; receive, as a response to the radio connection resume request, a radio connection resume request response, and carry out a radio connection resume for the data transmission.

Abstract: There is provided a solution for proactively transferring downlink data addressed to a terminal device from a data routing network element of a cellular communication system. According to an embodiment, a location of the terminal device is determined and an identifier associated with the determined location is delivered to the data routing network element. Then, the data routing network element may forward the downlink data towards the terminal device even before one or more services for the delivery of the downlink data to the terminal device have been completed.

Abstract: A method includes determining, by a source base station, based on at least one of a measurement report received from a terminal device and a mobility trajectory of the terminal device, a prepared cell list that includes a set of cells where the terminal device is capable of handover. The method includes sending at least one required context for the handover to the set of cells in the prepared cell list. The method also includes receiving acknowledgement from the set of cells. The method further includes sending a handover complete message, which contains the prepared cell list, to the terminal device. The prepared cell list provides a capability for the terminal device to make a number of handovers when the terminal device is within a coverage area of the set of cells.

Abstract: There is provided a solution for proactively transferring (206) downlink data addressed to a terminal device (120) from a data routing network element (e.g. S-GW) of a cellular communication system. According to an embodiment, a location of the terminal device is determined and an identifier associated with the determined location is delivered to the data routing network element. Then, the data routing network element may forward data to the eNB even before one or more services for the delivery of the downlink data to the terminal device have been completed.
