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.

1-47. (canceled)
An apparatus comprising:
- at least one processor, and
- at least one memory comprising a computer program code, wherein the processor, the memory, and the computer program code are configured to cause the apparatus to:
- receive, in a first network element from a second network element of a cellular communication system, a paging request for a terminal device;
- in response to receiving the paging request, determine whether or not the terminal device is located in a control area of the first network element, the control area comprising at least one cell of the cellular communication system;
- upon determining that the terminal device is located in the control area, transmit of a notification message to the second network element, and
- after transmission of the notification message and before a service for the terminal device has been fully configured for data transmission in the first network element, receive in the first network element payload data associated with the service.
An apparatus comprising:
- at least one processor, and
- at least one memory comprising a computer program code, wherein the processor, the memory, and the computer program code are configured to cause the apparatus to:
- detect, in a data routing network element of a cellular communication system, that downlink data addressed to a terminal device of the cellular communication system exists;
- in response to said detecting, transmit of a notification message causing paging of the terminal device;
- as a response to the notification message, receive a response notification message identifying a first network element controlling a control area comprising at least one cell, and
- transmit, on the basis of the received response, said downlink data to the first network element before a service between the data routing network element and the terminal device and associated with said downlink data has been fully configured.
An apparatus comprising:
- at least one processor, and
- at least one memory comprising a computer program code, wherein the processor, the memory, and the computer program code are configured to cause the apparatus to:
- detect, in a network element of a cellular communication system, that downlink data addressed to a terminal device of the cellular communication system exists;
- in response to said detecting, determine a cell where the terminal device is located, and
- upon determining the cell, transmit a notification message to a data routing network element of the cellular communication system, wherein the notification message comprises an identifier associated with the determined cell and is transmitted before a service associated with said downlink data has been fully configured between the network element and the terminal device.
