Partitioning resources on a target side of a handover of a user equipment based on data traffic indication
It is described a method for partitioning radio transmission resources within a telecommunication network. The method includes (a) preparing a handover of a user equipment from a source access point being assigned to a source side of the telecommunication network to a target access point being assigned to a target side of the telecommunication network, (b) transferring a pre-announcement message from the source side to the target side indicating the handover, wherein the pre-announcement message is indicative for the amount of data traffic being associated with the user equipment, and (c) partitioning the radio transmission resources on the target side based on the pre-announcement message. It is further described a source side network element and a target side network element for controlling a partitioning of radio transmission resources within a telecommunication network. Furthermore, a computer program for controlling the above described method is described.

the target access point of the user equipment is a target relay node being connected to a target base station and
the source base station and the target base station are the same entity within the telecommunication network.
10. The method as set forth in claim 1 , further comprising
carrying out the handover of the user equipment from the source access point to the target access point, and
partitioning radio transmission resources on the source side based on the amount of data traffic that is associated with the user equipment.
11. The method as set forth in claim 1 , wherein
partitioning radio transmission resources on the target side comprises allocating radio transmission resources for the user equipment, and
after partitioning the radio transmission resources and before carrying out the handover of the user equipment the allocated radio transmission resources are used for another radio data transfer.
12. The method as set forth in claim 1 , wherein the pre-announcement message comprises an identification of the target side of the telecommunication network.
13. A non-transitory computer readable medium embodying a computer program for partitioning radio transmission resources within a telecommunication network, the computer program, when being executed by a data processor, is adapted for controlling the method as set forth in claim 1 .
14. A source side network element comprising:
at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the source side network element to at least:
control a partitioning of radio transmission resources within a telecommunication network in connection with a handover of a user equipment from a source access point being assigned to a source side of the telecommunication network to a target access point being assigned to a target side of the telecommunication network, comprising
transmitting a pre-announcement message from the source side to the target side indicating the handover of the user equipment,
wherein the pre-announcement message is indicative for the amount of data traffic being associated with the user equipment,
wherein the preannouncement message is adapted for controlling the partitioning of the radio transmission resources on the target side, and
wherein the pre-announcement message indicates a length of time that the partitioning of the radio transmission resources is valid.

a source base station or
a source relay node being connected to a source base station.
16. The source side network element as set forth in claim 14 , further comprising
carrying out the handover of the user equipment from the source access point to the target access point, and
partitioning radio transmission resources on the source side based on the amount of data traffic that is associated with the user equipment.
17. A target side network element, comprising:
at least one processor; and
at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the target side network element to at least:
control a partitioning of radio transmission resources within a telecommunication network in connection with a handover of a user equipment from a source access point being assigned to a source side of the telecommunication network to a target access point being assigned to a target side of the telecommunication network, comprising
receiving a pre-announcement message from the source side to the target side indicating the handover of the user equipment, wherein the pre-announcement message is indicative for the amount of data traffic being associated with the user equipment,
