| 摘要 |
An apparatus and method for handling service data units transmittable in a downlink from a core network of a mobile telecommunications system via an radio interface (333) to a radio access network and from said radio access network via an radio interface (206) to an user equipment, wherein segmentation is blocked in said radio access network in case of an inactive segmentation state, and comprising means for receiving one or more data transport blocks comprising a transport format indicator and a segmentation state indicator, wherein the segmentation state indicator is being signalled to a segmentation/reassembly layer of the radio access network and the requested mode for said radio interface (206) between the user equipment and the radio access network is a transparent mode, and means (256) responsive to said segmentation indicator for blocking segmentation in said segmentation/reassembly layer in case said indicator indicates an inactive segmentation state and for permitting segmentation in said segmentation/reassembly layer in case said indicator indicates an active segmentation state. |
