A wireless network with distributed medium access control allows establishing of a virtual channel between a source node and a destination node via at least one intermediate node. The virtual channel may be established for the entire duration of a communication between the source node and the destination node, and, to establish the virtual channel, a request handler can transmit a virtual channel request, requesting an allocation of transmission resources for the virtual channel. Based on the virtual channel request, a virtual channel confirmation can be generated by the destination node and can be returned to the source node, indicating an allocation of the resources for the virtual channel. A communication handler can then transmit data from the source node to the destination node using the available transmission resources.

Resource reservation in a wireless network with distributed medium access control

In order to transmit data packets between a wirelessly connectable communications device and a communications partner, particularly during a handover process, the invention provides that when a first wireless transmission path is available, an availability of at least one additional wireless transmission path is detected. Based on the detection, a specific assignment schema, via which at least one portion of the data packets is assigned to each of the transmission paths, is selected according to specific transmission requirements and/or to a transmission protocol to be used for transmitting the data packets. An address specification specific to the transmission path is then assigned to a respective data packet that is assigned to a transmission path. By using the assigned address specifications, the data packets are transmitted via the different transmission paths between the communications device and the communications partner according to the selected assignment schema.
