摘要： The invention relates to a method between a communications device ( 110 ) and a communications network, which communications network generally provides at least a direct cell access mechanism and an alternative cell access mechanism for the communications device for uplink access to the communications network. The method comprises determining by the communications network and indicating ( 230 ) to the communications device ( 110 ) whether the direct cell access mechanism can at a given time be provided. This being the case, the communications device can directly start sending user data ( 150 ) on a traffic channel. In a situation in which the direct cell access cannot be provided, it is indicated to the communications device that the alternative cell access mechanism should be used.

摘要： The invention provides a method and system for a network which includes a plurality of nodes, preferably routers, a shared network segment for communication between the nodes, and several multicast channels in the shared network segment on which the nodes, preferably routers, can send multicast messages to the other nodes. A specific multicast channel is provided on which the nodes can send specific start multicast messages to other nodes, wherein a node which starts a protocol application, preferably a routing protocol application such as Open Shortest Path First (OSPF) protocol, is adapted to send a multicast start message on the specific multicast channel. Another node, preferably a router, receiving this start message is adapted to validate the authenticity of the start message and to send a response message.

摘要： A channel inverse multiplexer/ multiplexer IMUX/MUX 14a of a MAC sublayer 14 of a UTRAN RNC 11 for providing to a UE 18 traffic communication signals including in general both control and user data at a higher rate than the UE can accept over a single channel. The channel IMUX/MUX performs inverse multiplexing of traffic for downlink, and multiplexing of traffic on uplink, and does so in a way that is transparent to all other layers/ entities of the UTRAN 11 17 and to the UE 18.A channel inverse multiplexer/ multiplexer (IMUX/MUX) (14a) of a MAC sublayer (14) of a UTRAN RNC (11) for providing to a UE (18) traffic (communication signals including in general both control and user data) at a higher rate than the UE can accept over a single channel.

摘要： PCT No. PCT/FI95/00673 Sec. 371 Date Jun. 9, 1997 Sec. 102(e) Date Jun. 9, 1997 PCT Filed Dec. 8, 1995 PCT Pub. No. WO96/18248 PCT Pub. Date Jun. 13, 1996In a mobile communication system, two or more parallel traffic channels are allocated for high-speed data transmission over the radio path. Different channel numbers are assigned to these parallel traffic channels for the duration of the connection. The data of a high-speed data signal is inserted at the distribution point of the transmission end into frames each of which is provided with a channel number indicating the parallel traffic channel used for the transmission. The frames transmitted in a traffic channel always contain the same channel number during the whole call. The frames are divided into parallel traffic channel in the sequential order according to the channel numbering. At the reception end the data contained in the frames is reassembled into a high-speed data signal in the sequential order according to the channel numbers in the frames. Frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number. Consequently, the allowed delay offset between the traffic channels will increase with the number of the frame numbers, and the order of the frames will be maintained under any circumstances.
