Abstract: In a telecommunications system a larger higher layer data unit is segmented into smaller segments on the lower layer. A segmentation length information is used to indicate the lengths of the segments in a lower layer protocol data unit. Specific values of segmentation length information are employed to indicate, when necessary, special information about the upper layer data unit, such as whether the upper layer data unit ends in the current data segment in the lower layer protocol data unit or continues to the next lower layer protocol data unit. This information is needed in the receiver to correctly assemble the segmented data.

Abstract: 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.

Abstract: In a method for scheduling communication resources, data-flow-specific information relating to a next scheduling period for a set of data flows is determined in a first entity. The determined data-flow-specific information is submitted to a second entity, where communication resource properties for communication resources are estimated. Communication resources in the next scheduling period are allocated in the second entity based at least on said data-flow-specific information and said communication resource properties.

Abstract: The idea of the present invention is to enable the transmission of control information via several logical channels and to select the transmission channel dynamically by using a predefined selection rule. There are at least two logical channels that can be selected for the transmission of information. These logical channels should preferably include at least one signalling channel which is allocated in a connection-specific manner. The signalling channels which are allocated in a connection-specific manner can be signalling channels which use the capacity of the traffic channel or independent signalling channels which are allocated separately from traffic channels. At least one of the logical channels available for selection should preferably also be a shared channel allocated to several connections for joint signalling.

Abstract: A series of logical channel identifiers LCIDs, each associated with one radio link service profile RLSP, is stored in a local memory. The local memory is accessed whenever a LCID is taken into use for identifying an active logical channel, and each RLSP includes a set of radio link service parameters at least one of which is a quality of service parameter. A first data packet bearing a LCID and establishing a flow is received over a wireless logical channel. The local memory is accessed to determine if an RLSP is associated with the LCID of the first data packet. For the case where an RLSP is not associated with the LCID in the local memory, the LCID is associated with a designated default RLSP, and the first data packet is processed using the designated default RLSP. Predetermined and custom RLSPs are also described, as are methods, devices, programs, an integrated circuits embodying the invention.

Abstract: A method includes receiving on an uplink communication path one or more packets from a user equipment, and determining radio link resources to be allocated on the uplink communication path for the user equipment. The determination is based at least in part on an information content of the one or more packets. The determined radio link resources are allocated. Another method is disclosed including receiving at a network access element on a first uplink communication path a bandwidth request from a user equipment. The bandwidth request is for a second uplink communication path used for packet traffic from the user equipment to the network access element. Radio link resources to be allocated on the second uplink communication path for the user equipment are determined, the determination is based at least in part on the bandwidth request. The determined radio link resources are allocated on the second uplink communication path.

Abstract: The invention concerns the control of connections in cellular telecommunication systems. According to the invention, the available radio resources are controlled by allowing only certain conbinations of transport formats to be used by a single user. The inventive method restricts the combinations of bearer bit rates which can be used, without strictly limiting some bearers from using highest bit rates. This inventive approach allows flexible overall control of radio resources, while retaining the possibility of bearers to select between different bit rates.
