摘要： A method for use in a wireless communications system in which there is at least a first mode which controls the traffic to and from user terminals in a cell within the system, so that there is downlink traffic in the system. The first node transmits downlink traffic in radio frames, each of which comprises sub-frames. The first node performs measurements on pre-defined system indicators in at least said first cell, and based on the results of said measurements, the first node is allowed to autonomously decide to vary the number of available down link sub-frames used for down link traffic in said down link radio frames and also to vary the content of the down link sub frames which are used, said decision being valid for a time which is specified by the first node.

摘要： The present invention relates to a partitioning entity and a method for partitioning capacity in a communication network to avoid starvation of certain data traffic and to support services with different characteristics. The method of partitioning capacity comprises assigning communication links to a group associated with a time-varying group capacity to form a group of communication links. The group comprises a first sub-group and at least a second sub-group of communication links. Further, the method comprises allocating a non-zero fraction of the time-varying group capacity to the first sub-group of communication links of the group.

摘要： Delays associated with real-time, interactive communications are reduced. A communications device A engages in a real-time, interactive communication with a communication device B. User A provides digital content to be transmitted to device B. A real-time, interactive connection is established between A and B which takes a certain delay time. That delay time is compensated for so that user B receives A's digital content and can respond to it faster than B could without the delay time compensation. This faster response by the B to A's communication enhances the interactive, real time, conversational feel of their communication.
摘要翻译：与实时交互式通信相关的延迟减少。通信设备A与通信设备B进行实时的交互式通信。用户A提供要发送到设备B的数字内容。在A和B之间建立实时的交互式连接，该连接需要一定的延迟时间。该延迟时间得到补偿，以便用户B接收A的数字内容，并且可以比B更快地对其进行响应而不需要延迟时间补偿。 B对A的通信的这种更快的反应增强了他们的沟通的交互，实时，对话的感觉。

摘要： A method is described for associating a data packet (DP) with a packet bearer (PB) in a user equipment (UE1) of a communication network. The data packet is sent in a data flow from an application function of the user equipment, the packet bearer (PB) is established with the user equipment to transmit the data packet (DP) over the communication network towards a further entity, and the user equipment is adapted to establish different packet bearers. The method comprises the steps of identifying the flow with the data packet in a control entity of the communication network, determining the packet bearer for association with said flow from the different packet bearers in a policy function of the control entity, determining a routing level identification of the further entity, instructing the user equipment to install a packet filter based on the routing level identification, wherein the packet filter associates data packets comprising the routing level identification of the further entity with the determined packet bearer, providing the routing level identification to the application function, including the routing level identification into the data packet, and forwarding the data packet (DP) on the determined packet bearer (PB). A corresponding network, control entity, monitoring entity and computer program are also described.

摘要： A method of controlling the flow of an amount of data from a sending peer to a receiving peer of a predetermined communication protocol is described. The method comprises dividing the amount of data into a plurality of data segments, where the data segments are ordered in a sequence. The segments are sent to the receiving peer in the order of said sequence. The receiving peer acknowledges the correct receipt of a data segment and identifies the last correctly received data segment of the sequence that was received in the proper order of the sequence. The sending peer is arranged such that if it receives a threshold number of duplicate acknowledgements, it performs a retransmission. The threshold number that trigger a retransmission is an adaptive parameter determined based on the size of a receive window, the size of the receive window representing a number of data segments which can be stored in a buffer space at the receiving peer.

摘要： For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device (100) may be accomplished in a reflective mode by detecting identifiers of outgoing uplink data packets which are complementary to identifiers of incoming downlink data packets. The downlink data packets are already assigned to the traffic classes (50). The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class (50) as the incoming downlink data packets. For this purpose, the communication device (100) is provided with a traffic classificator (110). In the reflective mode, the traffic classificator (110) locally generates uplink packet classification rules (115) by monitoring received downlink data packets.
