Abstract: For efficiently handling network traffic via a fixed access, classification of UL data traffic in a communication device 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. The outgoing uplink data packets carrying the complementary identifier are assigned to the same traffic class as the incoming downlink data packets. For this purpose, the communication device is provided with a traffic classificator. In the reflective mode, the traffic classificator locally generates uplink packet classification rules by monitoring received downlink data packets.

Abstract: To handle network traffic, a Deep Packet Inspection (DPI) node receives, from a Policy and Charging Rules Function (PCRF) network node, packet inspection control data that maps a specific service to an identifier. The DPI node identifies that a data packet pertains to the specific service. The identifying comprises performing DPI on at least a data section of the data packet. The DPI node notifies the PCRF network node that the DPI node received the data packet and that the data packet pertains to the specific service. The DPI node marks the data packet with the identifier in accordance with the packet inspection control data received from the PCRF network node.

Abstract: A service class for a transmission of data packets between a service entity and a user equipment is selected from a plurality of service classes. A first transmission context is established between a core network node and the user equipment, and is associated with a first set of attributes for defining a first quality of service for the transmission. Furthermore, a second transmission context is established between an access node and the user equipment, and is associated with a second set of attributes for defining a second quality of service for the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node.

Abstract: A user equipment receives incoming data packets from one of a plurality of bearers. The incoming data packets comprise a first identifier indicating a source. The user equipment also detect outgoing data packets which include a second identifier indicating the source of the first identifier as destination of the outgoing data packet. The user equipment routes detected outgoing data packets which include the second identifier to the same bearer from which the incoming data packets having said first identifier are received. The detecting and routing is selectively activated on the basis of a control signal.

Abstract: In a mobile communication environment, the data traffic is mapped to a number of bearers. In a downlink direction, this is accomplished by filtering data packets on the basis of an identifier which is included into the data packets in response to packet inspection. In the uplink direction, a mirroring function is applied which detects incoming data packets, which are received on one of a plurality of bearers and have a first identifier, and outgoing data packets having a second identifier which is complementary to the first identifier. The outgoing data packets having the complementary second identifier are routed to the same bearer from which the incoming data packets are received.

Abstract: 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.

Abstract: 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.
