摘要： In a mobile communication network, data traffic is mapped to a non-guaranteed bit rate bearer (50, 60) established between a gateway node (100) and a mobile terminal (200). The non-guaranteed bit rate bearer comprises a first sub-bearer (51, 61) between the mobile terminal (200) and an access node (120), a second sub-bearer (52, 62) between the access node (120) and an intermediate gateway node (110), and a third sub-bearer (53, 63) between the intermediate gateway node (110) and the gateway node (100). Releasing of the third sub-bearer (53, 63) is controlled on the basis of the first sub-bearer (51, 61) and/or the second sub-bearer (52, 62) being released.

摘要： User identity token for identifying a user of a communication network A first node (13), e.g., a policy controller of a communication network, receives a request (101) from a second node (15), e.g., an application server for providing a service in the communication network. The request (101) includes a transport address assigned to a user of the communication network. Further, the first node (13) accesses mapping data (31) relating the transport address to a subscription identity of the user and determines a user identity token which is mapped to the subscription identity of the user and masks the subscription identity. The first node (13) then sends a response to the second node (15). The response (102) includes the user identity token.

摘要： For separating data traffic in an uplink (UL) edge node (100) of a communication network, UL one or more packet filters (110) are provided in the UL edge node (100). The packet filters (110) identify data packets in UL traffic from the UL edge node (100). Gating data associated with the packet filters (110) are evaluated, e.g. to derive gating control signals (GC1, GC2, GC3) of the individual packet filters (110). Depending on the evaluation of the gating data, the identified data packets are discarded.

摘要： A method and device for determining a parameter (RTO) associated with a retransmission time-out feature in a data unit transmitter implementing a protocol (TCP) that provides an acknowledgment feature and a retransmission time-out feature, where according to one aspect decreasing values of the round trip time (RTT) are treated differently with respect to their influence on a mean deviation parameter (RTTVAR) than increasing values of the round trip time, where according to another aspect weight values (g, h, w) used in the determination of the parameter (RTO) are chosen such that at least one of them is time variable, and where according to a further aspect the parameter (RTO) is also calculated on the basis of a value (SR) indicative of the number of spurious time-outs in the communication.

摘要： The invention relates to a method and a device for improving the processing time of received data in packet oriented applications during a transmission via communication networks, in particular via an IP network and a mobile communication network such as the Global System for Mobile Communication (GSM), Universal Mobile Telecommunication System (UMTS) or General Packet Radio Service (GPRS). The received data packets of the second protocol layer, for instance, the RLP frames, are combined to form data packets of the first protocol layer, for instance to PPP frames, directly by the receiver in the second protocol layer. The completely and correctly combined data packets are then released to the first protocol layer. During the release of the data packets to the first protocol layer, a difference is made between two modes. The intra-flow mode is a mode, wherein all completely generated data packets are released, i.e. independent from whether the data packets belong to the same or to two different data flows. In contrast thereto, a difference is made in view of the inter-flow mode. In said mode only the completely generated data packets belonging to different data flows are released to the first protocol layer.

摘要： A communication device and method is provided, for which, when having implementations of first protocol that specifies different reliability levels for sending PDUs of a second protocol, where the second protocol specifies segmentation of PDUs of a third, higher layer protocol, a capability is introduced for setting the reliability level of second protocol (L2_ARQ) PDUs differently for second protocol PDUs belonging to a defined data structure containing such second protocol (L2_ARQ) data units. The defined data structure can be a higher layer protocol data unit or the send window. Thereby the delay caused by retransmission of second protocol data units can be reduced significantly.

摘要： The present invention relates to a methods and network nodes for controlling resources of a service session in a communication network as well as to a corresponding system and computer program to improve the handling of resources in the network, and particularly to optimize signaling in the network. The method for controlling resources for a service session by a policy and charging system in a communication network comprises the steps of obtaining, at a first network node, a request including service session data indicating the type of service; determining, based on the service session data obtained at said first network node, a resource type to be assigned to said service; and sending to a second network node an indication of said resource type assigned to said service, according to which resource type it is determined when a service session associated with said service is terminated.
