    摘要： For allowing a very efficient service marking a method for operating a network, especially a mobile network, is claimed, wherein an ADC, which is co-located in a PCEF or separate in a TDF, detects data flows for reporting data flow-specific information to a control-plane node according to service-specific information received from said control-plane node. The method is characterized in that said service-specific information is provided to the ADC on a service context basis, and the ADC reports the data flow-specific information in the form of a service detection result to the control-plane node according to the service-specific information on a service context basis after having detected a new data flow and checked or identified to what service the new data flow belongs. Further, an according network is claimed, preferably for carrying out the above mentioned method.

    摘要： A clustered femtocell network including a plurality of femtocell access points that are connected via a logical interface to a mobile network in order to provide user equipments with radio access to said mobile network, wherein said mobile network includes a Mobility Management Function - MMF -, is characterized in that a logical function - Proxy Mobility Management Function P-MMF - is provided that localizes mobility management of said user equipments in said clustered femtocell network, wherein said P-MMF intercepts and interprets mobility-related signaling between said MMF and said femtocell access points in such a way that it emulates towards said femtocell access points the behavior of said mobile network's MMF and towards said mobile network's MMF the behavior of said femtocell access points. Furthermore, a method for operating a clustered femtocell network is disclosed.

    摘要： A method for handling failure of a MME (Mobility Management Entity) in a LTE/ EPC (Long Term Evolution/Evolved Packet Core) network or an EPS (Evolved Packet System), wherein multiple UEs (User Equipment) are attached to a first MME, wherein said first MME stores first context information representing the UEs attached to said first MME, wherein said UEs are connected to one of multiple eNBs (evolved NodeB), wherein said eNB may communicate with said first MME and with at least one neighboring MME, and wherein said UEs may communicate with said first MME and with said at least one neighboring MME via said eNB, is characterized by the steps of detecting failure of said first MME, gathering information related to UEs attached to said first MME, wherein the step of gathering information is triggered by the detection of said failure, restoring at least parts of said first context information at one or several of said neighboring MME using the gathered information, and re-establishing network internal logical connections with said one or several of said neighboring MME using the restored first context information.

    摘要： The present invention relates to a method for congestion avoidance in a mobile communication network, wherein the mobile communication network comprises a sender (S) and a receiver (R), wherein one of them is located in a mobile access network of the mobile communication network, comprising the steps of a) Indicating a congestion in a data transmission of the mobile communication network between the sender (S) and the receiver (R), b) Providing a congestion notification (CN) further downstream in the direction of the data transmission path between the sender (S) and the receiver (R), c) Providing congestion notification information (CNI) on the data transmission path in opposite direction, d) Receiving and evaluating the congestion notification information and e) Initiating one or more congestion avoidance policies based on the evaluated congestion notification information, wherein the congestion notification (CN) according to step b) and the congestion notification information according to step c) are transmitted between mobile network entities (BS, IN, EE) on the same communication plane (UP) of the mobile communication network and wherein the congestion notification information (CNI) according to step c) is provided with a granularity level more coarse than the IP flow level to an action function for performing steps d) and/or e). The present invention relates also to a system for congestion avoidance in a mobile communication network.

    摘要： A method for supporting dynamic resource management in a backhaul network, wherein a resource management function is provided that includes an offline component and an online component for routing data traffic in the form of pipes, wherein said pipes include a path from an ingress switch to an egress switch of said backhaul network and an assigned capacity, wherein said offline component performs offline path computation based on expected traffic demands that are determined from one or more traffic matrices in order to compute offline computed paths for said pipes being represented in said one or more traffic matrices, wherein said expected traffic demands constitute claimable resources for said pipes, wherein said offline computed paths are installed in the backhaul network in order to configure said pipes, wherein initially only a fraction of the maximum allowable capacity that corresponds to the amount of said claimable resources is allocated as capacity for said pipes, wherein said resource management function allocates capacities to said pipes dependent on current data traffic, wherein in case excess traffic demands for one or more of said pipes - excess pipes - occur, because being beyond said expected traffic demands for said excess pipes, said excess traffic demands constitute opportunistic resources for said excess pipes, and wherein said online component performs online path computation in such a way that said online component uses unblocked claimable resources of one or more pipes different from said excess pipes in order to provide said opportunistic resources for said excess pipes.
