For allowing a reliable communication between the wireless part and the core network part via the fixed line network a method for operating a network, especially for policy control within the network, is provided, wherein the network includes a mobile network and a fixed line network, wherein the mobile network includes a wireless part and a core network part and wherein the mobile network and the fixed line network cooperate for providing communication between the wireless part and the core network part via the fixed line network. The method is characterized in that information regarding the wireless part will be provided via the mobile network to the fixed line network for controlling the communication within the fixed line network. Further, a corresponding network, preferably for carrying out the above mentioned method is disclosed.

For allowing a simple and reliable differentiation of UEs behind a GW from an AF side a method for providing access of an User End device (UE) to a service provided by an Application Function (AF) within a network structure is claimed, wherein the UE is authenticated by a Gateway (GW) to which the UE is attached and which provides access to the AF via a Broadband Access Network (BB Access Network). The method is characterized in that the GW informs a state database (SDB) on service flow requests to or from the authenticated UE towards the AF, that the GW additionally sends NAT (Network Address Translation) or NAPT (Network Address and Port Translation) binding information of a respective NAT or NAPT binding created by the GW regarding the authenticated UE and a respective service flow request to the SDB and that the SDB sends the NAT or NAPT binding information or an UE identifier to the AF, so that the AF—after having received the service flow request from the GW—can correlate the authenticated UE with the service flow request. Further an according network structure is claimed, preferably for carrying out the above mentioned method.
摘要:
A method for operating a flow-based switching system in a network, including at least one network node designed to transport incoming network packets, in particular a switch (20) or a router, wherein the incoming network packets are matched to flows according to predefined policies, wherein a dynamic flow table (40)—primary flow table (50)—containing information about the flows' properties is computed inside the network node or externally and stored in a memory of the network node, is characterized in that another dynamic flow table (40)—backup flow table (60)—is computed and maintained in parallel, wherein the backup flow table (60) is more coarse grained than the primary flow table (50), and wherein the network node switches between employing the primary flow table (50) or the backup flow table (60) depending on the status of predefined observables. Furthermore, a corresponding flow-based switching system is disclosed.

A method for supporting distribution of warning messages, is characterized in that an NGN (Next Generation Network) infrastructure is employed for distribution, wherein the infrastructure includes a plurality of network elements including endpoints, wherein a hierarchical architecture is defined for the network elements, wherein groups of network elements including endpoints with specific characteristics are defined, wherein each of the network elements provides its group membership information to at least one higher-tier network element, and wherein at least one group warning controller is provided that, upon receiving a request from a source node, generates a warning message for one or more target groups and forwards the warning message to lower-tier network elements of the respective target group or groups towards endpoints.
摘要:
A method for supporting a connection between a communication device and a destination device in a target network over intermediate network nodes, in particular in the context of Internet Protocol based communication, wherein data between the communication device and the destination device is transmitted via a tunnel established between the communication device or a base station connected to the communication device, as a first tunnel endpoint and a gateway in the target network as a second tunnel endpoint. One or more dummy packets are sent via the tunnel from the first tunnel endpoint towards the second tunnel endpoint, information is encoded in the packet headers of the one or more dummy packets, and at least one of the intermediate network nodes, upon receiving the one or more dummy packets, performs the steps of detecting and/or decoding the encoded information and performing a predefined action dependent on the encoded information.
摘要:
For allowing an enhancement of diversity of network applications in a simple way a method for operating a network, especially an IP (Internet Protocol) network, is claimed, wherein a local network is in connection with the network via a gateway and wherein a UE (User Equipment) of the local network is performing a session setup by communicating with a functional entity of the network in order to communicate with or to start a UE-related and/or session-related application. The method is characterized in that the application is communicating with a local network controller, wherein the network controller is receiving a UE-related and/or session-related parameter (LID—Local Identifier) from the application for locating a UE and/or a specific session within the local network based on the received parameter. Further, an according network is claimed, preferably for carrying out the above mentioned method.
