摘要： Services are provided at least indirectly by a network operator. A method for providing and/or using the services includes: providing a communication link between a network of the network operator and a user equipment (UE); transmitting a first communication address of a service controller of the network operator to the UE, wherein the service controller manages an access to services that can be used by the UE; sending, by the UE, a request to access a particular service of the service controller to the first communication address of the service controller; transmitting a message comprising a second communication address of the service from the service controller to the UE; and sending, by the UE, a request to start the service to the second communication address of the service.

摘要： A method for transmitting multiple data streams of different communication services over a multipath transmission system includes: providing data to be transmitted, wherein the data to be transmitted comprises first data and second data; detecting, out of a plurality of communication services, a first communication service the first data belongs to and a second communication service the second data belongs to; mapping the first data to a first data stream and the second data to a second data stream based on the first and second detected communication services; scheduling transfer of the first data stream and the second data stream based on the first classification parameter assigned to the first and second communication services; and scheduling transmission of the first data and the second data to the destination communication device based on the at least one second classification parameter assigned to the first and second communication services.

摘要： A computer-implemented method optimizes a routing of data traffic in a communications network by using a quantum concept processor. A set of potential short communication paths among possible communication paths between respective origin nodes and respective destination nodes of captured traffic demands is specified. The edges within the set of potential short communication paths are assigned a respective usage capacity limit. Fractional capacity usages of the edges are calculated based on respective usage capacity limits of the edges. The calculated fractional capacity usages are formulated as terms of a quadratic stress function. An optimized routing is determined by using a quantum concept processor, thereby selecting for each traffic demand one short communication path from the set of potential short communication paths such that the quadratic stress function is minimized.
