A method for assigning a service quality of a radio access network to a wireless connection includes: establishing, by a mobile application, the wireless connection to an application backend via an access node of the radio access network; and assigning, by a scheduler of the radio access network, the service quality of the radio access network to the established wireless connection. The mobile application transmits a quality function to the radio access network. The scheduler assigns the service quality depending on the transmitted quality function.

A method for operating a mobile Point-of-Sales (mPOS) application for executing a transaction includes: a Universal Integrated Circuit Card (UICC) card connected to a terminal device executes in interaction with the terminal device an application frontend of the mPOS application that provides, upon launch, an I/O interface with a human machine interface displayed by a touchscreen of the terminal device and a machine-to-machine interface; and the application frontend, for starting a transaction, captures transaction data associated with the transaction to be started via the human machine interface, reads further transaction data via the machine-to-machine interface from a transaction device separate from the terminal device and arranged close to the terminal device, generates a transaction authorization authorizing the requested transaction, and transmits the transaction authorization, the transaction data and the further transaction data via a connection to a remote backend server for completing the transaction.

A method for authenticating a user includes: an application frontend of a face recognition application, upon receipt of a face recognition request from an application backend of the face recognition application, causes a terminal device to activate a camera of the terminal device; the application frontend receives a video stream of a face of the user captured by the camera of the terminal device; the application frontend transmits the received video stream to the application backend; the application backend, upon receipt of the video stream, extracts a face characteristic of the user from the received video stream in real-time; and the application backend compares the extracted face characteristic with a stored reference face characteristic of the user and authenticates the user based on the extracted face characteristic matching the stored reference face characteristic.

A method for operating a communication network provides a sender of a distributed real-time application and a receiver of the distributed real-time application with a communication connection. The sender periodically transmits data packets to the receiver via the provided communication connection at a data rate exploiting a currently available bitrate of the communication connection. A node of the communication network anticipates the currently available bitrate to discontinuously drop and signals a difference of a dropped bitrate from the currently available bitrate to the distributed real-time application. The distributed real-time application immediately reduces the data rate according to the signalled difference.

Low-jitter communication connection for a distributed real-time application

A method for measuring a latency of a connection includes a sender of a distributed application that transmits a plurality of data packets to a receiver of the distributed application via a connection. A measuring application transmits a plurality of packets to an application server, receives a plurality of echo packets from the application server, where each echo packet is caused by a transmitted packet, and calculates time intervals between transmitting a packet and receiving the caused echo packet. The measuring application determines a transmission stop time of a transmitted data packet as a time point when the calculated time intervals rapidly shorten, and/or a transmission start time of a transmitted data packet as a time point when the calculated time intervals rapidly lengthen, and/or a packet rate of the transmitted data packets by counting the transmission start times or the transmission stop times during a second.

Reliable and accurate latency measurement

A method for operating a communication network includes a communication network providing a sender of a distributed real-time application and a receiver of the distributed real-time application with a communication connection, the distributed real-time application defining a minimum operable data rate. The sender periodically transmits data packets to the receiver via the provided communication connection at a data rate higher than the defined minimum operable data rate. The sender steadily determines a currently available bitrate of the communication connection, and adjusts the data rate to a data rate lower than the determined currently available bitrate by a data rate offset defined by the distributed real-time application. A node of the communication network learns the defined data rate offset and provides a guaranteed minimum bitrate of the communication connection higher than a booked minimum bitrate of the communication connection by the learned data rate offset.
