Abstract: A method is disclosed for a radio access network control node operating in a communication network having an associated user device, wherein the user device has an ongoing application service session with an application server via the communication network. The method includes detecting that a trigger condition is met for the user device, the trigger condition indicating an upcoming communication interruption in relation to the application service session. The method also includes causing implementation of a temporary transmission rate adjustment of the application service session, wherein the temporary transmission rate adjustment provides a radio access channel margin accommodating the upcoming communication interruption. In some embodiments, causing implementation of the temporary transmission rate adjustment includes transmitting an adjustment command to the user device and/or the application server. Corresponding methods for a user device and an application server are also disclosed.

Abstract: A method for accommodation of latency variation in a communication network is disclosed. The method comprises identifying that a service is currently associated with a user device associated with the communication network, wherein a deviation between a latency requirement of the service and an internal latency performance of the communication network is bounded, predicting an upcoming reduction of communication network throughput for the user device, and providing a rate adaptor associated with the service with a feedback indication in response to predicting the reduction of communication network throughput, wherein the feedback indication is for rate reduction of the service. In some embodiments, the prediction and provision are performed only for user devices associated with services with bounded deviation between the latency requirement of the service and the internal latency performance of the communication network.

Abstract: A method for latency control in a communication network is disclosed. The method comprises identifying that a service is currently associated with a user device associated with the communication network, wherein a deviation between a latency requirement of the service and an internal latency performance of the communication network is bounded, and dynamically adjusting a configuration of the communication network for the service. In some embodiments, the dynamic adjustment is performed only for user devices associated with services with bounded deviation between the latency requirement of the service and the internal latency performance of the communication network. In some embodiments, dynamically adjusting the configuration of the communication network comprises controlling the communication network to provide latencies below a maximum latency threshold for the service. In some embodiments, the dynamic adjustment of the configuration of the communication network is based on the current traffic load.

Abstract: A method for latency control in a communication network is disclosed.

In some embodiments, the dynamic adjustment is performed only for user devices associated with services with bounded deviation between the latency requirement of the service and the internal latency performance of the communication network.

Abstract: An antenna device for a hand-portable radio communication unit including a casing with a ground plane means cooperating with the antenna device. The antenna device comprises first and second radiating elements (1a, 1b) being tuned to different resonant frequencies and having a common feed point (1c). The radiating elements (1a, 1b) are disposed in a compact arrangement on a support means (3) so as to be confined entirely in the casing (2).
