  • Publication number: 20230397053
    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.

  • Patent number: 11785568
    Abstract: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.

  • Publication number: 20230292305
    Abstract: A method for configuring transmission order of uplink data, the method performed by a radio equipment (“RE”) of an access node. The RE has a RE controller (“REC”)-RE interface that communicatively couples the RE with a REC of the access node. The method includes receiving instructions from the REC that indicate a scheduling prioritization for transmission by the RE of uplink data between the RE and the REC over the REC-RE interface. The uplink data can be received by the RE on the radio interface. The method can further include transmitting the uplink data on the REC-RE interface according to the instructions, resulting in the scheduling prioritization of the uplink data.

  • Publication number: 20230275842
    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.

  • Publication number: 20230269193
    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.

  • Publication number: 20230209402
    Abstract: The present disclosure relates to methods and nodes in an integrated access and backhaul (IAB) network. In one aspect, a method for a local breakout, performed in a first network node of the IAB network is provided. The first network node is being in communication with a core network, and the method comprises providing a network connection between the first network node and a local data network having a first network address, receiving a data traffic, transmitted by a user equipment (UE), wherein the data traffic is destined for a central application server having a second network address and being in communication with the core network. If the at a traffic meets a requirement for the local breakout from the first network node, the method comprises forwarding the data traffic to a local application server of the local data network and receiving from the application server of the local data network, a selected part of the data traffic destined for the central application server.
