Abstract: Wireless network cells are classified into groups based on radio and network conditions in the cells. Quality of Service, QoS, policy optimization is then performed per each classified cell group, by selecting more or less stringent predetermined rules until a target Quality of Experience, QoE, is met, at least for the highest priority traffic. To classify the cells into groups, the radio and network parameters collected (110) are ranked (112) by their influence on QoE. Based on this ranking, only a few of the most impactful parameter are selected (114). The range of values of each parameter is then divided (116) into a plurality of ranges, for example by the ability of the parameter, when within each range, to impact service quality. Cells are then classified (118) into groups based on the same parameters within the cells falling into the same value ranges. QoE targets for at least high priority traffic classes are obtained (120).

Abstract: A method, performed by a first node (111). The first node (111) operates in a communications network (10). The first node (111) determines (202) a predictive model of a future need to page a device (133) operating in the communications network (10). The first node (111) then outputs (204) a first indication. The first indication is based on the determined predictive model. A second node (112) operating in the communications network (10) obtains (301) the first indication, and predicts (302), based on the obtained first indication, the future need to page the device (133). A third node (113) obtains (402) a third indication from the second node (112). The third indication indicates the predicted future need to page the device (133) operating in the communications network (10). The third node (113) then determines (403), based on the obtained third indication, whether or not to page the device (133).

Abstract: Systems and methods to enable 5G system support for conveying time synchronization are provided. In some embodiments, a method performed by a wireless device for conveying external time domain information is provided. The method includes receiving a message in a first time domain used by the wireless device, the message comprising external time domain information; determining information about a second time domain based on the external time domain information; and conveying information about the second time domain to another node.

This minimizes the RAN and/or gNB impact and adds the potential for multiple time domain support.

Abstract: A de-jitter function for holding-and-forwarding packets such that the packets are delivered with an agreed fixed latency. The de-jitter function can be placed at the edge of a virtual 5G TSN switch (e.g. the de-jitter function can be deployed as part of a UPF for uplink (UL) packets and/or it can be deployed as part of a user equipment (UE) for downlink (DL) packets). By using the de-jitter function, the TSN can consider the wireless network as having a consistent, deterministic latency with no jitter.

Abstract: Traffic forwarding policy determination in a wireless communication system A node (310) of the wireless communication network receives first data indicative of estimated QoE levels of data traffic in the wireless communication network. The data traffic is subject to QoS rules enforced by one or more nodes of the wireless communication network. Further, the node (310) receives second data indicative of QoS statistics observed in association with the QoE levels. Based on the first data and the second data, the node (310) determines a traffic forwarding policy for the data traffic. The traffic forwarding policy defines QoS rules which, according to the observed QoS statistics, are expected to ensure that a QoE target is met.

Based on the correlation, the access node controls a connection of the user equipment with the cellular network. This may involve deciding whether to release the user equipment to idle mode or paging of the user equipment.
