摘要： A method performed by a network node includes the network node receiving, from a first portion of a service chain, a packet having a header portion that includes a first service chain path ID and a metadata field. The method further includes the network node retrieving, according to one or more predefined rules, one or more tags included in the metadata field. The method further includes the network node generating a second service chain path ID based on the one or more retrieved tags. The method further includes the network node replacing the first service chain path ID by inserting the second service chain path ID in the header portion, where the packet is forwarded, to a second portion of the service chain, in accordance with the second service chain path ID.

摘要： 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). QoS policy is then optimized (122), separately for each classified cell group, to meet the QoE targets. The optimized QoS policy is applied (124) to a new UE entering a cell.

摘要： Systems and methods are disclosed herein for User Equipment (UE) assisted data collection for mobility prediction. In one embodiment, a method performed by a UE for UE-assisted data collection for mobility prediction comprises receiving, from a network node of a cellular communications system, a UE trajectory prediction model for predicting a UE trajectory. The method further comprises executing the UE trajectory prediction model to generate a predicted trajectory for the UE, comparing the actual UE trajectory to the predicted UE trajectory, and sending, to a network node of the cellular communications system, a result of the comparison of the actual UE trajectory to the predicted UE trajectory. In this manner, mobility prediction performance is improved.

摘要： 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. (figure 2)
