The present invention relates to a method for transmitting an uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: transmitting the UL data to a first node based on a first Quality of Service (QoS) flow to data radio bearer (DRB) mapping rule; receiving, from the first node, a handover command including information related to a second QoS flow to DRB mapping rule; transmitting the UL data to the first node based on the first QoS flow to DRB mapping rule, until an UL data path is switched from the first node to the second node; and transmitting the UL data to the second node based on the second QoS flow to DRB mapping rule, after the UL data path is switched from the first node to the second node.

The embodiments in this invention extend distributed unit (DU), central unit (CU) and control plane of F1 (F1-C) capabilities so that differentiated DRBs of F1-U are placed on differentiated transport network components of equivalent QoS. This is achieved by a transport-aware DU and CU that can map each F1-U DRB into appropriate OSI layer 2-4 headers and can, subsequently, store such mappings. The F1-C interface is extended to distribute the layer 2-4 headers acquired from the transport network controller to the DUs and CU. A new control interface TN-C is defined between transport network controller and CU/DU. Furthermore, a trivial mapping of those embodiments is applicable for the N3 interface as well, which solves the same problem on the backhaul transport network.

Methods, systems, and devices for wireless communications are described that provide for timing synchronization among one or more time sensitive network (TSN) endpoints via a wireless communications network. A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.

Techniques described herein improve viewer experience by leveraging the ability of a viewer's device to access an over-the-top (OTT) content via the device's multi-channel connections to an OTT content server. In an example embodiment, the device receives the OTT content via a first channel and performs cross-party diagnostic testing through a second channel. In this embodiment, a diagnostic app in the device compares measured signals in the first channel with a first set of threshold values and further compares acquired telemetry data in the second channel with a second set of threshold values. Based on the comparison results, the device determines the possible root cause of the interruption. Further, the device performs an in-depth diagnostic testing on a determined possible root cause (e.g., OTT content server) and sends an in-depth diagnostic report to a viewer.

A communication control device included in a user plane of a mobile communication system in which a control plane and the user plane are separated includes: a packet transfer unit that transfers a packet to a network apparatus; a reception unit that receives, from the control plane, a basic DSCP being a DSCP set to each QoS flow by the control plane according to a QoS class; and a measurement unit that measures a use band amount of the packet for each of the QoS flow, and the packet transfer unit determines a new DSCP being a DSCP to be stored in the packet to be transferred, based on the basic DSCP and the use band amount of the QoS flow to which the packet to be transferred belongs, and stores the new DSCP in the packet to be transferred to the network apparatus.

A method of managing default QoS rules for PDU session is proposed. A PDU session defines the association between the UE and the data network that provides a PDU connectivity service. Each PDU session is identified by a PDU session ID, and may include multiple QoS flows and QoS rules. There can be more than one QoS rule associated with the same QoS flow. A default QoS rule is required to be sent to the UE for every PDU session establishment and it is associated with a QoS flow. Within a PDU session, there should be one and only one default QoS rule. In one novel aspect, UE behavior and error handling for proper QoS rule management is defined for PDU session establishment and modification procedures to enforce the one and only one default QoS rule policy.

Methods, systems, and devices are described for providing network access services to mobile users via multi-user network access terminals over a multi-beam satellite system. Quality-of-service (QoS) is controlled for the mobile devices at a per-user level according to user-specific traffic policies. Mobile users may be provisioned on the satellite system according to a set of traffic policies based on their service level agreement (SLA). System resources of the satellite may be allocated to mobile users based on the demand of each mobile user and the set of traffic polices associated with each mobile user, regardless of which multi-user network access terminal is used to access the system. Dynamic multiplexing of traffic from fixed terminals and mobile users on the same satellite beam can take advantage of statistical multiplexing of large numbers of users and on different usage patterns between fixed terminals and mobile users.

Systems, methods, and devices are disclosed for providing a quality of service between nodes. A service provider can receive, from a first node of a customer network to an ingress node of a service provider network, packets bound for a second node on the customer network that is remote from the first node. The packets are mapped to a network segment according to a traffic type based on an identifier associated with the packets that identifies the traffic type of the packets. The packets are sent via their mapped network segment to an egress node with connectivity to the second node of the customer network according to a quality of service associated with the traffic type identified by the identifier.

Mapping information of a bearer or quality of service can be communicated from a Wireless Local Area Network Termination (WT) to the enhanced Node B (eNB), which then uses radio resource control (RRC) signaling to communicate the mapping to the user equipment (UE). For example, three options can be used to communicate mapping information: (1) Operations and Management (OAM), (2) Semi-static Xw-AP signaling (e.g., WT Configuration Update or Xw Setup procedures) or (3) Dynamic Xw-AP procedures (e.g., WT Addition Request procedure). In some embodiments, the mapping can be signaled by (1) bearer to wireless local area networks (WLAN) access category (AC) mapping or (2) long term evolution (LTE) quality of service class identifier (QCI) to WLAN AC mapping.
