There are provided measures for control of data rate boosts in radio access networks. Such measures exemplarily comprise, at an access node in a mobile network, receiving (S), from a core network entity in said mobile network, an indication in relation to a data rate boost with respect to an uplink flow of a terminal, and preparing (S) said data rate boost based on said indication.

Control of data rate boosts in radio access networks

There is provided an apparatus, said apparatus comprising means for receiving, from a session management node, burst timing information for a 5G ingress node, receiving burst timing adjustment capability information for an application from a function associated with the application, determining at least one of preferred burst arrival times and periodicity at the 5G ingress node for at least one periodic traffic stream from the application based on the burst timing information and burst timing adjustment capability information and providing an indication of the at least one of determined preferred burst arrival times and periodicity to the function.

Apparatus, method and computer program

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.

Transferring traffic in integrated access and backhaul communication

It is provided a method, comprising monitoring if an assignment packet is received by a new node from a parent node; setting, if the assignment packet is received, a new value of an identifier for determining if a first packet of a first layer protocol is intended for the new node; wherein the assignment packet comprises the new value of the identifier; the assignment packet is a packet of the first layer protocol; the assignment packet comprises a header of the first layer protocol.

Address assignment

Embodiments of the present disclosure relate to for inter-CU topology adaptation. A first device establishes a communication interface between the first device and a second device. The first device receives from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed. The first device transmits to the second device a command indicating the second device to activate cells configured by the first device.

Device, method, apparatus and computer readable medium for inter-CU topology adaptation

Various communication systems may benefit from differentiated quality of service management. For example, specific applications run on a user equipment in a 5G radio access network may benefit from the flexible differentiated quality of service management. A method includes determining a service flow setup, and mapping traffic through the service flow by a common convergence sublayer entity to at least one radio convergence sublayer entity. The method also includes controlling the traffic through the service flow.

Flexible mapping of logical end-points

There is provided a method at a first network node, comprising: receiving, from a second network node, a message comprising a requested quality of service (QoS) profile and one or more alternative QoS profiles, wherein the QoS profiles are associated with a communication with a user equipment; determining that the requested QoS profile cannot be provided by the first network node for a communication between the first network node and the user equipment; determining that at least one of the one or more alternative QoS profiles can be provided by the first network node for a communication between the first network node and the user equipment; transmitting, to the second network node, an indication that an alternative QoS profile can be provided by the first network node; and, transmitting, to the second network node, an indication for configuring the user equipment based on the requested QoS profile.

Communication efficiency

An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive () a request to create context for a migrating node and optionally at least one child node of the migrating node; allocate () addresses to the migrating node and optionally the at least one child node of the migrating node; and send () the addresses allocated to the migrating node and optionally the at least one child node of the migrating node, prior to the migrating node migrating from a source to a target.

Apparatus, method, and computer program

Systems, methods, apparatuses, and computer program products relating to packet data unit (PDU) session, for example, in 5G or new radio access technology (NR). One method may include receiving a configuration for how to handle flows to two network nodes for transmission. The method may include directing the flows of an incoming PDU session to two network nodes for the transmission.

Protocol data unit session splitting function and signaling

Various communication systems may benefit from improved quality of service flow. A method may include receiving an indication at a radio resource control entity or service data adaptation protocol layer entity in a radio protocol of a receiver from a transmitter. The indication can include instructions to relocate a quality of service flow from a source to a target data radio bearer. The method may also include starting a timer associated with the quality of service. In addition, the method may include buffering data packets received as part of the quality of service flow from the target data radio bearer during a duration of the timer. Further, the method may include allowing for the transmission of the buffered data packets of the quality of service flow received from the target data radio bearer to an upper protocol layer after the duration of the timer has lapsed or stopped.

Quality of service flow relocation

There are provided measures for assisted distributed gateway selection. Such measures exemplarily comprise (as control plane network entity functionality in a mobile network scenario where an access of a terminal to a network is movable between at least two base stations and routable in parallel via at least one local gateway and a centralized gateway) detecting movement of said access of said terminal from a first base station to a second base station, determining that a first network route which is a current network route from said terminal via a first local gateway which is a current local gateway of said at least one local gateway provides less network performance than a second network route from said terminal via a second local gateway of said at least one local gateway based on a result of said detecting, and deciding said second local gateway as a target local gateway for said terminal based on a result of said determining.

Assisted distributed gateway selection

Methods and apparatus, including computer program products, are provided for QoE/QoS management. In some example embodiments, there may be provided a method. The method may include detecting, by an enforcement point, an initiation of a session of an application; determining, by the enforcement point, whether a new subservice flow needs to be established to enable, for the initiated session, a quality of service differentiation and/or a quality of experience differentiation; sending, by the enforcement point, an indication to a radio to enable the radio to establish a radio buffer to handle the new subservice flow, when the new subservice flow needs to be established; sending, by the enforcement point, parameter information to the radio to enable the radio to configure at least one service parameter of the radio buffer; and forwarding, by the enforcement point, user-plane data associated with the session to the radio including a subservice flow identifier. Related apparatus, systems, methods, and articles are also described.

QoS/QoE enforcement driven sub-service flow management in 5G system

A technique of performing a handover within a 5G network include at least one of the following approaches. In one approach, a source gNB resets any mapping indicators from the forwarded SDAP PDUs, i.e., forwarded downlink data packets. Accordingly, subsequent uplink data packets will not be mapped according to the mapping tables of the source gNB. In another approach, the UE is configured to ignore mapping indicators of the forwarded downlink data packets. That is, in response to receiving a handover command message from the source gNB, the UE does not respond to updates of mapping tables from the source gNB. Again, subsequent uplink data packets will not be mapped according to the mapping tables of the source gNB.

Uplink bearer binding in handover

Improving user experience during handover. Transmitting by a source base station to a target base station a handover request message including a range of QoS profiles, receiving by the source bases station from the target base station a handover request acknowledge message indicating the radio resources or QoS profile selected from the range of QoS profiles, transmitting by the source base station station an identified resource gap between the selected QoS profile of the target base station and the currently used QoS profile in the source base station to an experience management entity.
