The application relates to a method for operating a flow control entity configured to control a data packet flow in a radio access network and a transport network of a communications network. It is determined that a transmission condition for the data packet flow through the communications network has changed, and determined through which radio access node the data packet flow is transmitted. A new anchor point for the data packet flow is determined in dependence on the radio access node, and a bearer control entity is informed about the new anchor point.

A wireless LAN access point is configured to perform a shaping operation to calculate and set an upper limit of communication speeds of belonging mobile units when the number of the belonging mobile units is equal to or more than a preset threshold. The wireless LAN access point is configured to extract a highest one or a lowest one of data transfer rates that are detected by analyzing header parts of communication packets to be exchanged respectively with the belonging mobile units as a shaping data-transfer rate. The wireless LAN access point is configured to calculate the upper limit of the communication speeds of the belonging mobile units on the basis of a correction factor that is arbitrarily set for converting the shaping data-transfer rate to an effective data-transfer rate, on the basis of the shaping data-transfer rate, and on the basis of the number of the belonging mobile units.

The present invention relates to a method and a device by which a UE configures a per access point name aggregate maximum bit rate (APN-AMBR) in a wireless communication system supporting coordinated selected IP traffic offload (CSIPTO). Particularly, the method comprises the steps of: configuring a plurality of PDN connections associated with different packet data network-gateways (P-GWs) for the same APN; respectively calculating APN-AMBRs of the plurality of PDN connections on the basis of the number of non-guaranteed bit rate (non-GBR) bearers for each of the plurality of PDN connections; and applying the APN-AMBRs to the respective, corresponding PDN connections.

Various examples and schemes pertaining to error handling on missing configuration for inter-system change in mobile communications are described. An apparatus performs a protocol data unit (PDU)-related procedure with a wireless network. The apparatus detects whether there is an error in the PDU-related procedure and the apparatus handles the error in response to detecting the error in the PDU-related procedure.

A method for guaranteeing data transmission and a communications device are provided. A method for guaranteeing data transmission applied to a first communications device includes: obtaining first information; and determining, based on the first information, a differentiated services code point DSCP corresponding to an Internet protocol security tunnel IPsec tunnel; where the first information includes at least one of the following: quality of service QoS information of a second network tunnel, data type information, a mapping relationship between differentiated service code points DSCPs and QoS information, a first QoS information requirement, and a first DSCP.

This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network controller of a wireless communication system may receive a time-sensitive network (TSN) traffic configuration that indicates a duration of a gate open state for a TSN traffic flow and a periodicity with which the gate open state occurs; configure one or more quality of service (QoS) parameters, associated with the wireless communication system, for a QoS flow that is to carry the TSN traffic flow, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters associated with the network controller and at least one of the duration of the gate open state or the periodicity; and transmit the one or more QoS parameters to a base station of the wireless communication system. Numerous other aspects are provided.

A system described herein may provide for the selection of a charging function (“CHF”) associated with a particular user equipment (“UE”). A particular CHF may be selected, from a group of candidate CHFs, based on CHF selection criteria respectively associated with the candidate CHFs and attribute information associated with the UE. The attribute information may describe attributes of the UE, profile information associated with the UE, and/or attributes of traffic and/or bearers associated with the UE.

Disclosed is an AMBR control method, device, and system, so that a quality of service (QoS) control mechanism can be used to control use of resources in a network slice by a terminal device. The method includes: a mobility management network element obtaining M pieces of single network slice selection assistance information (S-NSSAI) corresponding to a terminal device and a first slice-AMBR corresponding to each piece of S-NSSAI in the M pieces of S-NSSAI; and sending the M pieces of S-NSSAI and the first slice-AMBR corresponding to each piece of S-NSSAI to an access network device, where the first slice-AMBR corresponding to each piece of S-NSSAI is used to determine a second slice-AMBR corresponding to the S-NSSAI, and the second slice-AMBR corresponding to each piece of S-NSSAI is used to control an aggregate bit rate of non-guaranteed bit rate non-GBR QoS flows in a network slice indicated by the S-NSSAI.

A method and apparatus for service data adaptation protocol (SDAP) reconfiguration based on state transition in sidelink communication is provided. A first wireless device receives, from a network in a connected state, information on quality of service (QoS) flow to data radio bearer (DRB) mapping, and upon leaving the connected state, keeps using the QoS flow to DRB mapping for a time duration until a new QoS flow to DRB mapping is used.
