Information-centric networking over 5G or later networks
In a communication network, a network function may be provided for controlling Information Centric Networking (ICN) protocol-based traffic flow between a set of user equipment (UE). This network function may be an ICN application function (ICN-AF), and may obtain ICN layer information from an ICN router which is indicative of a congestion state of a current PDU session of user equipment. If the congestion state indicates congestion, the ICN-AF may initiate establishment of a new PDU session for the user equipment (UE1) or initiate upgrade of a quality of service (QoS) characteristic of the current PDU session, for example using the session management function (SMF) and via the SMF's session management of PDU sessions.
USER-PLANE CONGESTION MANAGEMENT
Methods, apparatuses and systems for user-plane congestion management are provided. Among these method, apparatuses and systems is a method, implementable by a base station (and/or a serving gateway), for mitigating user plane congestion. The method may include sending a congestion indication to a core network; receiving a general packet radio system (GPRS) tunneling protocol (GTP) packet including an first internet protocol (IP) packet associated with a first flow within a bearer; obtaining, from a header of the GTP packet, an indicator indicative of a priority of the IP packet, wherein the indicator was inserted into the header of the GTP packet by the core network responsive to the congestion indication; and dropping any of the GTP packet and the first IP packet on condition that a priority of a second IP packet associated with second flow within the bearer takes precedence over the priority of the first IP packet.
Enhanced traffic capacity in a cell
Various communication systems may benefit from enhanced cell capacity. For example, certain embodiments may benefit from improved packet capacity by managing transmissions in a cell. A method, in certain embodiments, may include determining at a network node whether a packet is of a service type. The service type may indicate that the packet is discardable. The method may also include calculating at the network node a probability factor or a scheduling adjustment factor for transmission of the packet, when it is determined that the packet is of the service type. In addition, the method may include determining at the network node whether to transmit the packet to a user equipment based on the probability factor, or adjusting at the network node a scheduler metric based on the scheduling adjustment factor.

TRAFFIC MANAGEMENT TECHNIQUE FOR VARIABLE BANDWIDTH NETWORKS USING RSVP
An example system comprises a router configured to receive a bandwidth update associated with a change in bandwidth over a wireless channel, determine if the change in bandwidth identified in the bandwidth update results in bandwidth being over-reserved at at least one priority level, previously reserved bandwidth of the wireless channel being associated with a plurality of different priority levels, the previously reserved bandwidth being previously reserved based on a plurality of path requests from a head end router, each path request including at least one priority level and a bandwidth reservation request, if the change in bandwidth results in bandwidth being over-reserved, then preempt a lowest priority path request, based in the preemption of the lowest priority path request, update reserved bandwidth of the wireless channel of at least one priority level, and provide a message to the head end router regarding the change of bandwidth.
ELECTRONIC DEVICE, WIRELESS COMMUNICATION METHOD, AND COMPUTER READABLE MEDIUM
The present disclosure relates to an electronic device, a wireless communication method, and a computer readable medium. According to an embodiment, an electronic device for user equipment side comprises a processing circuit. The processing circuit is configured to: for a first communication resource allocated by a base station to a cellular link and a second communication resource allocated to a pass-through link, allocate resources to the cellular link and the pass-through link in a manner of sharing the first communication resource and the second communication resource; and carry out control to communicate data on the basis of the resource allocation.
COMMUNICATION METHOD AND APPARATUS
This application provides a communication method and an apparatus. UE establishes a connection to a home access gateway by using CPE, the home access gateway sends configuration information of a first link and configuration information of a second link to the CPE, and sends the configuration information of the second link to the UE. The first link is a link between the CPE and the home access gateway, the second link is a link between the CPE and the UE, the configuration information of the first link is used to indicate quality of service QoS information of the first link, and the configuration information of the second link is used to indicate QoS information of the second link. The UE and the CPE ensure, based on respective configuration information, QoS of UE service data transmitted on the first link and the second link.
Data processing method and apparatus
Embodiments of this application provide a data processing method and apparatus. The method includes: parsing, by a user plane data processing network element, a received packet and determining first service type information of a data flow to which the packet belongs; obtaining, by the user plane data processing network element, second service type information of the data flow from a data analysis network element; and processing, by the user plane data processing network element, the data flow based on the first service type information and the second service type information. With the data processing method and apparatus disclosed herein, accuracy in identifying a service type of transmitted data can be improved.
Quality of service realization in multi-hop data forwarding
Logical Channel Prioritization (LCP) may be enhanced by accounting for Quality of Service (QoS) attributes of single hop and multi-hop paths. QoS attributes may be communicated as a QoS budget comprising a number of attributes, or as a single composite QoS “resistance” factor that quantifies the compounded impact of number of hops, latency, load conditions, and the like. The QoS budget or resistance may dynamically adjusted, and may be used by LCP to provide differentiated uplink resource allocation to data of the bearer or logical channel subject to different transmission paths between the transmitter and the receiver, for example. QoS budget and resistance information may be used to, e.g., enhance Buffer Status Report (BSR) and Scheduling Request (SR) operations.
Repetition-based transmission
Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement transmission repetitions for transport blocks (TBs) to improve reception reliability. However, to support low latency, TBs may be transmitted in any transmission time interval (TTI) within a subframe. The systems may implement process to handle these TB repetitions. In some cases, a device may receive, during a TTI of a subframe, control information including an indication of transmission repetitions of a TB for a plurality of TTIs, identify a quantity of transmission repetitions of the TB based on the control information, and monitor for the transmission repetitions of the TB.
