摘要:
Methods and apparatuses for a 5G System (5GS) (20) support Dynamic VLAN configuration for a logical Ethernet bridge (24) provided by the 5GS. In at least one embodiment, a User Plane Function (UPF) (22) runs, on a conditional basis, for example, Multiple VLAN Registration Protocol (MVRP) for a User Equipment (UE) (12) establishing or modifying an Ethernet Protocol Data Unit (PDU) session. Running MVRP allows the UPF to learn the VLANs associated with the UE and correspondingly dynamically configure bridging services. In one or more embodiments, UEs that act as trunk ports are assigned a predefined VLAN ID, e.g., via an Application Function (AF) (32), and, for a UE establishing or modifying a session, a Session Management Function (SMF) (26) indicates the predefined VLAN ID to the UPF, triggering the UPF to run MVRP for the UE.

Methods and device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) for managing Round Trip Time, RTT, associated with provision of a data flow (150; 250) from a server device (130; 230), via a multi-access communication network (100; 200), to a client device (120; 220). Said device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) being communicatively connected to the multi-access communication network (100; 200) that is configured to provide the data flow (150; 250) to the client device (120; 220) using a resource of the multi-access communication network (100; 200) that is shared by multiple devices (120-121; 220-221). The device(s) (110; 120; 130; 140; 141; 210; 212; 220; 230; 600) initiates, in response to identification that the data flow (150; 250) belongs to a certain type, introduction of an artificial delay in the RTT.

Methods and apparatus described by way of example in this document select between different versions of a content stream, e.g., on a per segment basis, for wireless delivery to a client device. Advantageously, both versions have the same representation level but have different transmission bandwidth requirements. As an example, the representation level is a video resolution and one version of the content stream has higher video quality at the defined resolution but generally requires more transmission bandwidth than the other version. A control node having access to both versions dynamically selects which version to send for delivery to a client device via a Radio Access Network (RAN) supporting wireless delivery to the client device, in dependence on monitoring RAN performance. Among other things, dynamic version selection on the network side reduces the need for the client device to reselect to a lower representation level responsive to decreases in the available transmission bandwidth in the RAN.

Embodiments described herein provide methods and apparatus for transmitting traffic using a first communications technology and a second communications technology to a 5 communications network. The method comprises providing a first virtual link configured to receive first traffic from a first end device, wherein the first virtual link has a plurality of first link characteristics; providing a second virtual link configured to receive second traffic from the first end device, wherein the second virtual link has a plurality of second link characteristics; transmitting the first traffic to a communications network over a first 0 network link using the first communications technology; and transmitting the second traffic to the communications network over a second network link using the second communications technology.
摘要:
A method and a device proxy (206) for handling radio communication of content data from a data source (204) to be played out on a media player (208) of a wireless device (200) in a wireless network. When detecting that a potential data class is available, the device proxy (206) fetches segments of the content data from the data source over a potential data bearer dedicated for data of said potential data class. The potential data bearer is dedicated for data of the potential data class, which is less sensitive to delay than data of other data classes. The potential data bearer is also less costly to use compared to other data bearer(s). The fetched segments of content data are stored by the device proxy (206) in an intermediate buffer (206A), and the segments of content data are delivered from the intermediate buffer when requested by the media player (208).
摘要:
An access node (620) of the cellular network determines a correlation of an identifier of a user equipment (610) with an entry of a Pending Interest Table maintained by an Information Centric Networking node (670). The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request (801) at the Information Centric Networking node (670). Based on the correlation, the access node (620) controls a connection of the user equipment (610) with the cellular network. This may involve deciding whether to release the user equipment (610) to idle mode or paging of the user equipment (610).

The invention relates to wireless communication device and a method performed at the wireless communication device of requesting Information Centric Networking (ICN) content, a network node, and a method performed at the network nodeof scheduling delivery of ICN content to at least one wireless communication device. In an aspect, a method performed at a network node(102) of scheduling delivery of ICN content to at least one wireless communication device (103) is provided. The method comprises receiving (S101a) a request for the ICN content from the at least one wireless communication device (103), deriving (S102), from the received request, content description data specifying at least one property of the ICNcontent being requested, and scheduling (S103) delivery of the requested ICN content to the at least one wireless communication device (103) on the basis of the derived at least one property of the requested ICN content.

The invention relates to a User Equipment (UE) and a method performed at the UE of acquiring content, a Radio Base Station (RBS), and a method performed at the RBS of supplying Information Centric Networking (ICN) content to at least one UE. In a first aspect of the invention a method performed at a UE (103) of acquiring content is provided. The method comprises submitting a request for content to an RBS (102), receiving, in reply to the request, the requested content from the RBS, the content being acquired by the RBS from an ICN node (109) and provided to the UE (103) from the RBS (102) upon the RBS receiving the ICN content, storing the received ICN content in a local storage (123) at the UE (103), and acquiring, when a piece of content is to be rendered at the UE (103), the piece of content from the received ICN content in the local storage (123).

According to an embodiment, a service consumer sends, to a service provider of a Fifth Generation System (5GS) that provides Ethernet bridging operations for User Equipments (UEs) acting as Ethernet access ports or Ethernet trunk ports, a request for providing configuration information related to a VLAN. The configuration information indicates a port type of at least one port related to the VLAN.

A method of operating a UPF in a wireless communication system includes receiving a data packet, identifying a PFCP session context associated with the data packet, determining whether a PDR associated with the PFCP session context should be modified or a new PDR should be created, transmitting a request to a session management function to provision a new or modified PDR at the UPF, receiving a session modification response from the SMF provisioning the new or modified PDR for the PFCP session context at the UPF, and applying the new or modified PDR on the data packet.
