The method (200) performed by a first network node (1100, 1200) capable of an Ethernet bridging function includes: obtaining (S201) information on frame detection and forwarding rules for an Ethernet PDU session; and performing (S203) detection and forwarding operations on a frame according to the frame detection and forwarding rules.

Abstract: Methods and apparatuses for control of virtual local area network (VLAN) are disclosed. 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.

Abstract: Methods and apparatuses for a 5G System (5GS) (20) support dynamic and semi-dynamic VLAN configuration for Ethernet bridging services provided by the 5GS. The 5GS (20) includes a node that is configured to receive and store VLAN configuration information for a CE (12). Particularly, the VLAN configuration information, which comprises a single predefined VLAN ID (VID) or a list of non-predefined VIDs or a single non-predefined VID, may be stored advantageously within 5G Virtual Network (VN) Group Data and indicates whether the UE (12) acts as an Ethernet trunk port or access port. With respect to the 5GS (20) establishing or modifying an Ethernet PDU session for the UE (12), a UPF (22) of the 5GS (20) configures Ethernet bridging operations for the UE as an access port or a trunk port, in dependence on the VLAN configuration information.

Abstract: 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 VLAN's 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.

Abstract: An access node of the cellular network determines a correlation of an identifier of a user equipment with an entry of a Pending Interest Table maintained by an Information Centric Networking node. The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request at the Information Centric Networking node. Based on the correlation, the access node controls a connection of the user equipment with the cellular network. This may involve deciding whether to release the user equipment to idle mode or paging of the user equipment.

Abstract: A method and a device proxy for handling radio communication of content data from a data source to be played out on a media player of a wireless device in a wireless network. When detecting that a potential data class is available, the device proxy 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 in an intermediate buffer, and the segments of content data are delivered from the intermediate buffer when requested by the media player.

Abstract: An access node (20) of a cellular network receives an information centric networking request of a user equipment (10) for a data object. The access node forwards the information centric networking request to a local gateway (30) associated with the access node (20). The local gateway (30) maintains a pending interest table including an entry for each data object having a pending information centric networking request at the local gateway (30). In response to the user equipment (10) moving from a coverage area of the access node (20) to a coverage area of a further access node (21), the access node (20) and the further access node (21) perform a handover procedure. The further access node (21) is associated with a further local gateway (31) maintaining a further pending interest table. The further pending interest table includes an entry for each data object having a pending information centric networking request at the further local gateway (31).
