    摘要: Systems and methods are disclosed herein that relate to a cellular communications system that operates as a virtual Ethernet bridge(s). Embodiments of a User Equipment (UE) for a cellular communications system and corresponding methods of operation of a UE are disclosed. In some embodiments, a UE for a cellular communications system, where the cellular communications system operates as multiple Ethernet network virtual bridges, comprises one or more transmitters, one or more receivers, and processing circuitry associated with the one or more transmitters and one or more receivers. The processing circuitry is configured to cause the UE to establish a first Protocol Data Unit (PDU) session to an Ethernet network via a first User Plane Function (UPF), wherein PDU sessions that connect to the Ethernet network via the first UPF are grouped into a first Ethernet network virtual bridge. In this manner, shared media in the Ethernet network can be avoided.

    摘要: The inventing refers to a method of performing a synchronization communication between a master clock (100) and a slave clock (130), wherein the communication involves wireless network comprising a base station or eNB (110) and a wireless terminal or UE (120), wherein the base station (110, 110′) performs the steps of: receiving (S01) from the master clock (100) a synchronization packet (M11, M21) comprising a time information relative to the master clock (100), obtaining (S03) a first delay time accounting for an actual scheduling delay with respect to the UE (120), generating (S04) a modified synchronization packet (M12, M22) by modifying the time information to take into account the first delay time, and transmitting (S05) the modified synchronization packet (M12, M22) to the UE (120) to be forwarded to the slave clock (130). The invention further refers to a corresponding eNB (110, 110′), a method performed by the UE (120), to a corresponding UE (120) and corresponding software programs.

    摘要: The disclosure relates to a method for a first network entity of handling control plane context information relating to wireless devices. The first network entity is configured with a first context replication domain. The method comprises handling control plane context information relating to one or more wireless devices, and communicating, with each additional network entity also configured with the first context replication domain, changes of control plane context information for the one or more wireless devices. The disclosure also relates to corresponding computer program, computer program product and first network entity.

    摘要: A method performed by a network node of a communications network for enabling internet protocol, IP, based deterministic networking. The method comprises receiving a routing request from a software-defined networking (SDN) controller, particularly wherein the SDN controller is associated with a deterministic network (DetNet); determining whether the routing request conflicts with the routing of the communications network; and responsive to determining whether the routing request conflicts with the routing of the communications network, transmitting a response to the SDN controller indicating acceptance or denial of the routing request. The network node may be a Deterministic Networking Application Function (DetNet AF).

    摘要: Systems and methods are disclosed herein that relate to actions performed by a Radio Access Network (RAN) when redundancy is not available. In this regard, embodiments of a method performed by a RAN node are disclosed. In one embodiment, a method performed by a RAN node for RAN action when redundancy is not available comprises receiving, from a core network node, a request for a set of User Plane (UP) resources in the RAN. The method further comprises determining whether the request for the set of UP resources in the RAN can be met and sending, to the core network node, a response to the request for the set of UP resources that is based on whether the request for the set of UP resources in the RAN can be met.
