A METHOD OF SECURING WIRELESS BACKHAUL, A CHILD BASE STATION, A PARENT BASE STATION AND METHODS IN THE CHILD AND PARENT BASE STATIONS

摘要

A method of securing wireless backhaul for a child base station in a first network provided by a first operator, wherein:any parent base station with wireline backhaul capability and configured to virtualise a core network User Plane Function, UPF, advertises that it supports a wireless backhaul service;the child base station in the first network connects over an air interface to one or more parent base stations in a second network provided by a second operator;the child base station sends a backhaul service request to a connected parent base station;when the backhaul service request is accepted, the connected parent base station uses a virtualised UPF to enable a direct wireline backhaul link between the parent base station and a data network; and the child base station uses the air interface as a wireless backhaul link and the wireline backhaul link of the connected parent base station for backhaul.
