description In one embodiment, a method implemented in a virtual network function (VNF) manager (230) for delivering of services to a roaming UE (200) is disclosed. The method includes identifying (1710) a trigger condition for handing-over delivery of at least a subset of services from a radio interface of a source radio base station (210) to a radio interface of a target radio base station (220). The method also includes transferring the subset of the services to the target radio base station (220) through a route based on information from a software-defined networking (SDN) controller (1250) of a SDN system that includes the source radio base station (210) and the target radio base station (220). The method further includes causing at least one VNF (250, 255) to be deployed on the target radio base station (220), the at least one VNF (250, 255) on the target radio base station (220) being adapted to offer the subset of the services to the roaming UE (200).
