Abstract

Embodiments herein relate to a method in a radio base station for enabling a user equipment to establish a connection in a radio communications network The user equipment is served in a first cell controlled by the radio base station. The radio base station is comprised in the radio communications network. The radio base station detects a failure of a radio link between the user equipment and the radio base station. The radio base station then forwards a user equipment context of the user equipment to a circuitry controlling a second cell when the failure is detected. The user equipment context enables the circuitry controlling the second cell to serve the user equipment and thereby enables the user equipment to establish the connection in the radio communications network.
