Aspects and embodiments provide: provides a base station method, a user equipment method, a base station and user equipment and computer program products operable to perform those methods. The base station method, comprises: when it is determined that a user equipment has been configured for dual connectivity with a master base station and a secondary base station, maintaining configuration information for a radio resource control connection with the secondary base station for utilisation in response to a change to the radio resource control connection with the secondary base station. Aspects recognise that if user equipment is operating in a dual connectivity network, it may be communicating with both a master and secondary eNB. As a result, information regarding the configuration of the user equipment may include information relating to radio bearers supported by the master eNB and the secondary eNB. Aspects also recognise that the handling of dual connectivity configuration information relating to the source eNB may not be supported by a target eNB and that the delta or full configuration options typically available within a network may not provide a suitable solution in relation to signalling support within a handover. |
