An arrangement and method for carrying out a handover between first and second base station controllers in a telecommunications system that includes a local exchange of a fixed network; mobile stations; base station systems providing the mobile stations with a wireless access network to the local exchange, each base station system having a base station controller and a plurality of base stations; transmission circuits for connecting the local exchange to the base station controllers; the control of the handover between the base station controllers being located in the base station controllers so that the first base station controller of the call functions as the anchor point at which the original connection established via the local exchange is maintained, and from which a further connection is established to a second base station controller in a handover. The base station controllers are arranged to maintain the local call connection between base station controllers at the end of the call, and keep it in reserve for the following handover between base station controllers, and the first or second base station controller is arranged to make the decision on using the reserved local call connection as a further connection in a new handover between base station controllers and to communicate the decision to the other one of the base station controllers.
