<p>The invention relates to a method and an arrangement for performing a handover between base station controllers in a telecommunications system, the base station systems (BSC, BTS) providing mobile stations (PS) with a wireless access network to the local exchange (LE) of a fixed network. The control of the handover between the base station controllers (BSC) is located in the BSC's so that the first BSC of the call operates as the anchor point at which the initial connection established via the local exchange is maintained, and from which a further connection is established to a second BSC in a handover situation. The base station controllers do not release the local call connection between the base station controllers at the end of the call, if necessary, and keep it in reserve for the following handover between base station controllers. The base station controllers may also establish a new local call connection between the base station controllers and keep it in reserve for the following handover. Thus, the signalling load may be reduced since the connection resources to the local exchange are not reserved and released every time that new handovers take place.</p> |
