A method of effecting handover in a communications network of a first mobile station between a source and a target gateway is provided. The first mobile station engages in a call with a second mobile station using a destination gateway. The source gateway, the target gateway and the destination gateway are connected by a switched packet communication path for conveying call data packets. The method sends call data packets from the first mobile station to a source port at the destination gateway. The method opens a target port at the destination gateway for communication with the target gateway and routes call data packets from the first mobile station via the target gateway to the target port on the switched packet communication path. The method detects receipt of the call data packets at the target port and routes the call data packets from the second mobile station to the target gateway.
