<p>A method of effecting handover in a communications network of a first mobile station between a source gateway and a target gateway, the first mobile station being engaged in a call with a second station using a destination gateway wherein 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 comprising: i) opening a target port at the destination gateway for communication with the target gateway; ii) routing call data packets from the first mobile station via the target gateway to the target port on the switched packet communication path; iii) detecting receipt of said call data packets at the target port; and then, responsive to such detection, iv) routing call data packets from the second station via the destination gateway to the target gateway on the switched packet communication path. <IMAGE> <IMAGE> <IMAGE> <IMAGE></p> |
