ABSTRACT:
A packet-switched handover from a first cell to a second cell in a cellular network is discussed. Packet-switched services are provided for a mobile station in the first cell based on a set of information relating to provision of packet-switched services and a protocol for handling provision of packet-switched services for mobile stations, said protocol being a protocol between a cell and a respective control network element. In a control network element relating to the first cell a first message is received, which indicates a request for a packet-switched handover for a mobile station. In response to said first message, a second message is sent to the second cell. This second message requests creation of a set of information relating to provision of packet-switched services for the mobile station in the second cell, and the second message belongs to said protocol for handling provision of packet-switched services for mobile stations.
