A method of handover in a mobile communication system comprises a first controller, e.g. a source base station subsystem (BSS) 3, setting a priority for each of two or more existing data flows from a mobile device 1 to a network 7. The multiple data flows may include both a circuit switched (CS) 5 data flow, such as a voice call, and a packet switched (PS) 6 data flow, such as a file download, which may occur in the dual transfer mode (DTM) of a GSM/EDGE radio access network (GERAN) 4. The first controller signals to a second controller the respective priorities for each data flow for which handover is requested. The first controller may indicate which of the existing data flows are critical so that, if the second controller can not allocate resources for all critical data flows, the handover is cancelled. |
