1. A method implemented by a node in a source Radio Access Network (RAN) to control handover of a mobile station (MS) from a source cell of the source RAN operating in packet switched (PS) domain to a target cell of a target RAN operating in PS domain, the target RAN supporting multi-operator core network (MOCN), the method comprising the steps of:

  • transmitting system information about the target cell for handover by the node to the MS, the system information including a selected public land mobile network (PLMN), location area code (LAC) of the target cell, and routing area code (RAC) of the target cell; and

    sending a PS handover command to the MS,wherein the selected PLMN and the LAC of the target cell is transmitted in a system information 3 (SI3) message sent on a Packet Associated Control Channel (PACCH).
