CONTROLLING HANDOVER OF A MOBILE STATION FROM E-UTRAN/GERAN CIRCUIT SWITCHED IN A MULTI-OPERATOR CORE NETWORK

摘要

A method by a target U T RAN or target GERAN operating in CS domain to control handover of a MS from a source RAN. The method includes receiving a handover request message from a M SG server as a result of handover triggered by the source RAN. The handover request message identifies a selected PLMN identity (ID) that will serve the MS after handover. A corresponding PLMN ID index is generated that indicates an association between the selected PLMN I D and one of a plurality of PLMN I Ds of a set transmitted as system information on a Broadcast Control Channel (BCCH) by the target UTRAN or target GERAN. A handover response containing the PLMN ID index is communicated toward the MSG server for subsequent forwarding to the MS by the source RAN. Related mobile stations and methods are disclosed.
