DETERMINING THE NEED FOR A ROUTING AREA UPDATE FOR PACKET SWITCHED HANDOVER IN MULTI-OPERATOR CORE NETWORK
First Claim
1. A method implemented by a controller functioning as 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 a packet switched (PS) domain to a target cell of a target RAN operating in the PS domain, the target RAN supporting multi-operator core network (MOCN), the method comprising:
- transmitting a system information 3 (SI3) message by the node to the MS, the SI3 message including a selected public land mobile network (PLMN) of the target cell; and
transmitting a PS handover command to the MS subsequent to transmitting the SI3 message.

Abstract
A method is implemented by a controller functioning as a node in a source Radio Access Network (RAN) to control handover of a mobile station (MS), where the handover of the MS is 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 supports multi-operator core network (MOCN). The method includes transmitting a system information 3 (SI3) message by the node to the MS, the SI3 message including a selected public land mobile network (PLMN) of the target cell, and transmitting a PS handover command to the MS subsequent to transmitting the SI3 message.

6. A method implemented by a mobile station (MS) for controlling handover of the MS from a source cell of a source Radio Access Network (RAN) operating in a packet switched (PS) domain to a target cell of a target RAN operating in the PS domain, the target cell supporting multi-operator core network (MOCN), the method comprising:
-
receiving a system information 3 (SI3) message transmitted by a node of the source RAN including a selected public land mobile network (PLMN) of the target cell; executing handover to the target RAN; determining a target routing area identity (RAI) using the selected PLMN from the SI3 message transmitted by the node of the source RAN; comparing the target routing area identity (RAI) to a registered RAI; and determining whether a routing area update (RAU) is needed in the target RAN based on a comparison of the target RAI to the registered RAI. - View Dependent Claims (7, 8, 9, 10)

11. A controller functioning as a node of a source radio access network (RAN) for controlling handover of a mobile station (MS) from a source cell of the source RAN operating in a packet switched (PS) domain to a target cell of a target RAN operating in the PS domain, the target RAN supporting multi-operator core network (MOCN), the controller comprising:
-
a non-transitory computer-readable medium having stored therein a RAN system information module and a RAN handover module; and a processor coupled to the non-transitory computer-readable medium, the processor to execute the RAN system information module and the RAN handover module, the RAN system information module to transmit a system information 3 (SI3) message to the MS, the SI3 message including a selected public land mobile network (PLMN) of the target cell, the RAN handover module to transmit a PS handover command to the MS. - View Dependent Claims (12, 13, 14, 15)

16. A mobile station (MS) configured for handover from a source cell of a source radio access network (RAN) operating in a packet switched (PS) domain to a target cell of a target RAN operating in the PS domain, the target RAN supporting multi-operator core network (MOCN), the MS comprising:
-
a non-transitory computer readable medium having stored therein a MS system information module, a MS handover module and a routing area update (RAU) module and a processor coupled to the non-transitory computer readable medium, the processor to execute the MS system information module, MS handover module, and RAU module, the MS system information module to receive a system information 3 (SI3) message transmitted by a node of the source RAN including a selected public land mobile network (PLMN) of the target cell, the MS handover module to execute handover to the target RAN, and the RAU module to determine a target routing area identity (RAI) using the selected PLMN of the target cell from the SI3 message transmitted by the node of the source RAN, the RAU module further to compare the target RAI to a registered RAI, and to determine whether a RAU is needed in the target RAN based on a comparison of the target RAI to the registered RAI. - View Dependent Claims (17, 18, 19, 20)
