Method and apparatus for informing a radio access network of a selected core network from user equipment in a network sharing system
First Claim
1. A method of informing a radio access network (RAN) of a selected core network (CN) operator in a user equipment (UE) in a network sharing (NS) system where a plurality of CN operators share the RAN, the method comprising the steps of:
- generating an initial direct transfer (IDT) message to request a signaling connection;
acquiring a CN operator identifier (ID) selected among CN operator IDs in a multi-ID list broadcasted from a cell in which a radio resource control (RRC) connection has been established; and
inserting the selected CN operator ID in the IDT message and transmitting the IDT message to the RAN.

Abstract
A method of informing a selected CN operator from a UE to a RAN in an NS system where a plurality of CN operators shares the RAN is provided. Upon request of transmission of an IDT, the UE acquires a CN operator ID selected from a multi-ID list broadcasted from a cell in which an RRC connection has been established, and transmits an IDT message with the selected CN operator ID to the RAN. Upon receipt of the IDT message, the RAN determines whether the IDT message includes a selected CN operator ID. In the presence of the selected CN operator ID, the RAN stores the selected CN operator ID in a UE context. In the absence of the selected CN operator ID, the RAN reads a stored selected CN operator ID from the UE context. The RAN then selects a CN operator using the selected CN operator ID.

11. An apparatus for informing a radio access network (RAN) of a core network (CN) operator selected by a user equipment (UE) in a network sharing (NS) system where a plurality of CN operators share the RAN, the apparatus comprising:
-
a controller for generating an initial direct transfer (IDT) message for requesting a signaling connection and inserting in the IDT message a CN operator identifier (ID) selected among CN operator IDs in a multi-ID list broadcast from a cell with which the UE has established a radio resource control (RRC) connection; and
a transmitter and receiver for transmitting the IDT message to the RAN. - View Dependent Claims (12, 13, 14, 15, 16)

17. An apparatus that is informed of a core network (CN) operator selected by a user equipment (UE) in a radio access network (RAN) in a network sharing (NS) system where a plurality of CN operators share the RAN, the apparatus comprising:
-
a receiver for receiving an initial direct transfer (IDT) message for requesting a signaling connection from the UE;
a controller for acquiring a selected CN operator ID from the IDT message, choosing a CN operator using the selected CN operator ID, and controlling connection between the UE and the CN operator corresponding to the CN operator ID;
a memory for storing the selected CN operator ID; and
a transmitter for communicating with the UE and the CN operator. - View Dependent Claims (18, 19, 20)
