METHOD AND APPARATUS FOR INFORM CHOSEN CORE NETWORK OPERATOR FROM UE TO RADIO ACCESS NETWORK IN A NETWORK SHARING SYSTEM

摘要

The present invention is directed to a method of notifying the CN operator terminal is selected on the network sharing (NS) system having a radio access network (RAN) is shared by a plurality of CN operators to RAN. After the initial direct transfer (IDT) transmission of the message the request for requesting a signaling connection, the terminal acquires a CN operator ID selected among CN operator identifier list to be broadcast in which the connection the radio resource control (RRC) cell, and wherein It transmits a CN operator identifier acquired by the RAN included in the IDT message. RAN is the context for the terminal, and stores the CN operator ID included in the IDT message. Since RAN selects a CN operator for the terminal using the CN operator identifier. ; Network Sharing, Initial Direct Transfer, SRNC relocation, chosen PLMN
