METHOD AND SYSTEM FOR MANAGING SECURITY IN MOBILE COMMUNICATION SYSTEM |
摘要 |
A method, an apparatus, and a system for solving and managing security problems, which may occur during a handover of a User Equipment (UE) between PLMNs in a mobile communication network, by using a Non-Access Stratum (NAS) protocol are provided. By the method, a UE can perform a security mode command and an authentication with a network. Further, the method can prevent interruption of communication due to authentication or security during a handover of a UE between Public Land Mobile Networks (PLMNs). |

1. A method for performing a security procedure by a mobility management entity (MME) in a mobile communication system, the method comprising:
receiving, from a terminal, a tracking area update (TAU) request message including a public land mobile network identity (PLMN ID) after a handover of the terminal; comparing the PLMN ID included in the TAU request message with a PLMN ID of a cell; transmitting, to the terminal, an authentication request message if the PLMN ID included in the TAU request message is different from the PLMN ID of the cell and a TAU procedure is complete; and receiving, from the terminal, an authentication response message if an authentication is verified, wherein the authentication response message includes a response parameter (RES). |
