Abstract
A method for performing communication in a wireless communication system in includes establishing, by a network entity, a context of a user equipment (UE) in a network, receiving a message for registration request from the UE in a registered state, identifying that the UE is genuine by executing an authentication procedure with the UE, and in case that the UE is genuine, performing a deletion of the established context of the UE and a process of the registration request.
Claims8
A method for a network entity performing communication in a wireless communication system, the method comprising:
- establishing a context of a genuine user equipment (UE) in a network;
- receiving, from a UE, a message for a second registration request while the genuine UE is in a first registered state;
- upon reception of the message for the second registration request from the UE, determining whether the UE is the genuine UE or not by executing an authentication procedure with the UE;
- in response to determining that the UE is the genuine UE by the authentication procedure, deleting the established context of the genuine UE for the first registered state, and establishing a new context of the genuine UE;
- and
- in response to determining that the UE is not the genuine UE by the authentication procedure, maintaining the established context of the genuine UE for the first registered state.
A network entity for performing communication in a wireless communication system, the network entity comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to:
- establish a context of a genuine user equipment (UE) in a network;
- receive, from a UE, via the transceiver, a message for a second registration request while the genuine UE is in a first registered state on the network;
- upon reception of the message for the second registration request from the UE, determine whether the UE is the genuine UE or not by executing an authentication procedure with the UE;
- in response to determining that the UE is the genuine UE by the authentication procedure, delete the established context of the genuine UE for the first registered state, and establish a new context of the genuine UE;
- and
- in response to determining that the UE is not the genuine UE by the authentication procedure, maintain the established context of the genuine UE for the first registered state.
