This abstract first appeared for US patent application 20250150946 titled 'METHOD AND APPARATUS FOR PROCESSING IN OPERATOR NETWORK BY DETECTING ABNORMAL BEHAVIOR OF UE
Original Abstract Submitted
the present disclosure relates to: a 5g communication technique for supporting a higher data transmission rate than a 4g system; and a system therefor. the present disclosure relates to a method by which, when ue accesses a network, an access management function (amf) verifies whether or not the access is duplicated access from the ue to determine whether or not to allow the ue to access the network, and comprises the steps of: before the amf allows corresponding ue to access the network, the amf combining a newly accessing ue id and auxiliary indicators to determine whether or not it is duplicated access from the ue; on the basis of the result of the determination, transmitting paging to a location that has been previously accessed from the ue; determining a response value of the ue to the transmission of paging, and the amf/nwdaf determining whether or not the newly accessing ue id is duplicated; when a duplicated ue id value is derived, controlling access from the corresponding ue and ue that has accessed a previous location, via whether or not new access or existing access applied to a pcf has been allowed.
