Abstract: Provided are a UE migration method, apparatus and system and a storage medium. An NF that establishes a signaling interaction with an active SMF acquires a link state between the NF and the active SMF; the NF sends an SMF failure notification message to a standby SMF in response to determining that the active SMF fails; and the standby SMF migrates a UE to be migrated on the active SMF to the standby SMF according to a received SMF failure notification message. Further provided is a method for restoring UEs on a failed SMF to a standby SMF in batches.

Abstract: A method and device for adjusting radio resource are provided. The method comprises: an RAN acquires a radio resource using parameter of a terminal, wherein the radio resource using parameter of the terminal is used for indicating a frequency for receiving and sending data packets and/or a data packet transmission bandwidth when the terminal accesses network; the RAN adjusts a radio bearer resource occupied by the terminal according to the radio resource using parameter of the terminal, wherein an adjusted radio bearer resource is used by the terminal to transmit data. According to the disclosure, when a terminal accessing a 3GPP network frequently or occasionally send data packets, a network side optimizes to adjust the radio resource according to the acquired radio resource using parameter of the terminal. On the premise that user experience is not reduced, the network resource is optimized, achieving better network optimization and power saving effects.
