INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for Power Saving Mode (PSM) operation control of a UE in a mobile communication system is provided. The method includes: setting a PSM for the UE; triggering a connection request of the UE in the PSM; determining whether the connection request has been barred; and maintaining the PSM setting when it is determined that the connection request has been barred. ## Claims ### Claim 1 A method for Power Saving Mode (PSM) operation control of a UE in a mobile communication system, comprising: setting a PSM for the UE; triggering a connection request of the UE in the PSM; determining whether the connection request has been barred; deactivating the PSM and changing to an active mode, when it is determined that the connection request has not been barred; and maintaining the PSM setting without changing to an idle mode, when it is determined that the connection request has been barred. ### Claim 2 (depends on 1) The method of claim 1, wherein the maintaining of the PSM setting comprises: maintaining the PSM setting until the expiration of a timer that bars a Radio Resource Control (RRC) connection setting for at least the connection request. ### Claim 3 (depends on 1) The method of claim 1, wherein the connection request comprises at least one of: a call, signaling, or a Circuit Switched (CS) fallback, which are generated from the UE. ### Claim 4 (depends on 1) The method of claim 1, wherein an operation corresponding to the connection request is barred for a time interval during which the PSM setting is maintained. ### Claim 5 (depends on 1) The method of claim 1, further comprising: before the setting of the PSM, determining whether a timer barring the access of the UE is operating; and deactivating the PSM setting operation when it is determined that the timer is operating. ### Claim 6 (depends on 1) The method of claim 1, further comprising: before the setting of the PSM, determining whether a timer barring the access of the UE is operating; and continuing to perform the timer operation and a timer related operation after the setting of the PSM when it is determined that the timer is operating. ### Claim 7 (depends on 1) The method of claim 1, further comprising: before the setting of the PSM, determining whether a timer barring the access of the UE is operating; and stopping a service request until the expiration of the timer by a UE Non-Access Stratum (NAS) in the setting of the PSM, when it is determined that the timer is operating. ### Claim 8 A UE device capable of Power Saving Mode (PSM) operation control in a mobile communication system, comprising: a transceiver configured to communicate with at least one network node; and a controller configured to: set a PSM for the UE, trigger a connection request of the UE in the PSM, determine whether the connection request has been barred, deactivate the PSM and change to an active mode, when it is determined that the connection request has not been barred, and maintain the PSM setting without changing to an idle mode, when it is determined that the connection request has been barred. ### Claim 9 (depends on 8) The UE device of claim 8, wherein the controller is configured to maintain the PSM setting until the expiration of a timer that bars a Radio Resource Control (RRC) connection setting for at least the connection request. ### Claim 10 (depends on 8) The UE device of claim 8, wherein the connection request comprises at least one of: a call, signaling, or a Circuit Switched (CS) fallback, which are generated from the UE. ### Claim 11 (depends on 8) The UE device of claim 8, wherein the controller is configured to bar an operation corresponding to the connection request for a time interval during which the PSM setting is maintained. ### Claim 12 (depends on 8) The UE device of claim 8, wherein the controller is configured to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and deactivate the PSM setting operation when it is determined that the timer is operating. ### Claim 13 (depends on 8) The UE device of claim 8, wherein the controller is configured to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and continue to perform the timer operation and a timer related operation after the setting of the PSM when it is determined that the timer is operating. ### Claim 14 (depends on 8) The UE device of claim 8, wherein the controller is configured to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and stop a service request until the expiration of the timer by a UE Non-Access Stratum (NAS) in the setting of the PSM, when it is determined that the timer is operating. ### Claim 15 A non-transitory computer readable medium comprising a plurality of instructions configued to, when executed by a processor, cause the processor to: set a Power Saving Mode (PSM) for a including the processor; trigger a connection request of the device in the PSM; determine whether the connection request has been barred; deactivate the PSM and change to an active mode, when it is determined that the connection request has not been barred; and maintain the PSM setting without changing to an idle mode, when it is determined that the connection request has been barred. ### Claim 16 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the plurality of instructions further is configured to cause the processor to maintain the PSM setting until the expiration of a timer that bars a Radio Resource Control (RRC) connection setting for at least the connection request. ### Claim 17 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the connection request comprises at least one of: a call, signaling, or a Circuit Switched (CS) fallback, which are generated from the UE. ### Claim 18 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the plurality of instructions further is configured to cause the processor to bar an operation corresponding to the connection request for a time interval during which the PSM setting is maintained. ### Claim 19 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the plurality of instructions further is configured to cause the processor to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and deactivate the PSM setting operation when it is determined that the timer is operating. ### Claim 20 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the plurality of instructions further is configured to cause the processor to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and continue to perform the timer operation and a timer related operation after the setting of the PSM when it is determined that the timer is operating. ### Claim 21 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the plurality of instructions further is configured to cause the processor to: determine whether a timer barring the access of the UE is operating before the setting of the PSM, and stop a service request until the expiration of the timer by a UE Non-Access Stratum (NAS) in the setting of the PSM, when it is determined that the timer is operating.
