Abstract: A method for selecting, by a user equipment (UE), a public land mobile network (PLMN) in a wireless communication system is disclosed. The method includes attempting a registration on a PLMN selected by a user in a manual network selection mode, if the registration on the PLMN selected by the user cannot be achieved, finding one or more PLMNs offering access to restricted local operator service (RLOS), selecting a specific PLMN of the found one or more PLMNs among PLMNs contained in a RLOS PLMN list configured to a universal subscriber identity module (USIM) of the UE, and initiating a registration for an access to RLOS on the specific PLMN, thereby using RLOS with high quality and high security.

Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.

Abstract: When the amount of downlink (DL) data for a user equipment (UE), buffered by a network, exceeds a predetermined reference value, the network establishes a user plane connection with the UE by changing a connection mode with the UE. Even when a control plane connection that can be used for user data transmission exists and access to the UE is possible, the network does not transmit the DL data to the UE on the control plane connection, but transfers the DL data to the UE after the user plane connection is established.
