Abstract: A method of controlling an access, which is controlled by a Mobility Management Entity (MME) of a control plane in a visited network; and the MME therefore are discussed. The method according to one embodiment includes receiving an access request message or an update request message requested by a roaming user equipment (UE) from a Home (e)Node B; and determining Closed Subscriber Group (CSG) information among first CSG information and second CSG information based on predefined priority information when the first CSG information conflicts with the second CSG information. The predefined priority information indicates that the first CSG information takes precedence over the second CSG information. The method further includes transmitting an accept message based on the determined CSG information via the Home (e)Node B. The first CSG information is CSG-related information defined in a home network and the second CSG information is CSG-related information in the visited network.

Abstract: One embodiment of the present specification provides a method by which a user equipment (UE) reselects a network node in charge of a control plane. The method can comprise the steps of: retransmitting, by the UE, a non-access stratum (NAS) request message if the UE transmitted the NAS request message to a network node in charge of the control plane through a base station but has not received a response message; transmitting, by the UE, an access stratum (AS) message, which includes an indication showing no response from the network node, to the base station if the retransmission of the NAS request message has repeated by a preset value or more; and reselecting another network node in charge of the control plane instead of the network node in a disabled state if information indicating that the network node is in the disabled state is received from the base station.

Abstract: A method for supporting a voice service of a user equipment (UE) in a wireless communication system; and a Mobility Management Entity (MME) apparatus therefore. The method according to one embodiment includes transmitting an update location request (ULR) message to a home subscriber server (HSS); and transmitting a Notify Request message including a single radio voice call continuity (SRVCC) capability, when the MME determines that the SRVCC capability is changed. If the MME knows a homogeneity of support of an IMS voice over PS session in all TAs (Tracking areas) or all RAs (Routing Areas) related to the MME, the ULR message includes an information element. If the MME fails to know the homogeneity of support of the IMS voice over PS session due to a lack of information including Voice over IMS related capability information of the UE, the ULR message does not include the information element.

Abstract: A disclosure of the present invention provides a method for supporting a power saving mode (PSM) in a radio device. According to the method, the radio device may transmit a first message including a first activation time value to a network entity when the radio device requires the PSM. Then, the radio device may receive a second message including a second activation time value from the network entity. The radio device may enter a PSM state on the basis of the second activation time value. When it is necessary to stop the PSM or change the second activation time, the radio device may transmit a third message at the very time point.
