Abstract: A method for transmitting information of a user equipment (UE) by a mobility management entity (MME) is discussed. The method according to one embodiment includes generating, by the MME, a request message including an indication of whether the UE is a closed subscriber group (CSG) member; and transmitting, by the MME, the request message to a cell. The request message is one of a UE context change request message and a handover request message. The UE context change request message is an S1 AP UE Context Modification Request message. The UE context change request message is transmitted when the UE is connected to the cell, the cell is operating in a hybrid access mode, and when the MME detects that a CSG membership of the UE to the cell has expired.

Abstract: A method for performing an inter-user equipment (UE) transfer (IUT) of a collaborative session. The method according to one embodiment is performed by a UE and includes transmitting a subscription message to a network element for requesting notification of information regarding at least one or more other UEs; receiving a subscription acceptance message in response to the subscription message; and receiving a notification message. The notification message includes the information regarding the at least one or more other UEs and a controller UE capability of controlling the collaborative session. The method according to the embodiment further includes performing a process of transferring control with respect to the collaborative session established with a remote party to a specific UE, which is checked as capable of being a controller UE based on the received information, without transferring the collaborative session to the specific UE.

Abstract: Disclosed is a method for applying an extended access barring (EAB), the method performed by a machine type communication (MTC) device and comprising: recognizing, by an upper layer of the MTC device, a change from being operated in an override low priority to being operated in a low priority; informing, by the upper layer, a lower layer that the priority has been changed; and determining, by the lower layer, whether to apply the EAB, to handle at least one of an attach request, a tracking area update request, and a service request. If the EAB is applied, a RRC connection is barred.

Abstract: A method for controlling access of a terminal to a Home (e)NodeB by a network entity, the terminal accessed to the Home (e)NodeB operated in a closed access mode or a hybrid access mode by using a specific closed subscriber group (CSG) ID. The method includes recognizing by the network entity, that an allowed access timer of the specific CSG ID with respect to the Home (e)NodeB has expired; transmitting an Update Bearer Request message to other network entity in order to change a membership of the expired CSG ID; transmitting a Bearer Modify Request message to the Home (e)NodeB in order to change a membership of the expired CSG ID; and updating a bearer with said other network entity, and a bearer with the Home (e)NodeB.

Abstract: A method of performing inter-user equipment (UE) transfer (IUT) by an Internet protocol (IP) multimedia subsystem (IMS) network in an IMS-based network system is provided. The method includes receiving from a first UE a subscription message for requesting notification of state or capability information of another UE, transmitting to the first UE a subscription acceptance message in response to the subscription message, receiving from a second UE a control message comprising an IUT flag for indicating IUT enable or disable for media flows, and transmitting to the first UE a notification message comprising information on the second UE, if the IUT flag indicates IUT enable for the media flows. It is possible to decrease a signaling overhead caused by a failure of IUT of a media flow.

Abstract: Disclosed is a method of controlling connection establishment in a server in charge of the control plane within a mobile communication network. The method of controlling connection establishment may include receiving a connection request message including a parameter indicating an identifier of a local gateway from a base station. The connection request message may include an access request message by the UE. The method of controlling connection establishment may further include determining whether a bearer for the UE is set to a path through nodes within the mobile communication network or set to a path through nodes within another wired network accessible by the local gateway by considering at least one of QoS, subscriber information for the UE, operator policy if the connection request message is received.

Abstract: A method and a server are described for supporting handover by a network node in a mobile communication system. A message related to a handover, including a first parameter indicating a cause for the handover, is received. A handover command message is transmitted to a first base station for a terminal to perform a handover to a second base station, when the network node determines that handover is needed based on the cause. A status report message including a second parameter indicating whether or not the cause for handover is solved is received. A reverse handover request message is transmitted to the second base station for the terminal to perform reverse handover to a target base station, when the network node determines that a reverse handover is needed. The network node determines whether the handover or the reverse handover is needed.

Abstract: A method of controlling handover in a server and including receiving a handover required message including information indicating that a Closed Subscriber Group (CSG) membership for a terminal in a Home (e)NodeB has expired; transmitting a handover command message to the Home (e)NodeB; receiving a status report message from the Home (e)NodeB indicating that the CSG membership for the terminal is updated; receiving information related to a CSG membership of the terminal from a Home Subscriber Server (HSS) if the terminal handover was performed from the Home (e)NodeB to another base station; determining that the terminal performs a reverse handover from the another base station to the Home (e)NodeB based on the status report message and information obtained from the HSS; and transmitting a control message to perform the reverse handover to another base station.

Abstract: There is provided a method for determining a handover. The method may comprise: determining, by User Equipment (UE), whether a timer is running, wherein the UE has accessed multiple Radio Access Technologies (RATs); if the timer is not running, performing, by the UE, a handover of a data traffic, which has been routed onto a Wireless LAN (WLAN), to an original RAT; and if the timer is running, not performing, by the UE, the handover of the data traffic, which has been routed onto the WLAN, to the original RAT. The data traffic may be been routed onto the WLAN as a result of Circuit Switched Fall-Back (CSFB) or 3GPP RAT mobility.

Abstract: There is provided a method for selecting an access point (AP), the method performed by a user equipment. The method may comprise: receiving a prioritized list with respect to APs, the prioritized list includes at least one of roaming consortium information, a network address identifier (NAI), a public land mobile network (PLMN) identifier; scanning at least one or more APs in the vicinity thereby generating an available list which includes at least one or more service set identifiers (SSIDs) and roaming consortium information; acquiring at least one or more NAIs from the roaming consortium information in the available list using pre-stored mapping information; comparing the acquired NAI with the NAI in the prioritized list to select a proper AP.

Abstract: For traffic offload via a local network, a MME may obtain from a HSS, subscription data including SIPTO related permissions defined on APN basis that indicate SIPTO prohibited, indicate SIPTO allowed excluding SIPTO via Local Network (SIPTO@LN), and/or indicate SIPTO allowed including SIPTO@LN. Then, the MME may obtain information about one or more local Gateways (GWs) capable of offloading selected traffic, such information indicating which of the one or more local GWs provides access to which Packet Data Networks (PDNs), with each PDN being identified by its associated APN. Finally, the MME may process PDN connections and/or PDN disconnections in order to support offloading of the selected traffic. The counterpart UE includes the appropriate means of hardware and/or software that is configured to support and perform SIPTO@LN.
