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 for providing connection type information in a network entity comprises: receiving, by the network entity, a connection request message including access mode information indicating at least one of an open access mode, a closed access mode, and a hybrid access mode, from a Home (e)NodeB having received a request from a terminal; determining, by the network entity, a connection type of the terminal based on the access mode information and the terminal's subscriber information; and transmitting, by the network entity, a connection accept message including information about the determined connection type, to the Home (e)NodeB, such that the Home (e) NodeB performs a radio resource control function with respect to the connection with the terminal.

Abstract: A method for performing inter-user equipment (UE) transfer (IUT) of collaborative session control performed by a UE in a network system based on an Internet protocol (IP) multimedia subsystem (IMS) is provided. The method includes transmitting to an IMS network element a subscription message for requesting notification of information regarding other UE, receiving from the IMS network element a subscription acceptance message in response to the subscription message, receiving from the IMS network element a notification message comprising information regarding at least one different UE, and if a UE for transferring the collaborative session control is selected by the at least one different UE, performing a process of transferring the collaborative session control to the selected UE. A signaling overhead caused by a failure in the transfer of collaborative session control can be reduced.

Abstract: A method for controlling access of a terminal, which is connected to a Home (e)NodeB operated in a closed access mode, the method comprises: determining whether a timer, which designates allowable time to access to the Home (e)NodeB by using a specific closed subscriber group (CSG) ID, has expired; comparing an allowed CSG list for the terminal with a CSG ID list of the Home (e)NodeB if the allowed access timer has expired; and changing the specific CSG ID of the terminal into another CSG ID such that service to the terminal from the Home (e)NodeB is maintained if there is the another CSG ID in both the allowed CSG ID list for the terminal and the CSG ID list of 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 in which in case where it is inappropriate for a particular Home (e)NodeB providing a service to a particular UE to continue to provide the service on the ground of a changed status, such as overload, temporary drop due to maintenance, expiry of CSG membership for the UE, increase of temporary interference, policy change, or the like, the Home (e)NodeB transmits information on a cause that the UE performs a handover to another base station to an control entity within a network. Furthermore, it is allowed for the entity within the network to store information on the cause. In addition, if the status of the particular Home (e)NodeB is changed, then the entity within the network is allowed to perform a reverse handover for the UE to the particular Home (e)NodeB on the basis of the information on the changed status and the information on the cause.

Abstract: The disclosed embodiments relate to a multimedia data encoding/decoding method and apparatus. In some aspects, an encoding method includes generating a file type area having information on a file format; generating a data area comprising a plurality of media data areas; and generating a media information area comprising a plurality of track areas corresponding to the plurality of media data areas, respectively. According to one aspect, the multimedia data encoding/decoding method and apparatus can construct a slide show using only a small amount of multimedia data. Thus, a time taken to process and transmit the multimedia data can be reduced.

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 comprises: 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: An optimized paging method for a Home (e)NodeB system comprises: receiving, by a network entity, a notification message indicating whether downlink data for a terminal exists or not; determining, by the network entity, one or more Home (e)NodeBs to which a paging message is to be transmitted among one or more base stations included in a base station list for the terminal, based on an access mode of the Home (e)NodeB, and based on whether the terminal is a member of a Closed Subscriber Group (CSG) supported by the Home (e)NodeB; to transmitting, by the network, a paging message to the determined one or more Home (e)NodeBs or (e)NodeBs included in the base station list; and receiving, by the network, a paging response message from a specific (e)NodeB or Home (e)NodeB among the one or more (e)NodeBs or Home (e)NodeBs to which the paging message has been transmitted.
