20100093346 | SESSION UPDATE USING MANAGEMENT OF CAPABILITY OF TERMINAL - Management of capability information is disclosed. A server in a network acquires information about capability of a user equipment (or terminal) and manages the information in a centralized manner, to reduce signaling through a radio interface between user equipments to thus reduce a waste of radio resources. | 04-15-2010 |
20100205308 | METHOD FOR SUPPORTING SESSION MOBILITY - A session mobility support is disclosed. An application server (AS) can accurately recognize a session update by checking a Replace header, a user ID and a media element included in a session invitation message (or an SIP-based INVITE message) received from a UE (User Equipment), to thus guarantee successful mobility of a session. In addition, in order to allow the AS to accurately recognize the session update, the UE first transmits the session invitation message including the Replace header via a PS (Packet Switching domain, and then, after a response to the session invitation message is received, the UE transmits a call setup message (e.g., SETUP message) via a CS (Circuit Switching) domain. | 08-12-2010 |
20100210288 | OPTIMIZED PAGING METHOD FOR HOME (E)NODEB SYSTEM - 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. | 08-19-2010 |
20100238858 | METHOD FOR CONTROLLING ACCESS OF TERMINAL TO HOME (E)NODEB - 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. | 09-23-2010 |
20100293284 | METHOD AND DEVICE FOR SELECTING AND MANAGING MOBILITY PROTOCOL IN MOBILE COMMUNICATIONS SYSTEM - Disclosed is a method for selecting and managing a mobility protocol between a network and a terminal in a mobile communication system. When the terminal is to setup an IP tunnel for data transmission/reception with the network supporting a plurality of mobility protocols, firstly, the terminal is configured to transmit a list of terminal-supported mobility protocols and/or its preference information (e.g., information about mobility protocol preferred by the terminal) to the network, and secondly, the network is configured to determine (select) a mobility protocol of an IP tunnel for data transmission/reception with the terminal based on the information, thereby enhancing an efficiency of the resource when the IP tunnel is setup between the terminal and the network. | 11-18-2010 |
20100325286 | SESSION TRANSFER METHOD AND METHOD FOR SUPPORTING SESSION CONTINUITY - According to the present invention, a service operator can immediately transfer an ongoing session to another network, accordingly it is capable of dealing with cases that a network is required to be temporarily stopped due to repairing/checking for the network, it is required to perform a network load balancing, it is required to more effectively perform the ongoing session, and the policy of the service operator is changed. And, according to the present invention, when the ongoing session is required to be transferred later even though it is not required to be immediately transferred, or session continuity operator policy is changed, it is capable of sending the session continuity operator policy to the terminal and then allowing the terminal to transfer the ongoing session to another network according to determination by itself. | 12-23-2010 |
20110294509 | HANDOVER METHOD AND APPARATUS - 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. | 12-01-2011 |
20120009901 | METHOD FOR CONTROLLING ACCESS OF TERMINAL TO HOME (E)NODEB - 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. | 01-12-2012 |
20120039214 | METHOD FOR PROVIDING CONNECTION TYPE INFORMATION AND METHOD FOR CONTROLLING RADIO RESOURCE OF HOME (E)NODEB - 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. | 02-16-2012 |
20120039304 | SERVER FOR CONTROL PLANE AT MOBILE COMMUNICATION NETWORK AND METHOD FOR CONTROLLING ESTABLISHMENT OF CONNECTION THEREOF - 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. If it is set to a path through nodes within the another wired network, the method of controlling connection establishment may further include transmitting a connection response message including a parameter indicating whether the bearer has been set or should be set to a path through nodes within the another wired network and an address of the local gateway to the base station. | 02-16-2012 |
