The method of controlling a LIPA service may further include determining whether the terminal can use a LIPA service at the Home (e)NodeB by considering at least one of the LIPA related information within the initial message, the capability information within the initial message, and subscriber information of the terminal, upon receiving the initial message; storing a result of the determination; generating an access accept message including an indicator indicating whether the terminal can use a LIPA service at the Home (e)NodeB; and transmitting an initial setup message including the generated access accept message to the Home (e)NodeB. | 02-24-2011 |
20110045834 | SERVER FOR CONTROL PLANE AT MOBILE COMMUNICATION NETWORK AND METHOD FOR CONTROLLING SIPTO BASED SESSION - Disclosed is a method of controlling a session in a serving server taking charge of the control plane within a mobile communication network. The control method may include receiving, by the serving server, a tracking area update (TAU) request message of a terminal from a target base station; retrieving, by the serving server, a previous server that has taken charge of the control plane for the terminal; receiving, by the serving server and from the retrieved previous server, a context response message comprising information indicating that a session for the terminal had been established to be passed through a path over the nodes within a fixed network different from a mobile communication network; deciding, by the serving server, whether gateway relocation is needed; releasing, by the serving server, the established session; transmitting, by the serving server, an accept message comprising information for the processing result to the terminal through the target base station; and establishing, by the serving server a session passing through a path over the nodes within a fixed network different from a mobile communication network based on the information. | 02-24-2011 |
20110090848 | METHOD FOR DETERMINING ISR ACTIVATION IN MOBILE COMMUNICATIONS SYSTEM - Disclosed is a method for determining Idle mode Signaling Reduction (ISR) activation in a mobile communications system. | 04-21-2011 |
20110161508 | METHOD FOR CONTROLLING SESSION AND SERVER USING THE SAME - Disclosed is a method for masking media flows against a discovery procedure for inter-UE transfer. According to the method, when a Service Centralization and Continuity Application Server (SCC AS) establishes a session, an User Equipment (UE) is able to indicate to the network that some or all of the media flow composing a session are not discoverable from other UEs. Therefore, when the SCC AS receives the request for discovery for discovery of the ongoing session on any UE, the SCC AS identifies which media flows in the ongoing session of the UE are indicated as indiscoverable, and does not send information about theses media flows to the other UEs | 06-30-2011 |
20120179790 | METHOD FOR ALLOCATING AN IP ADDRESS TO MOBILE COMMUNICATION USER EQUIPMENT - Disclosed is a method of allocating an IP address in a mobile communication system. The method of allocating an IP address includes: receiving a PDN connection request message including one or more of version information indicating an IP version requested from a UE and information regarding capability of the UE; obtaining subscriber information of the UE from a subscriber information server in response to reception of the PDN connection request message; checking the IP version information included in the PDN connection request message; when an address of IPv6 is requested according to the checking of the version information, determining whether or not the UE moves frequently or substantially stationary on the basis of one or more of the subscriber information of the UE, the capability information of the UE, and a TAU (Tracking Area Update) frequency; and when the UE is substantially stationary, transmitting a request message including particular indication information indicating to maintain router information although a timer with respect to the router information expires so long as the UE belongs to a particular PDN gateway and information corresponding to an interface ID allocated for the UE, to the UE. | 07-12-2012 |
20120258704 | METHOD FOR DETERMINING ISR DEACTIVATION IN MOBILE COMMUNICATIONS SYSTEM - The present invention relates to a mobile communications system, and particularly, to a method for determining whether to keep or deactivate an activated Idle mode Signaling Reduction (ISR) feature for a terminal in a mobile communications system. In case of the UE's intra-SGSN mobility and intra-MME mobility, when deciding, by a mobility management node, ISR activation for a UE in an IMS network environment where heterogeneous mobile communications networks (e.g., E-UTRAN and UTRAN/GERAN) interwork with each other, considered are not only whether the mobility management node can support an ISR feature, and whether the UE can use IMS voice, but also conditions (information) on whether each mobility management can support IMS voice over PS session. This may allow an incoming voice call to the UE from the IMS network to be delivered through a first trial, to a domain (PS domain or CS domain) selected with consideration of access network situations. | 10-11-2012 |
20120282956 | Method for Transmitting MTC Data in a Mobile Communication System - The present invention relates to a mobile communication system, and more particularly relates to a method for transmitting a small-sized control signal (also known as “small data”) using a control plane in a MTC (machine-type communication) service in a mobile communication system. In the present invention, MTC data is encapsulated in an existing control procedure or control message or the like, on a control signal, without performing packet data bearer setup, and the control signal having the encapsulated MTC data is sent between a network and a terminal, thereby optimizing network resource efficiency and reducing the wireless channel load. | 11-08-2012 |
20130017829 | METHOD FOR PERFORMING OFFLINE INDICATION OF MACHINE TYPE COMMUNICATION DEVICE IN MOBILE COMMUNICATION SYSTEM - The present invention relates to a mobile communication system and, more particularly, to a method for performing offline indication of a machine type communication (MTC) device in an MTC service. A network entity checks (or searches) whether or not an MTC device is out of monitoring or management because it is in an offline state. A network entity repeatedly transmits a signal for checking whether or not the UE is currently in an offline state to the UE during operation time of a timer, namely, during a detection time, or checks a signal (e.g., a message of an attach procedure, a message of a location registration procedure, and the like) transmitted by the UE during the detection time to check whether or not the UE is in an offline state. When the UE is checked to be in an offline state, the network entity informs an MTC server or an MTC user accordingly, to thus automatically manage a loss, malfunction, or the like, of the MTC device. | 01-17-2013 |
20130041954 | Method of Sharing One or More Media in a Session Between Terminals - In a first embodiment, a specific UE is enabled to copy all or a portion of one or more or media in an ongoing session with a remote end to another UE, so that the media can be shared by many UEs. In a second embodiment, when a specific UE shares all or a portion of media in an ongoing session with another UE, the shared media may be controlled. | 02-14-2013 |
20130182607 | CONTROL METHOD AND DEVICE BASED ON MULTIPLE PRIORITIES IN WIRELESS COMMUNICATION SYSTEM - A wireless communication system is disclosed. More particularly, a control method and device based on multiple priorities in a wireless communication system is disclosed.
