Patent application numberDescriptionPublished
20090285157METHOD AND APPARATUS FOR PROVIDING VOICE CALL IN MOBILE COMMUNICATION SYSTEM AND SYSTEM THEREOF - A system is provided that provides a voice call service over a Circuit Switching (CS) domain to a User Equipment (UE) that was receiving a service in a Packet Switching (PS) domain. A Mobile Management Entity (MME) sends a paging message to the UE to provide a service in the CS domain. The MME sends a suspend request message requesting suspension of the service being provided to the UE in the PS domain, upon receiving a report message indicating that the UE has switched to the CS domain. A gateway suspends the service in the PS domain upon receiving the suspend request message from the MME.11-19-2009
20090313356METHOD AND APPARATUS FOR PRODUCTION AND USE OF DECORATED NETWORKING IDENTIFIER - A method and apparatus are provided for producing a decorated networking identifier at a client terminal for transmission to a server side element. The networking identifier is obtained at the client terminal. The networking identifier is appended with one or more extensible decorations at the client terminal creating the decorated networking identifier. The one or more extensible decorations are separated from the networking identifier by a first predetermined character. The one or more decorations each include a decoration sequence and an identifier corresponding to the decoration sequence. The identifier and the decoration sequence are separated by a second predetermined character. The decorated networking identifier is transmitted from the client terminal to the server side element.12-17-2009
20100075635ACCESS ADMISSION CONTROL METHOD AND SYSTEM FOR MOBILE COMMUNICATION SYSTEM - An access admission control method and system for and SAE/LTE system is provided for determining whether to accept or reject an access of a User Equipment (UE) to a Home evolved Node B (HeNB) based on the subscriber information of the UE. In an access admission control method according to the present invention, a HeNB or HeNB Gateway (HGW) transmits, when an access request message is received from a UE, the access request message to a Mobility Management Entity (MME) together with a CSG ID of the HeNB, and the MME determines, whether to accept or reject the access of the UE to the HeNB based on whether the CSG ID is contained in a white list associated with the UE.03-25-2010
20100210268HANDOVER METHOD AND APPARATUS IN A WIRELESS COMMUNICATION SYSTEM INCLUDING FEMTO CELLS - A handover method and apparatus for facilitating a handover of a user equipment to a femto cell in a wireless communication system supporting both the femto and macro cells. When a handover condition is detected, the user equipment acquires identity information of a target femto cell base station from system information transmitted by the target femto cell base station, decides whether to handover to the target femto cell base station, based on the identity information; and transmits a measurement report message including the identity information to a serving base station of the user equipment, when the handover is to be made.08-19-2010
20100234017Apparatus and method for controlling UE supporting dual mode - A method and an apparatus control a UE that supports a dual mode for controlling power consumption. A wireless local area network (WLAN) modem of a user equipment (UE) automatically turns on when the UE detects that the UE has entered into an area (e.g. home) that employs a home network including a femto Node B and a WLAN access point (AP). The method and apparatus may also determine whether a femto identifier received from a Node B of a home network is an identifier registered in a WLAN turn-on list stored in the UE. If the femto identifier is registered in the WLAN turn-on list, the WLAN modem of the UE is turned on.09-16-2010
20110110379METHOD AND APPARATUS FOR SETTIG UP UPLINK COMMON BEARER IN WIRELESS COMMUNICATION NETWORK - A method and apparatus for setting up an UpLink common bearer shared by a plurality of User Equipments (UEs) in a wireless communication network is provided. The apparatus includes a Serving GateWay (S-GW) for receiving a group identifier of a UE from a Mobility Management Entity (MME), sending a create bearer request message including the group identifier to a Packet Data Network (PDN) GateWay (P-GW), receiving a create bearer response message including UL common S05-12-2011

20100226350SYSTEM AND METHOD FOR COMMUNICATIONG USING INTERNET PROTOCOL - Disclosed is a system and a method for communication using different IPs, i.e. a mobile IP supporting mobility and a simple IP, according to the service by a UE. The method includes network initiated IP allocation (i.e. the network allocates different IPs to the UE) and UE initiated IP allocation (i.e. the UE directly requests an IP corresponding to a specific service). As such, the IP is selected and used based on consideration of continuity of the service to be supported by the UE.09-09-2010

20080291874HANDOVER APPARATUS AND METHOD IN A HETEROGENEOUS WIRELESS COMMUNICATION SYSTEM - Provided is a handover method, in which a call manager of a network having a Circuit Switching (CS) network, a Long Term Evolution (LTE) network, and an Internet Protocol Multimedia Subsystem (IMS) network, provides handover, from the LTE network to the CS network, to a terminal that uses one radio channel. The handover method includes upon receiving a request for handover from the terminal via a node of the LTE network, establishing a line to a Mobile Switching Center (MSC) of the CS network; sending, to the call manager, a request for a change in a session to another party's terminal in communication with the terminal, to establish an Internet Protocol (IP) bearer between the call manager and the other party's terminal; and sending a handover command to the terminal during the establishment of an IP bearer, to establish a radio channel to the base station of the CS network.11-27-2008
20090047951METHOD AND APPARATUS FOR REGISTERING LOCATION OF TERMINAL IN PACKET-SWITCHING DOMAIN - A method and apparatus for registering the location of a terminal in a PS domain in a mobile communication network are provided, in which the terminal transmits a request message requesting registration of the location of the terminal to an MME of the mobile communication network, receives from the MME a response message including an eMSC indicator indicating an eMSC connected to the MME from among a plurality of eMSCs, and registers the location of the terminal to the eMSC indicated by the eMSC indicator included in the response message if the eMSC indicator included in the response message is different from an eMSC indicator stored in the terminal.02-19-2009
20090125626Method and system for processing a control message in an Internet protocol-based mobile communication system supporting a multimedia service - A method and system for processing a message in an Internet protocol-based mobile communication system supporting a multimedia service. In the system, application servers include a representative application server and multiple backend application servers. A method for defining a control message between application servers to set up a session using the standard Internet protocol is provided. When an application server performs a call processing operation, control message processing load and control message transmission delay is reduced.05-14-2009
