20120214445 | NAT TRAVERSAL FOR LOCAL IP ACCESS - The invention relates to a method for traversing a NAT device residing in a backhaul IP network. A home cellular base station (HeNB) and a collocated local gateway (L-GW) providing access to a local IP network are connected to a mobile operator's packet core network through the NAT device. The method comprises the steps of opening an IPsec tunnel between the home cellular base station (HeNB) and a security gateway (SeGW) via the NAT device, and of tunneling two interfaces through the same IPsec tunnel, wherein a first interface is an interface whose local endpoint is the home cellular base station (HeNB) and hose remote endpoint is a node residing in the operator's packet core network, and a second interface is an interface whose local endpoint is the local gateway (L-GW) and whose remote endpoint is a node residing in the operator's packet core network. The invention also relates to a node comprising a home cellular base station (HeNB) and a collocated local gateway (L-GW). | 08-23-2012 |

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 |
20130053028 | DEVICE AND METHOD FOR PERFORMING AN RSRVCC PROCEDURE - Method comprising steps of at a network entity: —receiving a Routing Area Update message from a UE, —checking whether the Update Type of the Routing Area Update message is Routing Area Update, and —transmitting to a MSC a message containing information related to the network entity if the Update Type of the Routing Area Update message is Routing Area Update. | 02-28-2013 |
20130115982 | METHOD OF EXCHANGING SMS DATA IN A WIRELESS COMMUNICATIONS SYSTEM - The system comprises wireless user equipment (UE) and a core network unit interfaced with the UE through a wireless access network. A first short message relay (SMR) entity and a first short message control entity (SMC) are provided in the core network unit or the UE, the other one having a second SMR entity and a second SMC entity. The method of exchanging SMS data comprises, in the first SMC entity:—transmitting to the second SMC entity first control protocol data (CP_DATA) conveying relay protocol data (RP_DATA) provided by the first SMR entity,—receiving from the second SMC entity second CP_DATA conveying relay protocol acknowledgement information (RP_ACK) from the second SMR entity; and—retransmitting the first CP_DATA unless an acknowledgement is received from the second SMC entity before a timer expires. The second CP_DATA is interpreted as an acknowledgement for deciding whether the first CP_DATA is to be retransmitted. | 05-09-2013 |
20130142168 | DEVICE AND METHOD FOR PERFORMING AN RSRVCC PROCEDURE - Method for performing an rSRVCC procedure from UTRAN/GERAN to E-UTRAN/HSPA, comprising steps of:—receiving, a first network entity, a first message from a UE before an rSRVCC handover procedure from UTRAN/GERAN to E-E-UTRAN/HSPA involving the UE, the first message containing a pre-allocated transport address to he used for voice alter the rSRVCC handover,—sending a second message, during the rSRVCC handover procedure of a voice call, to a second network entity, the second message comprising information related to the transport address of the UE to give an instruction to send the voice media of the call to that transport address. | 06-06-2013 |
