20090268691 | HANDOVER PROCESSING METHOD, AND ACCESS POINT AND MOBILE TERMINAL FOR USE IN THE METHOD - A technology is disclosed for providing a handover processing method, and an access point and a mobile terminal used in the method, in which the handover processing method can prevent processing of a HO in a layer 2 and an HO in a layer 3 from occurring at same time simultaneously, and shorten waiting time caused by the HO. The technology includes a step of providing, by the access point, strength information held by the access point itself, the strength information that is information whether to promote a handover processing in the layer 3 or not to promote the handover processing in the layer 3, and a step of receiving, by the mobile node, the provided strength information, deciding whether to perform the handover in the layer 3 based on the received strength information, and performing the handover processing in the layer 3 based on the decision. | 10-29-2009 |
20100199332 | Access-Network to Core-Network Trust Relationship Detection for a Mobile Node - The invention provides a method for trust relationship detection between a core and access network for a user equipment. The gist is that a security tunnel establishment procedure is used so one entity, be it part of the core network or be it the user equipment itself, is provided with information to determine whether the access network is trusted or untrusted. The information may comprise a first IP address/prefix, which is initially assigned to the user equipment, upon attaching to the access network. The necessary information may further comprise a second IP address/prefix, which is an address/prefix that is allocated at a trusted entity of the core network. Depending which entity determines the trust relationship of the access network, it might be necessary to transmit either the first IP address/prefix or the second IP address/prefix or the first and the second IP address/prefix using the security tunnel establishment procedure. | 08-05-2010 |
20110026435 | HOME AGENT DISCOVERY UPON CHANGING THE MOBILITY MANAGEMENT SCHEME - The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node. This approach may also be used for path optimization when a mobile node moves from a trusted to an un-trusted access network. | 02-03-2011 |
20110110249 | OPTIMIZATION OF 3GPP NETWORK ATTACHMENT - The current invention relates to a method for a network attachment procedure and a user equipment in a wireless mobile network, the wireless mobile network comprising a user equipment with a temporary identity and at least one mobility management entity. The method comprises the steps of providing an estimation whether the user equipment is unknown at the mobility management entity and sending the user equipment's temporary identity during the network attachment procedure. If the user equipment has been estimated to be unknown at the at least one mobility management entity, the user equipment's identity is sent during the network attachment procedure. These steps are carried out by the user equipment. | 05-12-2011 |
20110216743 | OPTIMIZATION OF HANDOVERS TO UNTRUSTED NON-3GPP NETWORKS - The invention relates to a method for ensuring IP session continuity upon a handover of a mobile node to a non-3GPP network, wherein an ongoing IP session of the mobile node goes via a packet data network gateway. For non-3GPP networks it is necessary to discover a security gateway and to then establish the corresponding tunnels to the ePDG to form the new data path; a security tunnel between the mobile node and the security gateway, and an IP tunnel between the packet data network gateway and the security gateway. In order to prepare the handover to possible non-3GPP accesses, the two tunnels are pre-established, however maintained deactivated until their use is actually needed. Accordingly, when handing over to the non-3GPP network, the IP session may be continued without any significant interruption by activating the already established tunnels. | 09-08-2011 |
20120044949 | ROUTE OPTIMIZATION OF A DATA PATH BETWEEN COMMUNICATING NODES USING A ROUTE OPTIMIZATION AGENT - The invention relates to optimizing a data path between two communication nodes. A route optimization agent (ROA) is determined in the current network of the second communication node, preferably on the data path between the two communication nodes. Then, an IP tunnel is established between the first communication node and the ROA, the IP tunnel and the corresponding security association of said IP tunnel being based on the home address of the first communication node in its home network. The first communication node may have two IP tunnels based on the same home address, one to its home agent and one to the ROA. Corresponding routing entries and binding cache entries need to be established in the ROA and the first communication node so that all data packets between the two communication nodes are exchanged via the established IP tunnel over the ROA. | 02-23-2012 |
20130166687 | CONTENT TRANSMISSION DEVICE AND NETWORK NODE - Disclosed is a technique for guaranteeing high-level QoS for emergent traffic to enable the transmission of the traffic. According to the technique, when a transmission unit | 06-27-2013 |
20130232536 | DATA TRANSMISSION DEVICE AND DATA TRANSMISSION CONTROL DEVICE - Disclosed is a technique for effectively transmitting a plurality of contents under the situation securing minimum QoS. According to the technique, among a plurality of contents to be transmitted to a data reception device, two or more contents are set as main contents, and the remaining contents are set as stand-by contents. One of the two or more main contents is set as a broadcasting content to be broadcasted actually, and the remaining main content is set as a switching content. The data transmission device transmits the two main contents to the data reception device via a high-quality line (main content line) and transmits the remaining stand-by contents via a line of a quality lower than the main content line (proxy data transmission line). Contents are switched by interchanging between a broadcasting content and a switching content and interchanging between a switching content and a stand-by content. | 09-05-2013 |

In a communication system including a plurality of communication devices for performing transmission and reception of content data with each other, where an instruction to acquire an image from specific video information included in the content data being transmitted or received and store the image has been input by a user, the communication device to which the image storage instruction has been input by the user transmits the image storage instruction to the plurality of communication devices in the communication system. Thus, each of the plurality of communication devices acquires the image from the specific video information being transmitted or received and stores the image based on the image storage instruction. | 06-12-2014 |
