20100098022 | METHOD AND APPARATUS FOR ROUTING A PACKET IN MOBILE IP SYSTEM - The invention relates to a method, apparatus and system to preferably route a packet via an IP network, and more particularly to a routing entity having a buffer storing packets from/to a mobile entity. An initiation unit ( | 04-22-2010 |
20100182917 | METHOD AND APPARATUS FOR ROUTING A PACKET IN MOBILE IP SYSTEM - The system includes a mobile node ( | 07-22-2010 |
20100182960 | VRM SELECTION - There are provided a method, a network system, and a router capable of decreasing the chance of VRM or VLM changes so as to reduce signaling, and consequently contributing to better scalability. The method is applied to mobility management used in an IP-based network system, which contains a plurality of access routers (AR), location managers (LM) and routing managers (RM), through which a mobile node (MN) transmits and receives information. According to the method, a visited routing manager (VRM) where the MN is currently located monitors the MN, an AR currently communicating with the MN discriminates whether or not the MN is moving out of its connectivity range, and the VRM discriminates whether or not the MN is moving out of its control range. Then, the method switches mobility management over from the current AR to a new AR in accordance with the discrimination results, and switches mobility management over from the current VRM to a new VRM in accordance with the discrimination result. | 07-22-2010 |
20100250733 | Method and Apparatus for Data Transfer in a Peer-to-Peer Network - A method is provided of managing traffic in a network. The method comprises applying (S | 09-30-2010 |
20100322245 | ROUTING MANAGER HIERARCHY - There are provided a scalable method for mobility management applied to an IP-based network system including a plurality of routers and a plurality of servers, a part of which serve as a home routing manager (HRM), a part of which serve as local routing managers (LRM) for individual mobile nodes. The method at least comprises the steps of sending a first query about a routing address of a destination mobile node toward the HRM, based on an activation notification (AN) from an ingress access router (AR) of the plurality of routers, triggered by a source mobile mode, from an LRM receiving the activation notification; relaying the first query via one or more intermediate routing managers (IRM) closer to the HRM until the first query reaches the HRM; and in response to the first query, sending the routing address of the destination mobile node back to the ingress access router through the relay path from the HRM. | 12-23-2010 |
20130100849 | CREATING AND USING MULTIPLE PACKET TRAFFIC PROFILING MODELS TO PROFILE PACKET FLOWS - Hybrid packet traffic flow profiling technology inspects packet headers to classify packet traffic flows using clustering models developed using unsupervised learning based on known packet traffic flows and one or more traffic classification models developed using supervised learning based on the known packet traffic flows. | 04-25-2013 |
20130148513 | CREATING PACKET TRAFFIC CLUSTERING MODELS FOR PROFILING PACKET FLOWS - Packet traffic profiling models are created based on packet headers of a packet flow at a first model aggregation level to obtain first flow information describing packet-oriented parameters of the flow. A machine learning algorithm (MLA) creates a first model based on the first information, determines if the first model achieves a first confidence level, and if not, defines multiple flow slices in the packet flow. Flow slices at a second higher model aggregation level are processed to obtain second flow information describing flow slice-oriented parameters of the packet flow, and an MLA creates a second model based on the second information to determine if the second model achieves a second confidence level. If so, the process completes; if not, further processing continues at a next level. One of the models is selected for profiling packet traffic flows. | 06-13-2013 |
20130150015 | METHOD AND APPARATUS FOR CACHING - A method and caching server for enabling caching of a portion of a media file in a User Equipment (UE) in a mobile telecommunications network. The caching server selects the media file and determines a size of the portion to be cached in the UE. The size may be determined depending on radio network conditions for the UE and/or characteristics of the media file. The caching server sends an instruction to the UE to cache the determined size of the portion of the media file in the UE. | 06-13-2013 |
20150043455 | RADIO COMMUNICATION SYSTEM FOR ASSIGNING A SHORT-LIVED C-RNTI - A radio communication system and a method for assigning a short-lived Cell Radio Network Temporary Identifier (C-RNTI) to a first user equipment performing random access to a radio network node are provided. The radio communication system registers the first user equipment as connected to the radio network node. A message for synchronizing the radio network node and the first user equipment with respect to the first time period is transferred. After the first time period has elapsed, the radio communication system maintains the first user equipment connected to the radio network node, and allows the short-lived C-RNTI to be assigned to a second user equipment. Furthermore, a first user equipment and method for enabling assignment of a short-lived C-RNTI to the first user equipment performing random access and a radio network node and method for assigning a short-lived C-RNTI to a first user equipment performing random access are provided. | 02-12-2015 |
