20100172293 | Lightweight Mobility Architecture - Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains a database of currently attached devices and their current access domain location. The mobility manager may then detect, for a device registered in the database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to the considered device. The mobility manager should at least obtain an indication of such a change of access domain. In response to a detected change of access domain, the mobility manager arranges for a reconfiguration of the network to forward traffic destined to an IP address of the device in the first access domain to a new location in the second access domain. In this way, the mobility manager allows the device to keep its IP address when moving between access domains. | 07-08-2010 |
20100315992 | METHOD AND AN APPARATUS FOR PROVIDING ROUTE OPTIMISATION - A mechanism for initiating route optimization in an administrative domain. The mechanism is actualized when traffic is exchanged between at least a first mobile node and a second mobile node, said traffic taking place over at least one Local Mobility Anchor (LMA) within said administrative domain. The traffic exchange between said first and second mobile nodes within the administrative domain is detected followed by a decision to initiate route optimisation for the traffic. Thereafter an optimized route for the traffic, in which the traffic is routed directly between a first and a second mobile access gateway (MAG) serving the first and the second mobile nodes, respectively, is created. A route optimisation update is then sent directly or indirectly, to any uninformed mobile access gateway (MAG), after which the traffic is routed directly between the first and the second MAG. This method for route optimization may be applied in a Proxy Mobile IP (PMIP) context. | 12-16-2010 |

20120047200 | USER BEHAVIOR BASED MOBILE BROADBAND USER PLANE TRAFFIC GENERATION SYSTEM AND METHOD FOR REAL-LIKE MEASUREMENT GENERATION - A system, a method, and a graphical user interface testing tool are described herein for constructing a validation trace (i.e., high-speed realistic network traffic) using a real network without causing privacy concerns. In one embodiment, the method comprises the steps of: (a) providing a client device which has one or more applications operating thereon and a graphical user interface; (b) recording user interactions on the client device; (c) extracting usage scenarios from real network traffic in the real network; (d) emulating user actions on the client device according to a specific user scenario by utilizing the recorded user interactions and the extracted usage scenarios to generate additional real traffic in the real network; and (e) creating the validation trace based on the generated additional real traffic and the extracted usage scenarios. | 02-23-2012 |
20120076047 | MAINTAINING CURRENT CELL LOCATION INFORMATION IN A CELLULAR ACCESS NETWORK - A method, femto Base Station, and network service node for connecting a User Equipment UE, to local devices in a local network. The femtoBS includes a femtoBS part and a Packet Data Network Gateway, PDN-GW, part comprising a subset of PDN-GW functions. The UE sends a PDN connection request that includes a special Access Point Name, APN, which indicates the request ts for local IP access. The network service node, such as a Mobility Management Entity, MME1 includes a gateway selection mechanism that, based on the special APN1 selects the PDN GW part of the femtoBS device to serve the connection. A route optimization function in the femtoBS shortcuts the traffic between the femtoBS part and the PDN GW part, providing direct access to the local network. The UE may access the Internet through a residential gateway in the local network and a fixed access connection. | 03-29-2012 |
20120079056 | Network Cache Architecture - There is described a method and apparatus for sending data through one or more packet data networks. A stripped-down packet is sent from a packet sending node towards a cache node, the stripped down packet including in its payload a pointer to a payload data segment stored in a file at the cache node. When the stripped-down packet is received at the cache node, the pointer is used to identify the payload data segment from data stored at the cache node. The payload data segment is inserted into the stripped-down packet in place of the pointer so as to generate a full size packet, which is sent from the cache node towards a client. | 03-29-2012 |
20120173702 | Automatic Signature Generation For Application Recognition And User Tracking Over Heterogeneous Networks - An apparatus, method and computer program of automatic signature generation for application recognition and user tracking over a network is described. This apparatus, method and computer program receive a set of flows of Internet traffic, find motifs in the Internet traffic, rate the motifs by looking them up in the set of flows of Internet traffic using sequence alignment to generate a sequence, create clusters of motifs from the sequence and generate regular expressions (regexps) from the clusters of motifs to serve as traffic signatures. | 07-05-2012 |
20120213165 | LIGHTWEIGHT DATA TRANSMISSION MECHANISM - A method of sending user plane data between a user device and a network entity within a packet core network via a radio access network. The method comprises

20120281590 | CREATING AND USING MULTIPLE PACKET TRAFFIC PROFILING MODELS TO PROFILE PACKET FLOWS - Multiple packet traffic profiling models are created from known packet traffic flows that are labeled, where a label is an actual value of a factor influencing one or more characteristics of the known packet traffic flow. Features, which are different from the factors, are measured for each flow. Flow clusters are defined from the labeled traffic flows by processing their features and labels. The profiling models are created based on cluster information. When an unknown packet flow is received, the multiple packet traffic profiling models are evaluated according to a confidence and a completeness associated with each of the packet traffic profiling models. The packet traffic profiling model with a predetermined confidence and completeness is selected and applied to profile the unknown packet traffic flow. | 11-08-2012 |
20130121206 | Telecommunications Method, Protocol and Apparatus for Improved Quality of Service Handling - A telecommunications network adapted to process data packets according to the client mobile internet protocol domain is extended to provide bearer capability, such that subsessions can be used to distinguish one portion of traffic from another. A different Quality of Service (QoS) can be assigned to each bearer. The bearers can be setup by a mobile node or a home agent in the telecommunications network. | 05-16-2013 |
20130176975 | NETWORK SHARING IN AN EVOLVED PACKET CORE NETWORK - One aspect pertains to a method of enabling an Evolved Packet Core (EPC) network to implement predetermined Quality of Service (QoS) resource policies applied to subscriber/service groups operating via the network. The method comprises receiving a request for QoS resources to be provided to a bearer for traffic of a user of a subscriber/service group from which the request originated. A Resource Class (RC) parameter is assigned to the request. The RC parameter identifies a resource partition and the originating subscriber/service group, A Gx-Request that includes the RC parameter is forwarded to the EPC network to invoke application of the requested QoS resources so as to establish a bearer in accordance with the predetermined policies identifiable from the RC. Other aspects pertain to EPC network nodes configured accordingly. | 07-11-2013 |
