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 |

20120082033 | DYNAMIC CONTROL OF AIR INTERFACE THROUGHPUT - A method and network node for dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system. The method detects a type of service being utilized by the mobile terminal, and dynamically selects a target delay for the traffic between a base station and the mobile terminal. The detecting may be done by a Deep Packet Inspection (DPI) engine implemented in a core network node such as a Gateway GPRS Support Node (GGSN). When the mobile terminal activates a delay-sensitive service, the target delay is dynamically changed to a smaller value to reduce latency. When the mobile terminal deactivates all delay-sensitive services, the target delay is dynamically changed to a larger value to increase throughput. | 04-05-2012 |
20120106338 | DYNAMIC CONTROL OF AIR INTERFACE THROUGHPUT - A system, method, and network node for dynamically controlling throughput over an air interface between a mobile terminal and a radio telecommunication system. A Gateway GPRS Service Node (GGSN) receives a plurality of traffic flows for the mobile terminal and uses a Deep Packet Inspection (DPI) module to determine a target delay class for each traffic flow. The GGSN signals the target delay class of each traffic flow to a Radio Network Controller (RNC) utilizing per-packet marking within a single radio access bearer (RAB). The RNC defines a separate virtual queue for each delay class on a per-RAB basis, and instructs a Node B serving the mobile terminal to do the same. The Node B services the queues according to packet transmission delays associated with each queue. A flow control mechanism in the Node B sets a packet queue length for each queue to optimize transmission performance. | 05-03-2012 |
