ActiveUS7289453B2Minimize impactDelay minimizationError preventionTransmission systemsAdaptive servicesQos management
In the field of Quality-of-Service (QoS) management for adaptive real-time services running on mobile devices which support different access technologies in dynamic wireless Internet Protocol (IP) networks, the connectivity of the applied nodes is unpredictable time-varying. In this context, a QoS management unit (304) is proposed that allows adaptive applications with real-time requirements in typical mobile wireless scenarios—e.g. a radio link with a changing transmission quality and handover procedures (2900)—to adaptively and responsively react to a time-varying network topology and different radio link characteristics. Said QoS management unit (304) provides methods of pre-allocating, reserving, monitoring and adapting QoS-related parameters in a dynamic mobile environment.The QoS management unit (304) comprises at least one analysis unit (306) which evaluates QoS requests received from other nodes (402a / b, 404) to inform the application unit (328) of said mobile terminal (208) about the current QoS situation, at least one processing unit (312) that manages request messages (1200, 2000, 2400) for each type of QoS request, at least one monitoring unit (318) which monitors the current QoS situation within said mobile node (208) and initiates requests by activating the processing unit (312), and at least one generation unit (322) which is responsible for generating QoS requests or passing them on to the QoS management units (304) of other nodes (402a+b, 404).

A method and a system for a quality of service (QoS) point coordinator (PC) for a basic service set (BSS) in a wireless local area network (WLAN) is disclosed. The PC includes a QoS management entity (QME) and an admission control entity (ACE). The QME receives at least one reservation request message that characterizes one of a QoS session and a QoS application (session / application) that can be of a continuoustperiodic flow type that is time sensitive, or can be of a discontinuous / bursty flow type that is time tolerant.

A technique for the end terminal provided with services to handle QoS process is disclosed. According to this technique, a terminal based QoS management scheme is implemented to achieve end-to-end QoS wherein the end terminal 21 is responsible for handling of the QoS related functions. In order for QoS management to be handled at terminal, the terminal needs to know the network conditions and external state of entities in order to know what action to be taken. For example, the terminal performs monitoring and usage collection. These performance data are then reported to a central server (SLA manager 28). The central server collects these data from all terminals within its administration domain. The central server also has access to information on the QoS to be given to individual terminals, such as service level. Based on the information, the central server decides what action to be taken by individual terminal and enforces these actions into the affected terminals.

Methods And Systems For Dynamic Bandwidth Management For Quality Of Service In IP Core And Access Networks
InactiveUS20080130495A1Easy to useStringent qualityError preventionTransmission systemsPresent methodKey issues
Proper allocation of network bandwidth is a crucial issue in rendering certain performance guarantees to meet the growing customer demands. Hence, allocation methodologies must explicitly be carried out for these guarantees to be given as efficiently as possible since the shared resources are limited. This invention presents methods and systems for Dynamic Bandwidth Management (DBM) and Quality of Service (QoS) in packet-based networks. DBM is an algorithm that dynamically adjusts the resource allocation in the IP Access Networks based upon measured QoS at the IP Core Network through an implementation of a Feedback Control Mechanism to manage available core transport bandwidth. Such a Feedback Control Mechanism is capable of maintaining a condition of non-congestion, a sufficient and necessary condition to meet end-to-end QoS requirements in a Next Generation Network (NGN). The emphasis is given on the system implementation of QoS policies for the fair distribution of network resources through a scalable architecture comprising key Resource and Admission Control Functional (RACF) entities, namely: a Network Management System (NMS), a QoS Manager, an Access Controller Manager (ACM), the Access Controllers, and the active probes.

A packet network node and method of operating a packet network node are disclosed. Conventional packet network nodes react to congestion in the packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In embodiments of the present invention, indiscriminate packet discards are prevented by causing packets to be discarded on lower priority flows and flow aggregates. A further action is taken to reduce the likelihood of packet discards. When an aggregate set of flows raises a congestion alarm action is taken to try to increase the capacity of the aggregate through taking capacity from pre-assigned donor aggregates. A donor aggregate may be carrying flows, for example flows classified as best effort. Another type of donor capacity is donor re-assignable unused capacity. Aggregates may have capacity added either up to a defined limit or, temporarily, exceeding any limit provided there is free capacity available, but removable back to the defined limit when other aggregates need increased capacity and are below their defined limits.

Conventional packet network nodes react to congestion in the packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In embodiments of the present invention, indiscriminate packet discards are prevented by causing packets to be discarded according to bandwidth allocations that intelligently track flow sending rates. Flows are allocated bandwidth based on policy information. Where such policy information indicates that the flow should be treated as delay-sensitive, the present invention includes means to allocate an initial minimum rate that will be guaranteed and such flows will also have the use of an additional capacity that varies depending on the number of such flows that currently share an available pool of capacity. This provides a congestion alleviation method which is less annoying to users since communications that have been in existence for longer are less susceptible to component packets being deleted.
