    摘要： For providing a new and improved approach to load balancing the invention proposes a method for load balancing in a network access system (20) with a number of access devices (110, 120, 130) each of which is connected to a network (500) and allows network access to communication devices connectable to said access devices (110, 120, 130), wherein at least a subset of said number of access devices (110, 120, 130) are wirelessly interconnected, with the steps of sending a request from a communication device (204) to a first access device (130) of said number of access devices (110, 120, 130) for initiating a data flow between said communication device (204) and a destination node connected to said network (500), and determining a congestion state of the connection between the first access device (130) and the network (500). If congestion is detected, a second access device (120) is selected from said number of access devices (110, 120, 130) depending on the quality of the respective wireless connection with the first access device (130), and a data flow between the communication device (204) and the destination node is established, such that data originating from the communication device (204) is transmitted from the first access device (130) via the second access device (140) to the network (500) and data received from the network (500) is transmitted from the second access device (140) via the first access device (130) to the communication device (204).
    The invention further proposes an access device, a network server and a network access system adapted for performing the inventive method.

    摘要： A method and a IEEE 802.11e compliant WLAN to provision centralized scheduling capability for the Hybrid Coordination Function (HCF) of an IEEE 802.11e compliant QoS Access Point (101) in a QoS Basic Service Set (QBSS) comprises at least one QoS Station (102a, 102b, 102c)), wherein a fair schedule for allocation of transmission opportunity intervals is determined thereby enabling a downlink traffic stream to transmit MSDUs and/or uplink traffic streams to be transmitted by receiving polls in such a way that delay and throughput guarantees are provided for the traffic streams that are able to transmit as per their negotiated TSPEC with the QoS access point (101 under the wireless channel conditions they experience and long term fairness is ensured for traffic streams that are unable to be currently transmitted.
