Quality of service provisioning through adaptable and network regulated channel access parameters

摘要

One or more system and/or method of dynamically setting values of Channel Access Parameters employing a Load Supervision Manager entity, a Quality of Service Parameters Manager entity, and an Access Point. The entities work with the Access Point and continuously monitors network loading conditions and setting Channel Access Parameters values in response to network loading conditions. The Load Supervision Manager is a controlling and/or supervisory entity that sits at a network level receives information from the QoS Parameters Manager which sits at a subnet level, and judges prevailing loading conditions. The prevailing loading conditions include such factors as the number of Mobile Nodes and the applications or ACs they are running on in each subnet. The QoS Parameters Manager assesses the possible near future loading condition in each subnet including monitoring the hand-off Mobile Nodes and issues directives to QoS Parameters Managers.

1. A method of dynamically setting values of Channel Access Parameters, comprising:
implementing a Load Supervision Manager entity and a Quality of Service (QoS) Parameters Manager entity, said entities provided for working with at least one Access Point; continuously monitoring network loading conditions using the entities; and setting Channel Access Parameters values with the entities in response to the network loading conditions; wherein said Load Supervision Manager is a controlling and/or supervisory entity, sits at a network level, receives information from said QoS Parameters Manager sitting at subnet levels, and judges prevailing loading conditions, said prevailing loading conditions including at least one of a number of Mobile Nodes, and applications or Access Categories (ACs) they are running on in each subnet, and said Load Supervision Manager assesses the possible near future loading condition in each subnet including monitoring hand-off Mobile Nodes and issues directives to QoS Parameters Managers; wherein said Load Supervision Manager performs the following: a) periodically gets from the QoS Parameters Manager Current Load Information and from this information establishes Predicted Load Demand served by each Access Point; b) receives a copy of a message from a MAC Layer Management Entity of an Access Point through the QoS Parameters Manager of the cell where a Mobile Node is currently present, when the Mobile Node moves from one subnet to another, c) extracts from said message, (i) Source Address of the Access Point where the Mobile Node currently resides; (ii) Destination Address of the Access Point to which said Mobile Node intends to move and has requested Pre-authentication, and (iii) Current IP Address of said Mobile Node belonging to the network where the Mobile Node currently resides, and uses this information in assessing and predicting load conditions.
