Method and apparatus for balancing wireless access based on centralized information
First Claim
1. A machine-implemented method, comprising:
- receiving, from a first access node in a plurality of access nodes, a request to provide service to a wireless client, wherein each of said plurality of access nodes is configured to provide wireless service to one or more clients;
selecting, from among a plurality of stored policies, a first access policy applicable to said first access node;
wherein said first access policy comprises, at least in part, one or more rules about whether to allow said first access node to provide service to said wireless client based on how many other wireless clients are being serviced by a set of access nodes associated with said first access node;
determining whether to allow said first access node to provide service to said wireless client based on said first access policy;
upon determining that said first access policy allows said first access node to provide service to said wireless client, transmitting a first message, to said first access node, that instructs said first access node to provide service to said wireless client; and
upon determining that said first access policy does not allow said first access node to provide service to said wireless client, transmitting a second message, to said first access node, that instructs said first access node to deny service to said wireless client.

Abstract
A method and apparatus for managing and balancing wireless access based on centralized information is provided. A request to provide service to a wireless client is received from a first access node in a plurality of access node. An access policy, applicable to the first access node, is selected from a plurality of stored policies. The stored policies may include a variety of rules, such as how many or which wireless clients may be serviced by an access node. A centralized manager, such as an AAA server, may perform the selection of the access policy. A determination is made as to whether to allow the first access node to provide service to the wireless client based on the selected access policy. A message that instructs the first access node whether to provide or deny service to the wireless client is transmitted to the first access node.

11. An apparatus, comprising:
-
means for receiving, from a first access node in a plurality of access nodes, a request to provide service to a wireless client, wherein each of said plurality of access nodes is configured to provide wireless service to one or more clients; means for selecting, from among a plurality of stored policies, a first access policy applicable to said first access node; wherein said first access policy comprises, at least in part, one or more rules about whether to allow said first access node to provide service to said wireless client based on how many other wireless clients are being serviced by a set of access nodes associated with said first access node; means for determining whether to allow said first access node to provide service to said wireless client based on said first access policy; means for transmitting a first message, to said first access node, that instructs said first access node to provide service to said wireless client upon determining that said first access policy allows said first access node to provide service to said wireless client; and means for transmitting a second message, to said first access node, that instructs said first access node to deny service to said wireless client upon determining that said first access policy does not allow said first access node to provide service to said wireless client. - View Dependent Claims (12, 13, 14, 15)
