Method and apparatus for facilitating a fast handoff in a wireless metropolitan area network

摘要

A method and apparatus for facilitating a fast handoff for subscribers in a Wireless Metropolitan Area Network (WMAN) by establishing a hard association with a first entity by sending a hard association request to the first entity and receiving a hard association response in response to the hard association request and establishing a pending association with a second entity by sending a pending association request to a second entity and receiving a pending association response from the second entity. In one embodiment, the pending association with the second entity may be converted to a hard association.

1. A method of facilitating a fast handoff for a first wireless communication device in a wireless metropolitan area network (WMAN), the method comprising:
at the first wireless communication device:
establishing a first hard association with a first entity by sending a hard association request to the first entity and receiving a hard association response in response to the hard association request;establishing a plurality of pending associations with a plurality of second entities by sending a pending association request to each of the plurality of second entities and receiving a pending association response from each of the plurality of second entities, prior to determining a need for handoff of the first wireless communication device to one of the plurality of second entities;selecting a pending association associated with one of the plurality of second entities when the need for handoff of the first wireless communication device to one of the plurality of second entities is determined;converting the selected pending association into a second hard association;converting the first hard association into one of the plurality of pending associations, after converting the selected pending association into the second hard association;wherein the first entity is one of a second wireless communication device and a first access point, andwherein each of the plurality of second entities is one of a third wireless communication device and a second access point.
