Patent ID: 7643442

Claim:
A wireless network system, comprising a plurality of access elements for wireless communication with one or more remote client elements and for communication with a central control element; a central control element for supervising said access elements, wherein the central control element is operative to manage and control the wireless connections between the access elements and corresponding remote client elements, wherein the central control element is further operative to detect a session initiation message associated with a first remote client element, the session initiation message corresponding to an application layer session between the first remote client element and an end system, process the session initiation message to determine one or more Quality-of-Service (QoS) parameters, wherein one of the one or more QoS parameters is an allocation of wireless bandwidth resources of an access element; associate the one or more QoS parameters to the application layer session corresponding to the session initiation message, and forward the session initiation message to a session initiation protocol server for processing of the session initiation message; transmit the one or more QoS parameters to a first access element to which the first remote client element is associated, and wherein the first access element is operative to maintain wireless connections with one or more remote client elements; reserve wireless bandwidth of the first access element for the application layer session according to the allocation of wireless bandwidth of the QoS parameter transmitted by the central control element.
