Embodiment Construction

[0016] Such as figure 1 As shown, a plurality of wireless LANs exist in areas such as buildings, communities, and campuses. A WLAN includes access points (APs) and associated stations (STAs). A WLAN is also referred to as a Basic Service Set (BSS). An access point discloses (provides, reports, broadcasts, sends, forwards) its WLAN / BSS traffic load or Quality of Service (QoS) traffic load in its beacon or other management (control) signals (frames, packets). Quality of Service (QoS) traffic is traffic that requires certain QoS such as packet loss rate, delay and throughput. Such QoS traffic includes video and voice streams (flows). The QoS traffic load of a WLAN / BSS exposed by an AP includes all QoS traffic of the AP and its associated STAs in this WLAN / BSS. In addition, the access point discloses (provides, reports, propagates) in its beacon or other management (control) signals (frames, packets) the traffic load or QoS traffic load. An AP can learn the QoS traffic load ...

Abstract

Described herein are a method and apparatus including calculating an aggregate peak total traffic demand for all overlapping access points in an interference range, comparing the aggregate peak total traffic demand to a threshold, rejecting a requested new quality of service traffic stream responsive to results of the comparison, calculating a peak total traffic demand for each overlapping access point in the interference range if the requested new quality of service traffic stream is admissible responsive to results of the comparison, comparing the peak total traffic demand for each overlapping access point in the interference range, if the requested new quality of service traffic stream is admissible, to the threshold and one of accepting the requested new quality of service traffic stream and rejecting the requested new quality of service traffic stream responsive to results of the second comparison.

Description

technical field [0001] The present invention relates to cooperation between overlapping wireless networks. In particular, the present invention relates to channel selection and channel sharing between wireless networks that overlap and operate on the same channel. Background technique [0002] In multicast and broadcast applications, data is sent from a server to multiple receivers over a wired and / or wireless network. A multicast system as used herein is a system in which a server sends the same data simultaneously to multiple receivers, the receivers forming a subset of all receivers up to and including all receivers. A broadcast system is one in which a server sends the same data to all receivers simultaneously. That is, a multicast system may by definition include a broadcast system. [0003] A station may be any wireless device including, but not limited to, computers, laptops, notebooks, personal digital assistants (PDAs), dual-mode smartphones, user equipment, clie...
