Abstract

A beacon signal used in data communications, such as the IEEE 802.11, is provided with data extensions. The data extensions permit additional information to be provided by the beacon signal. Periodic beacon requests are made during connection between a wireless transmit / receive unit (WTRU) and an access point (AP) on a WLAN. A Measurement Request field corresponding to a beacon request contains a measurement duration value and channel number for which the request applies. The beacon request permits a scan mode which includes "Active Scan" mode, "Passive Scan" mode and "Beacon Table" mode.

Description

technical field [0001] The present invention relates to beacon measurement request signals and network management used in wireless slotted communications. In particular, the invention relates to network management using periodic parameter measurements, such as new beacon received power levels or signal quality. Background technique [0002] The IEEE 802.11 communication protocol allows a user to roam between multiple access points, possibly operating on the same or separate channels. IEEE 802.11 communications typically take place via a wireless LAN access point (AP), which is usually a single, stand-alone unit, but may include a network with multiple APs providing roaming capabilities. To support roaming, each AP typically transmits a beacon signal every 100 ms. Roaming stations (STAs) use this beacon to measure the strength of their presence's connection to the access point. If a STA senses a weak signal, the roaming STA can implement a reassociation service to associat...
