Abstract
A method of sleep mode and contention resolution provides management of a sleep mode in stations and backup for resolution of contention on request for service messages. This reduces the possibility of excessively delayed access to infrastructure services by providing a backup non-contending POLL for service REQUESTs which are invoked at the Access-point Hub Controller upon indication of possible contention. A fast POLL of Stations registered to that Access-point is made in the following available time with a possibility of carry-over to the next access opportunity. The length of the POLL is minimized by addressing only 'awake' Stations and omitting those in sleep mode. A slow POLL is used to transfer Stations in and out of sleep mode, and for other purposes.
