Abstract:
1. A method for admission control comprising: a base station maintaining parameters for admission control in an admission control parameters database, wherein the base station parameters include an available time parameter for each of a plurality of access categories and a total available time parameter for all access categories; the base station receiving an admission request for a traffic stream associated with an access category; the base station determining whether to accept or deny the admission request based on a requested medium time for the requested traffic stream, a maximum time allocated for the access category associated with the admission request, wherein a minimum time is reserved and available for each ACM enabled access category, a currently allocated time for the access category associated with the admission request, and a maximum available time reserved for all ACM enabled access categories that does not include a medium time which is reserved for non-ACM enabled access categories; wherein the base station accepts the admission request on a condition that the requested medium time is less than or equal to a difference between a maximum available time allocated and currently allocated time for the access category associated with the admission request and less than or equal to a difference between the maximum available time reserved for all ACM enabled access categories and a sum of the currently allocated medium time access across all ACM enabled access categories, otherwise the base station denies the admission request; and on a condition that the admission request is accepted, updating the available time parameter for the access category associated with the admission request, the actual used time per traffic stream, the currently allocated time per traffic stream, and the total available time parameter across all ACM enabled access categories.
