Optimized random access scheme to a shared resource.

摘要

A method of sharing access to a resource (32) by a plurality of users (72), comprising the steps of: (a) assigning each user a priority class, at least two of the users different priority classes (40, 50); (B) providing each user with a probability corresponding to the priority class of user access; and (c) for each user, computing from a range of possible times of access to the resource an access time based on the access probability of the assigned user class; characterized in that the probability for each user class is determined from a function of a plurality of functions probability distribution where the probability is graphically displayed with respect to time is a function with slope (140, 150), in which at least two of such functions (140, 150) overlap each other, and the functions of the probability distribution are such that the time range of possible access (0 to 1) for all user classes a normalized sum of distribution functions of the likelihood that provides an overall uniform probability distribution.
