PACKET SWITCHED RADIO CHANNEL ADMISSION CONTROL IN A CELLULAR TELECOMMUNICATIONS SYSTEM

摘要

A method and system for controlling admission to a packet switched radio channel (PRCH) is provided. A PRCH admission control function (416) evaluates admission requests for users requesting admission to a PRCH. The admission requests each contains a priority value and an estimated data traffic for the requesting user. If the estimated data traffic from one or more packet calls currently using the PRCH and having a priority equal to or higher than the priority of the requesting user, plus the estimated data traffic required by the requesting packet call are less than a maximum tolerable traffic level, the packet call is granted admission (710).
