A method and a device for controlling a process (10), having at least two sub-processes (20, 30), by tracking, processing and correcting variables for the product, the production means and/or any process media throughout the process line. The process flow for the first sub-process (20) is divided in
A method and a device for controlling a process (10), having at least two sub-processes (20, 30), by tracking, processing and correcting variables for the product, the production means and/or any process media throughout the process line. The process flow for the first sub-process (20) is divided into slices, each slice representing a specific volume of process flow. At least some of the measured and sampled variable values are related to its specific slice volume. Any variable value obtained is processed using a control and processing, unit (60) with means for receiving, information on variable values on-line, means for presenting (70) the process flow through the production units, means for dividing the process flow into slices, means for processing a variable value obtained, including means for relating, the variable value to is specific slice volume, means to develop one or more multivariate models based on variable values for a multiple of slice volumes and means to combine the multivariate model with a processed variable value for a specific slice volume to predict a variable value and/or a quality variable for subsequent second sub-process (30). Corrective actions are executed in the subsequent second sub-process (30) based on a processed variable value from the first sub-process (20) using, actuating, means (80) for execution of corrective action.

The protocol of claim 1 wherein a plurality of calls arrive at the first base station at different times and are pending in the queue with an identical associated priority level, the first base station processing pending calls in the queue in order of time of arrival with a call having the earliest time of arrival being assigned resources prior to calls having later times of arrival. 5. The protocol of claim 1, further including a base station acknowledgment message transmitted from the first base station to the mobile station in response to the origination message. 6.

The protocol of claim 7 wherein the a third origination message is transmitted from the first mobile station to the first base station a plurality of time subsequent to the transmission of the first PACA message and prior to the transmission of the second PACA message, each of the plurality of third origination messages including data indicative of a change in the position of the first call request within the queue. 9.
