In a data communication system a first controller (102) selectively retrieves data from a database (316) in a second controller (106). Data corresponding to a plurality of entities is programmed (602) into the database. The data includes a plurality of parameters for each of the plurality of entities. Ones of the plurality of parameters are selectively defined (604) to belong to parameter groups in accordance with a predetermined grouping plan. The first controller generates (612) a request for the data corresponding to one of the plurality of entities from the database, the request further indicating a desired one of the parameter groups. The second controller returns (620) the desired one of the parameter groups corresponding to the one of the plurality of entities, in response to the request.

A message sender (120, 700) and an output controller (110, 600) having an output configuration recover from a configuration error in a communication system. The output controller defines (404) a current output configuration tag (220) for identifying a current output configuration (212) in response to the output configuration being changed to the current output configuration. The message sender sends (506) to the output controller a recorded configuration tag corresponding to the output controller, in response to having a message to send to the output controller. The output controller and the message sender cooperate (512) to recover from the configuration error produced when the recorded configuration tag is different from the current configuration tag.

A paging controller (10) assigns pages to particular batch positions utilizing a metric that minimizes the gaps between messages in a batch so as to increase the efficiency and throughput of the system. The controller (10) stores information representing messages that are received for transmission in a queue (31-38) having the same associated frame number as the frame number of the message. A metric value representing a distance between an end of a message, if it is placed in a batch starting at a position associated with the message's frame number, and a subsequent batch position is calculated for the received messages identified in the queues (31-38). Messages are assigned to positions in the batches based upon the shortest calculated distance value so as to substantially minimize the gaps between adjacent messages in the batches.
