ABSTRACT:
A radio frequency manager (12) for choosing a selective call transmitter (20 or 25) among a plurality of selective call transmitters comprises a memory (13) for storing historical data on messages previously sent, the historical data comprising for each transmitter at least a latency measurement and a message queue profile and another memory (15) for storing pending messages, each of the pending messages having current information comprising at least an associated priority for the pending messages. The radio frequency manager further comprises a sorter (21) for classifying the historical data and the current information using fuzzy logic, wherein the sorter comprises a fuzzifier (14) for generating membership values, a rule base (16) for applying a set of predetermined rules to the current input conditions to perform a mapping with the historical conditions, and a defuzzifier (18) for generating a non-fuzzy prediction recommendation from the mapping for recommending the optimum transmitter.
