ABSTRACT:
A method and apparatus for routing information within a communication system (100) is based upon evaluating various attributes (310) of the information to be routed. The methodology employs processing steps including, but not limited to receiving a message (300) having a key (304) and a first set of message attributes (310), each attribute having a value. Extracting the key (304) from the message to index a data base (400) in order to retrieve records (410) having the key and containing a representation of a logic function (406) that describes a second set of message attributes. The first set of attributes values are applied to the logic function (406) of the first retrieved record to determine whether the function is true or false. If true, that data base record is selected for use in routing the information. Otherwise, the first set of attribute values are applied to the logic functions of each indexed data base record (410) until a true condition is encountered. This methodology is employed with the selection of a destination device as well as the selection of a communication network.
