20120005144 | OPTIMIZATION OF RULE ENTITIES - A method of optimizing a rules engine rule set is disclosed. The method provides for identifying groups of rule conditions within a rule table that are repetitive; determining a hash function that will effectively summarize in a condensed form the set of criteria, operations and values that distinguish the group for each respective group of the identified groups; calculating hash values per the hash functions for each row of the rule table; storing the derived hash functions, the calculated hash values, and the original rule in memory when loading; and then at run time when the rule engine is invoked: calculating the hash values using the respective hash functions associated with the rule table using the attributes provided at invocation; and skipping all rows whose hash values are different from the calculated invocation hash values. The method of optimizing rule entities is particularly useful for overcoming the longer calculation times associated with un-optimized rule tables known in the art. | 01-05-2012 |
20120005145 | CACHING OF RULES - A method of exchanging a rules engine decision tree cache is disclosed. The method provides for provision accepting a command to build a replacement rules engine decision tree cache, replacing the existing cache if the decision tree creation process is successful, retaining the existing cache if the decision tree creation process is not successful, and providing specific error messages in the event that the replacement fails. The method allows an network operator to change the rules for the rule engine without disruption of real-time service and allows for a level of error checking prior to provisioning the new decision tree. | 01-05-2012 |

20120250573 | RULES SYSTEM VERSIONS - A rules systems version coordination method is disclosed for the initiation of a rules system version and the coordination of the rules system version with other rules system versions which may be available. Particularly, the rules system versions are coordinated so that one-and-only-one is in the Active State i.e. the state in which the Policy and Charging Rules Node (PCRN) is deriving its set of policies; rules system versions may only be promoted to the Active State from a Release State; and rules system versions may only be modified when in a Draft State, from which they may be promoted to the Release State. The rules systems version coordination method is particularly useful for providing a buffer state between rules system versions undergoing modification and the rules system version currently in service. | 10-04-2012 |
