System and method for reliably purging statistical records

摘要

Improvements to existing statistical record memory purge procedures and processes are shown and described. Certain procedures ensure that there is adequate temporary memory for storing new statistical records before purging older statistical records from permanent memory. Certain of the procedures wait a predetermined amount of time before reevaluating whether there is adequate temporary memory for storing new statistical records. After older statistical records have been purged, certain of the procedures update any indices or pointers utilized by permanent memory. The improvements may be implemented in a telecommunications system having a plurality of managed elements, each of the managed elements potentially generating statistical data that is communicated to one or more statistics servers.
