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.
