An entry describes a set of subscriber session match criteria. The set contains those subscriber session identities specified by csubJobMatchIdentities. If the corresponding row in the csubJobTable has a csubJobType of 'query', then the system builds a report containing those subscriber sessions matching these criteria. If the corresponding row in the csubJobTable has a csubJobType of 'clear', then the system terminates those subscriber sessions matching these criteria. The system automatically creates an entry when the EMS/NMS sets the corresponding instance of csubJobType to 'query' or 'clear'. Likewise, the system automatically destroys an entry under the following circumstances: 1) The EMS/NMS destroys the corresponding row in the csubJobTable. 2) The EMS/NMS sets the corresponding instance of csubJobType to 'noop'.
