Abstract
An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool, such that an available ESQK is always selected and associated with an ongoing emergency call with no measurable impact to existing calls, even if all ESQK pool members are marked as unavailable. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, and information relating to the specific emergency E911 call (“Call Data ID”). The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected.
