An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool. 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”, information relating to the specific emergency E911 call (“Call Data ID”), a guard timer, and an optional hold timer. 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. The timestamp is reset to a current time plus a guard timer, or hold timer if desired.

1. An efficient method of using emergency services keys from a limited pool of emergency services keys, comprising: selecting, at a physical VoIP positioning center (VPC) server, an emergency services key from a pool of emergency services keys available for use by said VPC server, said selected emergency services key having a timestamp that is oldest from among said pool of emergency services keys; andresetting said timestamp associated with said selected emergency services key. 2. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said selected emergency services key is selected by said VPC further based on a NULL call data ID. 3. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said timestamp is reset to a current time associated with an emergency call to which said selected emergency services key is assigned. 4. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said timestamp is reset to a current time associated with an emergency call to which said selected emergency services key is assigned, plus an amount of guard timer. 5. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said pool of emergency services keys is a limited size pool. 6. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said emergency services keys are emergency services query keys (ESQKs). 7. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 1, wherein: said emergency services keys are emergency services routing keys (ESRKs). 8. An efficient method of using emergency services keys from a limited pool of emergency services keys, comprising: selecting, at a physical VoIP positioning center (VPC) server, an emergency services key from a pool of emergency services keys available for use by said VPC server, said selected emergency services key having a timestamp that is oldest from among said pool of emergency services keys; andresetting said timestamp associated with said selected emergency services key to a current time associated with an emergency call to which said selected emergency services key is assigned, plus a value of a hold timer greater than a guard timer associated with said selected emergency services key. 9. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 8, wherein: said selected emergency services key is selected by said VPC further based on a NULL call data ID. 10. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 8, wherein: said pool of emergency services keys is a limited size pool. 11. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 8, wherein: said emergency services keys are emergency services query keys (ESQKs). 12. The efficient method of using emergency services keys from a limited pool of emergency services keys according to claim 8, wherein: said emergency services keys are emergency services routing keys (ESRKs). 13. An efficient method of using emergency services query keys from a limited pool of emergency services query keys, comprising: selecting, at a physical VoIP positioning center (VPC) server, an emergency services query key (ESQK) from a pool of emergency services query keys (ESQKs) available for use by said VPC server, said selected emergency services query key (ESQK) having a timestamp that is oldest from among said pool of emergency services keys; andresetting said timestamp associated with said selected emergency services query key (ESQK). 14. The efficient method of using emergency services query keys from a limited pool of emergency services query keys according to claim 13, wherein: said selected emergency services query key (ESQK) is selected by said VPC further based on a NULL call data ID. 15. The efficient method of using emergency services query keys from a limited pool of emergency services query keys according to claim 13, wherein: said timestamp is reset to a current time associated with an emergency call to which said selected emergency services query key is assigned. 16. The efficient method of using emergency services query keys from a limited pool of emergency services query keys according to claim 13, wherein: said timestamp is reset to a current time associated with an emergency call to which said selected emergency services query key is assigned, plus an amount of guard timer. 17. The efficient method of using emergency services query keys from a limited pool of emergency services query keys according to claim 13, wherein: said pool of emergency services query keys is a limited size pool.
