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. A method of recyclably using an emergency services key selected from among a limited size pool, comprising: selecting an emergency services key from a limited size pool having an older timestamp associated with said emergency services key from among those in said pool, in an event that no emergen
1. A method of recyclably using an emergency services key selected from among a limited size pool, comprising: selecting an emergency services key from a limited size pool having an older timestamp associated with said emergency services key from among those in said pool, in an event that no emergency services key in said pool meets a first attempt selecting criteria; andresetting a timestamp associated with said selected emergency services key to a current time plus a value of a guard timer;wherein selection of said emergency services key is assured to be available when selected. 2. The method of recyclably using an emergency services key selected from among a limited size pool according to claim 1, wherein: said older timestamp associated with said selected emergency services key has an oldest timestamp from among those that are available in said limited size pool. 3. A method of recyclably using an emergency services key selected from among a limited size pool, comprising: selecting an emergency services key from a limited size pool having an older timestamp associated with said emergency services key from among those in said pool, in an event that no emergency services key in said pool meets a first attempt selecting criteria;resetting a timestamp associated with said selected emergency services key to a current time plus a value of a guard timer; andif a hold timer is associated with said selected emergency services key, resetting a timestamp associated with said selected emergency services key to a current time plus a value of said hold timer, said hold timer being of greater value than any guard timer associated said selected emergency services key;wherein selection of said emergency services key is assured to be available when selected. 4. The method of recyclably using an emergency services key selected from among a limited size pool according to claim 1, wherein: said emergency services key is an emergency services query key (ESQK). 5. The method of recyclably using an emergency services key selected from among a limited size pool according to claim 1, wherein: said emergency services key is an emergency services routing key (ESRK). 6. Apparatus for recyclably using an emergency services key selected from among a limited size pool, comprising: means for selecting an emergency services key from a limited size pool having an older timestamp associated with said emergency services key from among those in said pool, in the event that no emergency services key in said pool meets said first attempt selecting criteria; andmeans for resetting a timestamp associated with said selected emergency services key to a current time plus a value of a guard timer;wherein selection of said emergency services key is assured to be available when selected. 7. The apparatus for recyclably using an emergency services key selected from among a limited size pool according to claim 6, wherein: said older timestamp associated with said selected emergency services key has an oldest timestamp from among those that are available in said limited size pool. 8. The apparatus for recyclably using an emergency services key selected from among a limited size pool according to claim 6, further comprising: means for selecting an emergency services key from a limited size pool having an older timestamp associated with said emergency services key from among those in said pool, in the event that no emergency services key in said pool meets said first attempt selecting criteria;means for resetting a timestamp associated with said selected emergency services key to a current time plus a value of a guard timer; andmeans for resetting a timestamp associated with said selected emergency services key to a current time plus a value of said hold timer, if a hold timer is associated with said selected emergency services key, said hold timer being of greater value than any guard timer associated said selected emergency services key;wherein selection of said emergency services key is assured to be available when selected. 9. The apparatus for recyclably using an emergency services key selected from among a limited size pool according to claim 6, wherein: said emergency services key is an emergency services query key (ESQK). 10. The apparatus for recyclably using an emergency services key selected from among a limited size pool according to claim 6, wherein: said emergency services key is an emergency services routing key (ESRK).
