Temporary assignment of emergency route back
An emergency route back number (ERBN) may be assigned for use in emergency calls. A telecommunication network associated that may be associated with a wireless service provider, may identify an emergency call directed to an emergency number (e.g., 9-1-1) that originated from a device that is not associated with a unique phone number such as a shared line, or a communication that utilizes some other indicator to establish the emergency call (e.g., an email address, or some other identifier). When an emergency call is detected that does not have a dedicated phone number, an ERBN is assigned to the communication. This ERBN may be reserved for some period of time after the emergency call ends such that emergency contact centers are able to reach callers back in case of dropped calls, fails, and/or additional emergency services that may need to reach the callers directly.
1. A system comprising:
one or more processors;
a memory; and
one or more components stored in the memory and executable by the one or more processors to perform operations comprising:
receiving, from a user equipment (UE) associated with a wireless telecommunications network, a request to establish an emergency call with a Public Safety Answering Point (PSAP);
identifying that the UE is associated with a non-unique telephone number, and the non-unique telephone number is associated with a hunt group;
temporarily associating an emergency route back number (ERBN) with the UE during the emergency call and at least for at least a period of time after the emergency call has ended;
in response to receiving a subsequent request from the UE to establish a subsequent emergency call with the PSAP prior to an expiry of the period of time after the emergency call has ended, re-starting the predetermined period of time; and
removing the association of the ERBN with the UE upon an occurrence of one or more events after the subsequent emergency call has ended.
2. The system of claim 1 , wherein associating the ERBN with the UE comprises obtaining the ERBN from a group of available ERBNs.
3. The system of claim 1 , wherein the operations further comprise providing the ERBN to one or more of the PSAP and the UE.
4. The system of claim 1 , wherein the operations further comprise determining that the subsequent emergency call has ended and maintaining the association of the ERBN with the UE for the period of time.
5. The system of claim 4 , wherein removing the association of the ERBN with the UE upon the occurrence of the one or more events comprises determining that the period of time has passed after the subsequent emergency call has ended and removing the association.
6. The system of claim 1 , wherein removing the association of the ERBN with the UE comprises returning the ERBN to a pool of ERBNs that are available for assignment by a component within the wireless telecommunications network.
7. A method comprising
receiving, from an over-the-top (OTT) client of a user equipment (UE) associated with a wireless telecommunications network, a request to establish an emergency call;
based on the emergency call being received from an OTT client, temporarily associating an emergency route back number (ERBN) with the UE during the emergency call and at least for at least a period of time after the emergency call has ended;
in response to receiving a subsequent request from the OTT client to establish a subsequent emergency call prior to an expiry of the period of time after the emergency call has ended, re-starting the predetermined period of time; and
removing the association of the ERBN with the UE upon an occurrence of one or more events after the subsequent emergency call has ended.
8. The method of claim 7 , wherein associating the ERBN with the UE, comprises one or more of generating the ERBN and obtaining the ERBN from a group of available ERBNs.
9. The method of claim 7 , further comprising providing the ERBN to one or more of a Public Safety Answering Point (PSAP) and the UE.
10. The method of claim 7 , further comprising determining that the subsequent emergency call has ended and maintaining the association of the ERBN with the UE for the period of time.
11. The method of claim 10 , wherein removing the association of the ERBN with the UE upon the occurrence of the one or more events comprises determining that the period of time has passed after the subsequent emergency call has ended and removing the association.
12. The method of claim 7 , wherein removing the association of the ERBN with the UE comprises returning the ERBN to a pool of ERBNs that are available for assignment by a component within the wireless telecommunications network.
13. A non-transitory computer storage medium having programming instructions stored thereon that, when executed by a computer system, cause the computer system to perform operations comprising:
receiving, from a user equipment (UE) associated with a wireless telecommunications network, a request to establish an emergency call with a Public Safety Answering Point (PSAP);
identifying that the UE is associated with a non-unique telephone number, and the non-unique telephone number is associated with a hunt group;
temporarily associating an emergency route back number (ERBN) with the UE during the emergency call and at least for at least a period of time after the emergency call has ended;
in response to receiving a subsequent request from the UE to establish a subsequent emergency call with the PSAP prior to an expiry of the period of time after the emergency call has ended, re-starting the predetermined period of time; and
removing the association of the ERBN with the UE upon an occurrence of one or more events after the subsequent emergency call has ended.
14. The non-transitory computer storage medium of claim 13 , wherein associating the ERBN with the UE comprises obtaining the ERBN from a group of available ERBNs.
15. The non-transitory computer storage medium of claim 13 , wherein the operations further comprise providing the ERBN to one or more of the PSAP and the UE.
16. The non-transitory computer storage medium of claim 13 , wherein the operations further comprise determining that the subsequent emergency call has ended and maintaining the association of the ERBN with the UE for the period of time.
17. The non-transitory computer storage medium of claim 16 , wherein removing the association of the ERBN with the UE upon the occurrence of the one or more events comprises determining that the period of time has passed after the subsequent emergency call has ended and removing the association.
18. The non-transitory computer storage medium of claim 13 , wherein removing the association of the ERBN with the UE comprises returning the ERBN to a pool of ERBNs that are available for assignment by a component within the wireless telecommunications network.
