Abstract
Distinct user devices may sometimes share a telephone number. Techniques described herein may provide for the assigning of a temporary telephone number for a user device, which shares a telephone number with other user devices, in certain situations, such as when the user device places a call to an emergency call center. The temporary telephone number may allow the user device to be reached and/or located by the emergency call center.
Claims20
A system, comprising:
- a memory device storing a set of processor-executable instructions;
- and
- a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to:
- receive a call notification indicating that a user device has placed a call;
- determine that the user device is associated with at least one other user device, the user device and the at least one other user device being associated with a shared first telephone number;
- assign, based on the determination, a second telephone number to the user device, the second telephone number being different from the first telephone number;
- route the call notification to a callee of the call, the call notification including the second telephone number assigned to the user device;
- and
- revoke the second telephone number after a particular duration of time has expired since the second telephone number was assigned to the user device, the revoking making the second telephone number available to assign to other callers.

A method, comprising:
- receiving, by a network device, a call notification indicating that a user device has placed a call;
- determining, by the network device, that the user device is associated with at least one other user device, the user device and the at least one other user device being associated with a shared telephone number;
- assigning, based on the determination, a temporary telephone number to the user device;
- routing the call notification to a callee of the call, the call notification including the temporary telephone number assigned to the user device;
- and
- revoking the temporary telephone number after a particular duration of time has expired since the temporary telephone number was assigned to the user device, the revoking making the temporary telephone number available to assign to other callers.
3 more elements
A system, comprising:
- a memory device storing a set of processor-executable instructions;
- and
- a processor configured to execute the processor-executable instructions, wherein executing the processor-executable instructions causes the processor to:
- assign a temporary mobile directory number (“TMDN”) to a user device that is associated with a shared mobile directory number (“MDN”), the shared MDN being associated with at least one other user device;
- receive a call notification, indicating that a call has been placed to the user device, the call notification including the TMDN;
- route the call notification to the user device, without routing the call notification to the at least one other user device that is associated with the shared MDN;
- and
- revoke the TMDN after a particular duration of time has expired since the TMDN was assigned to the user device, the revoking making the TMDN available to assign to other callers.
