Subscriber location database

A subscriber location database device, comprising:

• a memory device storing:
• location information for a plurality of user devices, the location information associating a mobile directory number (“MDN”), associated with each of the plurality of user devices, with the location information associated with the each user device, and
• a set of processor-executable instructions;
• and
• a processor configured to execute the processor-executable instructions, wherein executing the computer-executable instructions causes the processor to:
• receive, from a requestor, a request for location information associated with a particular user device, of the plurality of user devices,
• the request including an MDN associated with the particular user device;
• determine whether the requestor is authorized to access the location information associated with the particular user device;
• identify, based on determining that the requestor is authorized to access the location information associated with the particular user device, the location information, stored in the storage device, that is associated with the MDN included in the request;
• and
• provide, to the requestor, the identified location information that is associated with the MDN included in the request.

A non-transitory computer-readable medium, storing processor-executable instructions, which, when executed by one or more processors of a device, cause the one or more processors to:

• store, in a memory of the device, location information for a plurality of user devices, the location information associating a mobile directory number (“MDN”), associated with each of the plurality of user devices, with the location information associated with the each user device, and
• receive, from a requestor, a request for location information associated with a particular user device, of the plurality of user devices,
• the request including an MDN associated with the particular user device;
• determine whether the requestor is authorized to access the location information associated with the particular user device;
• identify, based on determining that the requestor is authorized to access the location information associated with the particular user device, the location information, stored in the storage device, that is associated with the MDN included in the request;
• and
• provide, to the requestor, the identified location information that is associated with the MDN included in the request.
