1. A method, comprising:
receiving a mobile device identifier associated with a mobile device, wherein the mobile device is used by a user; receiving, at the mobile device from the user, a first user-selected street address; receiving, at the mobile device, a first geographic location associated with the first user-selected street address; receiving, at the mobile device from the user, a first user-specified proximity parameter that defines a first maximum distance relative to the first geographic location; receiving, at the mobile device from the user, a second user-selected street address; receiving, at the mobile device, a second geographic location associated with the second user-selected street address; receiving, at the mobile device from the user, a second user-specified proximity parameter that defines a second maximum distance relative to the second geographic location, wherein the second user-specified proximity parameter is different than the first user-specified proximity parameter; causing a first Public Safety Answering Point (PSAP) electronic address, associated with a first PSAP, to be identified and retrieved from a database external to the mobile device based on the mobile device identifier and the first geographic location; causing a second PSAP electronic address, associated with a second PSAP, to be identified and retrieved from the database external to the mobile device based on the mobile device identifier and the second geographic location; storing the first user-selected street address, the first geographic location, the first user-specified proximity parameter, and the first PSAP electronic address in a first entry of a data structure in a memory of the mobile device; storing the second user-selected street address, the second geographic location, the second user-specified proximity parameter, and the second PSAP electronic address in a second entry of the data structure in the memory of the mobile device; obtaining, based on an initiation of an emergency call at the mobile device, a current geographic position of the mobile device; identifying, based on the initiation of the emergency call at the mobile device, a certain entry of the data structure in the memory of the mobile device in which the current geographic position of the mobile device is within a certain user-specified proximity parameter of a certain geographic location corresponding to the certain entry,
wherein the certain entry comprises the first entry, the certain user-specified proximity parameter comprises the first user-specified proximity parameter, and the certain geographic location comprises the first geographic location, orwherein the certain entry comprises the second entry, the certain user-specified proximity parameter comprises the second user-specified proximity parameter, and the certain geographic location comprises the second geographic location; retrieving a default civic address and a certain PSAP electronic address from the identified, certain entry of the data structure,
wherein the default civic address comprises the first user-selected street address and the certain PSAP electronic address comprises the first PSAP electronic address; orwherein the default civic address comprises the second user-selected street address and the certain PSAP electronic address comprises the second PSAP electronic address; and using the retrieved certain PSAP electronic address to send the retrieved default civic address to a certain PSAP for dispatching emergency services to the default civic address, wherein the certain PSAP comprises the first PSAP or the second PSAP. |
