These systems and methods may include identifying from network traffic that a nearby mobile device has initiated an emergency communication. These systems and methods may include determining a location where an emergency situation exists based on location information corresponding to the emergency communication, and determining whether a user of the mobile device has a registered attribute corresponding to an emergency type identified from keywords or metadata of the emergency communication. The alert may be generated in response to determining that the user has the registered attribute. ## Claims ### Claim 1 A method performed by a mobile device, the method comprising: identifying from network traffic based on wireless signals received by the mobile device, at a processor of the mobile device, that a nearby mobile device has initiated an emergency communication to an emergency service system, the nearby mobile device within a communication range of the mobile device, and the emergency communication identifiable via the network traffic; determining a location where an emergency situation exists based on location information corresponding to the emergency communication; determining whether a user of the mobile device has a registered attribute corresponding to an emergency type identified from keywords or metadata of the emergency communication; and in response to determining that the user has the registered attribute, generating an alert on the mobile device including the location and information related to the emergency situation. ### Claim 2 (depends on 1) The method of claim 1, wherein the location is based on a location of the nearby mobile device. ### Claim 3 (depends on 1) The method of claim 1, wherein the registered attribute includes at least one of CPR knowledge, firefighting training, medical training, crowd control training, law enforcement training, or suicide counseling and wherein the emergency type includes an injury, a fire, a medical emergency, a crowd emergency, or a law enforcement emergency. ### Claim 4 (depends on 1) The method of claim 1, wherein the method is performed as a background process and is opaque to the user until the alert is provided. ### Claim 5 (depends on 1) The method of claim 1, further comprising notifying a set of other mobile devices at the location that the emergency situation exists. ### Claim 6 (depends on 5) The method of claim 5, wherein notifying the set of other mobile devices includes setting a beacon indicating the emergency situation exists at the location. ### Claim 7 (depends on 1) The method of claim 1, further comprising, determining the location based on signal strength information between the nearby mobile device and each of a group of notified mobile devices. ### Claim 8 (depends on 1) The method of claim 1, wherein identifying that the nearby mobile device has initiated the emergency communication includes detecting a beacon activated by the nearby mobile device. ### Claim 9 (depends on 1) The method of claim 1, further comprising automatically retrieving a tutorial or video relevant to the registered attribute. ### Claim 10 (depends on 1) The method of claim 1, further comprising providing instructions for managing the emergency situation to the user via a voice assistant. ### Claim 11 A mobile device for providing an emergency service, the mobile device comprising: one or more hardware processors; a memory, storing instructions, which when executed, cause the one or more hardware processors to perform operations comprising: identifying from network traffic based on wireless signals received by the mobile device, at a processor of the mobile device, that a nearby mobile device has initiated an emergency communication to an emergency service system, the nearby mobile device within a communication range of the mobile device, and the emergency communication identifiable via the network traffic; determining a location where an emergency situation exists based on location information corresponding to the emergency communication; determining whether a user of the mobile device has a registered attribute corresponding to an emergency type identified from keywords or metadata of the emergency communication; and in response to determining that the user has the registered attribute, generating an alert on the mobile device including the location and information related to the emergency situation. ### Claim 12 (depends on 11) The mobile device of claim 11, wherein the location is based on a location of the nearby mobile device. ### Claim 13 (depends on 11) The mobile device of claim 11, wherein the registered attribute includes at least one of CPR knowledge, firefighting training, medical training, crowd control training, law enforcement training, or suicide counseling and wherein the emergency type includes an injury, a fire, a medical emergency, a crowd emergency, or a law enforcement emergency. ### Claim 14 (depends on 11) The mobile device of claim 11, wherein the one or more hardware processors are further configured to perform operations comprising automatically retrieving a tutorial or video relevant to the registered attribute. ### Claim 15 (depends on 11) The mobile device of claim 11, wherein the one or more hardware processors are further configured to perform operations comprising notifying a set of other mobile devices at the location that the emergency situation exists. ### Claim 16 (depends on 15) The mobile device of claim 15, wherein notifying the set of other mobile devices includes setting a beacon indicating the emergency situation exists at the location. ### Claim 17 (depends on 11) The mobile device of claim 11, wherein the one or more hardware processors are further configured to perform operations comprising determining the location based on signal strength information between the nearby mobile device and each of a group of notified mobile devices. ### Claim 18 (depends on 11) The mobile device of claim 11, wherein identifying that the nearby mobile device has initiated the emergency communication includes detecting a beacon activated by the nearby mobile device. ### Claim 19 An apparatus for providing an emergency service, the apparatus comprising: means for identifying from network traffic based on wireless signals received by the mobile device, at a processor of the mobile device, that a nearby mobile device has initiated an emergency communication to an emergency service system, the nearby mobile device within a communication range of the mobile device, and the emergency communication identifiable via the network traffic; means for determining a location where an emergency situation exists based on location information corresponding to the emergency communication; means for determining whether a user of the mobile device has a registered attribute corresponding to an emergency type identified from keywords or metadata of the emergency communication; and in response to determining that the user has the registered attribute, means for generating an alert on the mobile device including the location and information related to the emergency situation. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the location is based on a location of the nearby mobile device.
