The first mobile device executes a first application to broadcast a positioning signal based on a first communication protocol. The second mobile device receives the positioning signal to activate a second application, originally in suspended status or not-running status, installed on the second mobile device. After the second application is activated, the first application of the first mobile device communicates with the second application of the second mobile device. ## Claims ### Claim 1 A disaster emergency rescue system, comprising: a first mobile device, configured to execute a first application to broadcast a positioning signal based on a first communication protocol; and a second mobile device, configured to receive the positioning signal to activate a second application, originally in a suspended status or a not-running status, installed on the second mobile device; wherein after the second application is activated, the first application of the first mobile device communicates with the second application of the second mobile device. ### Claim 2 (depends on 1) The disaster emergency rescue system of claim 1, wherein the first mobile device communicates with the second application of the second mobile device via the first application and a mobile communication network. ### Claim 3 (depends on 1) The disaster emergency rescue system of claim 1, wherein the first mobile device periodically and alternately broadcasts the positioning signal and a communication service signal. ### Claim 4 (depends on 3) The disaster emergency rescue system of claim 3, wherein when the second application is activated, the second mobile device enables a communication service function based on a second communication protocol and the second mobile device returns a communication response signal to the first mobile device after receiving the communication service signal so as to establish a communication connection between the second mobile device and the first mobile device. ### Claim 5 (depends on 4) The disaster emergency rescue system of claim 4, wherein after the communication connection is established, the first mobile device calculates a distance between the second mobile device and the first mobile device according to a strength of a returned signal of the second mobile device and displays the distance. ### Claim 6 (depends on 1) The disaster emergency rescue system of claim 1, wherein after the second application is activated, the second mobile device transmits a user data to the first mobile and the first mobile device displays the user data via the first application. ### Claim 7 (depends on 6) The disaster emergency rescue system of claim 6, wherein the user data comprises a healthy data. ### Claim 8 (depends on 7) The disaster emergency rescue system of claim 7, wherein the user data further comprises one or more of a personal data, an operational record data and an action record data. ### Claim 9 (depends on 8) The disaster emergency rescue system of claim 8, wherein the operational record data comprises a historical operational data of a user operating the second mobile device during a time period. ### Claim 10 (depends on 8) The disaster emergency rescue system of claim 8, wherein the action record data comprises a historical action data of a user carrying the second mobile device during a time period. ### Claim 11 A disaster emergency rescue communication method, comprising: executing a first application by a first mobile device to broadcast a positioning signal based on a first communication protocol; receiving the positioning signal by a second mobile device to activate a second application, originally in a suspended status or a not-running status, installed on the second mobile device; and the first mobile device communicating with the second application of the second mobile device via the first application after the second application is activated. ### Claim 12 (depends on 11) The method of claim 11, wherein the first mobile device communicates with the second application of the second mobile device via the first application and a mobile communication network. ### Claim 13 (depends on 11) The method of claim 11, wherein a step of executing the first application by the first mobile device to broadcast the positioning signal based on the first communication protocol further comprises: broadcasting a communication service signal, and periodically and alternately broadcasting the positioning signal and the communication service signal by the first mobile device. ### Claim 14 (depends on 13) The method of claim 13, wherein a step of the first mobile device communicating with the second application of the second mobile device via the first application after the second application is activated further comprises: enabling a communication service function based on a second communication protocol by the second mobile device; and returning a communication response signal to the first mobile device by the second mobile device after receiving the communication service signal so as to establish a communication connection between the second mobile device and the first mobile device. ### Claim 15 (depends on 14) The method of claim 14, wherein a step of returning the communication response signal to the first mobile device by the second mobile device after receiving the communication service signal so as to establish the communication connection between the second mobile device and the first mobile device further comprises: calculating a distance between the second mobile device and the first mobile device according to a strength of a returned signal of the second mobile device by the first mobile device and displaying the distance by the first application. ### Claim 16 (depends on 11) The method of claim 11, wherein a step of the first mobile device communicating with the second application of the second mobile device via the first application after the second application is activated further comprises: transmitting a user data to the first mobile by the second mobile device and displaying the user data via the first application by the first mobile device. ### Claim 17 (depends on 16) The method of claim 16, wherein the user data comprises a healthy data. ### Claim 18 (depends on 17) The method of claim 17, wherein the user data further comprises one or more of a personal data, an operational record data and an action record data. ### Claim 19 (depends on 18) The method of claim 18, wherein the operational record data comprises a historical operational data of a user operating the second mobile device during a time period. ### Claim 20 (depends on 18) The method of claim 18, wherein the action record data comprises a historical action data of a user carrying the second mobile device during a time period.
