Abstract

Embodiments of the application provide a distress information sending method and system. By setting automatic switching of various communication means, a user may be rescued in time. The method includes a terminal device obtains first distress information, where the first distress information includes at least one of adverse sign information or positioning information of a user. The terminal device selects a first communication network from a plurality of communication networks in a preset sequence. When the terminal device can be connected to the rescue processing device by using the first communication network, the terminal device sends the first distress information to the rescue processing device by using the first communication network. Alternatively, when the terminal device cannot be connected to the rescue processing device by using the first communication network, the terminal device reselects a new first communication network from the plurality of communication networks in the preset sequence.

First claim

1 . A distress information sending method, wherein the method comprises:
obtaining, by a terminal device, first distress information, wherein the first distress information comprises at least one of adverse sign information or positioning information of a user; selecting, by the terminal device, a first communication network from a plurality of communication networks in a preset sequence, wherein the first communication network is any one of a short-range connection network, a cellular network, a satellite network, and a communication network between remote devices, and the communication network between remote devices is a point-to-point communication network established by the terminal device and a rescue processing device by using a preset frequency resource; and when the terminal device can be connected to the rescue processing device by using the first communication network, sending, by the terminal device, the first distress information to the rescue processing device by using the first communication network; or when the terminal device cannot be connected to the rescue processing device by using the first communication network, re-selecting, by the terminal device, a new first communication network from the plurality of communication networks in the preset sequence.

2 . The method according to claim 1 , wherein before the obtaining, by a terminal device, first distress information, the method further comprises:
receiving, by the terminal device, first pre-distress information sent from a wearable smart device, wherein the first pre-distress information is generated based on the adverse sign information when the wearable smart device detects an abnormality in a sign of the user; and the obtaining, by a terminal device, first distress information comprises: generating, by the terminal device, the first distress information based on the first pre-distress information.

3 . The method according to claim 2 , wherein the generating, by the terminal device, the first distress information based on the first pre-distress information comprises:
sorting, by the terminal device, distress content in the first pre-distress information based on an importance degree; and processing distress content corresponding to a sequence number before a preset threshold value, to obtain the first distress information.

4 . The method according to claim 1 wherein the preset sequence from front to back is: the short-range connection network, the cellular network, the satellite network, and the communication network between remote devices.

5 . The method according to claim 4 , wherein selecting, by the terminal device, the first communication network from the plurality of communication networks in the preset sequence; and when the terminal device can be connected to the rescue processing device by using the first communication network, sending, by the terminal device, the first distress information to the rescue processing device by using the first communication network; or when the terminal device cannot be connected to the rescue processing device by using the first communication network, the re-selecting, by the terminal device, a new first communication network from the plurality of communication networks in the preset sequence comprises:
selecting, by the terminal device, the short-range connection network as the first communication network from the plurality of communication networks in the preset sequence, and determining whether the terminal device can be connected to the rescue processing device by using the short-range connection network; when the terminal device can be connected to the rescue processing device by using the short-range connection network, sending, by the terminal device, the first distress information to the rescue processing device by using the short-range connection network; or when the terminal device cannot be connected to the rescue processing device by using the short-range connection network, selecting the cellular network as the first communication network, and determining whether the terminal device can be connected to the rescue processing device by using the cellular network; and when the terminal device can be connected to the rescue processing device by using the cellular network, sending, by the terminal device, the first distress information to the rescue processing device by using the cellular network; or when the terminal device cannot be connected to the rescue processing device by using the cellular network, selecting the satellite network as the first communication network, and determining whether the terminal device can be connected to the rescue processing device by using the satellite network; and when the terminal device can be connected to the rescue processing device by using the satellite network, sending, by the terminal device, the first distress information to the rescue processing device by using the satellite network; or when the terminal device cannot be connected to the rescue processing device by using the satellite network, selecting the communication network between remote devices as the first communication network, and determining whether the terminal device can be connected to the rescue processing device by using the communication network between remote devices; and when the terminal device can be connected to the rescue processing device by using the communication network between remote devices, sending, by the terminal device, the first distress information to the rescue processing device by using the communication network between remote devices; or when the terminal device cannot be connected to the rescue processing device by using the communication network between remote devices, re-selecting, by the terminal device, a new first communication network in the preset sequence.

6 . The method according to claim 5 , wherein the determining whether the terminal device can be connected to the rescue processing device by using the communication network between remote devices comprises:
initiating, by the terminal device, scanning of a communication signal between the remote devices, and when the communication signal between the remote devices is obtained through scanning, establishing, by the terminal device, a connection with a peer device that sends the signal of the communication between the remote devices; sending, by the terminal device, an inquiry instruction to the peer device, wherein the inquiry instruction is used for inquiring whether the peer device can be connected to the rescue processing device, and the inquiry instruction comprises an address of the rescue processing device; and in response to an inquiry result sent by the peer device, when the peer device can be connected to the rescue processing device, determining that the terminal device can be connected to the rescue processing device by using the communication network between remote devices, when the peer device cannot be connected to the rescue processing device, determining that the terminal device cannot be connected to the rescue processing device by using the communication network between remote devices.

7 . The method according to claim 5 , wherein the determining whether the terminal device can be connected to the rescue processing device by using the cellular network comprises:
determining, by the terminal device, whether the terminal device can be connected to the rescue processing device by using a subscriber identity identification (SIM) card operator cellular network in the cellular network; and when the terminal device can be connected to the rescue processing device by using the SIM card operator cellular network in the cellular network, determining that the first communication network is the SIM card operator cellular network in the cellular networ
