A mobile terminal with emergency SOS function consists of setting module, storage unit, emergency SOS control module and SOS execution module. It is featured as not requiring to add any more hardware and utilizing normal telephone dialing operation and information receiving-transmitting operation of existed communication terminal.

Novel vision monitoring, screening, and testing tools and help-seeking enablers that may be used individually as or in combination with other vision monitoring and screening testing systems that improves patients' ability to recognize the onset and progression of visual changes over time. Patients' ability to identify acute or chronic visual conditions on their own may drive earlier help-seeking behavior by the patient, enable earlier clinical diagnosis by an eye care specialist, and therefore resulting in earlier treatment and reduced likelihood of severe vision loss.

The invention relates to an emergency help-seeking, risk early warning and one-touch SOS platform based on a mobile terminal. The platform includes a daily emergency help-seeking module for a help seeker to send help-seeking information to other users through the platform and acquire response from the other users through the platform to establish a one-to-one response session between the help seeker and the responding users; an early warning information transceiver module for releasing, enquiring, receiving and communicating with risk information and establishing a many-to-many session among users concerned about the risk information; and a risk emergency-SOS module for a user to send risk SOS information to a preset contact group with one click for emergency response and emergency-SOS when encountering an extremely risky event. The scheme of the invention allows emergency help-seeking to be extended from one-way help seeking to two-way interaction and supports that the user of the system to release help-seeking information to seek help, and meanwhile, the users can provide rescue for the help seeker and also can allow the user to know the risk in advance so as to make risk prevention and response measures in advance.

The invention provides a fountain code-based collaboration multicast method. The method comprises the following steps that: 1) a base station sends out encoded symbols formed by encoding a data packet by fountain codes, and finishes sending the data in the round after receiving correctly decoded feedback of all users; 2) after finishing receiving the data, the users under a good channel condition intercept help seeking signals of other users; when receiving the help seeking signals, the users participate in collaboration; and when receiving the correctly received feedback of the users collaborated with the user under the good channel condition, the users stop collaborating; and 3) the users who have not finished receiving the data intercept correctly received feedback signals of remaining users, and judge whether to send a help seeking signal according to the signal intensity of the feedback signals. According to the method, reliable transmission which does not need to be retransmitted is provided by using the fountain codes; and simultaneously system capacity is improved by combining a collaboration mode. According to the fountain code-based collaboration multicast method, collaboration participation and exit conditions of the users are also given; energy consumption of user collaboration is reduced; and the service life of network is prolonged.
