The 120 emergency telephone is the first emergency mode to be selected after the health of people is threatened. For medical institutions, how to quickly find the position of a patient and dispatch emergency vehicles to go to the position of a person seeking help in time for rescue is an important ring for ensuring the treatment efficiency and health loss of healthy life.
From the time that a caller initiates a call for help, the dispatcher accepts the call for help, to the time that the dispatcher dispatches a proper ambulance to go to first aid, the medical first aid is mainly focused on 'striving for minutes and seconds', and first aid patients needing rescue are found in the shortest time. For the active positioning of the patient, on one hand, the patient can dictate the address and the time for the dispatcher to input the address can be saved; on the other hand, the probability of misassignment of the vehicle due to address recording errors can be greatly reduced. Therefore, 120 emergency location becomes an important component of internet + pre-hospital emergency as a core link of 'capturing seconds for minutes'. Each city emergency center hopes to automatically acquire the position information of the user who dials 120 mobile phones through the project so as to save the emergency scheduling time.
At present, two existing positioning methods exist, one is a mode of dictating by an alarm person and recording by an operator, a large amount of confirmation time is generated in the communication, theory and registration, address recording errors are easily generated in dictation or recording, and the probability of vehicle misdispatch is increased; the second is to add other data or mode assistance, but is cost-limited and cannot achieve coverage of location capability in a full jurisdiction. Therefore, the 120 first-aid center needs to be connected with a brand-new, high-timeliness and low-cost positioning mode, the first-aid efficiency is improved, and the limitation of 120 first-aid can be overcome by the signaling acquisition technology based on mobile phone positioning.
