Description
Technical Field
The invention relates to the technical field of communication positioning, in particular to a short message alarm positioning method and device.
Background
At present, the short message alarming positioning is an emergency alarming service based on the position of a mobile telephone signal base station, when an emergency situation is met, a user can initiate an alarm to an alarm receiving center, and the alarm receiving center provides general azimuth information of alarming personnel for rescue personnel through position information provided by the alarming personnel. The user can directly edit a short message: "I am on the XX street in XX district of XX, XX province, meet an emergency, please rescue-! And sending the short message to a special number provided by the alarm receiving center. However, sometimes, the alarm personnel may not know the position of the alarm personnel or the alarm personnel may not accurately transmit the position of the alarm personnel to the alarm receiving center, and the alarm receiving center can estimate the approximate method of the alarm personnel by calculating the position of the base station at this time, which comprises the following specific processes: after receiving the short message sent by the alarm personnel, the alarm receiving center starts to search the nearest base station. In general, a base station of a mobile phone has a certain coverage area, and if the location of a user cannot be determined, a police receiving center can continuously try to find other base stations. Once the nearest base station is found, the alarm receiving center calculates the distance between the base station and the user to infer the approximate location of the user. In order to improve the accuracy of the positioning of the sms alert, some geographic information system technologies and algorithms, such as DILATED RECTANGLE of Intersection (RRI) algorithm, maximum likelihood estimation, etc., are generally used, and these algorithms can help the alert receiving center calculate the distance between the base station and the user more accurately.
However, the accuracy and speed of the estimating the position of the alarm person based on the base station are affected by various factors, such as the coverage of the base station, the mobile phone setting of the user, the density of the base station, etc., so that in practical application, errors may occur. In addition, due to technical limitations, the current positioning method of estimating the azimuth of the alarm personnel by the base station generally only provides rough azimuth information of the alarm personnel, and cannot accurately reach a specific position point.
Therefore, the invention provides a short message alarm positioning method and device.
