The present application will be described in detail with reference to specific examples.
In one embodiment, as shown in fig. 1, a method for locating an emergency call is proposed, which may be implemented by means of a computer program and which may be run on a locating device for emergency calls based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application. The location device of the emergency call may be a user terminal, including but not limited to: personal computers, tablet computers, handheld devices, in-vehicle devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and the like. The terminal devices in different networks may be called different names, for example: user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user equipment, cellular telephone, cordless telephone, terminal equipment in a 5G network or future evolution network, and the like.
Specifically, the emergency call positioning method includes:
s101: and receiving a triggering instruction of the emergency call, and acquiring the height information of the current position acquired by the barometer.
The execution main body of the embodiment is a user terminal, and the emergency call refers to that a user uses the user terminal to give an alarm or ask for help when encountering an emergency.
The triggering instruction refers to a signal for triggering the user terminal to perform positioning when the user performs an emergency call operation, for example, taking a smart phone as an example, when the user dials the alarm number 110 or the emergency number 120 to perform an emergency call by using the smart phone, the input alarm number 110 or the emergency number 120 is a triggering instruction for triggering the smart phone to position the current location.
Specifically, when the trigger instruction is received, the current position of the user terminal is located. Firstly, altitude information, longitude information and latitude information of the current position are measured. Wherein, the height information of the current position is measured by the barometer.
The barometer is a device that converts atmospheric pressure into the altitude information by measuring changes in atmospheric pressure and according to a correspondence between atmospheric pressure and altitude. The height information refers to the vertical distance that the current position is higher than the average sea level, namely the altitude. Wherein, the corresponding relation between the atmospheric pressure and the altitude is as follows: the higher the altitude, the lower the atmospheric pressure; the lower the altitude, the greater the atmospheric pressure.
The barometer may be a component of the user terminal, or may be a device connected to the user terminal for measuring height information.
S102: and acquiring longitude information and latitude information of the current position acquired by the GPS module.
The GPS module is an integrated circuit that integrates a Radio Frequency (RF) chip, a baseband chip, a Central Processing Unit (CPU), and related peripheral circuits in the user terminal.
Specifically, the GPS module can perform real-time positioning in a global range by using a GPS positioning satellite, thereby measuring longitude information and latitude information of a current position. Wherein, connecting a point on the earth surface with the south and north poles, the included angle between the connecting line and the plane of the 0 degree longitude is the longitude information of the point. The latitude information refers to the included angle between the ground normal of one point on the earth surface and the equatorial plane.
S103: generating target address information based on the altitude information, the longitude information, and the latitude information.
Specifically, for an indoor scene, the altitude information, the longitude information, and the latitude information are converted to generate target address information in a preset format, where the preset format includes an address format of a street where the target address information is located and an address format of a floor where the target address information is located.
The longitude information and the latitude information can determine address information of a street where the current street is located, and the altitude information can determine address information of a floor where the current street is located.
For example, if the longitude information of the current location is 116.411384 ° and the latitude information is 39.919832 °, it can be determined that the street information of the current location is the lane 9 of the ordinary temple in the eastern city of beijing. The height information of the current position is 13m, and taking the height of each floor as 2.5m as an example, the floor information of the current position can be determined to be six floors.
Optionally, for an outdoor scene, the altitude information is altitude data of 2.5m or less, the address information of the current street may be determined according to the longitude information and the latitude information, and the address information of the current street is the target address information.
S104: and reporting the target address information to a gateway mobile location center so that the gateway mobile location center carries out positioning based on the target address information.
The process of reporting the target address information to the gateway mobile location center may be: forwarding the target address information to the Gateway Mobile Location Center (GMLC) through a Serving Mobile Location Center (SMLC). In this embodiment, the user terminal accesses the public land mobile network, thereby reporting the destination address information.
Specifically, the SMLC converts target address information generated by the user terminal into network transmission data based on a long term evolution positioning protocol (LPP) by using the 4th generation mobile communication technology (4G), and transmits the network transmission data to the GMLC. The LPP protocol supports location services (LCS) in a wireless network (e.g., 4G) based on Long Term Evolution (LTE) technology as defined by the 3rd Generation Partnership Project (3 GPP).
Optionally, the SMLC converts the destination address information generated by the user terminal into network transmission data by using a 4G LPPe-based protocol. The LPPe protocol is an extension protocol of the LPP protocol.
As shown in fig. 2, an exemplary schematic diagram of information reporting is shown, where, for example, a smart phone is used, after obtaining altitude information, longitude information, and latitude information, the smart phone 201 generates target address information, and sends the address information to a serving mobile location center 202; the service mobile location center 202 converts the target address information into network transmission data and sends the network transmission data to the gateway mobile location center 203; the gateway mobile location center 203 reads the network transmission data to obtain the target address information, and determines the current location of the user terminal based on the target address information.
In the embodiment of the application, the accurate altitude information can be acquired through the barometer, which is more accurate than the altitude information acquired through the GPS module, and meanwhile, the accurate longitude information and latitude information can be acquired through the GPS module, so that the location of the emergency call can be accurately located, and after the location is directly reported to the gateway mobile location center, the gateway mobile location center can also accurately locate the location of the emergency call.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for locating an emergency call according to another embodiment of the present application. Specifically, the method comprises the following steps:

See S101 for details, which are not described herein.
S202: and acquiring longitude information and latitude information of the current position acquired by the GPS module.

S203: and acquiring a map coordinate system in the electronic map.
The electronic map refers to a map that is digitally stored and referred to using computer technology.
Specifically, the user terminal may locally store the electronic map, and read the stored electronic map during positioning, so as to determine a map coordinate system in the electronic map.
Optionally, the user terminal may download the electronic map on the internet, determine a map coordinate system of the electronic map, select a suitable map coordinate system from different map coordinate systems, and download the electronic map corresponding to the suitable map coordinate system.
The map coordinate system refers to a coordinate system used by the electronic map to define the position of the earth surface. The map Coordinate System includes World Geodetic System-1984 (WGS-84 Coordinate System), BD09 Coordinate System, GCJ02 Coordinate System, and Chinese Geodetic Coordinate System 2000 (CGCS 2000) in 1984.
S204: and calculating the altitude information, the longitude information and the latitude information according to a conversion algorithm of the map coordinate system and the GPS coordinate system to generate the target address information.
Due to incompatibility between map coordinate systems, when target address information is determined based on the altitude information, the longitude information, and the latitude information, the target address position may be shifted. Therefore, when the altitude information, the longitude information, and the latitude information are converted to generate target address information in a preset format, the altitude information, the longitude information, and the latitude information are converted to coordinate information in the map coordinate system.
S205: and reporting the target address information to a gateway mobile location center so that the gateway mobile location center carries out positioning based on the target address information.
See S104 for details, which are not described herein.

The Public Safety Answering Point (PSAP) address can be determined by the gateway mobile location center based on the target address information, wherein the PSAP address is closest to the location of the user terminal. The user terminal and the public safety answering point can establish an emergency session link through a gateway mobile location center.
The process of reporting the target address information to the gateway mobile location center may be: forwarding the target address information to the Gateway Mobile Location Center (GMLC) through a Location Management Function (LMF).
Specifically, a Location Management Function (LMF) entity converts target address information generated by a user terminal into network transmission data by using the 5th generation mobile communication technology (5G) based on a long term evolution location protocol (LPP), and sends the network transmission data to a GMLC, and then the GMLC sends the network transmission data to a PASP.
Optionally, the LMF entity converts the target address information generated by the user terminal into network transmission data by using a 5G LPPe-based protocol. The LPPe protocol is an extension protocol of the LPP protocol.
As shown in fig. 4, an exemplary schematic diagram of information reporting is shown, taking a smart phone as an example, after obtaining altitude information, longitude information, and latitude information, a smart phone 401 generates target address information, and sends the address information to a positioning management function entity 402; the positioning management functional entity 402 converts the target address information into network transmission data, and sends the network transmission data to the gateway mobile location center 403; the gateway mobile location center 403 forwards the network transmission data to the public safety answering point 404; the public safety answering point 404 reads the network transmission data to obtain the destination address information, and determines the current location of the user terminal based on the destination address information.
In the embodiment of the application, the accurate altitude information can be acquired through the barometer, which is more accurate than the altitude information acquired through the GPS module, and meanwhile, the accurate longitude information and latitude information can be acquired through the GPS module, so that the location of the emergency call can be accurately located, and after the location is directly reported to the gateway mobile location center, the gateway mobile location center can also accurately locate the location of the emergency call.
