Mobile phone positioning:
Principle:
Mobile phone positioning refers to determining the actual location information (latitude and longitude coordinate data, including three-dimensional data) of mobile users through the cooperation of wireless terminals (mobile phones) and wireless networks, and sending it to users through SMS, MMS and voice or providing some value-added services based on this.
It is a value-added service that provides users with corresponding services through the network of telecom mobile operators and with the support of electronic map platform.
Mobile phone positioning is to use the cellular technology of GSM mobile communication network to query the location information, and the area where the mobile phone is located can be known through the identification number of the cell where the mobile phone is located.
Cellular positioning technology belongs to LBS base station positioning, commonly known as ground positioning system, because it depends on the latitude and longitude information obtained by the operator's signal towers distributed on the ground to determine the position of the terminal.
Mobile phone system: it is a computer program that manages and controls computer software and hardware resources, and it is the most basic system software that runs directly on "bare metal". Any other software must be supported by the operating system to run.
Main uses:
Operating system is the interface between users and computers, and also the interface between computer hardware and other software.
Manage the hardware, software and data resources of the computer system, control the program running, improve the man-machine interface and provide support for other application software.
Let all the resources of the computer system play their roles to the maximum, provide various forms of user interfaces, and let users have a good working environment.
The operating system manages computer hardware resources and allocates resources according to the resource requests of application programs.
