Mobile phone positioning refers to the cooperation of wireless terminals (mobile phones) and wireless networks to determine the actual location information (latitude and longitude coordinate data, including three-dimensional data) of mobile users, and send them to users through SMS, MMS, and voice, or provide some kind of information based on this. Value-added services. Location based service (LBS), also known as location based service (LBS), is to obtain the location information (latitude and longitude coordinates) of mobile terminal users through the network of telecom mobile operators (such as GSM network and CDMA network). It is a value-added service that provides corresponding services to users.
Mobile phone positioning is to use the cellular technology of the GSM mobile communication network to query location information. The GSM wireless communication network is constructed from many cells like bee cells. Each cell has its own number. The identification number can know the area where the phone is located. The mobile phone cell positioning technology is still being perfected. The accuracy of the urban area is roughly 200 meters, and the accuracy of the suburban area is roughly 1000 meters to 2000 meters. With the continuous development of mobile company technology, it is believed that the accuracy will be further improved to 50 meters. Inside. At the same time, the displayed landmark names are still being optimized. With further optimization, the landmarks will be more accurate.
The cellular positioning technology also belongs to the LBS base station positioning. This positioning method is commonly known as the ground positioning system, because it relies on the longitude and latitude information obtained by the operator's signal towers on the surface to determine the location of the terminal. All mobile phone cards can be accurately located as long as they are activated and can make and receive calls normally. The positioning ability is strong, and the positioning signal can effectively penetrate buildings, basements, tunnel traffic, etc. Each mobile phone card has a unique identification code, just like making a call, each number uniquely points to a fixed mobile phone, and LBS base station positioning can also effectively find a fixed number through the identification code The location of the mobile phone is displayed on the electronic map. This type of positioning technology is mandatory and widely used in some regulatory fields.

Location service, also known as mobile location service, is a value-added service that obtains the location information of mobile terminal users through the network of telecom mobile operators, and provides users with corresponding services under the support of the electronic map platform.

The mobile phone positioning system refers to the technology or service that obtains the position information (latitude and longitude coordinates) of the mobile phone or terminal user through a specific positioning technology, and marks the position of the positioned object on the electronic map.
The mobile phone positioning system is not necessarily the mobile phone GPS positioning. First of all, let's talk about the positioning technology. There are two positioning technologies, one is based on GPS positioning, and the other is based on the positioning of the base station of the mobile operating network. The GPS-based positioning method uses the GPS positioning module on the mobile phone to send its own position signal to the positioning background to realize the mobile phone positioning. Base station positioning is to use the distance measured by the base station to the mobile phone to determine the location of the mobile phone. The latter does not require the mobile phone to have GPS positioning capabilities, but the accuracy largely depends on the distribution of base stations and the size of the coverage area, and sometimes the error will exceed one kilometer. The former has higher positioning accuracy. In addition, there is a way to use Wifi to locate in a small area.
Mobile phone positioning systems can be divided into two types according to the way of providing services: self-owned mobile phone positioning systems and public positioning systems. According to the different functions of the mobile phone, it can be divided into two types of positioning, the SMS version of the mobile phone positioning and the WAP version of the mobile phone positioning. Reasonable use of these positioning systems can provide a lot of convenience to life or work.
By analyzing the mobile phone GPS and mobile phone positioning system, we can see the difference and connection between the two. Although mobile phone integrated GPS has been used, it is not yet popular. With the development of GPS technology and the improvement of mobile phone performance, mobile phone GPS and Mobile phone positioning system should become one of the basic functions of mobile phones.
