What Is a Mobile Phone Tracking System?
Mobile phone positioning tracker is a personal remote positioning device composed of GPS and GSM / GPRS modules. It is a [1] smart size, high accuracy remote positioning device. Based on GPS satellites, it provides users with accurate and accurate position information under dynamic conditions. The personal remote positioning device transmits longitude and latitude coordinates to an authorized mobile phone.
- Mobile positioning refers to the acquisition of mobile phones or end users through specific positioning technologies.

- Support SMS and Internet query location information
- Can monitor without disturbing the person being tracked and track in real time
- Locate the holder by phone or SMS
- Precise positioning by pressing SOS button in emergency
- As long as there is a corresponding receiving device, it can intercept any call information and the communication process of the mobile phone. This is to use the mobile phone to transmit the speech signal to the mobile communication network, and then the mobile communication network will convert the speech signal into the electromagnetic spectrum and transmit it to the satellite via communication satellite radiation In the callee's telecommunication network, the callee's communication equipment receives wireless electromagnetic waves, and then converts them into speech signals to connect to the communication network. Therefore, mobile phone communication is an open electronic communication system. As long as there is a corresponding receiving device, it can intercept call information at any time, any place, and any person.

- This mobile positioning tracking software, what I want to suggest is that all your tracking needs are absolutely wonderful. I know you might be skeptical, but I'll give you this software down so you can decide for yourself whether it's worth a try:
- (1) This software program allows you to access basically all important communication data which is recorded in the phone. What kind of important communication data do you ask? It records, among them, phone, text and email data. With this information, you know that you can trust the owner of the phone.
- (2) If the call is to be tracked, the software is the perfect solution after positioning. It provides real-time (yes, you read it right) tracking via GPS, which means you will know the host just on the phone. Hey, who turned off the phone these days?
- (3) This software program is also very easy to access, and when you purchase it, they will give you an account on their website. All you have to do to access the data on all the target phones is to sit on your computer, log in to your account, everything will be waiting for you here. This is also where you will see your phone. I believe how easy it is, but this is really all mobile phones that need to be tracked!
- (4) The only complicated part you may encounter is installation. This is the only time you will actually contact the target by phone. However, the software is easy to install, and even the most technical challenges we can do in less than a few minutes. Don't worry about others finding the software; it's completely invisible to install! [2]
- The mobile phone positioning tracker system refers to a technology or service for obtaining the location information (latitude and longitude coordinates) of a mobile phone or an end user through a specific positioning technology, and marking the location of an object to be located on an electronic map.
- Mobile positioning classification
- The mobile phone positioning tracker system can be divided into two types according to the way of providing services: its own mobile phone positioning system and public positioning system. According to the different functions of the mobile phone, it can be divided into two types of positioning, SMS version mobile positioning and WAP version mobile positioning. Proper use of these positioning systems can provide a lot of convenience to life or work.
- By analyzing 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 now, 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.

- The GSM mobile communication network can realize the lcs service by adding a network node-mobile positioning center (mlc). Relevant interfaces introduced by the system are: service mobile positioning center smlc and bsc interface (lb), mobile positioning center gateway gmlc and gsm network business control function interface (lc) external lcs user and mobile positioning center mlc interface (le) Interface between mobile positioning center gateway and hlr (lh), interface between mobile positioning center gateway and msc / vlr (lg) interface between mobile positioning center and equivalent mobile positioning center (lp), interface between mobile positioning center and msc / vlr ls ) And positioning measurement unit lmu air interface (um).
- 1. Positioning measurement unit (lmu)
- Through wireless measurement, lmu can support multiple positioning methods. Measurements can be divided into two categories: (1) positioning measurement for one ms; (2) auxiliary measurement for all ms in a specific geographic area. Other information such as the initial value of lmu, time command can be set in advance, or provided through a mobile positioning center (smlc), lmu will provide all the positioning and auxiliary information obtained to the relevant smlc.
- lmu can be divided into two types: a and b. A type lmu is accessed through a standard gsm air interface, and a signaling connection is maintained with smlc controlling the lmu via bts and bsc. When the nss-based smlc is connected, a class lmu has the msc and vlr that serve it, and retains its registered information on the hlr. Class lmu has the only imsi and supports all gsm radio resources and mobility management functions. The network manager can assign a special imsi range to lmu, and assign a specific number in imsi to indicate the relevant smlc. Some numbers in imsi can be used as native code for a lmu in smlc. A type of lmu supports connection control and management functions, and can realize lcs signaling processing with smlc.
- It also supports call control functions, and can use a circuit-switched method to achieve signaling connection with smlc. To ensure that between lmu and smlc
- For mutual visits, lmu must be located in a cell belonging to the same bsc or msc. When smlc is based on nss, any type a lmu has registration information in hlr, which has no additional services (except point-to-point SMS and incoming and outgoing restriction services). At the same time, the registration information in hlr distinguishes the ms with lmu function from ordinary ms. All the data about lmu is managed by lmu and related smlc. Class b lmu can be accessed from the abis interface of bsc. It can be a separate network unit with some pseudo cell id numbers, or it can be integrated in or connected to bts. When smlc is based on bss mode, the signaling of class b lmu is transmitted via bsc; when smlc is based on nss mode, it is transmitted via bsc and msc.
- 2. Mobile positioning center gateway (gmlc)
- A plmn can have multiple gmls. gmlc is the first node for external lcs users to enter the gsm network. gmlc obtains routing information from hlr through the lh interface. After the authentication is passed, gmlc sends a positioning request to msc / vlr through the lg interface and receives the final positioning result.
- 3. Mobile positioning center (smlc)
- A plmn can include multiple smlcs. smlc manages all resources used for mobile phone positioning, and calculates the final positioning results and accuracy.
- There are usually two types of smlc: one is based on nss and supports the ls interface standard; the other is based on bss and supports the lb interface. The former transmits various mobile phone positioning signaling through the ls interface connected to msc / vlr; the latter transmits various mobile phone positioning signaling through the lb interface connected to bsc. These two smlcs use the lp interface when connecting with other smlcs. The functions of smlc and gmlc can be combined on the same physical node, or they can be distributed on multiple nodes. In the lcs service, when the cell broadcast center (cbc) is connected to bsc, smlc can use the existing broadcast function to broadcast auxiliary information through cbc. At this time smlc is equivalent to the user of cbc. [3]
