Description

Auxiliary global positioning method and mobile terminal

The present invention relates to the field of communications technologies, and in particular, to an assisted global positioning method and a mobile terminal. Background technique

Currently, location services have become one of the most common and basic functions in mobile terminals. In order to provide users with more convenient location services, various location service technologies are applied, such as Advanced Forward Link Trilateration (AFLT), Cell Identification Number (CELLID: Cell Identity), Time Difference of Arrival (TDOA). : Time Difference Of Arrival), Enhanced Observed Time Difference (OTTD), Observed Time Difference Of Arrival, etc.

In the area of location services, positioning speed and accuracy are two very important indicators that affect the user experience. Auxiliary global positioning technology has significantly improved these two indicators, especially in terms of positioning speed. Due to the comprehensive requirements for deployment cost, positioning accuracy, speed, etc., user-based assisted global positioning technology has become the most mainstream mobile positioning technology. Auxiliary global positioning technology is divided into user plane-based assisted global positioning technology and control plane-based assisted global positioning technology. User plane-based assisted global positioning technology is the most widely used in positioning navigation, including Open Mobile Alliance (OMA: Open Mobile). Alliance's Secure User Plan Location (SUPL) specification is the most widely used and representative.

The basic principle of the SUPL is that the service positioning module of the terminal sends the identification code of the location area where the mobile terminal currently resides to the auxiliary positioning server, and the auxiliary positioning server quickly returns the visible area of the terminal to the terminal according to the location area identification code of the terminal. The ephemeris, almanac, and Doppler, ionosphere and other auxiliary positioning data of the satellite used for positioning. This kind of assisted global positioning method On behalf of the terminal, the above-mentioned auxiliary positioning data is obtained by demodulating the slow satellite signal, thereby speeding up the positioning speed.

Currently, there are three types of positioning methods commonly used in assisting global positioning technology:

1. The mobile terminal acquires the positioning information of the auxiliary positioning server through the cellular network. When the mobile terminal supports the cellular network to access the Internet, the service positioning module in the mobile terminal sends the positioning request information of the target terminal to the auxiliary positioning server, and the auxiliary positioning server locates the target terminal, and passes the obtained mobile terminal location information. The cellular network is sent to the service location module to enable assisted global positioning through the cellular network. At present, the cellular network has more users and supports more types of mobile phones. Common cellular networks include GSM network, CDMA network, 3G network, FDMA, TDM A, PDC, TACS, AMPS, and the like. Due to the popularity of cellular networks, the use of cellular networks for assisted global positioning is high. However, when the mobile terminal disables the cellular network or the mobile terminal is not plugged in, the mobile terminal can access the network using WIFI (wireless-fidelity), but the mobile terminal capable of network interconnection cannot achieve the assisted global positioning. This positioning method requires the mobile terminal to have the function of accessing through the cellular network, but in some cases, the mobile terminal does not satisfy the above functions, such as pure WIFI PAD. This design, which relies entirely on cellular networks to obtain assisted location information, limits the range of mobile terminals that assist in global positioning.

2. The mobile terminal obtains the positioning information of the auxiliary positioning server through the WIFI. WIFI is a short-range wireless transmission technology that can be connected to the WIFI connection within a certain range. When the mobile terminal supports the WIFI to access the Internet, the service positioning module in the mobile terminal sends the positioning request information of the target terminal to the auxiliary positioning server, and the auxiliary positioning server locates the target terminal, and the location information of the obtained mobile terminal is passed through the WIFI. The mode is sent to the service positioning module. Because WIFI is a free wireless LAN, it can support Internet access within hundreds of feet and has a wide application prospect. However, at present, there are fewer auxiliary positioning servers supporting WIFI positioning, and few equipment suppliers supporting WIFI positioning. Due to the limitations of WIFI applications, When relying entirely on WIFI for assisted global positioning, the rate of success in the current state is lower. Third, through the cellular network on the mobile terminal or mobile Internet downloading auxiliary positioning program such as WIFI, to obtain auxiliary positioning information. The method of assisting global positioning is to assist in global positioning by downloading auxiliary positioning information. Currently, this service for downloading assisted location information is provided by a dedicated service provider and requires payment to download. Moreover, the accuracy of such downloaded data is not very high, and it is not real-time positioning data, thereby contributing to poor performance of global positioning.

In summary, based on the prior art, the terminal performs the assisted global positioning according to the default mobile internet as the bearer network, and in the case that the terminal also has other mobile internet networks, other mobile internet cannot be selected as the bearer network for the positioning information. This limits the range of applications for the terminal to assist in global positioning. Summary of the invention
