This application is a National Stage of International Application No. PCT/CN2014/073060, filed on Mar. 7, 2014, which is hereby incorporated by reference in its entirety.
Embodiments of the present invention relate to communications technologies, and in particular, to a method and an apparatus for sharing data between positioning devices.
With development of mobile technologies, various positioning devices applied to vehicles appear. Common positioning devices include a mobile phone and a vehicle terminal that have a positioning function.
A user enables a positioning function by using an application layer user interface of a positioning device. An operating system in the positioning device invokes a global positioning system (GPS) module according to a command delivered by the application layer user interface, so that the GPS module in an enabled state communicates with a satellite and obtains auxiliary data and original geographical location information of a vehicle that are sent by the satellite. GPS software in the operating system processes the auxiliary data and the original geographical location information of the vehicle, to obtain precise latitude and longitude information of a location of the vehicle. The auxiliary data is a group of data about the satellite and is used to calibrate the original geographical location information of the vehicle, so as to obtain the latitude and longitude information.
In the prior art, if no auxiliary data is stored in a positioning device, or if auxiliary data is stored in a positioning device but the stored auxiliary data is lost or expires, the positioning device needs to communicate with a satellite to acquire the auxiliary data, and a process of acquiring the auxiliary data needs to consume time. As a result, a positioning speed of the positioning device is relatively low.

It should be understood that although the embodiments of the present invention may describe various positioning devices by using terms such as first and second, the positioning devices should not be limited to these terms. These terms are merely used to distinguish the positioning devices from one another. For example, a first positioning device may be referred to as a second positioning device, and similarly, the second positioning device may be referred to as the first positioning device without departing from a scope of the embodiments of the present invention.
Step S101: A first positioning device acquires auxiliary data from a positioning server, where the auxiliary data is used by the first positioning device to perform positioning by combining original geographical location information corresponding to the first positioning device.
The first positioning device may be any device that can perform positioning, for example, may be a mobile terminal such as a mobile phone or a vehicle terminal, which is not limited in this embodiment of the present invention. The acquiring, by a first positioning device, auxiliary data from a positioning server such as a satellite is specifically: sending, by the first positioning device, an auxiliary data acquiring request to the satellite, and returning, by the satellite, the auxiliary data to the first positioning device. The auxiliary data is a group of data related to the satellite and is used by the first positioning device to perform positioning by combining original geographical location information corresponding to the first positioning device. Specifically, the first positioning device calibrates the original geographical location information corresponding to the first positioning device by using the auxiliary data, so as to obtain latitude and longitude information corresponding to a geographical location of the first positioning device.
Step S102: The first positioning device sends the auxiliary data to a second positioning device, so that the second positioning device performs positioning according to the auxiliary data and original geographical location information that corresponds to the second positioning device, where the second positioning device and the first positioning device are located in a same local area network.
The second positioning device may be any device that can perform positioning, for example, may be a mobile terminal such as a mobile phone or a vehicle terminal, which is not limited in this embodiment of the present invention. The first positioning device and the second positioning device are located in the same local area network, for example, in a same vehicle. The first positioning device sends the auxiliary data to the second positioning device in a wireless transmission manner or in a wired transmission manner, so that the second positioning device calibrates the original geographical location information corresponding to the second positioning device by using the auxiliary data, so as to obtain latitude and longitude information corresponding to a geographical location of the second positioning device.
In this embodiment of the present invention, auxiliary data is shared between positioning devices, so that the positioning device directly performs positioning by using the shared auxiliary data instead of performing positioning by communicating with a satellite to acquire the same auxiliary data, thereby reducing a time consumed as the positioning device communicates with the satellite to acquire the auxiliary data, and increasing a positioning speed of the positioning device.
Based on the foregoing embodiment, the acquiring, by a first positioning device, auxiliary data from a positioning server includes: acquiring, by the first positioning device, the auxiliary data from the positioning server, and parsing the auxiliary data, where the auxiliary data includes one or a combination of several of the following data: an ephemeris, an almanac, a time, and status data.
The parsing, by the first positioning device, the auxiliary data acquired from the positioning server is specifically performed by using a fireware chip in the first positioning device, where the parsed auxiliary data includes an ephemeris, an almanac, a time, and status data. The ephemeris, the almanac, the time, and the status data that are included in the auxiliary data are an ephemeris, an almanac, a time, and status data that corresponds to status information of a satellite at a moment when the satellite sends the auxiliary data, where the ephemeris, the almanac, the time, and the status data are recorded in the satellite at the auxiliary data sending moment.

After the first positioning device sends the auxiliary data to the second positioning device, the second positioning device first stores the auxiliary data in the local memory and sets the flag bit, to represent that the auxiliary data is already locally stored; and when performing the positioning operation, the second positioning device receives the original geographical location information that is sent by the satellite and that is used when the second positioning device performs the positioning operation, and calibrates the original geographical location information corresponding to the second positioning device by using the locally stored auxiliary data, instead of acquiring the same auxiliary data from the satellite, so as to obtain accurate latitude and longitude information.
In this embodiment of the present invention, a flag bit is set when a positioning device receives auxiliary data, so that the positioning device determines, according to the flag bit, whether the shared auxiliary data is locally stored, thereby reducing a time consumed as the positioning device communicates with the satellite to acquire the auxiliary data, and improving a positioning speed of the positioning device.
