Step 302: first terminal sends request message to server；Wherein, the instruction information of setting time range and N number of subregion is carried in the request message.

Specifically, above-mentioned server can be configured to receive and handle from any terminal or the terminal authenticated for obtaining the request message of satellite data, and can be configured to return to its requested satellite data to corresponding terminal.

For example, still being based on example communications system shown in FIG. 1, the functional module to receive and handle the request message for obtaining satellite data from any terminal or the terminal authenticated may be configured on server 101, and may be configured with use To return to the functional module of its requested satellite data to corresponding terminal.For example, server 101 can receive the request message that the terminal 102 for establishing communication connection with it is sent, and its requested satellite data can be returned to terminal 102.

Specifically, after server receives the request message that first terminal is sent by step 301, the request message can be parsed, and therefrom determine N number of subregion in the corresponding setting time range of satellite data needed for terminal and map.

In a kind of possible realization scene, server is after determining the corresponding setting time range of satellite data needed for terminal and N number of subregion, it can be according to historical satellite data, the corresponding satellite data of the N number of subregion is calculated within the scope of the setting time, to return to the response message for carrying within the scope of the setting time the corresponding satellite data of the N number of subregion to first terminal.

Specifically, above-mentioned historical satellite data can be server and obtain and store the satellite data that each satellite on server, in GPS is issued.

Since each satellite in GPS usually broadcasts respectively real-time satellite data according to the fixed cycle, thus, in some actual scenes, it may be configured with the GPS unit to receive satellite-signal on server, with the satellite data of real-time reception satellite broadcasting, it can be stored in the storage unit of server after reception, the processing unit of server is by reading the historical satellite data stored in storage unit, to execute above-mentioned calculating process.Wherein, also term of validity can be arranged to the satellite data at each moment of the history stored in server, to guarantee the accuracy of calculated result, for example term of validity can be set to one day etc.；

Alternatively, may be configured with the communication interface communicated with to the network equipment for being stored with satellite data in some actual scenes, on server, and then server directly can obtain historical satellite data from the above-mentioned network equipment by the communication interface.Specifically, server can be obtained using current time as the historical satellite data in an endpoint preset duration forward, and preset duration can be one day or longer period；Etc..

It further, can be according to the corresponding satellite data of subregion N number of within the scope of preset algorithm calculating setting time after server obtains historical satellite data.For example, server can be determined the distribution situation of each satellite by historical satellite data, and then the satellite data of each satellite within the scope of this following setting time by the subregion overhead is extrapolated to each subregion in this N number of subregion respectively.

Specifically, pass through the satellite data of each satellite in the subregion overhead within the scope of above-mentioned setting time, it may include mark (Identity, ID), orbital data and the star clock data of each satellite etc. having within the scope of the setting time by the subregion overhead；It can be seen that these above-mentioned satellite datas may be used to indicate terminal more effectively search of satellite signal.

In some actual scenes, for the considerations of improving user experience, server can also obtain historical satellite data according to the setting period, calculate within the scope of default time the corresponding satellite data of each subregion on map, and by calculated result storage into the storage unit of server, for example the corresponding satellite data of each subregion and each partition bindings can be stored, in turn, server is after the request message for receiving first terminal transmission, if it is determined that setting time range is located within the scope of default time, so server can directly read stored calculated result, return to first terminal, to accelerate response speed.

Specifically, it can also be stored with map datum on server, in turn, while satellite data needed for returning to it to first terminal, can return to the map datum with the subregion of satellite data binding.

By the above process, server can will return to the response message that carry the corresponding satellite data of N number of subregion within the scope of setting time to first terminal.In turn, the step 303 in process shown in Fig. 3 can be performed in first terminal.

Step 303: first terminal receives the response message that server returns.

Specifically, after first terminal receives the above-mentioned response message of server return, the corresponding satellite data of N number of subregion within the scope of the setting time needed for it can be got by the parsing to the response message.

Further, first terminal is got after the corresponding satellite data of N number of subregion within the scope of setting time, the above-mentioned satellite data that can be will acquire is stored into the storage unit of first terminal, and then within the scope of setting time, first terminal can read the corresponding satellite data of N number of subregion within the scope of the above-mentioned setting time stored in storage unit, use these satellite datas Search of satellite signal；It can be seen that, through the above way, first terminal can carry out satellite acquisition by following satellite data that server is extrapolated in advance based on what is got, the mode that more current poll searches star will be provided with targetedly, it is thus possible to avoid current poll from searching and search accurate satellite-signal caused by star, realizes the longer defect of positioning required time；

Especially first terminal do not have with the ability of base station communication or first terminal are offline etc. so that the GPS unit of first terminal is cannot get auxiliary positioning information in the case where, traditional poll searches star scheme will be so that first terminal needs to search about 32 Pseudo-Random Noise Code (pseudo random noise code, PRN) (it is equivalent to above-mentioned satellite-signal), and pass through above-mentioned process as shown in Figure 3, as long as first terminal is searched 4~5 PRN and can be accurately positioned, greatly shortened on the time.

Further, after the corresponding satellite data storage of N number of subregion is into the storage unit of first terminal within the scope of the setting time that first terminal will acquire, if detecting that second terminal and first terminal foundation have communication connection, so first terminal can be by the corresponding satellite data transmission of subregion N number of within the scope of above-mentioned setting time to second terminal, so that second terminal is able to use above-mentioned satellite data search of satellite signal within the scope of above-mentioned setting time.

Such as, it still is based on example communications system shown in FIG. 1, terminal 102 has been got by the above-mentioned communication process between server 101 after the corresponding satellite data of N number of subregion within the scope of setting time, due to detecting that terminal 103 and its have established communication connection, the so above-mentioned satellite data transmission that can be got of terminal 102 is to terminal 103, so that above-mentioned satellite data search of satellite signal can also be used in terminal 103 within the scope of setting time.

Specifically, terminal 103 is connected to after terminal 102, and can terminal 102 can first confirm to its transmitting satellite data；For example, terminal 102 can authenticate the legitimacy that terminal 103 is transmitted, the application will be not detailed this.

Specifically, second terminal can be is connected on first terminal by short-distance wireless communication technology, and short-distance wireless communication technology, which can be found in, to be described above, and specifically such as may include having bluetooth, Wi-Fi, infrared data transmission etc..

Further, second terminal, which specifically can be, has short-distance wireless communication function, without having the terminal of the function of being communicated with base station and/or the function of being communicated with server.Such as only bluetooth bracelet, Bluetooth watch with GPS unit, as wearable device, the reason for being limited to volume does not often have the function etc. of being communicated with base station.Such second terminal is when search of satellite signal carries out GPS positioning due to that can not directly obtain the auxiliary from base station or Internet Server, the time of search of satellite signal completion positioning is often longer (usually more than 30 seconds) when thus working independently, and user experience is bad；When especially this kind of second terminal is moved to a completely new geographic range, the time needed for the GPS unit search of satellite signal configured thereon completes positioning will be longer；

And pass through communication process provided by the above embodiments of the present application, the second terminal of the above-mentioned type can set up communication connection by short-distance wireless communication function and first terminal, and then after first terminal gets by the above-mentioned communication process between server the corresponding satellite data of N number of subregion within the scope of setting time, above-mentioned satellite data can be got indirectly by the communication connection established between first terminal, so as to when the first equipment of disengaging works independently, accessed satellite data, which can be used, purpose search of satellite signal, realize quickly positioning, promote user experience.

For example, in some actual scenes, first terminal specifically can be mobile phone, tablet computer, notebook etc., and second terminal specifically can be smartwatch, Intelligent bracelet, intelligent glasses etc. based on the associated description in figure 1 above, Fig. 2.
