Embodiment

This routine transceiver communication module can be GSM module, CDMA module or 3G module, is example with the GSM module, its system block diagram such as Fig. 1.

At first the transceiver communication module is connected with processor module, the GPS module is connected with processor module, memory module is connected with processor module, the audio video processor module is connected with processor module, display module is connected with processor module, display module and audio video processor module connect to form a kind of equipment based on the shift position service of the present invention, wherein processor module comprises processor platform and the buffer memory (as SDRAM, DDR II etc.) of supporting real-time system, mainly finishes the function such as program running, system's control of equipment; Memory module comprises NANDFLASH memory module, SD card etc., can be used to storing multimedia or map datum etc.; The transceiver communication module is responsible for finishing the information interaction with the communications service provider, to realize that normal demand for services is submitted to and information on services biography down, is the GSM module here; The GPS module is finished obtaining of GPS position data, and can cooperate the respective electronic map to realize functions such as navigation; Display unit is the LCD LCDs, can display image, the function that shows of video playback; The encoding and decoding of audio/video multimedia file are responsible in the audio frequency and video unit, and this part can be independent unit, also can be integrated in the processor module.

Wherein, the GPS module links to each other with the different UART interfaces of processor module by the UART interface of himself respectively with the GSM module, realizes the mutual and transmission of data respectively by the UART port set of this pairing.The GSP module is by the UART mouth, standard N MEA (National Marine Electronics Association) data are sent into processor module, these data comprise the data such as original latitude and longitude information, elevation information above sea level and 3D locating information that the GPS module receives, by the GPS search engine software and the corresponding map datum of processor module operation, can finish the navigation feature of terminal.The GSM module is by the UART interface, control command and the data message of accepting the processor module transmission (send order such as information, and send the state information (comprising the note data that receives, signal strength data etc.) of various information datas that the GSM module receives and GSM module itself to processor module note instruction to be sent etc.).

The real-time, interactive of gps data and GSM data is keys of this equipment.The position data that GPS receives, treated device module is delivered to the GSM module, as raw position data and reference data, add corresponding order or request instruction (as near the inquiry of Chinese-style restaurant), be wirelessly transmitted to communications service provider's server platform (generally being the service-specific backstage of each wireless carriers) by the GSM module, platform is according to corresponding instruction, near the corresponding request items of search raw position data, and Search Results (as: target latitude and longitude information) passed through short message, audio frequency or other forms of transfer of data are returned this equipment, program for this equipment is handled (as: according to target information, calculating corresponding track route).When GPS module received signal is not enough, this equipment also can receive supplementary by the GSM module and finish navigation feature, this equipment and the mutual signal strength signal intensity in base station can be caught in a plurality of wireless base stations, by the difference of signal strength signal intensity and the position relation of each base station, communications service provider's server platform can calculate the position of equipment, and extract corresponding longitude and latitude data, be sent to this equipment GSM module, be transferred to processor module again, processor module can be finished the navigation feature under no GPS or the weak gps signal situation by navigation engine software and map datum on the equipment.

The equipment based on the shift position service of this example can receive gps signal and obtain positional information, and can cooperate the respective electronic map to realize functions such as navigation; Can realize communication information transmission-receiving function, include but not limited to SMS (Short MessagingService) information transmit-receive.Can send the SMS information of specified format, the information of equipment position and other given contents is provided to the communications service provider by near the communication base station equipment; And can receive the information on services that the communications service provider returns, by the information that receives is analysed, realize corresponding service function, comprise cooperating corresponding electronic chart to realize navigation, receive and move the service for life information that service provider provides, functions such as daily commercial matters information.Equipment can show and play relevant picture, audio frequency and video program and show on the lcd screen of equipment.

This example has dual mode to realize the LBS service, and the main distinction is the obtain manner of positional information, and in different application scenarios, two kinds of mode of operations are well complementary, can give full play to its LBS service function.

First kind, utilize the GPS module to obtain positional information, can realize the navigation of off line form.When needing other location information service (as: navigation requests or near hotel information demand), equipment sends request instructions by transceiver communication module (as GSM module, CDMA module or 3G module); After communications service provider's server platform receives request command, analyze real needs, and this equipment of giving sends corresponding information on services (as positional information, near hotel information); Equipment receives information on services by the transceiver communication module, sends into processor module and handles.Processor module analyzes the content of information on services, and the control corresponding module is finished appointed function (as the show navigator path or show corresponding hotel information).The advantage of this kind mode of operation is the positioning accuracy height, can realize real-time navigation, does not need to increase more mobile communication expense.When the bad environment of receiving satellite signal effect such as being in indoor, tunnel, shortcoming can't use.

Second kind, utilize the telco provider mobile base station to obtain positional information, and send request instructions by the transceiver communication module, after communications service provider's server platform receives request command, analyze real needs, and send corresponding information on services for this equipment, equipment receives information on services by the transceiver communication module, sends into processor module and handles.Processor module analyzes the content of information on services, and the control corresponding module is finished appointed function (as the show navigator path or show corresponding hotel information).The advantage of this kind mode of operation is to make full use of the good coverage rate of telecom dealer mobile network, realizes LBS service as far as possible on a large scale.At some the position being spent requirement clearly is not that very high LBS information service occasion very is very useful.Shortcoming is positioning accuracy poor (main cause is that the mobile network base station is the basis of location, and its precision is limit by the layout of base station), real-time navigation ability.
