Description

Air navigation aid and system based on cordless communication network

Technical field

The present invention relates to remote wireless monitoring technology, LBS network positions technology, GPS terminal positioning technology, wireless communication technology, the network communications technology, TTS technology, GIS technology, and the various software technology, specifically be meant interactive navigation commander method and system based on cordless communication network.Belong to areas of information technology.

Background technology

At present, known air navigation aid and system are meant: be the new technique that grows up on GPS (Global Position System) (GPS) basis, be a kind ofly can receive positioning satellite signal, calculate the accurate longitude in travelling carriage place and latitude and mobile station speed and direction through microprocessor, and be resolved in the generalized information system of the navigation terminal of placing or be installed in travelling carriage a kind of method and system that on the display of terminal, show then.

At first, this method and system cost is high always, and wherein critical piece microprocessor, memory and colorful display screen etc. almost all rely on external import, so fetch long price, and the user is difficult to accept.

Secondly, since these method and system must be in prescribed volume parts such as integrated microprocessor, gps receiver, memory, power subsystem, color/graphics, components and parts are various, circuit is numerous and jumbled, so the fault point is also more relatively, so this device useful life is short, failure rate is higher.With the liquid crystal display screen is example, and the failure rate of liquid crystal display screen is the highest always in all parts of mobile phone, and especially touch LCD shields, and repair rate can be in any more especially.Be applied in liquid crystal display screen on the guider and equally significantly improved the failure rate and the repair rate of product.

In addition,, upgrade or modification, need the user buy map datum again, and carry out burning again or upgrading is installed in case map datum has because the generalized information system in these method and system is preassembled.So just, produce the problem of two aspects: the first, the new edition map datum gives out information, and the user can't in time grasp.The second, in a single day need map or software upgrading, the user need buy copyright or licence, because the cost of map datum is very high, so user's purchasing price is also quite high, and the user is usually because the high reason of price is abandoned upgrading.Even three, user and user have obtained the new edition geodata, burning or fitting operation are also cumbersome, and it is inconvenient that the user usually feels.

At last, because these method and system are unit operations, the user can't recognize real-time position and cartographic information from this guider.When positional information and map datum generation real-time change, the user can't in time know.In practice, real-time position and cartographic information often are that most worthy, user need most, for example, and the idle parking space information in the congestion information of traffic, each parking lot, facility reconstruction information or the like.This device is being given the customer analysis compute best paths, and when drawing corresponding navigation mode and method, only the geometric space from fixing generalized information system of machinery obtains the result, add at most during some default, that infer, fixing constant parameter selectivity or the regular geometric space that is brought in the generalized information system calculate, therefore this result is difficult in the demand that in fact really satisfies the user, sometimes even situation opposite, that run counter to occurs.

(referring to " based on the GPS navigation location technology of electronic chart " Wu Ziyin

The blue Electronic Industry Press of " GPS principle and application " (U.S.) Kapp publishes)

This shows, present air navigation aid and system are the high integration that is made of a large amount of parts, high failure rate, expensive method and system that are applied to navigate based on the operation of unit generalized information system by terminal positioning technology such as GPS, AGPS, although it is of many uses, a lot of limitation are arranged still.

Second purpose of the present invention provides a kind of navigation system based on cordless communication network, utilize this system, can be easily, effectively, interactively carries out real-time navigation, significantly reduce simultaneously the cost of navigation system hardware and software, reduce the price that the user buys terminal installation, reduce user's map and software upgrading expense, allow location and navigation have real-time, interactivity, improve the reliability of navigation system simultaneously.The mode that allows location, navigation and use is flexible more, the scope of application is wider.This method comprises car-mounted device, boats and ships, aircraft, mobile phone and other people's application apparatus applicable to multiple travelling carriage, in case large tracts of land is used, can realize real full intelligent transportation rapidly, and have a tremendous social and economic benefits.This system can unite two into one navigation and monitoring, also can use its positioning function or monitoring function separately simultaneously.

The 3rd purpose of the present invention provides a kind of possibility and enforcement approach that " navigation " and " monitoring " two kinds of functions are combined, and based on another patent of invention " based on the interactive positioning and monitoring method and the system of cordless communication network " of same patent application people.

One, to achieve these goals, it is a kind of air navigation aid based on cordless communication network that the present invention solves the technical method that its technical problem adopts, and comprises following feature, step and submethod:

1.1 architectural feature

Air navigation aid provided by the invention is divided into three parts with the structure of whole navigation system: the network platform (side), navigation terminal (side), user's (side).

Network platform side is the hinge of whole navigation system, be carry out that based on network GIS processing, application and development, service provide, the significant element of information broadcast, information gathering and processing.The data computation of system and information handling task mainly concentrate on the platform side of network.

The navigation terminal side is the performance element of navigation.If system takes the terminal positioning mode, the navigation terminal side also is the unit that provides of positional information simultaneously.Navigation terminal normally with the same travelling carriage in mobile object holding position of needs navigation, promptly navigation terminal normally installs on mobile object (for example vehicle, boats and ships, aircraft etc.).End side offers user side as a reference with the result of network platform side by modes such as voice, images, or directly as the front end input of actuator application such as (for example unmanned) far-end controls.Navigation terminal should be simple as much as possible, only shares few data computation and information handling task, thereby reduce the fault point of navigation terminal and whole navigation system network, thereby improve the reliability and stability of terminal and system.The data computation of navigation terminal and information handling task depend on the bandwidth condition of cordless communication network: bandwidth is wide more, and the data computation of terminals share and information handling task are just few more, and promptly terminal can be done simply more, and cost is also low more; On the contrary, bandwidth is narrow more, and the data computation of terminals share and information handling task are just many more, and promptly the assembly of terminal is more, and structure is more complicated relatively, and cost is also high more.

User side is the initiator of navigation requests, and the user sends navigation requests to network platform side in several ways, can initiate by navigation terminal, also can not initiate by navigation terminal.If do not initiate by navigation terminal, think directly that promptly the mode that network platform side is initiated includes but not limited to: USSD (unstructured supplementary service data) mode, IVR (Interactive Voice Response) mode, WAP (Wireless Application Protocol) mode, SMS mode (Short Messaging Service) mode, and be provided with and request mode by visit Internet.

1.2 the location mode of map datum

In the present navigation system, map datum is curing or leaves in the terminal installation, general mode is: for fear of the inconvenience of installing and upgrading, map datum is installed in the guider by storage medium (comprising memory stick, SD card, flash memory etc.), reads when the CPU in the supplying apparatus moves then.Then be that map datum is left in the server of far-end in the method provided by the invention, the platform side of the network that promptly navigates.The terminal installation of navigation reads with the mode of Client/Server or the Brower/Server map datum to far-end by cordless communication network, even embedded specific software of terminal or program do not comprise map datum main, the basis yet.In this method, far-end be platform side map datum to all navigation terminal devices be real-time, share, synchronous, also be two-way, mutual simultaneously.

1.3 the feature of generalized information system

In traditional navigation system, generalized information system is intactly, moves independently, and is embedded in the navigation terminal apparatus system, belongs to the generalized information system of unit operation.And the generalized information system that designs in the method provided by the invention is based on the generalized information system of the network type of the network operation: this network GIS system can adopt the multiple network topological structure, for example ring-type or tree etc.; The spatial data that can concentrate or distribute calculates; Can between each node of network platform side, accomplish to load and dynamically share.

1.4 the function of system terminal

In traditional navigation system, after GPS module (gps antenna) in the navigation terminal device is got longitude and latitude, in embedded generalized information system, finish and resolve and computing, then the result is directly offered the user: show on the screen in the navigation terminal device, or, inform the user in the mode of voice by loud speaker or headset in the guider.

Method provided by the invention is except all functions that realize conventional navigation systems, outstanding functional characteristics is the navigation Service that can provide real-time, upgrade or upgrading as long as had in the generalized information system of network platform side, all terminaloriented side users' application and the service that provides will be upgraded or upgrading immediately thereupon.

1.5 mode and step that function realizes

At first, the user is by certain mode, for example: USSD (unstructured supplementary service data) mode, IVR (Interactive Voice Response) mode, WAP (Wireless Application Protocol) mode, SMS mode (Short Messaging Service) mode, perhaps by modes such as Internet access services websites, navigation requests is sent to the navigation platform side to be handled, navigation requests can comprise: starting point, the destination, Path selection requires to preset, and navigation results is represented information such as mode.

Through after the preliminary treatment, platform side is asked the positional information of the distolateral navigation terminal device of relevant final immediately.If system adopts network positions, platform side will obtain location information of terminals from the network positions platform, as LBS platform, AGPS platform etc.; If system adopts the terminal positioning mode, then the direct navigation terminal of platform side sends Location Request, and perhaps default navigation terminal is uploaded its positional information automatically under rated condition.

After obtaining the positional information of navigation terminal, navigation platform immediately within it in the generalized information system of portion to its data computation of being correlated with and information processing.This comprises the analysis selection of path analysis and calculating, air navigation aid and mode, the processing and the processing of other GIS project of navigation application.

Then, platform side is according to the bandwidth situation of getting in touch with end side, user's customization relation, hardware condition with terminal, the result that other assembly of generalized information system and platform side is drawn, send navigation terminal in the corresponding way to, navigation terminal is carried out navigation action thus, and can feed back to the user by corresponding mode.Particularly, after the navigation platform adnation becomes Path selection result in the navigation procedure, requirement according to 1.7 packets, be handed down to the guider of navigation terminal side with the packet of certain form, guider is by the TTS mode, the result that correct path is selected offers the user with the mode of voice, or the selection and the correct deformation trace in path is presented on the screen of end side, checks for the user.

1.6 satellite time verification and the correction of communications time delay

Because air navigation aid provided by the invention is networking, interactive, therefore separate about the GIS computing of real-time navigation and the expression or the execution of navigation results, will guarantee that the promptness of navigating and the key of validity are to make preliminary treatment to the delay problem in the communication transmission process, in the operational analysis process:

1.6.1 if locate mode is network positions (as modes such as CELL-ID, TDOA), navigation terminal need not receive satellite time usually, especially under the factor of considering the terminal cost, can't accomplish with the split-second precision of network platform side synchronous especially, then must provide accurate relatively time delay numerical value, be made as t1 by the network positions platform; Provide the descending time delay empirical value of platform side according to system running environment and network condition then, be made as t2 (comprising the GIS calculating process time) to end side.So total navigation system time delay T=t1+t2.The instantaneous velocity of the navigation terminal that directly obtains or obtained by the generalized information system analysis of platform side at the network positions platform is Vn, and n is the mutual number of times record of navigation.The n time navigation geographic distance correction amount S=Vn*T. that must do alternately then

1.6.2 if locate mode is terminal positioning (as modes such as GPS, GLONGSS, the Big Dipper, Galileo), utilize navigation terminal to receive satellite time, simultaneously also receive satellite time simultaneously, under the reception environment situation identical, can save atomic clock as time synchronized and benchmark checking procedure with condition at network side.

Obtain geographical location information (longitude and latitude) and record back for the n time at navigation terminal---the serial number that identifies this mutual number of times or communicate by letter with n with platform, to obtain positional information and satellite time (being made as Tu (n)) when preparing to upload, status command, positional information and other relevant interactive instruction are encapsulated in the packet with the form of agreement, send the platform side of navigation system then to through cordless communication network, platform side receives that the satellite time of this packet is Tr (n), after the process platform has carried out corresponding computing and processing, with the timing definition of passing to navigation terminal under the result is Td (n), navigation terminal is being received the result of navigation, and the time that begins to carry out navigation action is Tn (n).Therefore, the time delay Δ T (n) in once complete communication interaction process=Δ Tu (n)+Δ Td (n)+Δ Ts (n), Δ Tu (n) are the uplink time delay from the terminal to the platform side; Δ Td (n) is the downlink transfer time delay from the platform side to the terminal; Δ Ts (n) is the system handles time delay, because in the air navigation aid provided by the invention, most computing and Processing tasks are to have given platform side, what we were similar to thinks that this mainly is system's time delay of platform side, system's time delay of end side then counts Δ Tu (n) or Δ Td (n), and rule of thumb value and theoretical value are determined and revised.

Have last two to state as can be known, Δ Tu (n)=Tr (n)-Tu (n); Δ Td (n)=Tn (n)-Td (n); Δ Ts (n)=Td (n)-Tr (n)

For the time-delay that each data interaction produces, all write down and revise by the navigation platform side.Platform side and end side all be with the gps satellite time as lock in time, the uplink time delay Δ Tu (n) for the n secondary data in mutual just can obtain when platform side is received upstream data.When issuing data, platform also can obtain system handles time delay Δ Ts (n).

Therefore platform side can very accurate record and correction { Δ Tu (n)+Δ Ts (n) }.For the processing method of descending time delay, the present invention provides two kinds of methods:

First kind, experience value method.Platform side contrasts and chooses according to " experience control value table ", and " experience control value table " made by the factor of the descending time delay of influence, the influence degree weight of Delay Factor, the time delay empirical value that Delay Factor causes.

Second kind, adjacent time value method.The foundation of adjacent time value method is that adjacent twice mutual descending time delay is always very approximate, or even equate, because adjacent twice mutual physical environment, network condition, system mode and end side condition be recently like, so platform side is when revising this mutual descending time delay, the descending time delay that last time is mutual is as the foundation of this mutual descending time delay as the time delay correction.Promptly be: Δ Td (n)==Δ Td (n-1), each mutual Δ Td carries out record by end side, and with the n time mutual descending time delay Δ Td (n) record, storage, at the n+1 time alternately the time, the up platform side that sends to.

So the n time mutual total navigation system time delay Δ Tn=Δ Tu (n)+Δ Td (n)+Δ Ts (n).The instantaneous velocity of the navigation terminal that directly obtains or obtained by the generalized information system analysis of platform side at the network positions platform is Vn.Then the n time navigation geographical displacement correction amount Δ S=Vn*T. Δ S that must do alternately is the space displacement amount, and the simple two-dimensional linear relation must be carried out the correction based on the path by the GIS of navigation platform side absolutely not.

In addition, navigation terminal satellite receiver module self is optimized and verification in end side owing to receive the systemic time delay that processes such as star or analysis produce, and perhaps submits to platform side and focuses on.The realization difficulty of platform side and the actual bandwidth of cordless communication network are depended in the division of this task.

1.7 packet requirement

The present invention is the packet of certain format with the communication interaction data encapsulation between navigation system platform side and the end side, and is divided into packet header Message Header and inclusion Message Body.This packet can adopt multiple encapsulation format and decoding method, but following information must be contained in packet header: message total length, transmitting time record, message type code, serial number n, message protocol version, Termination ID number and reserved field; Inclusion then is the data content of each communication interaction, comprises longitude and latitude, status information of equipment etc.

1.8 communication means

The navigation system end side and the communication mode between the platform side that divide invention to relate to are divided into two kinds: a kind of is long connected mode, connection that can real-time online, and for example the GSM network GPRS connects, the data in the cdma network connect with voice such as IVR is connected etc.; A kind of is short connected mode, promptly be can not real-time online connection, for example connections such as SMS, USSD in the GSM network.

If system adopts long the connection, under the normal situation of bandwidth, as long as according to the method described above with the data packet form that requires, can realize real-time based on network navigation and commander.The present invention provides the short connection of a kind of utilization (USSD) to carry out the method for real-time navigation in this section

1.8.1 user's (user side) directly triggers (being fit to point-to-point monitoring)

1.8.1.1 the navigation terminal call of the direct navigation end side of user or send short messages makes the receiving circuit of navigation terminal begin ring, judges user's identity and authentication simultaneously according to calling number.

1.8.1.2 judge present connection status, and handle accordingly.If USSD is communicated with, but then phone or the present connection status of short message prompt user; Do not set up if USSD connects as yet, then hang up the incoming call ring immediately, navigation terminal is dialed the USSD Number for access simultaneously, establishes a communications link.

1.8.2 user's (user side) triggers (navigation command that is fit to point-to-multipoint) indirectly by the navigation platform side

1.8.2.1 the user after the authentication assigns navigation requests for the navigation platform side by the Internet (comprising wireless modes such as GPRS, WLAN), navigation server triggers navigation terminal by the call or the mode of sending short messages again and dials the USSD Number for access, initiates communicating to connect of navigation system.

1.8.2.2 the user makes a phone call or sends short messages to the navigation platform side, navigation platform is judged the identity and the authentication of user side according to calling number.By call platform (subscriber exchange) or SMS platform descending navigation terminal call or send short messages, dial the USSD Number for access then, initiate communicating to connect of navigation system to trigger navigation terminal.

1.8.2.3 the user dials the USSD Number for access, the navigation platform side is initiated navigation requests, navigation platform is judged the identity and the authentication of navigation side according to calling number, then by call platform (subscriber exchange) or SMS platform descending navigation terminal call or send short messages, dial the USSD Number for access to trigger navigation terminal, initiate communicating to connect of navigation system.If access-in resource is limited, the USSD Number for access that the user dials can consistent with the USSD Number for access that navigation terminal is dialed (for example shared * 109*2#).In this case, must distinguish corresponding user instruction and navigation instruction are set, and user's flow of navigation and navigation communication process, the navigation instruction that the user instruction of palpus assurance user input and the navigation terminal of navigation terminal side send can not be identical, also must differentiating and processing to its packet, in order to avoid produce conflict.

The communication connecting method 1.8.3 USSD navigates

In order to make good use of the USSD passage comprehensively, efficiently, use this method should understand the relevant parameter of USSD platform before to wireless carriers, comprise response time, time-out time, byte limit, information format.In this regular scope, use following method provided by the invention.

1.8.3.1 because USSD adopts is communication mode mutual, compartment, system must receive that message just can provide response, promptly USSD upstream data and downlink data be one to one, timesharing sends.The inventive method is divided into two time slots, i.e. ascending time slot and descending time slot with a mutual cycle.The USSD mode all has clear and definite requirement (normally 16 to 97 about byte) to the data volume of each communication, thus at each navigation terminal when platform sends information, navigation terminal must carry out flow control.

At first define Several Parameters: the maximum fault information Du (byte) of the each up transmission of USSD, the maximum fault information Dd (byte) of the each descending transmission of USSD, terminal is dialled the USSD Number for access and is provided the time T b (second) that responds between the foundation communication to system, terminal produces the numeric code rate Fu (byte per second) of upstream data, the time-out time To of USSD system, system produces the numeric code rate Fd (byte per second) of downlink data, the actual bandwidth Bu (byte per second) that USSD is up, the actual bandwidth Bd (byte per second) that USSD is descending.

In ascending time slot, the time T u (second) of up transmission Du receives that from terminal system message is to the time T t (second) of transmission information to system's (navigation platform side); In descending time slot, the time T d (second) of descending transmission Dd receives that from system's (navigation platform side) terminal message is to the time T s (second) of transmission information to terminal.USSD for singlehanded machine module connects: Bu=Du/ (Tu+Td); Bd=Dd/ (Tu+Td);

In the methods of the invention, for a mutual cycle, for making the load condition equilibrium of platform side and end side, according to the needs that network system is optimized, the system that is positioned at the upper edge sends stand-by period Ts and must set up corresponding relation with the terminal transmission stand-by period Tt that is positioned at the lower edge.An optimized proportion coefficients R is set, therefore is connected with following relation for a USSD:

R=Ts/Tt establishes the Tt=Δ, and the Ts=R Δ is promptly arranged.

USSD for singlehanded machine module connects, and guarantee that normal communication must meet the following conditions:

{(R+1)·Δ+Tu+Td}＜Min(Du/Fu，Dd/Fd)＜To

That is: Δ＜{ (Min (Du/Fu, Dd/Fd)-Tu-Td)/(R+1) }＜{ (To-Tu-Td)/(R+1) }

{ (To-Tu-Td)/(R+1) } is the normality item, { (Min (Du/Fu, Dd/Fd)-Tu-Td) Fu, Fd may be constants/(R+1) }, it also may be variable, in case { (Min (Du/Fu, Dd/Fd)-Tu-Td)/(R+1) } become to equaling 0, under the prerequisite that keeps communications status, Δ also must become to equaling 0.At this moment, system must trigger navigation terminal immediately and enable new mobile module, after triggering it simultaneously and dialing the time of TB at least of USSD Number for access at previous mobile module, dial the USSD Number for access and set up new USSD and communicate to connect, platform side must increase simultaneously provides one to insert thread and be this terminal use.

Connect for the USSD of two mobile modules after increasing is parallel simultaneously, the rule that proper communication must be satisfied is:

Δ＜{(Min(2Du/Fu，2Dd/Fd)-Tu-Td)/(R+1)}＜{(To-Tu-Td)/(R+1)}

·

·

·

N parallel simultaneously connection of USSD, rule is:

Δ＜{(Min(n·Du/Fu，n·Dd/Fd)-Tu-Td)/(R+1)}＜{(To-Tu-Td)/(R+1)}；

Bu＝n·Du/(Tu+Td)；Bd＝n·Dd/(Tu+Td)

After having set up new communicating to connect, the data that buffer storage produces may produce data and overflow and be made as DO.Connect by newly-established USSD, DO is passed down in the lump, and data merge when finishing in the opposite end.

Realize that above method must have synchronised clock accurately, insert specified byte in the downlink data of the inventive method system after the terminal phone module is dialed the USSD Number for access and be used for transmission, initialization system clock, the triggering signal that while makes zero as the terminal timer, insert the clock check sign indicating number then in the upstream data of navigation terminal in this reciprocal process, terminal clock and system clock are confirmed by check code all the time.

1.8.3.2 for the high navigation field of security requirement, must carry out scrambled to all navigation instructions, the coding mode selection difficulty cracks, takies simultaneously the few scrambled mode of byte number.

1.9 can expand to " monitoring " and " navigation " two-in-one approach

Another patent of invention " based on the interactive positioning and monitoring method and the system of cordless communication network " of same patent application people is combined with this method: the method for attachment that common user communication is mutual, and with the navigation server and the monitoring server parallel running of platform side, perhaps become one, distribute particular port to give being connected of navigation and monitoring simultaneously respectively, leave corresponding thread in the platform processes program and respectively processing is followed the tracks of in navigation and monitor task, and system resource is carried out the distribution of Redundancy Management by management platform, guarantee the system stability reliability service.So just " navigation " and " monitoring " function has been gathered together.

1.10 dynamically distribute navigation nodes load and work

The present invention will dynamically distribute navigation nodes load and work, to guarantee better navigation effect and quality according to cordless communication network states such as bandwidth conditions in numerous navigation nodes.When nothing communicates the bandwidth of network narrow the time, then bear more relatively computing and Processing tasks by the navigation terminal side, just map can be solidified or is stored in navigation terminal, only need include in the navigation platform downlink data inclusion longitude and latitude and the dependent instruction of prompting point, remaining is included in the computing of resolving described point on the map and generating the navigation hint result and operation and directly transfers to the navigation terminal side and finish and get final product; If in like manner the bandwidth of cordless communication network allows, then can save display screen and adopt real-time Voice Navigation, also can save embedded map datum or embedded generalized information system, the form that logical platform issues Navigation Picture or Streaming Media allows navigation terminal receive, and directly offers the user.

Two, in order to implement said method, solve technical problem and application problem that conventional navigation systems exists, it is a kind of navigation system based on cordless communication network that the present invention solves the technological means that its technical problem adopts, and comprises following technical measures:

System provided by the invention is the navigation system of implementing in full according to aforesaid inventive method, have functions such as location, navigation and dispatch control, also can be separately as " based on the navigation system of cordless communication network ", " based on the navigation system of cordless communication network " and " based on the dispatching and command system of cordless communication network ", perhaps the selection of above-mentioned some function is used.Native system has adopted the multiple communication connecting method that relates in the foregoing invention method simultaneously, can satisfy the requirement of multiple communication condition in actual applications, and can require to select flexibly according to user's request and post and telecommunication tariff.

2.1 the data communication of carrying out between the network of relation unit in the navigation platform side connects, and comprises the connection of application layer.

2.1.1 directly and LBS (the location-based service of Location Based Services) platform, communicate to connect platform, signaling triggering platform, GIS server, WEB server, database server, application server and be connected (preferably using optical cable) with navigation server.If system loading allows, GIS (Geographic Information System) server, application server, WEB server, database server can partly or entirely be integrated in the navigation server.Communicating to connect platform is the various general names that communicate to connect mode and interface, comprises long and short communicating to connect such as SMS messaging platform, USSD (service of unstructuredsupplementary service data non-structural supplementary data) platform, GPRS platform and voice platform.

2.1.2 triggering platform, signaling constitutes by subscriber exchange, SMS platform interface, GPRS transport module, CDMA transport module, standard communication interface circuit.The effect that signaling triggers platform is that the mode by phone ringing, downlink short message or descending online transmission packet triggers and sets up navigation channels, can adopt the mode of phone ringing, downlink short message mode or descending online transmission packet simultaneously, carry out one main one Hot Spare that is equipped with and connect; Also can use a kind of mode wherein separately, trigger in the platform in signaling like this and can save subscriber exchange or SMS platform interface.Subscriber exchange drawn game end switch connects with trunk line, and subscriber exchange links to each other through the communication interface circuit conversion by subscribers feeder with navigation server; SMS platform interface one end is connected with Short Message Service Gateway by the API agreement, and the other end is connected with navigation server by standard communication interface.Need not increase, change signaling protocol newly, all adopt the current signaling system of Virtual network operator (for example signalling system No.7).If terminal quantity is few, simultaneously in order to save the initial stage construction cost, signaling triggers platform and can use phone dialer, SMS transmission module, standard communication interface circuit and queuing buffer circuit to replace constituting, and phone dialer, SMS transmission module directly are connected with navigation server by the standard communication interface circuit.If signaling triggers platform and only uses the downlink short message mode, then this platform can save, and navigation server directly need only be linked to each other with Short Message Service Gateway by corresponding API agreement to get final product.But consider: the needs of the communications cost of navigation channels are set up in the issuable delay of note, non-connection-oriented characteristic and reduction, and the present invention advises separately or cooperate adopting the phone ringing triggering mode.

If system selects the user to trigger by navigation terminal and sets up the navigation data channel, especially system adopts under the situation of long connection communication mode, and above-mentioned signaling triggers platform and can simplify even omit.For example the user is by communicating to connect by button initiation that is provided with on the terminal and navigation platform side.In addition, can set certain trigger condition by the various transducers and the peripheral circuit of navigation terminal side, satisfy in end side under the situation of this trigger condition, initiate to set up communicating to connect between navigation terminal side and the navigation platform side by end side, for example be used for vehicle-mounted navigation terminal device, can external door limit circuits for triggering, in case the user opens car door, then be initiated to communicating to connect of navigation platform side immediately, start effective data interaction, and begin navigation.This just allows the user can use this system more easily, has saved data transfer throughput simultaneously and when beginning to navigate, the GPS module is searched the time of star and cold start-up at every turn.

2.1.3 by corresponding API agreement and data-interface, navigation server respectively with LBS (the location-based service of Location Based Services) platform, communicate to connect platform, signaling and trigger platform, GIS server, WEB server, database server and directly be connected, can take the direct-connected mode of IP with LBS.If the present invention need be carried other value-added functionality business, then must on (location navigation) navigation server, insert required application server by corresponding API agreement, provide interactively valued added applications service by demand to the user; Also can be on navigation server the content of manual entry valued added applications service, carry out interactively issue by demand to the user then.

2.2 the data communication of carrying out between the associated component in the navigation terminal side connects.

2.2.1 basic part comprises: CPU processor, satellite receiver module (comprising GPS, the Big Dipper or Galileo system), mobile module (must support data communication functions such as USSD, GPRS, SMS), channel trigger, various types of memory, Various types of data input/output port, transmitting-receiving control port, synchronised clock, timer, power circuit, standard traffic port constitute, and can connect by computer data bus between each circuit devcie.
