Embodiment
Fig. 1 shows the block diagram of communicator, and said communicator comprises: first member 101 that can be provided with through programming; Be connected to second member 103 that can be provided with of first member 101 that can be provided with through programming through programming; And the 3rd member 105 that can be provided with that is connected to first member 105 that can be provided with through programming through programming.
Second member that first member, 101 requests that can be provided with through programming can be provided with through programming is to the non-existent network address (that is, to non-existent http address) transmission particular command.In response to this, the 3rd member 105 that second member, 103 notices that can be provided with through programming can be provided with through programming is about the request of transmission particular command.In response to the information of indication described request, the 3rd member 105 that can be provided with through programming is carried out particular command in response to the information of indication described request.
The 3rd member 103 that can be provided with through programming is preferably carried out the 3rd computer program; User application (local application) for example; Said the 3rd computer program receives order; Because the environment of its operation of first computer program inquiry (web browser, and and then be user application) order sent to represent himself.Web browser (second computer program) is provided, because there is java script on the webpage, and java script can't be directly and the 3rd computing machine interprogram communication.
For instance, can adopt above notion management navigation content (such as, for example route arrangement information or route are arranged map).For instance, first computer program can initial for example remote server (comprising for example active page) with the 3rd computer program (the local client application program is provided) between communicate by letter.For instance, local application (or remote server) contains online (network) shop of selling voice, map etc.This online store preferably uses integrated web browser to implement.Local application instruction built-in browser is downloaded the webpage in the said shop of expression.In addition, the online store page possibly contain java script, and therefore, the page of download can use for example so-called AJAX technology to communicate by letter with remote server.Yet at specified point, the java script on the page must provide particular command to the local application client.One instance command is after the user has bought the voice in the online store, " to download this voice ".Though java script can be implemented credit card and handle, its can't actual download be installed to for example guider, so it sends order or order is sent in request.
Send order to the local application client in the following manner: at first (for example in the java script on the webpage in the shop) made particular request, and then sends request to non-existent address (for example http://ttds).(for example, embedded) web browser notify its main frame---local client application program---about described request.Local client is known the address that does not exist http://tt.ds such, so local client (for example) extracts order [s] and carries out said order.In order to quicken further processing, then can cancel illusory request to http://tt.ds.
Except for example downloading the navigation content as map and voice; Also can for example indicate local client (providing) (for example to open more multiple web pages by the 3rd computer program; The second shop page) or close said webpage, show Pop-up message, switch in the local application certain window (for example; Useful " being installed to device " panel after downloading voice), user certificate is perhaps inquired and sent to the new local application version of inspection, inspection to the renewal of navigation content, the inspection renewal to the simulator of analogue navigation device, to the renewal of device firmware, inspection.
Fig. 2 is illustrated in the block diagram that detects the treating apparatus of certain computer command in the character string of representing uniform resource identifier (URI).Particular command can comprise predefined order header, and it is the command name from a plurality of predefined command names at the back, and its back has one or more order independents variable according to circumstances.Treating apparatus comprises: determiner 201; It is used for confirming whether character string comprises predefined order header, and said determiner is further through being configured under character string comprises the situation of predefined order header, to confirm whether the substring after the order header comprises command name; And device 203 is provided, it is connected to determiner 201, provides predefined order header and command name as certain computer command under the said situation that provides device 203 to comprise command name at the order header.
The notion of describing among Fig. 2 also can for example use (executable) computer program to implement.In addition, relevant with URI description also is applicable to URL (uniform resource identifier).
As for URI, same URI also can be used as on the webpage or Email in " target " of hyperlink.Under said situation, can activate URI through for example on this hyperlink, clicking.Further possibly use from the URI that is embedded in the java script program on the webpage.Yet the program that other this locality is installed on the computing machine for example also can be used this URI.For example, e-mail address book plug-in unit can use this URI to send to from the address of e-mail program to be installed in the local application on the PC for example.
For instance, local application (for example, management navigation content) provides the UI of himself.Yet further content can be used for being stored in the outside navigation purposes of local application.For example, e-mail program contains address book, and said address book comprises a plurality of addresses as the WWW.Under the situation of local client said address capable of using, address book will be useful.Other can (for example) provide navigation content interested to the form of on the WWW, installing through local application with permission, and local application can implement to allow the customization < header>of this access: ///the URI scheme.
URI scheme through RFC 3986 definition defines a framework, in said framework, can implement a plurality of agreements.Modern operating system allows application program with the appointment handle of himself registering the URI that is used to have given agreement as.The local application (local client) that is for example provided by the 3rd computer program mentioned above is used for < header>himself registering as: ///handle of URI of beginning.
The remainder of URI is as the command list (CLIST) in the local client.Use the method, can for example be encoded to < header>as the address of " Amsterdam, Rembrandtplein 35 " and so on: ///Address? Amsterdam&Rembrandtplein&35.
In this regard, "? " " & " character is optional, and can be by other predefined character or character string replacement.
Any Application except the local client of supporting URI all can require operating system (OS) to resolve URI when running into this URI.OS will notify again the local client user view use " Address? Amsterdam&Rembrandtplein&35 ".Local client then provides the tabulation of the selection where said address work is managed to the user.Yet, have a plurality of navigation task of using the address.
Use Same Way, and hypothesis " http://shop. < web address >/voices/dutch/bram.toc " be Dutch voice, then possibly create following URI:
<header>:///Install?http％3a％2f％2fshop.<web
address>％2fvoices％2fdutch％2fbram.toc
If this URI will appear on the webpage, and the user clicks said URI, and web browser can require OS to transmit this URI so.Will OS require local client to take Install? Http%3a%2f%2fshop. < webaddress>action that %2fvoices%2fdutch%2fbram.toc hinted, in the case, it is to download bram.toc (contents table) from given address.
The format specification of order hereinafter will be described.
With reference to general URL form (it possibly comply with RFC 3986), order can have following structure:
<header>:///command-list
Wherein:
command-list ＝command[′#′command]+
command?＝command-name′?′argument-list
Command-name=(title of the order of being supported sees below)
argument-list ＝UrlEncode(argument)[′&′argument-list]+
argument ＝UTF8-string
With reference to the traditional URL form, order can have following structure:
<header>://legacy-command-list
Wherein:
legacy-command-list ＝legacy-command[′&′legacy-command]+
legacy-command ＝command-name′(′legacy-argument-list′)′
legacy-argument-list ＝UrlEncode(argument)[′，′legacy-argument-list]+
Traditional URL can't contain character "? ", and suitably URL always contains said character.This makes possibly distinguish traditional URL and suitable URL.It should be noted that these URL do not comply with RFC.Many URL processing entities will change said URL during handling.Exactly, many window networking browsers will add extra "/", so that URL is met.Some web browser is not supported said URL.Local application is attempted the URL of the improper formation of intercepting, so that handle the application program of various support URL, but uses the traditional URL form can make said method complicated more.
Order can have following structure and independent variable:
Structure: EMailContact? Folder-ID&entry-ID
Independent variable: e-mail contacts ID.
Local application will be from e-mail program the searching linkman data, and where the inquiry user manages (demonstration on map, navigate to said data, be added to preference etc.) to it.

TOC (contents table) form can be specified by the XML outline (schema) in the for example file " TOC format.xsd ".
The project of following type can be installed by user (for example third party): POI (interested point), data set, voice, color scheme.
Structure: Execute? URL
Independent variable: the HTTP URL that contains the text of actual command tabulation.
Resource by the URL indication has mime type " text/plain ".
For example, if will order part transmission will produce long URL, can use this order so as URL.
When in the tradition order, using Execute () command name, URL can provide traditional command list (CLIST) in response to this.
Structure: SwitchTab? Tabname
Independent variable: the title of the label (tab) that server is created.
If label exists, local application will switch to this label.If label does not exist, local application will be remembered title so, in case and server created label really, just switch to said label.Local application will only be remembered a title; The 2nd SwitchTab order will replace first.
Structure: <user or host name>Page? Tabname&hostname&URL-path&anchor
Independent variable: bookmark name, Hostname, path (with respect to Hostname) and the URL anchor (anchor) of the new label of creating.
Local application at first checks whether there is the label with given bookmark name, otherwise it creates a label.This label then is arranged to http://hostname. < web address >/URL-path#anchor with its URL
Local application can refuse to have the Hostname of non-alphanumeric characters, and this can stop title to be injected.For example, Hostname " badguys.com/ignore " may be rejected, because ". " and "/" is invalid.
To mention that like hereinafter order can possess cryptographic signatures, thereby allow verification command.For instance, can use following imperative structures:
Structure: < PublicKeyldentifier >? Command-list&signature
Independent variable: command list (CLIST) and signature.
This order is used to carry out only the tabulation of the order of being carried out by the user.Signature confirms the authenticity of command list (CLIST).
signature＝Sign<PrivateKey>(command-list)
But it should be noted that any certifying signature per capita (use public keys).
Sign < PrivateKey>(command-list) can implement as follows:
Command list (CLIST) is the UFT-8 string, and therefore can be expressed as byte sequence.
Command list (CLIST) should not encoded with URL when being used as the input of Sign < PrivateKey >.
With reference to encoding scheme, calculate the SHA-256 hash H (256 positions) of this byte sequence.In addition, and the use private key (Q, M), compute signature value (Q
HModulus M).Signature is stored as microcephaly (little-endian) byte sequence (both not required also not add and filled up that purpose was to make URL keep shorter) of Base-64 coding.The same with all independents variable, command list (CLIST) will be the URL coding with the signature independent variable.When in the tradition order, using < PublicKeyldentifier>() command name, first independent variable should preferably traditional command list (CLIST).
Deciphering is opposite process: local application hold public keys (P, M).The SHA-256 hash H of calculation command tabulation (after the URL decoding) (256 positions).(P M), calculates and countersigns (P to use public keys
HModulus M).Signature is carried out the Base-64 decoding to obtain (Q
HModulus M), wherein calculate product (P
HQ
H) modulus M.If signature with countersign coupling then accept signature, this means (P
HQ
H) modulus M equals 1.
If there is not the order independent variable, then also can use above notion.In addition, command name can comprise some parameters of assigning semanteme to independent variable.For instance, each independent variable can be used two kinds of possible modes and parameter matching, and said dual mode is called localization method and nomenclature hereinafter, and this is similar to the function call syntax in the programming language.
With reference to the location grammer, if command name has for example three parameters, and three independents variable are provided, so first parameter and the first independent variable coupling etc.For instance, address command has three parameters: city, street and number.So actual URI will contain three independents variable, wherein first independent variable will be interpreted as city title etc.
Perhaps, can support following grammer:
Address?Street＝RembrandtPlein&City＝Amsterdam。
In the case, each independent variable comprises the parameter title.Therefore, these are called " name " independent variable.
In addition, the parameter of mentioning more than can stipulating is mandatory parameter.This means the independent variable that must have coupling.Replace in for example use "? ", can use other parameter to come the separation between directive command title and the order independent variable.In addition, also can adopt other mechanism, for example force the command name (this hints the first letter beginning, the first order independent variable after the said position) of regular length.
< header >: ///in general URI can contain one or more orders.Therefore, can use character " # " (or any other character, for example " and ") order of contacting.
Fig. 3 shows the block diagram of communicator be used for being installed in response to execution the behavior of device firmware program and analogue navigation device on the guider.Said communicator comprises: device 301 is provided, and it is used to the information that provides relevant with the device firmware program; Determiner 303, it is connected to provides device 301, whether is used to confirm to be installed in current firmware program on the communicator corresponding to the device firmware program that is installed on the guider; And processor 305, it is connected to determiner 303, is used for the current firmware program on the executive communication device, so as current firmware program corresponding to the situation of device firmware under the behavior of analogue navigation device.
Communicator can be provided with and dispose through programming, so as to carry out the may command simulation process more than the local application mentioned.
The simulation notion is further supported the portability and the availability of guider.Usually, (portable) guider has for example small screen, and said small screen also serves as its input.On the contrary, for example (desk-top) computing machine (for example, PC) has much bigger screen and a more senior input method.Therefore, if guider by the computer control that can for example be connected to guider, the many tasks that can on guider, carry out are so carried out more easily.In addition, the processor of computing machine (for example CPU) is faster.
In addition, the simulation notion can be implemented through programming, and for example is embedded in the local application, so that make that effectively for example computing machine (representing the embodiment of communicator) can use more competent computer resource to control guider.
When guider being connected to local client (or being connected to communicator), confirm to be installed in the firmware version on the guider.If local client has the computing machine equivalent versions of firmware, begin said firmware so.If have no the version of equivalence to use, but there have network to connect (for example, the Internet connects) to be available, and local client can inquire which the home server equivalent versions is so, and can be from where downloading said version.
Fig. 4 illustration provides the method for customizing messages to network entity from further network entity.Said method comprises via communication network from the request of network entity to 401 pairs of customizing messages of further network entity transmission; And transmit 403 temporal informations from further network entity to network entity via communication network, said temporal information indication is connected to further network entity to be used to obtain the special time moment of customizing messages.Said method can for example be implemented (for example, as local application) in software, said software is carried out said method step when being performed.
For instance, the user can require traffic returns every day (specific and user's information specific) about specified link to local application.Local application will be followed every day for example in the report about traffic jam on the road of being asked and traffic hazard of the time showing of request.When in local client, carrying out the traffic returns request, client for example is forwarded to server with request at once.To given user request msg is stored on the server.In response to described request, server is beamed back the time that local client is answered the poll home server.In addition, when same user logins once more, home server all will be told the time of local client poll services device.Server is reacted to poll report and is sent the actual traffic report.Local application for example formats traffic returns to be used to show purposes.The result is at server side, but still by the initial connection of client with all data storage.This allows local client being used as software program when carrying out on computers, breaks through fire wall or ejects blocker and show the traffic warning.
In order to confirm user profile so that obtain for example user's information specific, user capable of using is the login certificate of input manually.Perhaps, local client can have been stored login certificate in early days.No matter be which kind of mode, if local client has login certificate, when local client that software program for execution provides, local client all can send login certificate automatically so.If local client does not have certificate as yet, the user can manual initial login so.Under said situation, local client will be pointed out the input certificate, at once certificate sent to remote server, and go back Store Credentials for using in the future.
The method of the order that Fig. 5 illustration is used to provide cryptographically signed, said order comprise command name and at least one order independent variable.Said method comprises the cryptographic signatures that produces 501 command names, and utility command title, signature and said at least one order independent variable constitute the cryptographically signed order of 503 (for example, series connection).
For instance, can adopt the encryption and decryption scheme of the embodiment description that combines Fig. 2 to provide and certifying digital signature.
For instance, can comprise order through the URI that identifies with two independents variable; First independent variable is the character string as order.Second independent variable is first independent variable " digital signature ".Preferably, adopt the standard public key cryptography to use private key to sign first independent variable, said private key provides digital signature.For instance, the local client that has the public keys of coupling can be countersigned first independent variable.And only under the situation that key equates, sign and countersign be only complementary.If this situation, local client is trusted first order so, even and the order in first independent variable will be considered to dangerous, will carry out first order.
Also can use the URI mechanism of above evaluation to upgrade the firmware on the guider.Preferably, can allow to duplicate or update command, yet can not change order.Therefore, for example may cause the infringement that to repair to guider with wrong firmware update guider.
According to an embodiment, then as first independent variable in another order (cryptographically signed order), wherein said signature is as for example second independent variable in the order of signature.The structure of cryptographically signed order can be following:
verify_command(commandname1(argument1，argument2，argument3)，signature)
Can through to should certified order application examples such as private (secret) key produce signature (being directed against second independent variable of external command), that is:
Commandname1(argument1，argument2，argument3)+private_key＝signature
To countersign in order producing, can to use similar algorithm:
commandname1(argument1，argument2，argument3)+public_key＝countersignature。
If sign and countersign and correspond to each other verification command so.Preferably, can adopt the for example standard public key cryptography method of RSA or DSA algorithm and so on of picture in order to sign purposes.
For instance; Consider order < header >: ///< PublicKeyIdentifier >? Install%3fhttp%3a%2f%2fintranet%2fplus%2fdocuments%2ftem p%2fnavcore_6.522.7709.go510-go710.toc&JYrSIQ
Wherein < PublicKeyIdentifier>is the actual command title that is used for by the order of user's evaluation.First independent variable is Install%3fhttp%3a%2f%2fintranet%2fplus%2fdocuments%2ftem p%2fnavcore_6.522.7709.go510-go710.toc
This is an embedded command.The actual command title is to install, with "? " Be encoded into %3f, and remainder is the independent variable of installation order.The user is with its private key signature installation order, and the signature that occurs is JYrSIQ.For verification command, can produce and countersign.If signature order is correctly countersigned coupling so.
If another user attempts edit commands; For example < header >: ///< PublicKeyIdentifier >? Install%3fhttp%3a%2f%evil.com%2fnavcore_6.522.7709.go510-go710.toc&JYrSIQ will not calculate so and countersign with the different of signatures match.Therefore, refusal is installed the content from evil.com.
Fig. 6 shows the communicator of the current navigation content be used for updating stored in guider.Said communicator comprises: retrieve element 601, and it is used for from the information of the current navigation content of guider retrieval indication; Transmitter 603, it is connected to retrieve element, is used for via the information of communication network to the current navigation content of remote network device transmission indication; Receiver 605, it is used for receiving the navigation content of upgrading from remote communication devices; And processor 607, it is used to show and the relevant information of upgrading of navigation content, perhaps is used on guider, installing the navigation content of upgrading.
Can the information of the navigation content of indicating current or renewal be transmitted as the content file table, said content file table is indicated for example content type, content name, content size or contents version.In addition, can the transmission information relevant with device identification or ID.
Remote communication devices (for example, server) can comprise the database of the tabulation of the for example available navigating items of storage (for example, map, route arrangement information, GPS location etc.).In addition, remote server can be before the content that transmission is upgraded the user's that authorizes because of for example reservation state of inspection right or the right of the guider authorized because of for example device identification.
