Abstract
A method and computing system for refreshing, from a server, objects stored locally in a client device remotely connected to the server through a communication device. The client device sends a refresh request message along with its list of object identifiers and the digest of the object itself, which are stored in its local memory. The server, after checking the transactions subscribed by the client device, sends back a refresh reply message with the objects stored locally in the client device and needing to be refreshed. The server will also send new objects to the client device according to the transaction it subscribes to, and send specific codes to specify to the client device that objects that are no longer part of the transaction are to be deleted.

Fig. 1 is the description to environment of the present invention.The webserver (100) provides service by network (130) to client terminal device (110,120), and network (130) can be the internet, and can comprise mobile communication.The transmission request that the Internet client terminal device uses web browser server to be sent visit information, described information can be the object of any kind, as html page or image file (JPG, GIF etc.) or audio file (WAV, MP3 etc.), and form alleged network documentation (150) usually.Server record client terminal device label (identity) for example for mobile phone, utilizes its IMEI (international mobile device label).What the screen phone client terminal device can send its internet apparatus (appliance) presses the standardized identification code of ISRF.More generally, all client terminal devices send the identification code that is similar to as the sequence number of unique identifier.
Server also writes down by client terminal device predetermined service and more others, client terminal device may to this service provide and the customizing messages in its profile, described interested.In description of preferred embodiments, be scheduled to a simple example of service, and do not had profile, but those skilled in the art can easily utilize the client profile to rewrite the preferred embodiment.Described information can be static, for example is used for the menu of cooking information service; Perhaps can refresh every day, for example newspaper; Perhaps refresh every day several times, for example refresh with meteorological position (weather site).According to preferred embodiment, server will only send and the upper level of the previous transmission new information of not comparing.In Fig. 1, client terminal device is off-line, and need be refreshed by the webserver.Client terminal device sends the clear and definite refresh requests that has again synchronizing information, and it is local that described synchronizing information again is stored in this device, and with the helping service device with needed correct grade of other information sync client end device again.Network documentation (150) is at first by " coming source server " (140) storages, describedly comes the source server response request described network documentation to be sent to the remote web server (100) that subscription client device (110,120) is provided service.Remote web server only refreshes client terminal device with the network documentation object that has upgraded.In a single day client terminal device is refreshed, and according to this preferred embodiment, can utilize the object that has refreshed to rebuild network documentation (150) in this locality.
According to present embodiment, have as the user client device of webserver information service: the local storage unit of communication facilities, set up the object of network documentation with storage; And at least one processor, to rebuild network documentation, show these documents and send refresh requests.Server is by the download message resynchronization and refresh described device.Described device can receive described information, revises the synchronizing information again of local objects stored and local storage.Described refreshing can be used as the program of moving in the computational resource in server and client side's device with method for synchronous and realizes.
Fig. 2 shows three tables that are stored in server end.Client terminal device is just being browsed " local page " that is made of object.To liking the data block of handling as single entity.For the purpose of this preferred embodiment, to as if refresh unit (unit).
Server table has reservation table (200), trading object table (210) and Object table (220).Reservation table be used to store by the transaction id unique identification and with " transaction " that be associated by the given client terminal device of device ID uniquely identified.Each transaction is predetermined corresponding to the service that server is provided.Utilize this table, server can be found out all transaction relevant with given client terminal device.The trading object table is that each the transaction storage by transaction id sign is relevant with this transaction and by the tabulation of the object ID uniquely identified object of server-assignment.Server uses this table to find out the object ID that all belong to the transaction relevant with given client terminal device.Object table is kept by server, make each object ID and object signature promptly " summary " be associated, be used to be designated security and the content of the text that uses.MD5 is the unidirectional shuffling information (one-way hash) that provides the reduced representation of object.The MD5 signature makes it possible to sign and has other big text of higher security level.Can use any other " summary " in a preferred embodiment.Server serves as " agency " function, " comes source server " from Local or Remote and obtains object.At each server when always source server receives new object, compute signature.Object table comprises the signature that the up-to-date object value that receives and corresponding calculated go out.Signature, object length and the sign that server goes out for each object ID storage computation provides the local URI (unified resource identifier) or the long-range URL (URL(uniform resource locator) address) of the internet of the network documentation that comprises described object or the network address that in-house network comes source server.Described address is not used in to be refreshed and resynchronization client terminal device, and is used for periodically the up-to-date object rank of always source server requirement by server.
Fig. 3 shows an example of group of objects, and how server is selected to refresh client terminal device in all these objects.Determine to belong to the group of objects of the transaction of given client terminal device by reading reservation table (200) and process object table (210).As example,, comprise Obj2, Obj1, Obj3 and Obj4 to device T01.Server is informed in answers the request that client terminal device sends and resident which object in the client terminal device before refreshing, and this will describe in detail with reference to figure 6 hereinafter.These objects form second group to Fig. 3, comprising: Obj5, Obj1, Obj3 and Obj4.Common factor between two groups of whois lookups is to determine need to be the object that client terminal device upgrades: Obj1, Obj3 and Obj4.Object Obj5 no longer is the part of the predetermined transaction of client terminal device, and server is with any information about this object of storing in requesting client device deletion Obj5 and the described device.Object Obj2 is not a resident object in client terminal device: server must refresh client terminal device with this new object.For resident object in client terminal device, Obj1, Obj3 and Obj4, if resident version does not have the signature identical with its latest edition in the client, server must refresh client terminal device with the latest edition of this object.Because will comprise the signature of object in the request that is sent by client terminal device, so server will be known the signature of object resident in the client terminal device, this will describe in detail with reference to figure 6 hereinafter.
Fig. 4 shows server will download to the form of client terminal device with list object that it is refreshed.The example of Fig. 4 shows and be total to n object from Obj1 to Objn.In the list object each " object " comprise object ID, as from the object signature of the last level of Object table signature, from the object length of Object table and the object itself that reads of source server always.
Fig. 5 shows the renewal to active user's object set table of keeping in the client terminal device.This table comprises the signature of object ID and object.By the server-assignment object ID,, and download said two devices in the refresh operation in front by the server compute signature.Active user's object set table comprises the last level that receives from server.In case receive the refresh requests that is sent by client terminal device, server will be as shown in Figure 3, selection will download to the object of client terminal device.When client terminal device receives the list object of server transmission, upgrade local object versions, client terminal device also correspondingly upgrades described table (described object ID and signature).In Fig. 5, first table is the previous rank (500) before refreshing, and second table is the last level (510) after refreshing.Show with Fig. 3 in identical example, new rank (510) no longer comprises quote (reference) to Obj5, and introduces newly the quoting of new object Obj2, and only upgrades the signature of the object Obj3 that must change, because its signature changes.
Fig. 6 shows the message that exchanges between client terminal device and server.Used agreement is HTTP in the example, wherein utilizes " POST (issue) " order to send request (600).The message of issue is followed the refresh requests grammer of this preferred embodiment.This order is " Refresh (refreshing) ", and Termination ID is T01 in this example, and the object ID tabulation is the content in local active user's object set table of storing in the client terminal device with related signature.The request that the client terminal device issue refreshes local objects stored.The client terminal device of working during for this off-line can send once this request every day.Server is answered this request by the identifier that reads client terminal device, and to utilize two tables be reservation table (200) identifies all corresponding to the transaction of this client terminal device object relevant with these transaction with all with trading object table (210).According to shown in Figure 3, server will determine which is to be the candidate target of this client terminal device (320) renewal.Then, by the reading object table, server reads signature to the candidate target that each will refresh.The signature of storing in the Object table is the signature that calculates when the object of server source server reception always and storage last level.If the signature that comprises in the signature of Object table and the request from client terminal device is identical, server will not send this object in it is answered so.In this example, Obj1 has different signature (being respectively S12 and S41) with Obj4, so server will not send them.By the Obj3 of the local storage of client terminal device corresponding to rank by signature S32 sign.In server, the rank of being stored has different signature S31.Must send current other Obj3 of level to refresh client terminal device.Also must send new Obj2, and server is because Obj5 no longer belongs to the predetermined transaction of client terminal device, so must advise deleting Obj5 from the storer of client terminal device.
Also show answer (610) among Fig. 6 from server.Utilize http protocol, server sends answers the simple message that gives out information.This order is " Refresh_response (refresh response) ", is " Object_list (list object) " according to the form of describing with reference to figure 4 subsequently.Obj3 is sent with the signature S32 of renewal, new object length and contents of object itself.Obj2 itself is sent with the signature S21, object length and the contents of object that calculated in the past.As mentioned above, Obj5 no longer is the part of the transaction of client terminal device, it is not refreshed, and signature identifier 0 in the refresh response and object length identifier 0 mean must cancel this object from the local storage of client terminal device, and must delete described record from active user's object set table.
If under the situation of fatal collapse, reinitialize client terminal device in maintenance or after by the new equipment replacement, then active user's object set table is empty, and described request is used to send all objects of the transaction of being scheduled to corresponding to client terminal device.Refresh command by the client terminal device issue will not comprise object.This be in a preferred embodiment announcement server its need receive mode corresponding to the object of all last level of its predetermined All Activity.
Fig. 7 is according to this preferred embodiment, utilizes the process flow diagram of the method for the client terminal device that a group objects resynchronization will refresh.
Server is at first set up list object (760) with the object that will upgrade.As described in reference to figure 4, list object comprises institute's objects stored content self in object ID, the object signature of each object, the object length that reads and the server from Object table.In list object, server adds the object ID of the new object that adds with the change in the change of transaction or the transaction, object length and the contents of object (770) that object is signed, read from Object table.The back that comprises the tlv triple (triplet) of object ID is the particular code of indicating the object that will delete owing to the change in change of concluding the business or the transaction.It is a kind of that appointment will be deleted an object may be to put into object ID and corresponding to the null value of signature and object length in list object.Can use other any sign in conjunction with object ID, notify client terminal device will delete this object (770).Server by utilizing client-server http protocol sends the response (780) to refresh requests.Client terminal device receives list object, and can read object ID, object signature, the object length of each object, and utilizes object length reading object content, with the end of identifying object.The information that utilization receives, client terminal device upgrades active user's object set table with object ID and corresponding signature.The object entry that its deletion will be deleted, and add new object entry.Then, use the last level that is sent in its local storage, to replace contents of object itself.Server has refreshed with its needed object and is synchronous again.
