Description

A kind of storage of browsers local page and update method
Technical field
The present invention relates to the storage and the update method of browsers local page.
Background technology
At the transfer resource of communication network in the relatively limited and environment that need pay to the use of transfer resource, for example, in with the cordless communication network of note as bearer path, the menu interface system of the interactive application of terminal tends to use local page (Resident Page) mechanism, handle those relatively stable, as seldom to change content of pages, effect is to avoid allowing these contents of user's repeated downloads, thereby saves air resource and customer charge.
Go up the microbrowser that uses with SIM (subscriber identification module) and be example, local page resides among the SIM for a long time, and when the user needed them, browser needn't send upstream request, but directly read these pages from this locality.The storage of what menu and some teachings information before local page is particularly suitable for.When content changed, server can upgrade local page.
In the menu technique of in the past SIM interactive application, the renewal of local page (comprise increase, deletion and revise the page) has following several mode:
First kind: be responsible for maintenance by user oneself, when finding the project that needs renewal is arranged, download again.STK (SIM kit) card+OTA air download technology for example realizes the updating menu of local page exactly by this mode.This mode needs the user constantly to go renewal of the page situation on the awareness network server initiatively, and the page that needs the are upgraded this locality of downloading has increased user's operation burden and inconvenience so then.
Second kind: in case local page content needs to upgrade, the webserver is revised each user's local information by extensive PUSH (propelling movement) information.For example, the microbrowser WIB of SmartTrust company adopts this mode to upgrade local page.But this mode can run into many PUSH information and can not arrive and cause revising invalid situation, and worse, for certain user, server can't judge whether its specific webpage is successfully revised.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of storage and update method of browsers local page is provided, and can finish the renewal of local page automatically, reliably, and not influence user's viewing experience.
In order to solve the problems of the technologies described above, the invention provides a kind of storage and update method of browsers local page, may further comprise the steps:
(a) to the arbitrary local page in the local page system that has " tree " structure in the browser, arbitrary node in promptly setting, write down its unique structural identification and version identifier, comprise the node number information of each node on the path from root node to this node in the structural identification; And the structural identification and the version identifier that comprise the child node of this node sensing in the local links of local page;
Simultaneously, store this local page system that adopts same way as sign local page on the server in the network, and store the outside page with another system;
(b) after the user clicks external linkage in the local page, browser is sent out upstream request, require to download the respective external page, in this request, except that the target external page iden-tity, also have the structural identification and the version identifier of each node on the path from root node to this local page node;
(c) after server is received this upstream request, on the more described one by one in order path each node in request version identifier and the version identifier on the server, if find to have different persons, the local page that first version on the path is different on server structural identification and version identifier as modification information and page data or/and information is sent back to browser together;
(d) after browser is received downlink information, if modification information is arranged, find the local links that comprises this structural identification in the father node of its node pointed according to wherein structural identification, replace version identifier in this local links with the version identifier in the modification information then, and handle and show described page data and/or information; Otherwise, only need to handle and show described page data and/or information;
(e) browser judges according to structural identification in the local links on the local page and version identifier whether its indication local page does not exist maybe needs replacement, if, then from current data and the structural identification and the version identifier of this local page of downloaded, finish storage or replacement, and deletion no longer is replaced the local links following one deck local page pointed on the local page of back.
Further, above-mentioned storage and update method also can have following characteristics: described step (e) further may further comprise the steps:
(e1) browser judges according to the structural identification in the local links whether the local page of indication exists, if there is execution in step (e2), if there is no, then send out upstream request and require to increase this local page, carry this local page structural identification, execution in step (e3);
(e2) browser judges whether the version identifier in this link equals the version identifier of indication local page, if, local page pointed is shown to the user, finish; Otherwise, send out upstream request and require to replace this local page, carry this local page structural identification, execution in step (e3);
(e3) after server is received the request of up " replacement " or " increase " local page, issue current data, structural identification and the version identifier of this local page of newly-increased or new edition to this browser;
(e4) after browser is received above-mentioned downlink information, there is not this page in the local page system if judge according to structural identification wherein, execution in step (e5), otherwise, execution in step (e6);
(e5) browser is stored the local page data of receiving, and compare with the version identifier in corresponding link the on the version identifier in the downlink information and this local page father node, if it is different then replace old version identifier in the link with the version identifier in the downlink information, end.
(e6) browser overrides former page data with the local page data of receiving, and compare with the version identifier in corresponding link the on the version identifier in the downlink information and this local page father node, if different with the version identifier in the downlink information replace link in old version identifier, deletion no longer is replaced the local links following one deck local page pointed on the local page of back then, finishes.
Further, above-mentioned storage and update method also can have following characteristics: in the described step (e1), browser is when the user clicks a local links, the judgement whether initiation exists structural identification indication local page in this local links, and show the described local page of downloading in step (e5) and (e6); Perhaps, browser is noted the local links revised and the local page node at place thereof in step (d), then setting opportunity set by step the mode of (e1)~(e6) local links of each local page of noting is handled.
Further, above-mentioned storage and update method also can have following characteristics: described step (c) server judges also whether last local page does not exist on the described path in server local page tree, even or also exist but point to the link that institute asks the outside page of download, if, the data of then that first version is different local pages and the information that menu structure has been revised are returned browser, otherwise, target external page data or the inaccessible abnormal prompt information of this target external page are returned browser; In the described step (d), the information of browser as receiving that menu structure has been revised, then replace old local page data with the new local page data of receiving, and deletion no longer is replaced the local links following one deck local page pointed on the local page of back, then this information is shown to the user, browser then shows, handles this target external page data or abnormal prompt information as receiving outside page data or the inaccessible abnormal prompt information of this target external page.
Further, above-mentioned storage and update method also can have following characteristics: in the described step (e), the visit device judges also whether the version identifier in corresponding the link is different on version identifier and this local page father node of local page of download, not not simultaneously, replace old version identifier in the corresponding link with this version identifier of downloading.
Further, above-mentioned storage and update method also can have following characteristics: the depth value N that also comprises node place layer in the described structural identification, the node number information of each node is that the node number number of arranging according to the order of sequence and this structural identification comprises equals the number of plies that " tree " structure has in the structural identification, and this depth value N is used for indicating N node number of node number sequence front effective; Perhaps, the node number information of each node is arranged in a node number sequence according to the order of sequence in the described structural identification, and is also comprising one not by the employed end mark of node number thereafter.
Further, above-mentioned storage and update method also can have following characteristics: the number of plies that the local page system of described " tree " structure comprises is 3 grades, 6 grades or 9 grades, and the maximum son node number that each grade comprises is 4,8,16 or 32.
Further, above-mentioned storage and update method also can have following characteristics: in the described step (b), the number of plies that comprises this local page node place in tree in the upstream request that browser sends, and the structural identification and the version identifier of each node on the path from root node to this node; Perhaps, comprise this local page node structure sign in this upstream request, and the version number of each node on the path from root node to this node of arranging in order.
Further, above-mentioned storage and update method also can have following characteristics: set up a updating mark for root node specially in the browser, in the described step (d), when the structural identification in the browser discovery modification information refers to root node, then with this flag set; And in the described step (e), when browser finds that this updating mark is set, then send out the local page data that upstream request requires to download this root node correspondence, override the old page then, and its child node is cleared up.
Further, above-mentioned storage and update method also can have following characteristics: described browser is for being bearer path with the note, by the microbrowser of gateway access webserver content.

Embodiment
Go up the browser (abbreviating the SIM browser as) that uses with SIM below and be example, the present invention will be described in conjunction with the accompanying drawings.It is a kind of be bearer path with the note, by the microbrowser of gateway access webserver content.
Usually, in the SIM browser, the local page system has typically " tree " structure, in " tree " each " node " all is a local page, the first order master menu page is " tree " " root node ", each Level-2 menu page all is " child node " of " root node ", and " root node " is otherwise known as their " father node ", and the like to following local page nodes at different levels.It is pointed that each " child node " all comprised at least one local links by its " father node ", when the user browsed " father node " and selected a local links, " child node " that the SIM browser just finds this link to point in the storage of this locality showed.Local page also can comprise external linkage, and when the user selected this link, browser sent upstream request, requires to download an outside page of not storing in this locality.
In the present embodiment, each local page in " tree " structure identifies by a SV-ID (Structureand Version ID, structure and version identifier), as depicted in figs. 1 and 2.The SV-ID of each local page of present embodiment takies 4 bytes, comprises two parts: structural identification S-ID and version identifier V-ID.
V-ID is with a byte representation, and scope from 0 to 255 can certainly get 0 to 128, or 0 to 1024 (this moment, V-ID needed two bytes) or the like other value.The revision ID of first published is 0, and its V-ID of new edition of later every renewal adds 1, and the version number of example is 10 among the figure.
S-ID is identified by the path from root node to it by its determining positions in whole local page tree.Consider the SIM capacity, present embodiment has been done following restriction to the local page tree when realizing: the local page tree comprises 5 node layers at most; Each node comprises 16 child nodes at most.But be not limited thereto in other embodiment, the number of plies and maximum child node number can be determined voluntarily by the deviser or the implementor of system.For example: the number of plies is 3 grades, 6 grades or 9 grades, and the son node number that each grade comprises is 4,8,16 or 32, determines a kind of S-ID form of relatively saving the space then.
As shown in the figure, S-ID is made up of the depth value of node place layer and the node number sequence on the path from root node to this node.Depth value accounts for 4 bits.The node number sequence comprises 5 node numbers, and each node number accounts for 4 bit.For example, the degree of depth of root node is 1, and the node number sequence is 0; The degree of depth of first node of the second layer is 2, and the node number sequence is 0.0; The degree of depth of second node of the second layer is 2, and the node number sequence is 0.1, and the degree of depth of the 3rd child node (the 3rd node layer) of second node of the second layer is 3, and the node number sequence is 0.1.2, and the like.During processing, at first check depth value, the front in 5 node numbers of determining thus to follow later is several to be effective.For example,, then in the node number sequence, have only 3 node numbers in front effective if depth value is 3, no matter the 4th and the layer 5 node number be that what value is all meaningless.
Also there is other method for expressing in S-ID.For example, do not use layer depth, but when the 4-bits of node number sequence represents to finish, adding the end mark of a 4-bits thereafter, as with 0 or F as end mark.When reading end mark, handling procedure knows just that some 4-bits of end mark front constitute effective node number sequence.When adopting this method, regulation allow the numerical value that end mark takies (as 0 or F), can not be used by node number again.
Like this, can local page of unique identification by SV-ID, therefore the SV-ID that just quotes by this page to local page realizes.Among the present invention, local links adopts that (TEXT SV-ID) replaces that commonly used (TEXT, URL) mode are promptly indicated a certain local page with SV-ID, and TEXT is illustrated in the literal that shows on the page menus.
Usually, when the user bought SIM, the SIM browser in the card had stored the tree of a complete local page, and server end also stores the local page tree of corresponding construction.When needs upgraded, the page versions upgrading as server end had increased the new page or has deleted original page, just needs to realize the synchronous renewal of local page on the SIM browser.Among the present invention, renewal is to finish jointly by process of visiting the outside page and the process of browsing local page.In the present invention, the outside page is stored in another autonomous system of server, and identifies with the outside page ID of one 4 byte, and the separate running of SV-ID of it and local page can not be obscured.
The process of visiting the outside page may further comprise the steps as shown in Figure 3:
Step 110, when the user clicked external linkage in the local page, browser was sent out upstream request, required to download the corresponding outside page.Except containing the target external page ID, also comprise the structural identification information and the version number information of each node on the path from root node to this local page node in this request;
Carry the meaning of the structural identification and the version information of path node, be to allow server check whether the local page that needs renewal is arranged on this path in good time.In the present embodiment, the information of this path node is by on the path from root node to this local page node, the SV-ID of each node (comprising this local page self) provides, be called the N-SVID structure of local page in the literary composition, suppose on this path total N node, then this structure successively by the SV-ID2 of the 2nd node on the SV-ID1 of the 1st node on the number of plies of click local page node in tree, the path, the path ..., the SV-IDN composition of N node on the path.
Note, because server promptly can be extrapolated the intermediate node of its process from last SV-ID, in another embodiment, also this beacon information can be reduced to S-ID by last node and add on the path from root node to this local page node each rearranging in order through the version number of node.
Step 120, after the webserver is received described upstream request, according to the information of path node wherein, from root node, one by one the V-ID of current corresponding node on the V-ID of each node on the path and the server is compared in order, if finding has different persons, then the SV-ID of first different persons (referring to the local page that first version is different) on server on the path noted;
Step 130, the webserver judges whether that last the local page node among the N-SVID does not exist in server local page tree, even or also exist, but no longer contained the link of the outside page that the outside page ID of definite object identified therein, if, execution in step 140, otherwise, execution in step 170;
Step 140, the local page data that SV-ID identified that the webserver will be noted are just now taken out from server, add information " the local page menu structure is revised; enter new menu by the OK key " in its front, and with this SV-ID as modification information, one removes and passes to the SIM browser;
Step 150, after the SIM browser receives that front that the webserver returns has added the new local page of " menu structure is revised " information, at first replace old page data with identical SV-ID with new local page data, the corresponding V-ID that links with its father node of V-ID with SV-ID in the modification information compares then, if it is different then replace old V-ID in corresponding the link with the V-ID in the modification information, then the child node of replacing posterior nodal point is cleared up, at last information is shown to the user, when the user presses " OK " key, again new page is shown to the user, finishes;
During the cleaning child node, one by one to replace the back in the local page local links and be that the child node of father node is checked to replace posterior nodal point, in the local page of looking at just to have replaced, whether also comprise the local links that points to these child nodes, delete those and no longer be replaced the child node that the back local links points to.
Step 160, just now the SV-ID that noted is sent back to the SIM browser together as the modification information (if any) of local page and target external page data (in the time of can finding this page) or the abnormal prompt information (in the time of can't finding this page) such as " the outside page of being asked do not exist ... " that need return;
Step 170, after the SIM browser is received the downlink information that the webserver returns, judge whether to contain the modification information of local page earlier, if have then local links relevant in the father node of SV-ID node pointed in the modification information made amendment, processing then, the outside page of display-object or abnormal prompt information, if do not revise information, then directly processing, the outside page of display-object or abnormal prompt information finish.
When revising in the father node local links, earlier find out its father node according to the S-ID in the modification information (being contained among the SV-ID), in the content of pages of father node, inquire about all local links then, find out the local links that contains S-ID in the information, replace with the revision ID in the modification information then and find the revision ID in the SV-ID in the link.
In another embodiment, if step 130 webserver is judged last the local page node among the N-SVID and is not existed in server local page tree, though or exist but the link of the outside page that do not had to be asked also can only send to the SIM browser with " menu structure is revised " as abnormal prompt information and modification information together.After the SIM browser is received set by step 170 mode handle.So also can finish the renewal of local page system, but the processing of embodiment is more humanized.
From above-mentioned flow process as can be seen, present embodiment carries the version information of local page on the associated pathway in the upstream request of the outside page of visit, and server can use the version information of the local page of this information and self preservation to compare.Even some node of server is updated on this path, in order not interrupt user's normal use flow process as far as possible, as long as also comprise target external page link (renewal of node does not directly have influence on by the outside page of this paths access destination on this explanation path) corresponding to the local page of initiating request on the server, when returning the page info of request, return so and revise prompting, this prompting does not comprise the data that will upgrade the page, and include only the version number that will upgrade the page, SIM browser operation bidirectional at this moment only is that this version number is copied in the correspondence link of father node.Can not influence the processing time that the user this time operates like this, can avoid because of upgrading the access delay that a plurality of pages bring.
Only cause (for example becoming under impossible situation by this path access target external page in the renewal of server local page node, the local page that sends request does not exist in server local page tree, or it has been changed under other node as child node, or its content has changed into about other field and aspect etc.), just will pass to browser under process local page of revising the earliest on the access path, and point out the user to use the local page after the renewal to begin thus.
Notice that the correspondence link on the father node of modification local page node is inapplicable to root node, because root node does not have father node.For this reason, the present invention has set up a updating mark for root node specially in the SIM browser. and find the SV-ID in the local page modification information when the SIM browser and refer to root node, then with this flag set.Certainly, for the situation that root node need not to revise, the root node updating mark then is in the state that is not set.
The menu item that the root node of local page tree inserts mobile phone by SETUP MENU order activates, and all the other nodes are all pointed by a local links in its father node.The process of browsing local page may further comprise the steps as shown in Figure 3:
Step 210, when the user clicks a local links, browser judges according to the S-ID in the SV-ID in the link whether the local page of indication exists, if existence, execution in step 220, if there is no, execution in step 250;
Step 220 further judges whether the V-ID in the link equals the V-ID of indication local page, if, illustrate that this local page need not replace, execution in step 230, otherwise, illustrate that this local page needs to replace execution in step 240;
Step 230, the local page pointed local links is shown to the user, finishes;
Step 240, the SIM browser is sent out upstream request, carries the SV-ID of this local page that needs replacement and requires to replace this local page, execution in step 260;
In another embodiment, this upstream request can be included in the N-SVID structure of the local page that needs replacement, and server can check once more whether the local page that needs replacement is arranged on the path.
Step 250, the SIM browser is sent out upstream request, carries the SV-ID of this local page and requires to increase this local page, execution in step 260;
Step 260, after server is received the request of up " replacement " or " increase " local page, issue corresponding page data to this SIM browser, this downlink information is the local page of a newly-increased or new edition, the S-ID that identifies among the SV-ID of this page is identical with S-ID in the request, and V-ID is then with the up-to-date V-ID on the server;
Whether step 270 after the SIM browser is received above-mentioned downlink information, is searched this page according to its S-ID and is existed in the local page system, if there is no, and execution in step 280, otherwise, execution in step 290;
Step 280, the local page data that the storage earlier of SIM browser is received, the corresponding V-ID that links with father node of V-ID with SV-ID in the information compares then, if difference then old V-ID in linking with the replacement of the V-ID in the downlink information, show this page at last, finish;
Step 290, the SIM browser overrides old page data with new local page data, the corresponding V-ID that links with father node of V-ID with SV-ID in the information compares then, if different with the V-ID in the downlink information replace link in old V-ID, then the child node of replacing posterior nodal point is cleared up, again new page is shown to the user at last, finishes.
In another embodiment, in browsing the local page process, can temporarily the child node of replacing posterior nodal point not cleared up yet, just writing down which local node was replaced in this uses, can concentrate on sometime then, when starting browser next time as the user, local links on each node of record is checked unified the cleaning.
In addition, in order to finish the renewal of root node, each user starts the SIM browser, and browser all can at first be checked local page root node updating mark, if this sign is set, browser is sent out upstream request, requires to upgrade root node.After receiving the root node catalogue, replace the old page, carry out the child node cleaning by top description then, at last the homepage information after upgrading is shown to the user with the new page.Because root node does not have father node, so in upgrading the root node process, need not to detect this step of local links V-ID in the father node.
As can be seen, can realize the renewal of the page by this flow process, be dispersed in the operation of clicking local links owing to upgrade operation that it is very limited to upgrade consumed time each time, the user is on experiencing and to browse difference normally little.In addition, unsuccessful even certain of SIM browser upgrades operation, also can finish renewal, thereby improve reliability of updating by operating next time.
On the basis of the foregoing description, the present invention can also have various conversion:
For example, in another embodiment, after having revised the version number of corresponding local links in the father node that needs to upgrade local page by the process of visiting the outside page, can note the local page node at these local links revised and place thereof, and then these nodes are unified to handle, processing can start browser the user next time, this closes browser or the user chooses a certain menu or other opportunity to carry out.Processing mode is identical with embodiment, promptly when the node that certain was revised is handled, browser judges according to structural identification in the local links on the local page and version identifier whether its indication local page does not exist maybe needs replacement, if, then from current data and the structural identification and the version identifier of this local page of downloaded, finish storage or replacement, and deletion no longer is replaced the local links following one deck local page pointed on the local page of back, simultaneously the version identifier in corresponding the link is not simultaneously on the version identifier of downloading and this local page father node, replace old version identifier in the link with the version identifier of downloading, but need not be presented at the page of downloading in this process.
For example, the SIM browser that the present invention mentions, can also be used for the UIM browser and other is the microbrowser of bearer path with the note in can be applicable to embodiment.
