Incremental upgrade method, apparatus for applying method and storage medium

TECHNICAL FIELD

0001The present invention relates to the field of data transmission processing technologies, and in particular, to an incremental upgrade method, an apparatus applying the method and a storage medium.

BACKGROUND

0002Version upgrade refers to an update for removing bugs in an operating system or an old version of software, or adding a new application function to software, to make software more perfect and useful.

0003When a terminal performs version upgrade on a local old version file, the terminal needs to acquire data information of a new version from a server. Assuming that an installation package file of a local old version on the terminal is old.apk having a size of 5M, and an installation package file of a new version that needs to be acquired is new.apk having a size of 6M, in a conventional version upgrade technology, the new.apk having the size of 6M needs to be downloaded to complete the version upgrade.

0004However, this conventional version upgrade method needs to download a complete new version of installation package file from the server, the size of downloaded data is large, and an excessive bandwidth resource may be occupied.

0005Therefore, a downloading and upgrade technology for reducing data transmission size during version upgrade is needed, to reduce occupied bandwidth resources.

DETAILED DESCRIPTION

0065In order to make a person skilled in the art better understand technical solutions in the embodiments of the present invention, and make the above objectives, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further details with reference to the accompanying drawings.

0066In the following descriptions, many specific details are described to provide thorough understanding on one or more embodiment for the sake of illustration. However, apparently, the embodiments may also be implemented without the specific details. In other examples, well-known structures and devices are shown as block diagrams to describe one or more embodiments.

0067<figref idref="DRAWINGS">FIG. 1</figref> shows a process of an incremental upgrade method according to an embodiment of the present invention.

0068As shown in <figref idref="DRAWINGS">FIG. 1</figref>, from the perspective of a terminal side receiving an incremental upgrade package, the incremental upgrade method provided in one embodiment of the present invention includes the following steps:

0069Step <b>101</b>: A terminal sends a request to a server for downloading an incremental upgrade package corresponding to a local old version file on the terminal.

0070In this embodiment, after acquiring relevant information of the incremental upgrade package on the server, the terminal may send a request to the server for downloading the incremental upgrade package corresponding to the local old version file on the terminal. The terminal may also send a download request to the server without knowing whether there is an incremental upgrade package on the server. The request includes identification information or association information of the incremental upgrade package needed by the terminal, such as old version file information corresponding to the incremental upgrade package stored on the terminal, so that the server accordingly acquires the incremental upgrade package that needs to be downloaded.

0071Step <b>102</b>: The terminal receives the incremental upgrade package from the server.

0072The incremental upgrade package includes unmatched block data obtained by comparing a first compressed file and a second compressed file and the start and end information of the unmatched block data, where the second compressed file is a compressed file of the old version file, and the first compressed file is a compressed file that concatenates the old version file and a new version file. By means of the unmatched block data and the start and end information thereof, the terminal can concatenate a new upgrade version on the basis of the compressed file of the original old version.

0073After receiving the download request, the server may search, according to information in the request, to see whether the server locally has the incremental upgrade package, and if yes, directly sends it to the terminal; if no, generates the incremental upgrade package and then sends it to the terminal.

0074Specifically, an exemplary process of the server generating the incremental upgrade package may be that: the server concatenates the old version file and the new version file and then compresses the concatenate file to obtain a first compressed file, and compresses the old version file to obtain a second compressed file, then compares the first compressed file with the second compressed file to obtain unmatched block data and the start and end information of the unmatched block data, and finally generates the incremental upgrade package according to the unmatched block data and the start and end information of the unmatched block data. The unmatched block data is the difference between the old version and the corresponding new version.

0075There may be several manners for the server to obtain the old version file and the corresponding new version file, such as acquiring locally, or downloading and acquiring online, etc.

0076Step <b>103</b>: The terminal concatenates the unmatched block data and the local second compressed file (compressed from the local old version file) according to the start and end information of the unmatched block data in the incremental upgrade package, to generate a concatenate compressed file.

0077After acquiring the incremental upgrade package, the terminal obtains the new version file by using a reverse process of the server generating the incremental upgrade package. Specifically, in this step, the terminal first concatenates, according to the start and end information of the unmatched block data, the unmatched block data and the compressed file of the local old version file on the terminal, i.e., the local second compressed file of the terminal, to obtain the concatenate compressed file, and the concatenate compressed file is actually the first compressed file obtained at the server side.

0078Because it is a file upgrading procedure, the old version file that needs to be upgraded is in the terminal, and generally, the compressed file of the old version file (that is, the second compressed file) can also be stored on the terminal locally. Therefore, the unmatched block data in the incremental upgrade package may be directly concatenated with the local second compressed file to obtain the concatenate compressed file (that is, the first compressed file, i.e., the compressed file including the new version file to be used for upgrading). If the terminal does not have the second compressed file locally, the terminal may also obtain the second compressed file according to the local old version file on the terminal by using a known data processing manner. This data processing manner is in the prior art and is not the focus of the technical processing of the present invention, and therefore, it is not elaborated herein.

0079Step <b>104</b>: The terminal decompresses the concatenate compressed file to obtain the new version file.

0080After the terminal decompresses the concatenate compressed file, the terminal may obtain the new version file corresponding to the old version file to be upgraded.

0081From the perspective of upgrading data transmission, the terminal is capable of implementing the incremental upgrade at the terminal side upon obtaining the new version file corresponding to the old version file to be upgraded. Then, the terminal may upgrade the original old version file according to the new version file.

0082The upgrade process of this step is similar to the prior art, and is not elaborated herein.

0083In the embodiment shown in <figref idref="DRAWINGS">FIG. 1</figref>, the terminal obtains an incremental upgrade package from a server side, and obtains a new version file according to the incremental upgrade package, thereby implementing incremental upgrade; moreover, the incremental upgrade package merely includes unmatched block data information between a compressed file that concatenates a new version file and an old version file and a compressed file of the old version file, which has a greatly reduced data size compared with the complete new version file data, and therefore, the size of data that needs to be downloaded by the terminal from the server is obviously less than the conventional method. The method reduces data traffic, reduces occupied bandwidth resources, greatly accelerates the version upgrade, improves the efficiency of version upgrade, and saves storage medium resources of the server.

0084<figref idref="DRAWINGS">FIG. 2</figref><i>a </i>shows a flow of an incremental upgrade method according to another embodiment of the present invention, and the process also performs incremental upgrade data processing from the perspective of the terminal side.

0085As shown in <figref idref="DRAWINGS">FIG. 2</figref><i>a</i>, the incremental upgrade method in this embodiment includes the following steps:

0086Step <b>201</b>: A terminal sends a search request to a server, the search request including version information of an old version file that needs to be upgraded.

0087The terminal may send a request of searching for an incremental upgrade package to the server periodically or at a preset time, and the search request may include version information of the old version file, for example, V1.1.0, to facilitate the server searching for a corresponding upgrade package and the like.

0088After receiving the search request, the server searches for the incremental upgrade package according to the search request. If at this time the server has generated the incremental upgrade package between the new version file and the old version file, description information of the incremental upgrade package may be extracted; and if no incremental upgrade package is generated, the server generates an incremental upgrade package temporarily after finding the new version file and the old version file locally. No matter whether the incremental upgrade package is generated in advance or not, the generation process may use the method of the server generating the incremental upgrade package in step <b>102</b> in the embodiment shown in <figref idref="DRAWINGS">FIG. 1</figref>.

0089<figref idref="DRAWINGS">FIG. 2</figref><i>b </i>shows an example of generation of an incremental upgrade package according to an embodiment of the present invention. Assuming that the terminal side has an old version file old.apk that has the size of 5M and needs to be upgraded to a new version file, and the server side has the old version file old.apk and a new version file new.apk that has the size of 6M.

0090When the server generates the incremental upgrade package, the server first compresses old.apk to obtain old.7z (a compressed file of an old version) that has the size of 2M; concatenates old.apk and new.apk, then compresses the concatenate file to obtain old_new.7z (a concatenate compressed file) that has the size of 2.2M, and compares old.7z with old_new.7z, as shown in <figref idref="DRAWINGS">FIG. 2</figref><i>b</i>, to obtain unmatched block data and the start and end information of the unmatched block. In <figref idref="DRAWINGS">FIG. 2</figref><i>b</i>, the dashed area indicates the same data, and blank area indicates different data in two compressed files of old.7z and old_new.7z. That is, the unmatched block data, and the start and end information of the unmatched block data may also be obtained through comparison, and the incremental upgrade package generated at the server side includes the unmatched block data and the start and end information thereof and has the size of about 1M; therefore, the terminal merely needs to download the incremental upgrade package having the size of 1M, and the download size is greatly reduced.

0091The server feeds back the description information of the incremental upgrade package to the terminal, and can also feedback version information of the new version file or the like, where the description information of the incremental upgrade package may specifically be identification information such as a name of the incremental upgrade package.

0092Step <b>202</b>: The terminal receives the feedback information of the server, the feedback information including the description information of the incremental upgrade package.

0093Step <b>203</b>: The terminal sends, according to the description information of the incremental upgrade package in the feedback information, a request to the server for downloading the incremental upgrade package.

0094Step <b>204</b>: The terminal receives the incremental upgrade package.

0095Step <b>205</b>: The terminal concatenates the unmatched block data and the local second compressed file according to the start and end information of the unmatched block data in the incremental upgrade package, to generate a concatenate compressed file.

0096Assuming that after the terminal receives the unmatched block data of the two compressed files of old.7z and old_new.7z and the start and end information thereof, the terminal concatenates the unmatched block data and the local old.7z according to the start and end information of the unmatched block data, where the concatenation process is restoring the old_new.7z as shown in <figref idref="DRAWINGS">FIG. 2</figref><i>b. </i>

0097Step <b>206</b>: The terminal decompresses the concatenate compressed file to obtain the new version file.

0098The terminal decompresses the old_new.7z obtained through concatenation in the previous step, to obtain the new version file new.apk corresponding to the old version file old.apk.

0099Step <b>207</b>: The terminal upgrades the original old version file old.apk according to the new version file new.apk.

0100The steps <b>204</b> to <b>207</b> are similar to the steps <b>102</b> to <b>105</b> in the previous embodiment, and are not repeated herein.

0101In the embodiment shown in <figref idref="DRAWINGS">FIG. 2</figref><i>a</i>, the terminal obtains an incremental upgrade package at a server side, and obtains a new version file according to the incremental upgrade package, thereby implementing incremental upgrade; moreover, the incremental upgrade package merely includes unmatched block data information between a compressed file that concatenates a new version file and an old version file and a compressed file of the old version file, which has a greatly reduced data size compared with the complete new version file data, and therefore, the size of data that needs to be downloaded by the terminal from the server is obviously less than the conventional method. The method reduces data traffic, reduces occupied bandwidth resources, greatly accelerates the version upgrade, improves the efficiency of version upgrade, and saves storage medium resources of the server.

0102<figref idref="DRAWINGS">FIG. 3</figref> shows a process of an incremental upgrade method according to yet another embodiment of the present invention.

0103As shown in <figref idref="DRAWINGS">FIG. 3</figref>, from the perspective of a server side sending an incremental upgrade package, the incremental upgrade method provided by the present invention includes:

0104Step <b>301</b>: A server compresses an old version file to obtain a second compressed file, and concatenates the old version file and a new version file and then compresses the concatenate file to obtain a first compressed file.

0105In this embodiment, no matter whether the server receives a search request or a request for downloading an incremental upgrade package sent by the terminal, an incremental upgrade package may be generated first by using steps <b>301</b> to <b>303</b>.

0106In this step, the server first concatenates the local old version file and the new version file, the concatenation being connecting data of the old version file and data of the new version file with the old version prior to the new version, and then compresses the concatenate file to obtain a first compressed file; the server compressed the old version file separately to obtain a second compressed file. The process of obtaining the first compressed file and the process of obtaining the second compressed file may be performed simultaneously, or may be performed according to a certain order.

0107Step <b>302</b>: The server compares the first compressed file with the second compressed file to obtain unmatched block data and the start and end information of the unmatched block data.

0108The server compares the first compressed file and the second compressed file, determines the data content difference between the two files as the unmatched block data, and records the start and end points information of the data content difference.

0109Step <b>303</b>: The server generates an incremental upgrade package according to the unmatched block data and the start and end information of the unmatched block data.

0110Step <b>304</b>: The server receives a request sent by the terminal for downloading the incremental upgrade package.

0111Step <b>305</b>: The server sends the incremental upgrade package to the terminal.

0112The terminal concatenates the unmatched block data and the local second compressed file, i.e., the compressed file of the old version file according to the start and end information of the unmatched block data in the incremental upgrade package, to generate the concatenate compressed file, decompresses the concatenate compressed file to obtain the new version file, and upgrades the old version file according to the new version file.

0113In the embodiment of the present invention, the server generates an incremental upgrade package according to the unmatched block data information between the compressed file that concatenates the old version file and the new version file and the compressed file of the old version file, so that the terminal obtains the new version file according to the incremental upgrade package, thereby implementing incremental upgrade. The incremental upgrade package has a greatly reduced data size compared with the complete new version file data, and therefore, the size of data that needs to be downloaded by the terminal from the server is obviously less than the conventional method. The method reduces data traffic, reduces occupied bandwidth resources, greatly accelerates the version upgrade, improves the efficiency of version upgrade, and saves storage medium resources of the server.

0114In another embodiment, before the old version file and the new version file are concatenated and then the concatenate file is compressed to obtain the first compressed file at the server side, and the old version file is compressed to obtain the second compressed file at the server side, the method may further include:

0115the server receives a search request sent by the terminal, the search request including version information of the old version file;

0116the server searches for the old version file and the new version file according to the version information of the old version file in the search request;

0117the server concatenates the old version file and the new version file and then compresses the concatenate file to obtain the first compressed file, and compresses the old version file to obtain the second compressed file. The concatenating and compressing steps may include:

0118concatenating, by the server, the old version file and the new version file found locally and compressing the concatenate file to obtain the first compressed file, and compressing the old version file to obtain the second compressed file.

0119In this embodiment, the server may generate the incremental upgrade package in advance before receiving the request sent by the terminal for downloading the incremental upgrade package, specifically, after the search request sent by the terminal is received, or after the server obtains the new version file.

0120In another embodiment, the server may generate the incremental upgrade package after receiving the request for downloading the incremental upgrade package, and specifically, as shown in <figref idref="DRAWINGS">FIG. 4</figref>, the method may include:

0121Step <b>401</b>: The server receives the request sent by the terminal for downloading the incremental upgrade package, the request including version information of the old version file corresponding to the incremental upgrade package.

0122No matter whether the server has the incremental upgrade package, the terminal can send, at a fixed time or periodically, the request to the server for downloading the incremental upgrade package, and the request may include the version information of the old version file corresponding to the needed incremental upgrade package, so that the server searches for the corresponding incremental upgrade package according to the information.

0123Step <b>402</b>: The server searches for the old version file and the new version file according to the version information of the old version file in the request.

0124After receiving the request, the server searches for the corresponding new version file according to the version information of the old version file in the request.

0125Step <b>403</b>: The server concatenates the old version file and the new version file and then compresses the concatenate file to obtain a first compressed file, and compresses the old version file to obtain a second compressed file.

0126Step <b>404</b>: The server compares the first compressed file with the second compressed file to obtain unmatched block data and the start and end information of the unmatched block data.

0127Step <b>405</b>: The server generates an incremental upgrade package according to the unmatched block data and the start and end information of the unmatched block data.

0128In the steps <b>403</b> to <b>405</b>, the process of the server generating the incremental upgrade package is the same as that in the foregoing embodiment.

0129Step <b>406</b>: The server sends the incremental upgrade package to the terminal.

0130The terminal concatenates the unmatched block data and the local second compressed file according to the start and end information of the unmatched block data in the incremental upgrade package, to generate a concatenate compressed file, and decompresses the concatenate compressed file to obtain the new version file, and upgrades according to the new version file.

0131In the embodiment shown in <figref idref="DRAWINGS">FIG. 4</figref>, the server generates an incremental upgrade package according to the unmatched block data information between the compressed file that concatenates the old version file and the new version file and the compressed file of the old version file, so that the terminal obtains the new version file according to the incremental upgrade package, thereby implementing incremental upgrade. The incremental upgrade package has a greatly reduced data size compared with the complete new version file data, and therefore, the size of data that needs to be downloaded by the terminal from the server is obviously less than the conventional method. The method reduces data traffic, reduces occupied bandwidth resources, greatly accelerates the version upgrade, improves the efficiency of version upgrade, and saves storage medium resources of the server.

0132In the descriptions of the embodiments, a 7zip method is utilized for compression of both the new version file and the old version file, and definitely, the compression algorithm is not limited to the 7zip, and may also include all other algorithms having the same characteristics. The above descriptions are made on the method embodiments of the present invention, and apparatuses implementing the above methods are described with reference to <figref idref="DRAWINGS">FIG. 5</figref> to <figref idref="DRAWINGS">FIG. 7</figref>.

0133<figref idref="DRAWINGS">FIG. 5</figref> shows a structure of a terminal applying an incremental upgrade method according to an embodiment of the present invention. As shown in <figref idref="DRAWINGS">FIG. 5</figref>, a terminal according to the embodiment of the present invention may include:

0143In this embodiment, the terminal first sends search request, by using the search requesting unit, to the server to see whether there is an incremental upgrade package, and if yes, according to the relevant information of the incremental upgrade package received by the information receiving unit, the upgrade package requesting unit requests for acquiring the incremental upgrade package.

0144<figref idref="DRAWINGS">FIG. 6</figref> shows a structure of a server applying an incremental upgrade method according to an embodiment of the present invention. As shown in <figref idref="DRAWINGS">FIG. 6</figref>, the server applying the incremental upgrade method provided in the present invention includes:

0145a compressing unit <b>601</b>, configured to concatenate an old version file and a new version file and then compress the concatenate file to obtain a first compressed file, and compress the old version file to obtain a second compressed file;

0150The server generates the incremental upgrade package by using the compressing unit <b>601</b>, the comparing unit <b>602</b> and the upgrade package generating unit <b>603</b>, the incremental upgrade package including the unmatched block data and the start and end information of the unmatched block data, and after the first request receiving unit <b>604</b> receives the request for downloading the incremental upgrade package, the upgrade package sending unit <b>605</b> sends the incremental upgrade package to the terminal, such that the terminal can perform incremental upgrade.

0151In another embodiment of the present invention, the server may further include:

0152a second request receiving unit, configured to receive a search request sent by the terminal before the compressing unit obtains the first compressed file and the second compressed file, the search request including version information of the old version file; and

0153a searching unit, configured to search for the old version file and the new version file according to the version information of the old version file in the search request;

0154wherein the compressing unit is configured to concatenate the old version file and the new version file found locally and then compress the concatenate file to obtain the first compressed file, and compress the old version file to obtain the second compressed file.

0155In this embodiment, after the second request receiving unit receives the search request and the searching unit founds the old version file and the new version file, the server may generate the incremental upgrade package by using the compressing unit <b>601</b>, the comparing unit <b>602</b> and the upgrade package generating unit <b>603</b>.

0156<figref idref="DRAWINGS">FIG. 7</figref> shows a structure of a server applying an incremental upgrade method according to another embodiment of the present invention. As shown in <figref idref="DRAWINGS">FIG. 7</figref>, a server according to the embodiment of the present invention includes:

0157a request receiving unit <b>701</b>, configured to receive a search request sent by a terminal for downloading an incremental upgrade package, the search request including version information of the old version file corresponding to the incremental upgrade package;

0158a searching unit <b>702</b>, configured to searching for an old version file and a new version file according to the version information of the old version file in the request;

0159a compressing unit <b>703</b>, configured to concatenate the old version file and the new version file and then compress the concatenate file to obtain a first compressed file, and compress the old version file to obtain a second compressed file;

0160a comparing unit <b>704</b>, configured to compare the first compressed file and the second compressed file to obtain unmatched block data and the start and end information of the unmatched block data;

0161an upgrade package generating unit <b>705</b>, configured to generate the incremental upgrade package according to the unmatched block data and the start and end information of the unmatched block data; and

0162an upgrade package sending unit <b>706</b>, configured to send the incremental upgrade package to the terminal, such that the terminal can concatenate the unmatched block data and the local second compressed file to generate a concatenate compressed file according to the start and end information of the unmatched block data in the incremental upgrade package, decompress the concatenate compressed file to obtain the new version file, and upgrade according to the new version file.

0163In this embodiment, after the request receiving unit <b>701</b> receives the request sent by the terminal for downloading the incremental upgrade package and the searching unit <b>702</b> finds the old version file and the new version file, the server may generate the incremental upgrade package by using the compressing unit <b>703</b>, the comparing unit <b>704</b> and the upgrade package generating unit <b>705</b>, and finally, the upgrade package sending unit <b>706</b> sends the incremental upgrade package to the terminal, such that the terminal can perform upgrade.

0164In the embodiment of the present invention, the server generates, through the abovementioned units, an incremental upgrade package according to the unmatched block data information between the compressed file that concatenates the old version file and the new version file and the compressed file of the old version file, so that the terminal obtains the new version file according to the incremental upgrade package, thereby implementing incremental upgrade. The incremental upgrade package has a greatly reduced data size compared with the complete new version file data, and therefore, the size of data that needs to be downloaded by the terminal from the server is obviously less than the conventional method. The method reduces data traffic, reduces occupied bandwidth resources, greatly accelerates the version upgrade, improves the efficiency of version upgrade, and saves storage medium resources of the server.
