All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present invention, where the implementation environment includes: a first terminal 101, a second terminal 102 and a server 103. Wherein a point-to-point communication connection is established between the first terminal 101 and the second terminal 102. The server 103 establishes network communication connections with the first terminal 101 and the second terminal 102, respectively. The first terminal 101 and the second terminal 102 have a download application installed thereon, and the first terminal 101 and the second terminal 102 perform data interaction with the server 103 based on the download application.
The first terminal 101 may be a terminal currently used by a user, the second terminal 102 may be a terminal that establishes a peer-to-peer communication connection with the first terminal 101, and the number of the second terminals 102 may be one or more. The first terminal 101 may send an acquisition request to the server 103 based on the number of terminals of the first terminal 101 and the second terminal 102 to acquire the target file. The first terminal 101 sends a first acquisition request to the server 103, and the second terminal 102 sends a second acquisition request to the server 103. The server 103 firstly segments the target file to obtain a plurality of file segments based on the first obtaining request of the first terminal 101 and the second obtaining request of the second terminal 102. The server sends a first file fragment of the plurality of file fragments to the first terminal 101 and sends a second file fragment of the plurality of file fragments to the second terminal 102. The first terminal 101 and the second terminal 102 share the first file fragment and the second file fragment based on point-to-point communication connection, and both the first terminal 101 and the second terminal 102 can obtain the first file fragment and the second file fragment and splice the first file fragment and the second file fragment to obtain the target file.
The peer-to-peer communication connection may be a local area network connection, a bluetooth connection, or an NFC (Near field communication, or the like). The first terminal 101 and the second terminal 102 may be any terminal with a downloading function, such as installing the downloading application or downloading a plug-in, which is not particularly limited in the embodiment of the present invention.
Fig. 2 is a signaling interaction diagram of a file acquisition method according to an embodiment of the present invention. The embodiment of the present invention is implemented by a first terminal and a server interactively, wherein the first terminal and at least one second terminal establish a peer-to-peer communication connection, referring to fig. 2, the method includes:
201. when the first terminal receives the acquisition instruction, the first terminal acquires the number of target terminals.
The number of target terminals refers to the total number of the first terminal and the at least one second terminal. When the first terminal detects that a target file in the plurality of files is selected, the first terminal receives an acquisition instruction, wherein the acquisition instruction is used for indicating to acquire the selected target file. The first terminal acquires the number of target terminals input in the current interface by the user.
It should be noted that, when the downloading application is started in the first terminal, the first terminal may display file identifiers of a plurality of files on a current display interface, the user may select a file to be downloaded from the plurality of files based on the file identifiers of the plurality of files, when the user selects a file identifier of a target file, the first terminal displays an input option on the current interface, and the first terminal obtains the number of target terminals input by the user in the input option. The target file may be an installation package of an application program, a video file, or other file.
202. And the first terminal sends a first acquisition request to the server based on the number of the target terminals and the file identification.
The first obtaining request is used for indicating the server to segment the target file based on the target terminal number and obtain a plurality of file segments. In this step, the first terminal may obtain the image identification code corresponding to the target terminal number and the file identification according to the target terminal number and the file identification, scan the image identification code, and send an acquisition request to the server.
The image identification code can be generated by any one of the first terminal or the at least one second terminal, and accordingly, the step can be implemented in the following two ways.
In the first method, the image identification code is generated by the first terminal, in this step, the first terminal generates the image identification code according to the number of the target terminals and the file identification, the first terminal displays the image identification code on a display interface, scans the image identification code, and sends the first acquisition request to the server, and the first acquisition request carries the number of the target terminals and the file identification.
Wherein the image identification code is used for indicating to send the acquisition request to the server. The first obtaining request carries the target terminal number and the file identification. The process of the first terminal scanning the image identification code and sending the first acquisition request to the server may be as follows: the image identification code carries the target terminal number and the file identification, the first terminal scans the image identification code, acquires the target terminal number and the file identification, and sends a first acquisition request to a server based on the indication of the image identification code. The image identification code can carry a script instruction, and the first terminal acquires the number of the target terminals and the file identification, executes the script instruction of the image identification code, and sends the first acquisition request to the server.
In a possible implementation manner, since a plurality of terminals need to send acquisition requests to the server, each terminal may correspond to one image identification code, and the first terminal generates a number of image identification codes equal to the number of target terminals according to the number of the target terminals, the file identification and the number of the image identification codes to be generated. The number of each image identification code to be generated is used for indicating the scanning sequence of the first terminal or each second terminal when the first terminal and the at least one second terminal scan the image identification codes in sequence. Then, the first terminal displays the plurality of image identification codes of the target terminal in a display interface, and the first terminal and the second terminal can sequentially scan the plurality of image identification codes of the target terminal and send an acquisition request to the server.
In a possible implementation manner, the first obtaining request may further carry file indication information of the first terminal, where the file indication information is used to indicate a storage condition and/or a transmission condition of a file fragment to be received. Step 202 may also be: the first terminal generates an image identification code according to the number of the target terminals, the file identification and the file indication information of the first terminal; the first terminal displays the image identification code in a display interface, scans the image identification code and sends the first acquisition request to the server.
The file indication information includes but is not limited to: the file size of the file fragment to be received does not exceed the target storage space of the first terminal, and/or the communication data volume for transmitting the file fragment to be received does not exceed the target communication data volume of the first terminal. The first terminal may obtain file indication information of the first terminal and file indication information of the second terminal in advance, and generate an image identification code of the first terminal and an image identification code of the second terminal, respectively, where the first terminal and the second terminal scan the image identification of the terminal.
The target storage space and the target communication data amount may be set based on needs, which is not specifically limited in this embodiment of the present invention. For example, the target storage space may be a remaining storage space currently remaining in the first terminal, and the target communication data amount may be a remaining communication data amount remaining in the first terminal in the current month.
In a second manner, the second terminal generates the image identification code, and this step may be: the first terminal scans the image identification code in the display interface of the at least one second terminal and sends a first acquisition request to the server.
The second terminal may be any one of the at least one second terminal. The image identification code in the display interface of the second terminal is the image identification code generated by the second terminal according to the file identification and the target terminal number, or the second terminal can also generate the image identification code according to the target terminal number, the file identification and the file indication information; and displaying the image identification code in a display interface for scanning by the second terminal and other terminals. The process of generating the image identification code by the second terminal is the same as the process of generating the image identification code by the first terminal, and is not repeated here.
The second terminal can display the image identification code in the display interface, and the first terminal sends the first acquisition request to the server by scanning the image identification code in the display interface of the second terminal. In addition, the process of the first terminal scanning the image identification code displayed by the second terminal is the same as the process of the first terminal scanning the image identification code displayed by the first terminal, and the description is omitted here.
In the embodiment of the present invention, the second terminal also sends a second acquisition request to the server. The process of sending the second acquisition request to the server by the second terminal is the same as the process of sending the first acquisition request by the first terminal, and is not described herein again.
203. The server receives a first acquisition request of the first terminal.
The first obtaining request carries a file identifier of a target file to be obtained and the number of target terminals of the target file. The server receives a first acquisition request of the first terminal, and acquires the file identifier and the number of target terminals from the first acquisition request. In addition, the server can also acquire the number of the image identification code and/or the file indication information of the first terminal from the first acquisition request. The server determines the sending sequence of the first terminal according to the number of the image identification code. In addition, the second terminal also sends a second acquisition request to the server by scanning the image identification code. The server may also receive a second acquisition request of the second terminal. The server may send the file fragments to the plurality of terminals in sequence according to the sending order of each terminal, with the scanning order of each terminal being the sending order of the file fragments to the plurality of terminals. For example, if the number of the image identification code scanned by the first terminal is 5, the scanning order of the first terminal is the fifth among the plurality of terminals. The server may send the file fragments to the first terminal 1 to 4 terminals in the scanning order as a sending order, and then send the file fragments to the first terminal.
204. And the server acquires the target file according to the file identifier in the first acquisition request.
The server stores a plurality of files in advance, and the first terminal acquires the target file according to the file identifier in the first acquisition request.
205. And the server divides the target file according to the number of the target terminals to obtain a plurality of file fragments.
The server divides the target file into a plurality of file fragments of which the number is equal to that of the target terminal according to the number of the target terminals.
In a possible implementation manner, the first obtaining request may further carry file indication information of the first terminal. The step can also be as follows: the server segments the target file into a plurality of file segments according to the file indication information and the number of the target terminals in the first acquisition request, wherein the plurality of file segments include a first file segment meeting the storage condition and/or the transmission condition of the first terminal, and the file indication information is used for indicating the storage condition and/or the transmission condition of the first terminal to-be-received file segments.
As shown in fig. 3, the server may segment a target file into file segments 1, 2, and … … based on acquisition requests of n terminals, and when performing file segmentation, the server may further perform segmentation in combination with file indication information of the terminals, so that each terminal can correspond to a file segment whose file size satisfies the storage condition and/or the transmission condition of the terminal.
It should be noted that the sizes of the file fragments are limited through the file indication information, the factors such as the storage space and the residual flow of each terminal are considered, and the file fragments with the proper sizes are segmented for each terminal, so that the accuracy of file segmentation is improved, the personalized requirements of different users are met, and the user experience is greatly improved.
206. And the server sends a first file fragment in the plurality of file fragments to the first terminal.
The server sends the first file fragment to the first terminal based on the terminal identifier of the first terminal, and sends a second file fragment of the file fragments to the at least one second terminal. And the second file fragments sent to each second terminal by the server are different. The first file fragment and the second file fragment are used for composing the target file. The server may further send, to the first terminal, location information of the first file segment in the target file, and send, to the second terminal, location information of the second file segment in the target file, so that each terminal may subsequently concatenate the plurality of file segments into a complete target file based on the location information of each file segment. The location information of each file fragment may be a storage location of the file fragment in the target file.
In a possible implementation manner, the first obtaining request may also carry the number of the image identification code scanned by the first terminal. Step 206 may also be: the server determines a file fragment with an arrangement sequence matched with the transmission sequence in the plurality of file fragments as the first file fragment according to the transmission sequence of the first terminal indicated by the serial number of the image identification code; and the server sends the first file fragment to the first terminal.
The arrangement order of each file fragment may be the arrangement order of the file fragments in the plurality of file fragments according to the storage location of each file fragment in the target file terminal. The server may determine, as the first file fragment, a file fragment of the plurality of file fragments that is arranged in the same order as the transmission order according to the transmission order of the first terminal.
In a possible implementation manner, the first obtaining request may further carry file indication information of the first terminal. The server determines a file fragment meeting the storage condition and/or the transmission condition of the first terminal from the plurality of file fragments as the first file fragment according to the file indication information of the first terminal, and sends the first file fragment to the first terminal. When the file indication information includes the storage condition of the first terminal, the server determines a file fragment with a file size not exceeding a target storage space of the first terminal among the plurality of file fragments as the first file fragment according to file sizes of the plurality of file fragments. When the file indication information includes the transmission condition of the first terminal, the server determines a file fragment with a file size not exceeding the target communication data volume of the first terminal among the plurality of file fragments as the first file fragment according to the sizes of the plurality of file fragments.
Wherein, the server also sends a second file fragment in the plurality of file fragments to at least one second terminal. The sending process is the same process as the process in which the server sends the first file fragment to the first terminal, and is not described herein again.
It should be noted that the server sequentially sends the file fragments with the arrangement sequence matched with the sending sequence to the plurality of terminals according to the sending sequence of the plurality of terminals and the arrangement sequence of the file fragments, so as to ensure the accuracy of file fragment transmission. In addition, the server divides the target file and sends the divided file fragments to each terminal, and compared with the prior art that each terminal acquires a complete target file from the server, in the embodiment of the invention, the server does not need to send the complete files to a large number of terminals one by one, especially when the file to be transmitted is large, so that the total data volume actually transmitted by the server is reduced, the waiting time of a user is reduced, and the user experience is improved.
207. And the first terminal receives the first file fragment sent by the server.
The first terminal may further receive location information of the first file fragment of the server. Of course, the second terminal also receives the second file fragment of the server.
208. The first terminal acquires the second file fragment from at least one second terminal.
The server sends the second file fragments to the at least one second terminal, wherein the second file fragments sent by the server to each second terminal are different, the first terminal sends a third acquisition request to the second terminal through the point-to-point communication connection based on the second terminal establishing the point-to-point communication connection with the first terminal, and the second terminal sends the second file fragments to the first terminal through the point-to-point communication connection when receiving the third acquisition request. And the first terminal receives the second file fragment through the point-to-point communication connection. In addition, the first terminal may further obtain the location information or the arrangement order of the second file segments from the second terminal.
And the first terminal sends the first file fragment to the second terminal according to the terminal identifier of the second terminal. The process of sending the first file fragment to the second terminal by the first terminal, which is the same process as the process of obtaining the second file fragment from the second terminal by the first terminal, is sent based on the point-to-point communication connection, and is not described herein again.
It should be noted that, as shown in fig. 4, in the conventional file acquiring process, the server needs to send a complete target file to each terminal, and even if the network transmission rate is high, it takes a long time for the server to transmit the whole target file. In contrast, in the embodiment of the present invention, the target file is divided into a plurality of file fragments by the server, and the file fragments are respectively sent to different terminals, without sending the whole target file, the file size of the file fragment sent to each terminal by the server is obviously much smaller than that of the whole target file, and when the transmission rate is 120k per second, the time spent on transmission is obviously reduced, so that the communication data volume of the terminal is greatly saved, and a user with more data traffic can assist the user with more data traffic, thereby realizing traffic resource sharing.
And the plurality of subsequent terminals can acquire other parts of the target file from other terminals of the point-to-point communication connection, and because the transmission rate of the point-to-point communication connection is far greater than that between the server and the terminals, the high-speed sharing of the file among the plurality of terminals can be realized by using the point-to-point communication connection. For example, taking a hundred megabyte local area network as an example, the actual transmission rate is 12M/s, which is much greater than the transmission rate of 120k/s between the server and the terminal, so that the time for the terminal to acquire the file is greatly shortened, the actual file acquisition speed is remarkably improved, and the file acquisition efficiency is improved.
209. And the first terminal generates the target file according to the first file fragment and a second file fragment acquired from at least one second terminal.
In this step, the first terminal splices the first file fragment and the second file fragment into the target file according to the position information of the first file fragment in the target file and the position information of the second file fragment in the target file. Or, the first terminal may further splice the first file fragments and the second file fragments into the target file according to the arrangement order of the first file fragments and the arrangement order of the second file fragments.
As shown in fig. 5, for a plurality of terminals establishing a peer-to-peer communication connection, each terminal shares a file fragment acquired from a server terminal with another terminal, and each terminal acquires file fragments of other terminals, thereby combining the file fragments.
As shown in fig. 6, after each terminal acquires all the file fragments, each terminal performs splicing of multiple file fragments to acquire a complete target file. In fig. 6, taking the terminal 4 as an example, the terminal 4 sequentially splices 4 file fragments according to the position information or the arrangement order of the file fragments, so as to obtain a complete target file, and of course, the terminal 1, the terminal 2, and the terminal 3 also respectively splice files according to the manner of the terminal 4.
In the embodiment of the invention, the first terminal sends the first acquisition request to the server based on the number of the target terminals and the file identification, the server firstly segments the target file, then sends the first file segment in the segmented file segments to the first terminal, and sends the second file segment in the file segments to the second terminal, and as the first file segment and the second file segment are both much smaller than the target file, the data volume actually transmitted by the server to each terminal is reduced, the transmission time is reduced, and the waiting time of a user is shortened. And the first terminal acquires the second file fragment from the second terminal through the point-to-point communication connection, and splices the first file fragment and the second file fragment into the target file.
In addition, the server does not need to send complete files to a large number of terminals one by one, actual transmission data volume of the server and network communication data volume of each terminal are reduced, and communication cost for obtaining the files is saved for users.
Fig. 7 is a schematic structural diagram of a file acquiring apparatus according to an embodiment of the present invention.
