For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, when the memory area of routing device is included for the privately owned memory area of terminal B, file 1 is stored by routing device Arrive for the privately owned memory area of terminal B, or, include the storage privately owned for terminal B and terminal C in the memory area of routing device During region, file 1 is stored the memory area privately owned for terminal B and terminal C by routing device.Then send to terminal B and notify Message, in order to terminal B from the memory area privately owned for terminal B or for terminal B and the privately owned memory area of terminal C lower publish papers Part 1.

In technique scheme, will be privately owned for the designated terminal in the confession candidate terminal list in the memory area of routing device Memory area as file terminal, and then realize sending literary composition at least one of the designated terminal in candidate terminal list Part, convenient and swift, and because the privately owned memory area of designated terminal supplies the privately owned access of designated terminal, so improve file storage Safety, prevent file to be compromised.

Include the memory area shared for all terminals in candidate terminal list in the memory area of routing device simultaneously And during for the privately owned memory area of the designated terminal in candidate terminal list, routing device can be according to each in candidate list The free memory of the quantity of individual terminal, the type of terminal and terminal, determines in the memory area of routing device for choosing eventually Hold the shared size of memory area of all terminals in list and for the privately owned memory area of the designated terminal in candidate list Size.

For selecting the big of the shared memory area of all terminals in terminal list in the memory area determining routing device After the little size with for the privately owned memory area of the designated terminal in candidate list, routing device can be determined according to predetermined policy Determine the storage location of file.

The first predetermined policy is the storage location of the quantity decision file of the target terminal according to file.If route sets The standby configured information according to file, determines that the quantity of the target terminal of file is more than predetermined threshold, then routing device can will be somebody's turn to do File stores the memory area shared for all terminals in candidate terminal list.So, it is to avoid routing device execution is many The secondary step that this document stores the memory area privately owned for the designated terminal in candidate terminal list, has saved routing device Power consumption.Also save the shared memory space in the memory area of routing device of file.

For example, routing device receive the transmission of terminal A file 1 and characterize file 1 target terminal be terminal B, Terminal C and the configured information of terminal D, then routing device determine that the quantity of the target terminal of file 1 is 3 it is assumed that predetermined threshold is 2, then routing device determine the target terminal of file 1 quantity be more than predetermined threshold, wrap in the memory area of routing device simultaneously Include the memory area shared for all terminals in candidate terminal list, and privately owned for terminal B in candidate terminal list During the privately owned memory area of the privately owned memory area of memory area, terminal C, terminal D, routing device stores file 1 for waiting Select the memory area that all terminals in list are shared, so, terminal B, terminal C and terminal D just supply candidate from storing to respectively File 1 is downloaded in the memory area that all terminals in terminal list are shared.

Avoid the step that routing device carries out 3 repetitions：File 1 is stored the memory area privately owned for terminal B Step, the step that file 1 is stored the memory area privately owned for terminal C, file 1 is stored the storage privately owned for terminal D The step in region.It is respectively stored into for the privately owned memory area of terminal B in candidate terminal list, terminal C compared to by file 1 The privately owned memory area of privately owned memory area, terminal D, file 1 is stored and shares for all terminals in candidate terminal list Memory area can save the shared space in the memory area of routing device of file 1, the memory space of saving is file 1 institute Account for 2 times of memory space.

Second predetermined policy is the designated terminal whether target terminal according to file is contained in candidate list, determines The storage location of file.If routing device according to the configured information of file, determine the target terminal of file be not included in wait Select the designated terminal in list, then this document can be stored and share for all terminals in candidate terminal list by routing device Memory area.So, it is to avoid routing device is not all terminals in candidate terminal list in the target terminal of file, It is impossible to store during the designated terminal being not included in candidate list, improve the response speed of routing device to file.

For example, routing device receive the transmission of terminal A file 1 and characterize file 1 target terminal be terminal B, Terminal C and the configured information of terminal D, include for all terminals in candidate terminal list in the memory area of routing device simultaneously Shared memory area, and for the privately owned memory area of the privately owned memory area of terminal E in candidate terminal list, terminal F, During the privately owned memory area of terminal S, file 1 is stored the memory block shared for all terminals in candidate list by routing device Domain, so, terminal B, terminal C and terminal D just respectively from storage to for all terminals candidate terminal list share storage File 1 is downloaded in region.

The target terminal avoiding routing device in file 1 is not all terminals in candidate list, is not included in waiting yet Situation the about during designated terminal in list it is impossible to file 1 being stored is selected to occur.Improve the response speed of routing device.

The third predetermined policy be designated terminal that whether target terminal according to file is contained in candidate list and The quantity of the target terminal of file, determines the storage location of file.If routing device is according to the configured information of file, determine literary composition The designated terminal being contained in candidate list of the target terminal of part, and the quantity of the target terminal of file is less than predetermined threshold, Then this document can be stored the memory area privately owned for the designated terminal in candidate terminal list by routing device.So, just Target terminal in file downloads file from the memory area privately owned for the designated terminal candidate list, it is to avoid file File is downloaded, due to in candidate terminal list in the target terminal memory area that all terminals are shared from for candidate list The privately owned memory area of designated terminal supplies the privately owned access of designated terminal, so improve the safety of file storage, prevents file It is compromised.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, then routing device determine that the quantity of the target terminal of file 1 is 1 it is assumed that predetermined threshold is 2, then routing device is true The quantity determining the target terminal of file 1 is less than predetermined threshold, includes arranging for candidate terminal in the memory area of routing device simultaneously The memory area that all terminals in table are shared, and for the privately owned memory area of terminal B in candidate terminal list, terminal C During the privately owned memory area of privately owned memory area, terminal D, routing device stores file 1 for terminal B in candidate list Privately owned memory area, so, terminal B just downloads file from the memory area privately owned for terminal B candidate terminal list 1.

Because the memory area privately owned for terminal B in candidate terminal list supplies the privately owned access of terminal B, so improve literary composition The safety of part 1 storage, prevents file 1 to be compromised.

In the disclosure, after routing device execution of step S43, can also carry out following steps, as shown in fig. 7, Fig. 7 It is the first flow chart of the routing device deletion file according to an exemplary embodiment.

In step S441, receive the download completion message that the target terminal of described file sends, described download completes to disappear The target terminal that breath characterizes described file has completed the download to described file.

In step S451, described file is deleted from memory area corresponding with the target terminal of described file.

After routing device sends a notification message to the target terminal of file, the target terminal of this document can access In the state of the LAN that routing device provides, from the domain of target storage, download this document, download and complete backward routing device Send and download completion message, so, routing device will receive the download completion message that the target terminal of this document sends, road Know that this document is downloaded by the target terminal of this document by equipment according to downloading completion message, then can be by this document from route Delete in the target storage domain that the memory area of equipment includes, to improve the utilization rate of the memory area of routing device.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, after file 1 is stored memory area corresponding with terminal B by routing device, sends a notification message to terminal B, In order to terminal B after accessing the LAN that routing device provides, download file 1 from memory area corresponding with terminal B.? After terminal B completes the download to file 1, terminal B sends to routing device and downloads completion message, and routing device receives terminal B After the download completion message sending, file 1 is deleted from memory area corresponding with terminal B.

In the disclosure, after routing device execution of step S43, can also carry out following steps, as shown in figure 8, Fig. 8 It is the flow chart that the routing device according to an exemplary embodiment sends transmission success prompting.

In step S442, receive the download completion message that the target terminal of described file sends, described download completes to disappear The target terminal that breath characterizes described file has completed the download to described file.

In step S452, send terminal and/or the target terminal transmission transmission success prompting of described file, institute to described State transmission success prompting and carry storage address in the target terminal of described file for the described file.

The explanation to step S441 is asked for an interview in explanation to step S442, and succinct for description, here just repeats no more.

, after the target terminal knowing file completes the download to this document, routing device can be to transmission for routing device At least one of target terminal of terminal and this document sends transmission success prompting, to point out to send terminal and this document Target terminal this document be successfully transmitted to the target terminal of this document from sending terminal.In transmission success prompting also Storage address in target terminal for the portability this document, so, receives in the target terminal sending terminal and this document After the transmission success prompting that routing device sends, storage address in the target terminal of this document for this document can be known, with It is easy to user and open this document.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, after file 1 is stored memory area corresponding with terminal B by routing device, sends a notification message to terminal B, In order to terminal B after accessing the LAN that routing device provides, download file 1 from memory area corresponding with terminal B.? After router knows that terminal B completes the download to file 1, routing device sends literary composition to one of terminal A and terminal B or two Part 1 transmission success is pointed out, and transmission success prompting carries storage address in terminal B for the file 1, in order to terminal A or terminal B User opens file 1.

Routing device sends files in target terminal to one of the target terminal sending terminal and file or two Storage address, so, the user of the target terminal of file can know storage address in target terminal for the file in time, enters And timely and conveniently open file, improve Consumer's Experience.After the target device of file completes the download to this document, road This document is deleted by equipment, improve the utilization rate of the memory area of routing device, it is to avoid the memory area of routing device Waste.

In the disclosure, after routing device execution of step S43, can also carry out following steps, as shown in figure 9, Fig. 9 It is the flow chart of the routing device according to an exemplary embodiment and the purpose terminal interaction of file.

In step S443, obtain the size of the currently available memory space of target terminal of described file.

In step S453, it is less than shared by described file in the currently available memory space of the target terminal of described file During memory space, send file transmission request to the target terminal of described file.

In step S463, receive the file transmission response that the target terminal of described file sends, described file transmission should Answer and agree to receive described file or the described file of rejection for characterizing.

In step S473, when the transmission response of described file characterizes and agrees to receive described file, to described target terminal Send cleaning memory space prompting, described cleaning memory space is pointed out empty for pointing out the target terminal of described file to carry out storage Between clear up so that the free memory after the cleaning of the target terminal of described file be not less than described file shared by storage Space.

In step S483, described file transmission response characterize reject described file when, by described file from Delete in the corresponding memory area of target terminal of described file.

Free memory in view of the target terminal of file is real-time change, so routing device is to file After target terminal sends a notification message, obtain the currently available memory space of the target terminal of file, then judge file Whether the currently available memory space of target terminal is less than the memory space shared by file.

If the currently available memory space target terminal of file is detected is not less than the memory space shared by file, Show that the target terminal of file has enough memory spaces for storage file, then send the file to the target terminal of file； If the currently available memory space target terminal of file is detected is less than the memory space shared by file, to the mesh of file Mark terminal sends file transmission request, and the target terminal of demand file receives file, and receives what the target terminal of file sent File transmit response, file transmit answer list solicit articles part target terminal whether agree to receive file.

If file transmission response is to agree to receive file, routing device points out the target terminal cleaning storage of file empty Between, then whether the free memory after the cleaning of target terminal of detection file is less than the memory space shared by file, such as Free memory after the cleaning of target terminal that fruit detects file is less than the memory space shared by file, then send out file Give target terminal；If file transmission response is rejection file, delete file, send file transmission to first terminal Failure is pointed out, or sends file bust thiss prompting to the target terminal of file, or the target terminal to first terminal and file All send file unsuccessfully to point out.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, after file 1 is stored memory area corresponding with terminal B by routing device, sends a notification message to terminal B, In order to terminal B after accessing the LAN that routing device provides, download file 1 from memory area corresponding with terminal B.Examine The free memory considering terminal B is real-time change, so the currently available memory space of routing device detection terminal B is No less than the memory space shared by file 1, if the storage that the currently available memory space of terminal B is not less than shared by file 1 is empty Between, then file 1 is sent to terminal B；If the currently available memory space of terminal B is less than the memory space shared by file 1, Send file transmission request, and the file transmission response that receiving terminal B sends to terminal B, if file transmission response is to agree to Receive file 1, then send cleaning memory space prompting to terminal B, then the currently available memory space of detection terminal B is again No less than file 1, if currently available memory space terminal B is detected is not less than the memory space shared by file 1, by literary composition Part 1 is sent to terminal B.If file transmission response is rejection file 1, delete file 1, and to terminal A and terminal B One of or two send file 1 bust thiss prompting.

On the one hand, delete file in the target terminal rejection file of file, improve the memory block of routing device The utilization rate in domain, it is to avoid the waste of the memory area of routing device.On the other hand, even if the available of the target terminal of file is deposited Storage insufficient space with storage file, also can after the target terminal cleaning memory space of file, when send a file to file in time Target terminal, improve file transmission efficiency.

In the disclosure, after routing device execution of step S43, can also carry out following steps, as shown in Figure 10, figure 10 is the flow chart that the routing device according to an exemplary embodiment sends file.

In step S444, obtain the connection status of the target terminal of described file, described connection status is used for characterizing institute The target terminal stating file accesses or does not access the LAN that described routing device provides.

In step S454, the target terminal characterizing described file in described connection status does not access described routing device and carries For LAN when, keep described file be stored in memory area corresponding with the target terminal of described file.

In step S464, detect whether the connection status of the target terminal of described file changes.

In step S474, described connection status change into characterize described file target terminal access described route set During the LAN of standby offer, described file is sent to the target terminal of described file.

Target terminal in view of file can not keep because of mobility persistently accessing the LAN of routing device offer, institute With routing device after sending a notification message, obtain the connection status of the target terminal of file to the target terminal of file, such as The target terminal that fruit detects file does not access the LAN that routing device provides, then keep the file receiving to be stored in first Memory area corresponding with the target terminal of file, then detects whether the target terminal of file accesses the office of routing device offer Domain net.If target terminal file is detected accesses the LAN that routing device provides, send the file to the mesh of file Mark terminal.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, after file 1 is stored memory area corresponding with terminal B by routing device, sends a notification message to terminal B, In order to terminal B after accessing the LAN that routing device provides, download file 1 from memory area corresponding with terminal B.Examine The free memory considering terminal B is real-time change, so whether routing device detection terminal B accesses routing device and provide LAN, detect terminal B access routing device provide LAN when, file 1 is sent to terminal B.

In technique scheme, the detection function that had using routing device, you can access road in the target terminal of file The target terminal of file is provided during the LAN being provided by equipment in time, improves the efficiency of file transmission.

In the disclosure, after routing device execution of step S43, can also carry out following steps, as shown in figure 11, figure 11 is the second flow chart of the routing device deletion file according to an exemplary embodiment.

In step S445, obtain the connection status of the target terminal of described file, described connection status characterizes described literary composition The target terminal of part accesses or does not access the LAN that described routing device provides.

In step S455, the target terminal characterizing described file in described connection status does not access described routing device and carries For LAN when, keep described file be stored in memory area corresponding with the target terminal of described file.

In step S465, detect whether the connection status of described target terminal changes in scheduled duration.

In step S475, when described connection status does not change in scheduled duration, by described file from described literary composition Delete in the corresponding memory area of target terminal of part.

Explanation to step S344 and step S354 refer to above, and here just repeats no more.

With the scheme shown in Fig. 9 except that, routing device and then detect the target terminal of file whether in pre- timing The LAN that routing device provides is accessed in long.If target terminal file is detected does not access route in scheduled duration and sets The standby LAN providing, then the communication connection between the target terminal of supporting paper and routing device is bad, in order to improve route The utilization rate of the memory area of equipment, this document is deleted from the domain of target storage by routing device, and to transmission terminal and literary composition One of target terminal of part or two transmission bust thiss promptings.

For example, routing device receives the file 1 of terminal A transmission and the target terminal of sign file 1 is terminal B Configured information, after file 1 is stored memory area corresponding with terminal B by routing device, sends a notification message to terminal B, In order to terminal B after accessing the LAN that routing device provides, download file 1 from memory area corresponding with terminal B.Examine The free memory considering terminal B is real-time change, so whether routing device detection terminal B accesses routing device and provide LAN, detect terminal B do not access in scheduled duration routing device offer LAN, then delete file 1, and Send file 1 bust thiss prompting to one of terminal A and terminal B or two.

The LAN of routing device offer, in technique scheme, is not provided in scheduled duration in the target terminal of file When delete file, improve the utilization rate of the memory area of routing device, it is to avoid the waste of the memory area of routing device.

Figure 12 is the flow chart of a kind of method of transmission file according to an exemplary embodiment, as shown in figure 12, The method of transmission file is used for transmitting the transmission terminal in the system of file.The method of transmission file comprises the following steps.

In step S121, in the state of accessing the LAN that routing device provides, obtain from described routing device Candidate terminal list, described candidate terminal list includes the parameter information of default terminal, and described default terminal includes being currently accessed And/or history accesses the terminal of the LAN that described routing device provides.

From described candidate terminal list, in step S122, determine the target terminal of described file.

In step S123, the configured information of described file and the target terminal characterizing described file is sent to described Routing device.

Terminal in the disclosure, after accessing the LAN that routing device provides, can read candidate eventually from routing device End list, and obtain the information of each terminal in candidate terminal list.For example：Assume that terminal A and terminal B are respectively connected to The LAN that routing device provides, then terminal A and terminal B can obtain the information of other side.

Again for example：Terminal A, terminal B and terminal C are respectively connected to the LAN of routing device offer, and terminal C disconnects and route Connecting between the LAN that equipment provides and the LAN that access routing device does not provide again in scheduled duration, then make a reservation for After duration reaches, terminal C as the terminal of the LAN accessing routing device offer, and terminal C is listed in by routing device History terminal list, then terminal A, terminal B and terminal C can obtain information each other.

In document transmission process, terminal reads candidate terminal list first from routing device, then according to positioned at time Select the memory space shared by the free memory of terminal and file in terminal list, therefrom select at least one terminal to make For the target terminal of file, then file and configured information are sent to routing device.

For example it is assumed that the candidate terminal list that terminal A reads from routing device is：Terminal A, terminal B and end End C, the then free memory of the memory space according to shared by file 1 and terminal A, terminal B and terminal C, select terminal B As the target terminal of file 1, then, file 1 and configured information are sent to routing device.

Again for example it is assumed that the candidate terminal list that terminal A reads from routing device is：Terminal C, then basis Memory space shared by file 1 and the free memory of terminal C, select terminal C as file 1 target terminal, then, File 1 and configured information are sent to routing device.

In technique scheme, for file sender (for example：Send terminal, or terminal A) for it is desirable to file is sent out The configured information of file and file is transferred to routing device by the side of sending.Need not keep file sender and file reception side it Between real-time connection, optimize Consumer's Experience.

In the disclosure, the currently available storage including each terminal in described candidate terminal list in described parameter information is empty Between size when, step S122 may comprise steps of, and as shown in figure 13, Figure 13 illustrates according to an exemplary embodiment A kind of flow chart of step S122 that method of transmission file includes.

In step S1221, the size of memory space relatively shared by described file is each with described candidate terminal list The size of the currently available memory space of individual terminal.

In step S1222, determine the target terminal of described file, the currently available storage of the target terminal of described file Space is more than the memory space shared by described file.

Include the size of the currently available memory space of each terminal in candidate terminal list due to parameter information, so sending Terminal, can be by the size of the memory space shared by this document and each terminal in terminal list after determining file to be sent The size of currently available memory space compares, it is then determined that going out current free memory to be more than memory space shared by file Terminal, the target terminal of select file from the terminal determined.

For example, terminal A determines that file to be sent is file 1, and the memory space shared by file 1 is 500MB, terminal The list of the candidate terminal that A reads from routing device includes：Terminal B, terminal C and terminal D, the currently available storage of three Space is respectively：600MB, 300MB, 700MB.Then terminal A using one of terminal B and terminal D as file 1 target terminal, or Person is using terminal B and terminal D all as the target terminal of file 1.

Using technique scheme, each terminal in the size of the memory space according to shared by file and candidate terminal list The size of currently available memory space, determines the target terminal of file, it is to avoid the currently available storage of the target terminal of file Space is less than the memory space shared by file, so lead to the target terminal of file because there is no enough memory spaces and cannot under The situation carrying this document occurs, and improves the efficiency of file transmission.

Figure 14 is the flow chart of a kind of method of transmission file according to an exemplary embodiment, as shown in figure 14, The method of transmission file is used for transmitting the purpose terminal of the file in the system of file.The method of transmission file includes following step Suddenly.

In step S142, from the domain of described target storage, download described file.

Terminal in the disclosure can be used as the target terminal of file.The target terminal of file is accessing routing device offer LAN in the state of, the notification message of routing device can be received, know the memory block of routing device according to notification message There is Downloadable file, then, the target terminal of file downloads file from the memory area of routing device in domain.

For example it is assumed that the target terminal of file 1 is terminal B, access, in terminal B, the LAN that routing device provides Under state, receive the notification message that routing device sends, this notification message characterizes the literary composition storing in the memory area of routing device Part 1 is Downloadable, and then terminal B downloads file 1 from the memory area of routing device.

In technique scheme, for file reception side (for example：The purpose terminal of file, or terminal B) for it is desirable to The notification message that file reception root sends according to routing device, downloads file from the memory area of routing device.File Recipient need not keep the real-time connection and file sender between, without the local keeping persistently access routing device offer Net, optimizes Consumer's Experience.

In the disclosure, it is additionally operable to indicate storage position in the domain of described target storage for the described file in described notification message When putting, step S122 is：Described file is downloaded storage location indicated by from described notification message.

A kind of possible situation is：Notification message indicates that described file is stored in the memory area of described routing device and supplies The memory area that all terminals in candidate terminal list are shared, then the target terminal of file is from for the institute candidate terminal list Have in the shared memory area of terminal and download described file.

Alternatively possible situation is：Notification message indicates that described file is stored in the memory area of described routing device For the privately owned memory area of the designated terminal in candidate terminal list, then the target terminal of file is from for candidate terminal list Described file is downloaded in the privately owned memory area of designated terminal.

Wherein, the explanation to all terminals, designated terminal, the memory area of routing device, candidate terminal list refer to Above, here just repeats no more.

For example it is assumed that the target terminal of file 1 is terminal B, indicate that file 1 is stored in for candidate eventually in notification message During the memory area that in the list of end, all terminals are shared, then the terminal B storage that all terminals are shared from for candidate terminal list File 1 is downloaded in region.

For example it is assumed that the target terminal of file 1 is terminal B, indicate that file 1 is stored in for candidate eventually in notification message In the list of end during the privately owned memory area of terminal B, then in terminal B privately owned memory area of terminal B from for candidate terminal list Download file 1.

Again for example it is assumed that the target terminal of file 1 is terminal B, indicate that file 1 is stored in notification message and supply candidate Terminal B and during the privately owned memory area of terminal C in terminal list, then terminal B terminal B and terminal C from for candidate terminal list File 1 is downloaded in privately owned memory area.

In technique scheme, on the one hand, will be all in the confession candidate terminal list in the memory area of routing device The memory area that terminal is shared is as file terminal, and then realizes file group sending, convenient and swift；On the other hand, route is set In confession candidate terminal list in standby memory area, the privately owned memory area of designated terminal is as file terminal, and then realizes To at least one of designated terminal transmission file, convenient and swift, and because the privately owned memory area of designated terminal is for specifying eventually Holding privately owned access, so improve the safety of file storage, preventing file to be compromised.
