It should be understood that, in actual applications, the mobile phone 100 may include more or less components than those shown in FIG. 3, which is not limited in the embodiment of the present application. Hereinafter, the term "when..." may be interpreted as meaning "if..." or "after" or "in response to determining..." or "in response to detecting...". Similarly, depending on the context, the phrase "when determining..." or "if detected (statement or event)" can be interpreted as meaning "if determined..." or "in response to determining..." or "when detected (Condition or event stated)" or "in response to detection of (condition or event stated)".

The following describes the application of the embodiment of the present application in the mobile phone architecture shown in FIG. 3 as an example. Refer to FIG. 4, which is a flowchart of a method for downloading a data packet provided by an embodiment of the present application. In the embodiment shown in FIG. 4, it is assumed that the first device sends the first request message to N second devices. Exemplarily, the first device and the N second devices are located in the same network. The network can be a wired network or a wireless network. The first device and the N second devices can communicate with each other, and the first device can communicate with the N second devices. The second device sends a broadcast message, and the first device may also receive feedback messages respectively sent by N second devices.

As shown in Figure 4, only the second device a and the second device b of the N second devices are drawn. The following only takes the second device a and the second device b as an example for detailed description. The specific processing of the other second devices The process can refer to the second device a and the second device b, and the repetition is not repeated here. It should be understood that the value of N is a positive integer greater than or equal to 1, for example, N=1 or N=3 or N=5, etc. This is only an example and is not a limitation of the present application.

Step 401: The first device sends a first request message to x second devices, and sends a second request message to Nx second devices, where the first request message is used to request x second devices to pass through the mobile network. The first device is assisted to download the data packet, and the second request message is used to request Nx second devices to assist the first device to download the data packet through the wireless network, x≤N, and x and N are positive integers.

In an example, the first device may request the N second devices through the first request message to assist the first device in downloading the data packet through the mobile network. As shown in Figure 5, device 1 to device n assist device A in downloading data packets from the server, where device 1 downloads the data packet fragments corresponding to device 1 from the server through the mobile bandwidth of the mobile company, and device 2 downloads the data packet fragments from the server through the mobile bandwidth of China Unicom. The data packet fragment corresponding to device 2, the device 3 downloads the data packet fragment corresponding to device 3 from the server through the mobile bandwidth of the telecommunications company, ..., the device n downloads the data packet fragment corresponding to device n from the server through the mobile bandwidth of other companies.

In an example, the first device may request x second devices through the first request message to assist the first device in downloading data packets through the mobile network, and at the same time, the first device may request Nx second devices through the wireless network through the second request message. The network assists the first device to download the data packet, where Nx<N. As shown in Figure 6, device 1 to device n assist device A in downloading data packets from the server, where device 1 downloads the data packet fragments corresponding to device 1 from the server through the mobile company's mobile bandwidth, and device 2 downloads from the server through the mobile bandwidth of China Unicom. The data packet fragment corresponding to device 2, the device 3 downloads the data packet fragment corresponding to device 3 from the server through the mobile bandwidth of the telecommunications company,..., the device n downloads the data packet fragment corresponding to device n from the server through the WiFi hotspot.

In another example, the first device may request N second devices to preferentially assist the first device in downloading data packets through the mobile network through a third request message, where the third request message is used to request the second device to preferentially assist through the mobile network. The first device downloads the data package.

It should be understood that the foregoing examples are only examples, and are not intended to limit the embodiments of the present application.

Step 402a: The second device a receives the first request message from the first device, and sends the capability information of the second device a to the first device.

It should be noted that the second device a may also receive a second request message from the first device, and send the capability information of the second device a to the first device. Alternatively, the second device a may also receive the third request message from the first device, and send the capability information of the second device a to the first device. If the second device receives the third request message from the first device, the second device a may determine whether to assist the first device in downloading the data packet through the mobile network based on its configuration or user instructions.

In the following description, only the second device a receives the first request message from the first device and sends the capability information of the second device a to the first device as an example.

In a possible design, before the second device a receives the first request message from the first device, the second device a can choose to enable the download assistance function, as shown in Figure 7(a), in Figure 7( a) The download assist function is turned on. The second device a does not enable the download assistance function, as shown in FIG. 7(b), and the download assistance function is turned off in FIG. 7(b). Then the second device a may send a response message to the first device, and the response message is used to reject the first request message of the first device, or the second device a may not send the capability information of the second device a to the first device. In another possible design, the second device a has a download assistance function by default.

In an example, after the second device a receives the first request message from the first device, the second device a may display the first information on the display screen, and the first information is used to solicit the user’s opinion whether to agree to the first request. The request message is shown in Figure 8(a). Further, the second device a may receive a user instruction. If the user instruction indicates to agree to the first request message, as shown in Figure 8(a), if the user selects "Yes", the second device a sends a second request message to the first device. Capability information of device a. If the user instruction indicates that the first request message is not agreed, as shown in Figure 8(a), if the user selects "No", the second device a sends a response message to the first device, and the response message is used to reject the first device's request. The first request message or the second device a may not send the capability information of the second device a to the first device.

In an example, after the second device a receives the first request message from the first device, the second device a may display the second information on the display screen, and the second information is used to solicit the user’s opinion whether to agree to all applications. The mobile network assists the first device to download the request message of the data packet, as shown in Figure 8(b). Further, the second device a may receive a user instruction. If the user instruction indicates to agree to all request messages that assist the first device in downloading data packets through the mobile network, as shown in Figure 8(b), if the user selects "Always agree", Then the second device a sends the capability information of the second device a to the first device, and if the user instruction indicates to agree to all request messages to assist the first device in downloading data packets through the mobile network, the second device a will only receive the first device for the first time. After a request message, the second message is displayed on the display screen. When the second device a receives the first request message sent by the first device next time, the second device a no longer displays information to prompt the user to receive the first request message. If the user instruction indicates that the request message for assisting the first device to download the data packet through the mobile network is agreed this time, as shown in Figure 8(b), if the user selects "Agree (every inquiry)", the second device a will send the request to the first device a The device sends the capability information of the second device a, and when the second device a receives the first request message sent by the first device next time, the second device a again displays the second information on the display screen. If the user instruction indicates that all request messages to assist the first device in downloading data packets through the mobile network are disapproved, as shown in Figure 8(b), if the user selects "disagree", the second device a sends a response message to the first device The response message is used to reject the first request message of the first device, or the second device a may not send the capability information of the second device a to the first device.

In another example, after the second device a receives the first request message from the first device, the second device a may display third information on the display screen, and the third information is used to solicit the user’s opinion whether to agree to all The request message for assisting other devices to download data packets through the mobile network is shown in Figure 8(c). Further, the second device a may receive a user instruction. If the user instruction indicates to agree to all requests to assist other devices in downloading data packets through the mobile network, as shown in Figure 8(c), if the user selects "always agree", then The second device a sends the capability information of the second device a to the first device, and if the user instruction indicates to agree to all requests to assist other devices in downloading data packets through the mobile network, the second device a will only receive the first request for the first time After the message, the third message is displayed on the display screen. When the second device a next receives the first request message sent by other devices (including the first device), the second device a no longer displays information to prompt the user to receive the first request message. If the user instruction indicates that the request message for assisting the first device to download data packets through the mobile network is agreed to this time, as shown in Figure 8(c), if the user selects "agree (every inquiry)", the second device a will send a request to the first device a The device sends the capability information of the second device a, and next time the second device a receives the first request message sent by the first device, the second device a again displays the third information on the display screen. If the user instruction indicates that all request messages to assist other devices in downloading data packets through the mobile network are not approved, as shown in Figure 8(c), if the user selects "disagree", the second device a sends a response message to the first device. The response message is used to reject the first request message of the first device, or the second device a may not send the capability information of the second device a to the first device.

In a possible design, the capability information of the second device a indicates the idle resources and capabilities of the second device a. The capability information of the second device a includes at least remaining storage space and network bandwidth. Wherein, the larger the remaining storage space of the second device a is, the larger the data packet fragments can be assisted to be downloaded by the first device. The larger the network bandwidth of the second device a is, the faster the first device can be assisted in downloading the data packet fragments. Optionally, the capability information of the second device a may also include computing capability (that is, CPU processing capability), stored I/O speed, and the like. It should be understood that this is only an example, and the capability information of the second device a may also include other capability parameters, and the foregoing content is not a limitation of this application.

Step 402b: The second device b receives the first request message from the first device, and sends the capability information of the second device b to the first device.

The specific processing procedure of the second device b is similar to the specific processing procedure of the above-mentioned second device a. For details, please refer to the content in step 402a, and the repetition will not be repeated.

Step 403: The first device determines a fragmentation strategy based on the N pieces of capability information, the fragmentation strategy indicates the M data packet fragments in the data packet, and the M data packet fragments and the N second devices There are M second devices in one-to-one correspondence, M is a positive integer, and M≤N.

In a possible design, after the first device receives N pieces of capability information from the N second devices, the first device determines the M pieces of capability information based on the N pieces of capability information. Two devices, the network bandwidth in each capability information in the capability information respectively corresponding to the M second devices is greater than or equal to the preset minimum network bandwidth threshold, and/or the remaining storage space is greater than or equal to the preset minimum storage space threshold.

Exemplarily, if N=2, after the first device receives the capability information of the second device a and the capability information of the second device b, the first device determines whether the second device a is capable of assisting the first device in downloading data packets , And determine whether the second device b is capable of assisting the first device to download the data package. In combination with the foregoing step 402a, it can be known that the first device can determine whether the second device a is capable of assisting the first device in downloading data packets based on the network bandwidth of the second device a. For example, if the current network bandwidth of the second device a is small, such as less than the preset minimum network bandwidth threshold, the speed of downloading data packet fragments by the second device a will be relatively slow, and the first device can give up requesting the assistance of the second device a Download the data package. The first device may determine whether the second device a is capable of assisting the first device to download the data package based on the remaining storage space of the second device a. For example, if the current remaining storage space of the second device a is small, such as less than the preset minimum storage space threshold, the second device a cannot meet the storage requirements of the downloaded data packet fragments, and the first device may give up requesting the second device aAssist in downloading the data package. In a possible design, the first device may also use but not limited to the following methods to determine the M second devices:

Step 1. Normalize the parameter value of each ability parameter in the ability information according to formula (1) to obtain the normalized value of each ability parameter.

Among them, Vmax represents the maximum parameter value of the kth capability parameter in the N capability information, Va represents the minimum parameter value of the kth capability parameter in the N capability information, and Vi represents the first capability information corresponding to the i-th second device. Parameter values of k capability parameters.

Exemplarily, if N=3, the capability information of the device 1 includes that the remaining storage space is 5G and the network bandwidth is 100Mb/s. The capability information of device 2 includes the remaining storage space of 1G and the network bandwidth of 500Mb/s, and the capability information of device 3 includes the remaining storage space of 2G and the network bandwidth of 200Mb/s. If the first capability parameter is the remaining storage space, then Vmax=5G, Va=1G, Vnorm[1]=(5-1)/(5-1)=1, Vnorm[2]=(1-1)/ (5-1)=0, Vnorm[3]=(2-1)/(5-1)=0.25, the second capability parameter is network bandwidth, then Vmax=500Mb/s, Va=100Mb/s, Vnorm [1]=(100-100)/(500-100)=0, Vnorm[2]=(500-100)/(500-100)=1, Vnorm[3]=(200-100)/(500 -100)=0.25.

Step 2: Assuming that the importance of each capability parameter in the capability information is the same, calculate the comprehensive capability value of each second device based on the above calculation result and formula (2).

Among them, Vwt represents the comprehensive capability value of the i-th second device.

Exemplarily, if N=3, the capability information of the device 1 includes that the remaining storage space is 5G and the network bandwidth is 100Mb/s. The capability information of device 2 includes the remaining storage space of 1G and the network bandwidth of 500Mb/s, and the capability information of device 3 includes the remaining storage space of 2G and the network bandwidth of 100Mb/s. If the first capability parameter is the remaining storage space, then Vnorm[1]=1, Vnorm[2]=0, Vnorm[3]=0.25, and the second capability parameter is network bandwidth, then Vnorm[1]=0, Vnorm[2]=1, Vnorm[3]=0.25. Calculated according to formula (2): Vwt1=(1+0)/2=0.5, Vwt2=(0+1)/2=0.5, Vwt3=(0.25+0.25)/2=0.25. That is, the comprehensive capability value of device 1 is 0.5, the comprehensive capability value of device 2 is 0.5, and the comprehensive capability value of device 3 is 0.25.

It should be understood that the first device can also divide the importance of each capability parameter into different levels, that is, assign different weights. At this time, the first device calculates the comprehensive capability value based on the different weights of the different capability parameters, for example, assuming that the remaining The weight of storage space is 0.4, and the weight of network bandwidth is 0.6. In the above example, Vwt1=(0.4*1+0.6*0)/2=0.2, Vwt2=(0.4*0+0.6*1)/2=0.3, Vwt3=(0.4*0.25+0.6*0.25)/2=0.25, that is, the comprehensive capability value of device 1 is 0.2, the comprehensive capability value of device 2 is 0.3, and the comprehensive capability value of device 3 is 0.25.

Step 3: Determine M second devices according to the preset comprehensive ability value threshold and the comprehensive ability values corresponding to the N second devices, where the comprehensive ability value of each second device in the M second devices is greater than or equal to The comprehensive ability value threshold is preset.

Exemplarily, if N=3, the capability information of the device 1 includes that the remaining storage space is 5G and the network bandwidth is 100Mb/s. The capability information of device 2 includes the remaining storage space of 1G and the network bandwidth of 500Mb/s. The capability information of device 3 includes the remaining storage space of 2G and the network bandwidth of 100Mb/s, assuming the importance of each capability parameter in the capability information Same, the comprehensive capability value of device 1 is 0.5, the comprehensive capability value of device 2 is 0.5, and the comprehensive capability value of device 3 is 0.25. Assuming that the preset comprehensive capability value threshold is 0.2, then M=N=3, and if the preset comprehensive capability value threshold is 0.3, then M=2, and the M second devices are device 1 and device 2, respectively.

In addition, the first device may also determine the M second devices in combination with other factors. For example, if the first device determines from the historical record that the second device a assists the first device in downloading data packets 10 times, of which 7 times the download is interrupted due to the failure or abnormality of the second device a, the first device can abandon the request The second device a assists in downloading the data package.

In a possible design, after the first device receives the N capability information from the N second devices, the first device displays M capability information on the display screen; the M capability information is the first device Filtered from N pieces of capability information based on preset rules; the first device receives a user instruction, and the user instruction indicates M second devices that agree to the first device's selection, M second devices, and M capability information One-to-one correspondence. Exemplarily, the first device may determine M second devices based on the method shown in steps 1 to 3 above, and display the capability information corresponding to the M second devices on the display screen, that is, the first device recommends the user For the optimal second device combination, the user can choose to agree with the second device combination recommended by the first device or disagree with the second device combination recommended by the first device.

In a possible design, the first device may also display capability information of N second devices on the display screen. For example, if N=2, the first device may also display the capability information of the second device a and the capability information of the second device b in a list form on the display screen. Further, the first device may receive a user instruction, the user instruction instructing M second devices among the N second devices. For example, the second device a is selected but the second device b is not selected. As shown in FIG. 9, the first device displays the capability information of device 1, device 2, and device 3 through the display screen, and the user selects device 1 and device 2 from them.

Further, after the first device determines the M second devices, the fragmentation strategy is determined based on the capability information of the M second devices, wherein the M data packet fragments meet the following conditions:

Max(s ₁ /B ₁ ,s ₂ /B ₂ ,…,s _M /B _M )+S/B'＜S/B;

s ₁ +s ₂ +…+s _M =S,s _i ≤S _i ;

Among them, s ₁ , s ₂ , ..., s _M represent the M data packet fragments, S ₁ , S ₂ , ..., S _M represent the maximum remaining storage space corresponding to the M second devices, respectively, and B ₁ , B ₂ , ..., B _M represents the network bandwidth corresponding to the M second devices, S represents the size of the data packet, B represents the network bandwidth of the first device, and B'represents the M The average value of the transmission speed at which each second device transmits corresponding data packet fragments to the first device.

It should be understood that, according to the above two constraint conditions, the optimal si value can be obtained iteratively. In the above fragmentation strategy, the first device does not participate in the download of the data packet. After the first device determines the size of the M data packet fragments, the first device needs to further determine the start position (and/or end position) of each data packet fragment.

It is understandable that the first device can also participate in downloading data packets. Assuming that the size of the data packet fragment downloaded by the first device is s ₀ , the above condition is replaced with:

Max(s ₁ /B ₁ ,s ₂ /B ₂ ,…,s _M /B _M )+(Ss ₀ )/B'＜(Ss ₀ )/B;

s ₁ +s ₂ +…+s _M ＝(Ss ₀ ), s _i ≤S _i ;

It should be understood that the foregoing method of generating a fragmentation strategy by the first device is only an example and is not a limitation of this application. The first device may also determine the fragmentation strategy based on other methods.

Step 404: The first device respectively sends corresponding fragment download requests to the M second devices based on the fragmentation strategy. Wherein, the fragment download request corresponding to the i-th second device indicates the data packet fragment corresponding to the i-th second device, i is a positive integer, and i≤M.

Exemplarily, the first device sends a fragment download request to the second device a, and the fragment download request indicates the data packet fragment corresponding to the second device. For example, the fragment download request includes the size and starting position of the data packet fragment (And/or end position).

Step 405a: The second device a receives the fragment download request corresponding to the second device a from the first device, and downloads the fragment corresponding to the second device a from the server through the mobile network based on the fragment download request corresponding to the second device a The data packet fragment corresponding to the second device a indicated by the download request.

It should be noted that if the second device a receives the second request message from the first device, then the second device a downloads the data corresponding to the second device a from the server via the wireless network based on the fragment download request corresponding to the second device a. The data packet fragment corresponding to the second device a indicated by the fragment download request. Alternatively, if the second device a receives the third request message from the first device, the second device a can determine whether to assist the first device in downloading the data packet through the mobile network based on its own configuration or user instructions, and if so, the second device a downloads the data packet fragments corresponding to the second device a indicated by the second device a from the server via the mobile network based on the fragment download request corresponding to the second device a, otherwise, the second device a is based on the second device a The segment download request corresponding to the device a downloads the data packet segment corresponding to the second device a indicated by the segment download request corresponding to the second device a from the server through the wireless network.

In a possible design, the second device a may send a first notification message to the first device every preset period of time, and the first notification message is used to notify the first device of the size of the data packet segment currently downloaded. In addition, It may also include the average download speed, and/or the length of time to wait to complete the download, etc. For example, the preset duration may be 1 minute, and the second device a sends a first notification message to the first device every 1 minute, and the first notification message is used to notify the first device of the size of the data packet fragment currently downloaded.

In another possible design, the second device a may send a first notification message to the first device every time a preset proportion of data packet fragments to be downloaded is completed, and the first notification message is used to notify the first device. The size of the data packet fragments currently downloaded by a device may also include the average download speed, and/or the waiting time to complete the download, etc. For example, the preset ratio may be 20%, and when the second device a downloads 20% of the data packet fragments that need to be downloaded, the first notification message is sent to the first device, and the first notification message indicates that the second device a has 20% of the data packet fragments that need to be downloaded when the download is complete; when the second device a completes the download of 40% of the data packet fragments that need to be downloaded, the first notification message is sent to the first device, and the first notification message indicates the second device a has downloaded 40% of the data packet fragments that need to be downloaded; when the second device a has downloaded 60% of the data packet fragments that need to be downloaded, the first notification message is sent to the first device, and the first notification message indicates the first notification message. The second device a has downloaded 60% of the data packet fragments that need to be downloaded; when the second device a has downloaded 80% of the data packet fragments that need to be downloaded, the first notification message is sent to the first device, the first notification message Indicate that the second device a has downloaded 80% of the data packet fragments that need to be downloaded; when the second device a has downloaded 100% of the data packet fragments that need to be downloaded, the first notification message is sent to the first device, and the first device a The notification message indicates that the second device a has downloaded 100% of the data packet fragments required to be downloaded.

In addition, if the second device a encounters an abnormal situation in the process of downloading data packet fragments, such as a sudden failure of the second device a, the second device a cannot continue to assist the first device in downloading the data packet. At this time, the second device a Send a second notification message to the first device, where the second notification message is used to notify the first device that the second device a cannot continue to assist the first device in downloading the data packet. After receiving the second notification message, the first device can choose to download the data packet fragment corresponding to the second device a by itself, or select another second device to take over the download task (that is, the data packet fragment corresponding to the second device a).

Step 405b: The second device b receives the fragment download request corresponding to the second device b from the first device, and downloads the fragment corresponding to the second device b from the server through the mobile network based on the fragment download request corresponding to the second device b Download the packet fragment indicated by the request.

The specific processing process of the second device b is similar to the specific processing process of the second device a described above. For details, please refer to the content in step 404a, and the repetition will not be repeated.
