Embodiment
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
The alleged multi-module mobile terminal of the present invention is meant the portable terminal of the communication network that is applicable to different systems; The communication network of single standard is called the single-mode network that this multi-module mobile terminal is supported, the standard of the communication network that multi-module mobile terminal then of the present invention can be supported can be: the combination in any of PHS, GSM, EDGE, CDMA2000, WCDMA, TD-SCDMA, WIMAX and WIFI etc.
The resource downloading method that the present invention is based on multi-module mobile terminal is as shown in Figure 1, comprising:
Concrete realization will be explained through embodiment shown in Figure 2, being comprised:
At first; Multi-module mobile terminal need confirm which the network formats of self supporting has; And the standard downlink transmission data rate that the communication network of confirming this standard is supported in theory is what, and these parameters pre-set generally speaking, for multi-module mobile terminal be give tacit consent to known.The present invention supports that with multi-module mobile terminal the communication network (being mode mobile terminal) of two kinds of standards is an example.
When being GSM network and TD-SCDMA network like the single-mode network of mode mobile terminal support; The standard downlink transmission data rate of GSM network is 9.6kbps; The standard downlink transmission data rate of TD-SCDMA network is 384kbps, and the message transmission rate that can know the TD-SCDMA network is greater than the GSM network.
Mode mobile terminal inserts two single-mode network (network A, network B) simultaneously, and foundation is connected with the data service physical of network A and network B respectively, and obtaining network A simultaneously is that its IP address allocated A and network B are its IP address allocated B.Concrete; The mode of this connection of mobile terminal into network A and network B is according to the standard of network A and network B and different; The portable terminal mode that can dial through a kind of Modem commands language AT order when to insert standard be the network of GSM or EDGE for example can be called point-to-point protocol formula (PPPD, the Point to Point Protocol daemon) program of self operating system after the dial-up success; Utilize point-to-point (P2P; Point to point) agreement is come access network, insert successfully after, network is portable terminal distributing IP address.Concrete network is the prior art that is embodied as of portable terminal distributing IP address, repeats no more here.
Portable terminal can pass through HTTP (HTTP; Hypertext Transfer Protocol) the Range parameter of protocol header is to the download request of Resource Server transmitting section resource, and judges the breakpoint transmission of whether supporting current resource through the answer message of Resource Server.Need to prove that portable terminal can send to the resource downloading server through any single-mode network of its support should request.
Being that to download test.zip by name, size be that the resource of 5MB is an example for the resource downloading server of www.abc.com from domain name; Suppose that portable terminal need begin from the appointment breakpoint location of this resource to download, download as beginning from 1MB; Then portable terminal can send to the resource downloading server through the Range parameter of http header and download the 1MB request of resource afterwards, and the particular content of this request is following:
GET/test.zip?HTTP/1.0
RANGE：bytes＝1024000-
Accept：text/html，image/gif，image/jpeg，*；q＝.2，*/*；q＝.2
Wherein, GET/test.zip has indicated the title of this resource; " RANGE:bytes=1024000-" explains the resource after the mobile terminal request file in download 1MB.
Information through the resource downloading server returns judges whether the resource downloading server supports the breakpoint transmission to current resource, if do not support breakpoint transmission, then returns following information:
200
Content-Length＝5070000
Accept-Ranges＝bytes
Date＝Thu，2Apr?2009?12:56:11GMT
ETag＝W/”02ca57e173c11:95b”
Content-Type＝application/octet-stream
Server＝Microsoft-IIS/5.0
Last-Modified＝Thu，2Apr?2009?12:56:11?GMT
If support breakpoint transmission, then return following information:
206
Content-Length＝5070000
Content-Range＝bytes?1024000-5070000/5070000
Date＝Thu，2Apr?2009?12:55:20GMT
ETag＝W/”02ca57e173c11:95b”
Content-Type＝application/octet-stream
Server＝Microsoft-IIS/5.0
Last-Modified＝Thu，2Apr?2009?12:55:20GMT
With supporting the corresponding information information corresponding of breakpoint transmission to compare and can find, support the corresponding information of breakpoint transmission to increase delegation with not supporting breakpoint transmission:
Content-Range=bytes 1024000-5070000/5070000, because the size of this document is 5MB, so this statement expresses support for the download from 1MB to the 5MB data; In addition, the code that returns also becomes 206 by 200, resource downloading server support breakpoint transmission function can be described at these 2.
If the resource downloading server is not supported the breakpoint transmission to current resource; Explain that then the resource downloading server do not support the mode that this resource is downloaded each data segment simultaneously with multithreading is downloaded; This moment, execution in step 3 was selected the maximum single-mode network (message transmission rate of supposing network A is then selected network A greater than network B) of message transmission rate; Carry out the download of resource: portable terminal A Network Based distributes to its own IP address A; Establishment is connected (this is connected to single-threaded connection, is used for the download of resource) with the socket of network A, portable terminal sends the request of downloading the complete resource of this document through network A to the resource downloading server then; The resource downloading server is connected to portable terminal with the socket of portable terminal through network A and returns resource, accomplishes up to this resource downloading, and this flow process finishes.
The request (the resource test.zip by name that request is downloaded) of the complete resource of download that portable terminal sends to the resource downloading server is as follows:
GET/test.zip?HTTP/1.1
Accept：image/gif，image/x-xbitmap，image/jpeg，image/pjpeg，
Application/vnd.ms-
excel，application/msword，application/vnd.ms-powerpoint，*/*
Accept-Language：zh-cn
Accept-Encoding：gzip，deflate
Connection：Keep-Alive
If the resource downloading server is supported the breakpoint transmission to this resource, explain that then the mode that can adopt multithreading to download each data segment simultaneously for this resource downloads this resource, this moment execution in step 4.
Usually; In order the resource downloading service to be provided for more user; The resource downloading server can be connected with a restricted number to the download that same IP address (be the IP address of a corresponding single-mode network of multi-module mobile terminal among the present invention, like IP address A or IP address B) request is set up, and (each bar is downloaded and is connected corresponding download thread; Then confirmed maximum download thread numbers here), and download the message transmission rate that connects to every and limit.Only allow a portable terminal can create 5 at most like the resource downloading server and download connection, correspond to 5 download thread, be that maximum download thread numbers are 5, download the message transmission rate that connects for every and be restricted to 10kbps based on an IP address; Do not considering under the prerequisite of current network standard to the transfer of data rate limit that then the speed that portable terminal at most can 5 * 10kbps is carried out the download of resource.In addition; Consider the hardware resource configuration of portable terminal and the efficient of resource downloading; Can not with download thread open too much; Can bring very big overhead like this, so the maximum download thread that multi-module mobile terminal self need be defined under the single-mode network counts MAXTHREADS, MAXTHREADS confirms as an empirical value.In the application of reality; The maximum download thread under single-mode network that multi-module mobile terminal can be created counts MAX and MAXTHREADS possibly be inconsistent; Therefore, multi-module mobile terminal at first need go to decide the value of MAX, in the process of confirming MAX, creates MAX bar download thread.
Concrete, confirm that the maximum download thread under the single-mode network is counted MAX, and the establishment of MAX bar download thread can be adopted flow process shown in Figure 3:
Step 302 is created a socket based on the single-mode network IP address allocated and is connected (being download thread), to be connected to the resource downloading server;
Step 303 judges whether connection is successful, if not, and execution in step 304; If, execution in step 305.
If successful connection representes that this socket connects (being download thread) and creates successfully.
Step 304 judges that current download thread counts I and be MAX, and this flow process finishes.
Step 305 judges that current download thread counts I and whether count MAXTHREADS less than the maximum download thread under this single-mode network of portable terminal self regulation, if not, execution in step 304 explains that current download thread counts I and be MAX, and this flow process finishes; If, execution in step 306;
This shows that multi-module mobile terminal has also been accomplished the establishment of MAX bar download thread in definite MAX bar download thread.Generally speaking, the MAX value under each single-mode network is identical.
Can learn the partial data of whether downloading this resource according to portable terminal to the storage condition of current resource, if not, execution in step 6; If, execution in step 7.
Portable terminal need be downloaded complete resource, at first need distribute the data segment of each download thread request according to the standard downlink transmission data rate that the size of this resource, maximum download thread under each single-mode network are counted under MAX and each single-mode network.Concrete, can adopt following allocation strategy:
If requested resource size (being complete resource in this step) is S, this portable terminal is mode mobile terminal network enabled A and network B, and the standard downlink transmission data rate under the network A is V
A, the standard downlink transmission data rate under the network B is V
B, establish V
A/ V
B=P.
Then can the requested resource size be through network A: S * [P/ (P+1)], every download thread can the requested resource size be under the network A: { S * [P/ (P+1)] }/MAX;
Then through network B can the requested resource size be: S/ (P+1), every download thread can the requested resource size be under the network B: [S/ (P+1)]/MAX.
For example, the standard of network A is GSM, standard downlink transmission data rate V
A=9.6kbps; The standard of network B is TD-SCDMA, standard downlink transmission data rate V
B=384kbps; Amounting to request resource size S is 5MB; MAX is 5, then: P=9.6/384=0.025.
Through network A can the requested resource size be: 5* [0.025/ (0.025+1)] MB=0.12MB, every download thread can the requested resource size be under the network A: 0.12/5MB=0.024MB;
Through network B can the requested resource size be: 5/ (0.025+1) MB=4.88MB, every download thread can the requested resource size be under the network B: 4.88/5MB=0.976MB.
The data segment that can calculate every thread request according to every download thread requested resource size (uses starting point to represent, is 0MB～0.024MB) like the data segment of a certain download thread request; Portable terminal is created the download request of the part resource of corresponding every download thread then, and through each download thread request is sent to the resource downloading server.Can adopt the download request form of describing in the step 2 to the part resource to the download request of part resource, the title of concrete resource, size information such as (starting points) are according to actual conditions and difference.
The concrete realization of this step is identical with step 6, repeats no more here.Different is, step 6 request be complete resource, current resource has been downloaded a part in this step, so S representes the not size of downloaded resources in this step.
The resource that step 8, each download thread receive with the blocks of files mode and the storage resources Download Server returns.
Resource Server returns corresponding resource through mobile communications network to each download thread when the download request of the part resource that receives each download thread transmission; Each download thread receives and preserves the resource that the resource downloading server returns with the blocks of files mode.
Step 9 when a download thread downloaded resources under certain single-mode network is accomplished, judges whether all download thread under this single-mode network accomplish resource downloading, if, execution in step 10; If, do not return step 8.
When a download thread of a single-mode network is accomplished resource downloading, judge whether all the MAX bar download thread under this single-mode network accomplish resource downloading; If, execution in step 10; If not, then continue execution in step 8, continue to download and do not accomplish the resource of downloading.
If all download thread under all single-mode network have all been accomplished resource downloading, then whole resource downloading of this mobile terminal request finish, and this flow process finishes; Otherwise, execution in step 12.
Need to judge whether the download connection (being download thread) of the uncompleted single-mode network of resource downloading is effective this moment, if effectively, then can continue the download of resource, execution in step 8; If invalid, explain to exist signal quality problem or other to influence the problem of resource downloading under this single-mode network that the download that can discharge this single-mode network this moment connects execution in step 13.
When the download thread of single-mode network is invalid in the step 12, discharge the download thread (the corresponding download connects) of this single-mode network, stop resource downloading; Confirm the resource size that this single-mode network downloaded (after might this single-mode network having downloaded a part of resource, owing to reasons such as signal quality make download connect invalid), and according to the resource of not downloading; Establishment is carried out the download of resource, with step 7 based on the download thread of downloading the single-mode network of accomplishing; Repeat no more here; Return execution in step 8 then, finish up to resource downloading, this flow process finishes.
In order to realize said method, the present invention also provides a kind of resource downloading system, and this system is applicable to multi-module mobile terminal, and is as shown in Figure 4, comprising:
Accordingly; Shown in resource downloading module 40 be further used for, according to the result of judge module 30, judging when invalid; The download thread of the single-mode network of downloading is accomplished in release, and the resource through not downloading in the invalid single-mode network of the single-mode network request download thread of download completion.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
