This invention discloses a system including: a CP, MS and terminals, in which, a terminal is connected with the CP, MS and other terminals connected with it when downloading shared data to realize multipoint downloading.
Description
Technical field
The present invention relates to data sharing technology, be meant the method and system of terminal download of sharing data under a kind of point-to-point (P2P, Peer to Peer) mode especially.
Background technology
The mode of shared data can be by sharing in the local area network (LAN) on the network, and the file transfer on the Internet (Internet) realizes, the mode of these shared data all needs terminal to know reciprocity terminal and by realizing data sharing after the authentication of reciprocity terminal, has limited the scope of sharing greatly.Like this, occurred many P2P file-sharing patterns at present, made terminal as long as the required content of search just can access shared file.
Along with mobile network's continuous development, some functions that computer can be realized are progressively to the portable terminal transition.P2P is in the application of aspects such as instant messaging, data sharing, file search, for making full use of of Internet resources provides a good platform instrument.P2P updates, and has alleviated load of server, and server only needs the front end tissue as a communication, for terminal provides a demand information searching platform, and ensures connectivity end to end.
At present, under the P2P mode, the process of terminal downloads relation data is roughly as follows: terminal is inquired about Downloadable shared data to management server (MS), the Downloadable shared data that returns according to MS then, select a content provider (CP) that shared data is provided, and connect with it, the shared data that this CP is provided is downloaded to the local terminal.Download the whole process of finishing from being connected to shared data, terminal only can go up download of sharing data from CP, and terminal can only connect with a CP.CP can connect with a plurality of terminals simultaneously.Finishing the terminal that shared data downloads can register and issue, and become a CP by to the MS application, and like this, identical shared data just can be provided by different suppliers, is the terminal that the needs download of sharing data space that provides more choices.The user of terminal can select with which CP to connect by the performance and the price that compare each CP, and like this, the quantity of CP is just in continuous increase, and terminal selectable chance when download of sharing data is also just many more.
The download technology that great majority are applied among the mobile network all is that above-mentioned single-point is downloaded, and single-point is downloaded to the management of operator has alleviated burden, has effectively prevented the illegal propagation of content.According to the demand of terminal, can find the CP that shared data is provided very clearly, highly beneficial for the protection copyright.But, if a plurality of terminal connects with download of sharing data with a CP simultaneously, just formed the pattern of central server, because the resource-constrained of CP will make speed of download descend, even cause the congested of network.
CP provides shared data for terminal, and dominating the downloading process of whole shared data, if CP interrupts suddenly, the terminal that connects with this CP will all can't be finished the download of shared data so, and the result who finally causes is to be the whole download system paralysis at center with CP.At this moment, several situations of having no progeny in must considering to download, for example, continue again to download after terminal wait CP recovers normally, or terminal is reselected a new CP, if terminal is reselected a new CP, so, after terminal and this CP connect, be that interruptions begins to download during from the last downloaded shared data, still restart to download, these processes such as all can relate between terminal, each CP at the conflict of interest of each side.
In addition, MS is according to the inquiry of terminal, for the Downloadable shared data of terminal searching and when offering terminal, the Downloadable shared data that search mechanisms requires MS to search is The more the better, makes terminal can obtain more the information about Downloadable shared data.But, for a terminal, wish that the Query Result that MS returns is short and sweet, the shared data content that provides all can realize, do not wish that MS returns the Query Result of the shared data content that has repetition, or return some restrictions owing to the hardware environment of terminal, and even download, the shared data that terminal also can't be used.
In addition, terminal is downloaded the whole process of finishing the variation of connection status between MS less relevance terminal, CP and terminal and the CP from establishing a connection to CP.Terminal can be selected to interrupt at any time, also can continue a little shared data in follow-up any time and download, and like this, terminal can be grasped download time neatly, need not the participation of MS, makes that the management of MS is also simpler.Though MS need not to close the connection status between injection terminal and the CP in the downloading process of shared data, but after interrupting taking place, owing to the reason of chargeing, but need MS arbitrate interrupting, determining to interrupt is to be initiated or initiated by terminal by CP, terminal is deducted fees determining whether, at this moment, because MS does not close the connection status between injection terminal and the CP, make that MS is difficult to determine to interrupt by which side being initiated, cause the conflict on each side's interests; And, because MS does not pay close attention to the state of CP, make MS in the Query Result that terminal is returned, comprise disabled CP probably, for example, be in the CP of interrupt status or not online CP.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Among the present invention, when terminal and CP connect download of sharing data, not only can be from coupled CP download of sharing data, also can connect by the other-end that links to each other with this CP, and from the corresponding terminal download of sharing data, make the load of CP reduce greatly; And the other-end quantity that links to each other with CP is many more, and the chance of this terminal while download of sharing data is just many more, can improve the speed of download.
In addition, the Adapted information collecting unit is set in terminal among the present invention, adaptive filter element is set in MS, like this, Adapted information collecting unit in the terminal is gathered terminal ability information, when terminal needs download of sharing data, when request MS provides Downloadable shared data, provide the terminal ability information of self to MS; After MS searches for Downloadable shared data according to the request of terminal, the terminal ability information that adaptive filter element among the MS provides according to terminal, Search Results is filtered, to filter out with the incompatible Search Results of terminal capability, only keep the Search Results that adapts with terminal capability, return the Search Results of reservation then to terminal, make Query Result that MS returns to terminal simple and clear more, and have the high characteristics of In-commission Rate.
P2P digital content shared platform among the present invention provides the platform of download of sharing data for terminal, and has made full use of the terminal resource in the network.In whole shared data downloading process, relate to three entity: MS, CP and terminal, realize data sharing, download and distribution of interests between this three.CP described in the present invention can be author, carries out favourable protection with the originality to digital content.
Realize the download of terminal to shared data, CP at first needs digital content is registered as shared data in MS, and specifically processing procedure is as shown in Figure 1:
Step 101～step 102:CP creates digital content, digital content is registered as in MS before the shared data, digital content is got the nod, can pass through certification authority, as copyright publisher (RI), digital content is carried out copyright or original authentication, digital content is carried out digital copyright management (DRM) registration.
After step 103～step 104:CP successfully carries out the DRM registration to digital content, with digital content packing and piecemeal, piecemeal is meant the digital content after the packing is divided into a plurality of data blocks, for example, the digital content of one 710 kilobytes (KByte), CP can logically be divided into it data block of 11 64KByte sizes, and last data block is the 6KByte size, can distinguish different data blocks by block identification.In addition, CP also can be divided into digital content a plurality of data blocks that differ in size.
Step 105～step 106:CP sends the essential information of digital content to MS, divide block message etc. as copyright information, CP information, content indexing information, content size, content essential information, content, the content essential information can comprise the author of digital content, the basic introduction of digital content, the price of opening form, digital content of digital content etc.After MS receives the essential information of digital content, for digital content is set up index, attribute according to digital content generates content adaptation information, this content adaptation information is for using the terminal capability of respective digital content, promptly terminal normally use digital content the ability information that must possess, and be that this digital content generates stored information, the digital content of this CP of terminal downloads, when being shared data, MS can increase each end message that links to each other with CP and the download performance of each terminal on the basis of this stored information.After CP was sent to MS with the essential information of digital content, the branch block message of digital content had just no longer changed.
Step 107:MS has judged whether to subscribe to the state of CP, if, then notify CP successfully digital content to be registered as shared data, execution in step 109 then; Otherwise, execution in step 108.The essential information of the above digital content is the essential information of shared data.The state that MS subscribes to CP is meant that MS can know whether the CP current state is presence.
Step 108:MS is that CP orders existence.And notify CP successfully digital content to be registered as shared data, execution in step 109 then.MS can realize that service (IMPS) is CP order existence by instant messaging.
Step 109:CP waits for terminal download of sharing data.
CP just can supply terminal downloads after successfully being registered in shared data on the MS.Fig. 2 shows terminal download of sharing data flow chart among the present invention, and as shown in Figure 2, the implementation procedure of terminal download of sharing data may further comprise the steps:
Step 201: when terminal needs download of sharing data, send query requests, carry Query Information in this query requests to MS, this Query Information can be the keyword of shared data, also can be the file name of shared data, also can be the relevant information of shared data, as author information; Can further carry terminal ability information in this query requests, require MS to return Query Result according to terminal capability, this terminal ability information can be gathered by the Adapted information collecting unit that is arranged at terminal.
After step 202:MS received the query requests of terminal transmission, search met the Query Result of Query Information.Owing to store among the MS and the required corresponding content adaptation information of ability information of terminal that can use shared data, therefore, if carry terminal ability information in the query requests, then according to the content adaptation information of terminal ability information and storage, Query Result is carried out the suitability filtration treatment, to filter out with the incompatible Query Result of terminal ability information, keep the Query Result that adapts with terminal ability information, then the Query Result after terminal is returned filtration.If carried terminal ability information not in the query requests, then MS directly returns the Query Result that searches to terminal.At the few characteristics of portable terminal displaying contents, MS can be to the Query Result optimization of classifying, so that provide better demonstration to check effect to the user.The Search Results that MS returns to terminal can comprise: the price of CP information, shared data title, shared data size, shared data brief introduction, shared data etc., and, this Search Results can further comprise: each end message that links to each other with CP, the download performance of each terminal, or the like.
Step 203～step 204: terminal receives the Query Result that MS returns, and selects the CP that shared data can be provided according to this Query Result then, and connects in this CP.Terminal is in the process that CP is connected, MS judges at first whether terminal has enough account balances, if remaining sum abundance, just allow terminal and CP to connect, carry out the download of shared data, if Sorry, your ticket has not enough value, then do not allow terminal and CP to connect, the refusal terminal is to the download of shared data.After terminal and CP successfully connect, can check the branch block message of shared data, size as shared data, the size of each data block, if CP is divided into equal-sized data block with the digital content of shared data, then terminal can be according to the size of shared data and the size of a data block, calculate the quantity of the data block that shared data comprises, for example, the shared data of a 200KByte, terminal knows that CP logically is divided into each data block 32KByte size with this shared data, then terminal can calculate the data block that this shared data comprises 6 32KByte sizes, and last data block is the 8KByte size.
Step 205～step 206: the other-end that terminal links to each other with CP to the MS inquiry, this CP are the CP that connects with terminal.MS returns the other-end information that links to each other with corresponding CP to terminal, and some terminals in that terminal can be selected to link to each other with CP, the other-end connect, and also can select to connect with other-end that corresponding CP links to each other with all.
Step 207: terminal has been finished the data downloaded piece to coupled other-end inquiry, makes and realizes having finished in the shared data sharing of downloaded contents between each terminal.
Because in the shared data downloading process, relate to a large amount of dynamic datas, increase and minimizing as the terminal quantity that links to each other with CP, the variation of each SOT state of termination that links to each other with CP etc., therefore, dynamic memory some information among the MS, as shown in Figure 3A, canned data comprises call number among the MS, CP information, shared data essential information and download list etc., wherein, the shared data essential information comprises copyright information, content indexing information, content size, the content essential information, content is divided block message and content adaptation information, and download list can be the terminal essential information, and the terminal that includes essential information in the download list is the current terminal that links to each other with CP.The pricing information that can comprise shared data title, shared data brief introduction, shared data in the content essential information, or the like.Content piecemeal information comprises the sign and the size of shared data size, each data block.Content adaptation information be for using the required ability information of terminal of corresponding shared data, promptly terminal normally use shared data the ability information that must possess.Like this, owing to the relevant information of storing among the MS in the various downloading process, terminal just can be obtained the information of the other-end that links to each other with CP by MS, selects to connect with some terminals, and can further obtain connecting terminal and finish the data downloaded block message.
Step 208: the other-end that terminal is returned according to MS and finish corresponding relation between the data downloaded piece judges whether the data block that needs, if then execution in step 209; Otherwise, execution in step 210.The above data block that needs is that terminal is determined the current data downloaded piece that needs, and terminal can be determined the current data downloaded piece that needs at random, also can determine the current data downloaded piece that needs according to the priority of each data block in shared data.
Step 209: terminal is downloaded the desired data piece from coupled corresponding terminal, and corresponding terminal is for finishing the terminal that respective data blocks is downloaded, and execution in step 211 then.
Step 210: terminal is downloaded the desired data piece from CP, and execution in step 211 then.
By step 208～step 210 make terminal can from other with terminal that CP links to each other on the data block of download of sharing data, alleviated the burden of CP; And the other-end that links to each other with CP is many more, and the chance of the data block of terminal download of sharing data is just many more, may promote speed of download.
Step 211: whether terminal judges needs the data downloaded piece in addition, if then return execution in step 207; Otherwise, execution in step 212.
In the downloading process of whole shared data, because accident may make a certain side go offline, cause the download of shared data to finish, because the download platform of shared data is a transaction platform to a certain extent, this emergentness goes offline, can bring loss for the opposing party, for example, CP goes offline suddenly, will cause and the be connected disconnection of terminal with this CP, at this moment, the interruption of download of sharing data is caused by CP, if coupled terminal is chargeed before continuing CP gone offline, then make each terminal for not finishing the shared data payment extra-pay of download, for the user of terminal brings unnecessary loss; Terminal goes offline suddenly, though make the shared data of this terminal download and can't finish,, if initiatively disconnecting the terminal that causes with being connected of CP, terminal goes offline suddenly, because this terminal has been downloaded the part shared data, if this terminal is not chargeed, then can bring loss for CP.Like this, for reasonable, fair ruling, introduce interrupt processing mechanism among the MS.In the shared data downloading process of step 207～step 211, when MS carries out Interrupt Process at needs, determine the triggering side of interruption, and carry out Interrupt Process according to the triggering side of the interruption of determining.MS determines that the situation need carry out Interrupt Process comprises: MS receives interrupt requests, or the current state that MS detects CP or terminal is an off-line state.Terminal or CP all can send interrupt requests to MS according to actual conditions, after MS receives interrupt requests, determine to carry out Interrupt Process, and the transmit leg of interrupt requests is defined as the triggering side of interrupting, and the triggering side according to the interruption of determining carries out Interrupt Process then.In addition, MS also can detect the current state of CP and terminal automatically, is off-line state if detect the current state of CP or terminal, then determines to carry out Interrupt Process, with current state is that a side of off-line state is defined as the triggering side of interrupting, and carries out Interrupt Process according to the down trigger side that determines.MS can determine the triggering side of interruption according to the current state of CP and terminal, a side who is about to current state and is off-line state is defined as the triggering side of interrupting, be provided with the status service unit among the MS, store the current state of CP and terminal in this status service unit, therefore, MS can inquire the current state of CP and terminal by this status service unit, determines the triggering side of interrupting.
If the triggering side of interrupting is CP, cause terminal can't finish the download of shared data, then MS does not charge to terminal, further, if CP reaches the standard grade again, then MS allows terminal to continue to download from breakpoint, and notice terminal CP reaches the standard grade again, as MS periodically or repeatedly notify terminal CP to reach the standard grade again.After terminal is received the notice of MS, can connect with CP immediately, also can connect with CP, after terminal and CP connect, detect the shared data of having finished download, begin download of sharing data from breakpoint then in the moment after follow-up any CP reaches the standard grade again.Terminal also can no longer go up download of sharing data from the CP that initiates to interrupt, and directly abandons the download of corresponding shared data or selects other CP to download corresponding shared data, and at this moment MS just need charge to terminal.
If the triggering side of interrupting is a terminal, then MS charges to terminal, because terminal is not finished the download of shared data, therefore, MS can charge to terminal according to the flow of terminal download of sharing data, in the subsequent process, if corresponding terminal is downloaded corresponding shared data from CP once more, then MS allows terminal to continue to download from breakpoint, also can continue according to the flow of terminal download of sharing data terminal to be chargeed.
By Interrupt Process described above, make the rights and duties of CP and terminal in the shared data downloading process, obtain good embodiment, embodied the fairness of chargeing.
Step 212: terminal can be when the download of finishing shared data, disconnect with CP between be connected, send the request of finishing of downloading to MS then, this terminal of notice MS has been finished the download of shared data.
After step 213:MS receives that request is finished in download, whether the remaining sum of determining terminal is sufficient, if Sorry, your ticket has not enough value owing to terminal, then MS can be temporarily carry out authorisation process to the shared data of terminal downloads, return cause value to terminal, the notice terminal is supplemented with money, after terminal is supplemented with money, continues execution in step 214～step 215.If the remaining sum abundance of terminal, then execution in step 214～step 215.
Step 214～step 215:MS generates grant number, and returns this grant number to terminal after successfully terminal being chargeed.After terminal is received grant number, each data chunk of downloading is synthesized available shared data content, the shared data of downloading is used.If terminal can't be used shared data, then MS continues to provide CP to terminal, and this CP is for providing the CP of Downloadable corresponding shared data, and terminal is download of sharing data again, and at this moment, MS can not charge to terminal.
The relevant information of step 216:MS updated stored is applied on the account as the deduction with expense, and the number of times that shared data is downloaded is finished in change, upgrades download list, and the record of terminal in download list that shared data is downloaded finished in deletion.
Step 214～step 215 does not have tangible sequencing in time with the execution of step 216.
In the process of terminal download of sharing data, other-end can ask to connect with this terminal, this terminal can judge whether to connect with corresponding terminal, if, then connect with corresponding terminal, need download this terminal during the data downloaded piece at corresponding terminal then, provide respective data blocks to corresponding terminal; Otherwise this terminal refusal connects with corresponding terminal.A terminal can limit the quantity of coupled other-end, sets maximum connection value, and when coupled other-end quantity reached the maximum connection value of setting, if receive connection request from certain terminal again, then refusal connected with corresponding terminal.
