Embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
As shown in Figure 1a, it is the networking structure of data conferencing document sharing of the present invention system, the document shared system 1 comprises at least two terminals (terminal 1, terminal 2) and a Media Resource Server MRS (Multimedia Resource Server) 30 who links to each other by network 20, has also set up an application server AS (Applicant Server) 40.This application server AS 40 also can be set as to be had the module identical with its function and is integrated among the Media Resource Server MRS 30.Network 20 can be an IAD.
Be example with terminal 1,2 two terminals of terminal among Fig. 1 a, one of them terminal label is UE# 1, and as the host, another terminal label is UE# 2, as conference member; Application server AS 40 is used for the control of data conferencing, Media Resource Server MRS 30 be responsible for and terminal 1,2 between to carry out media information mutual.
Application server AS 40 is carried out Signalling exchange and is created XMPP data conferencing passage between XMPP data conferencing passage, terminal 2 and the Media Resource Server MRS 30 between data conferencing, terminal 1 and the Media Resource Server MRS 30;
The file of this enactment document form is the blank page or leaf, according to the attribute of blank page or leaf, the blank page or leaf can be divided into structural blank page or leaf (do not comprise documentation page and any pel, only represent a middle-level structure) and comprise the actual blank page or leaf of documentation page.Documentation page refers to the page or leaf that is generated by virtual printer, and the page or leaf in it and the document that needs to share is corresponding one by one.
Comprise a documentation page and a plurality of mark pel in the actual blank page or leaf, when reality is shared, send whole markup informations during each page turning, and documentation page wherein may be a link; The documentation page that whole page infos refer in the blank page or leaf is actual content rather than link.
Media Resource Server MRS 30 receives, preserves documentation page, and is transmitted to terminal 2 by XMPP data conferencing passage;
Shown in Fig. 1 b, be the method flow diagram of data conferencing document sharing of the present invention.This method flow is to utilize SIP (Session Initiation Protocol, Session initiation Protocol) carries out Signalling exchange, utilize XMPP (Extensible Messaging and Presence Protocol, scalable message is handled on-the-spot agreement) to carry out the mutual process of media information.SIP is used for initially, manages and stop the data session of packet network, particularly, is used to generate, revise and the session between one or more participants of terminating.This method flow specifically may further comprise the steps:
Step 101, UE# 1, promptly as host's terminal (or being called host's terminal), carry out the SIP Signalling exchange with MRS and create data conferencing and XMPP data conferencing passage, then invite other-end UE# 2 to add this data conferencing, also set up corresponding XMPP data conferencing passage between these terminal UE # 2 and the MRS simultaneously as conference member;
Step 102, UE#1 is converted to the blank formatted file by virtual printing with document, this document is self-defining file format, can preserve picture, vector graphics etc. simultaneously, for binary pels such as pictures, should carry out the Base64 coding to its content, so that can in XMPP data conferencing passage, transmit;
In this step, document can be the document of image format, also can be the document of vector format;
Step 103, UE#1 opens the blank formatted file, and page turning, and the link information with markup information, documentation page or documentation page in this blank page or leaf during page turning sends to MRS, writes down the documentation page that was sent simultaneously;
Step 104, MRS preserves documentation page according to the replacement policy of page or leaf, simultaneously the documentation page that receives is transmitted to UE#2;
Step 105, other conference members UE#2 accepts and shows, and the documentation page of sharing is kept in the internal memory temporarily, rather than is kept on the hard disk, thereby has certain fail safe;
Step 106, UE#2 can be to the operation power or the power control data of UE#1 request for data;
In this step, data manipulation power is meant, can use the blank instrument that documentation page is marked; Power control data is meant, can carry out page turning to document, can open new shared document, in document sharing is used, there is and can only have a participant to have power control data, but can have a plurality of participants to have data manipulation power, the founder of meeting can authorize or permission modification.
In the above-mentioned steps 102, the blank formatted file is based on the blank page or leaf, and each blank formatted file comprises a plurality of blank pages or leaves; Each blank page or leaf comprises essential informations such as page head and page attribute, and page attribute represents that current blank page or leaf comprises the actual blank page or leaf or the nested structural blank page or leaf that comprises next stage blank page or leaf of documentation page, can form with this and be similar to tree-like bibliographic structure.Actual blank page or leaf comprises the documentation page and the markup information that come through virtual printing conversion, has in the actual blank page or leaf and can only comprise a documentation page, but can comprise a plurality of mark pels simultaneously; The mark pel can be types such as various vector graphics, image, literal.
Because the documentation page in the blank page or leaf is to be printed through virtual printer by the document that needs are shared to generate, general big comparison, mostly more than the 100K byte, and in sharing, cannot revise, but the mark pel in the blank page or leaf can be revised and delete, so in the above-mentioned steps 105, should be to the documentation page of having browsed at MRS and UE# 2 local cache, and then the efficient and the synchronism of effectively conserve network bandwidth, raising page turning, be implemented as follows:
1), when UE#1 sends a certain blank page or leaf first, write down the documentation page that has sent in this blank page or leaf, when the document page or leaf need send once more, the link information that only sends the document page or leaf got final product.For guaranteeing the uniqueness of blank page or leaf, the ID of blank page or leaf and documentation page should adopt GUID (Globally Unique Identifier, the unified identifier of the overall situation), can guarantee after changing like this, can not produce the problem of blank page or leaf and documentation page ID conflict during page turning at power control data;
2), the documentation page of MRS buffer memory some, when receiving that documentation page is link information, in buffer memory, search the information of the document page or leaf, as do not find, then circularize UE# 1 and require to resend complete blank page information, if find, then documentation page directly is transmitted to UE# 2, and selects documentation page replacement policy/algorithm to preserve documentation page by MRS.
Wherein, the replacement algorithm of documentation page can adopt random algorithm (RAND), fifo algorithm (FirstIn First Out, FIFO), recent minimum use algorithm (Least Recently Used, LRU), do not use algorithm or least often use algorithm (Least Frequently Used at most, LFU) and page fault frequency method (Page Fault Frequency, PFF) dynamic page dispatching method etc., this example does not limit replacement policy;
3), when MRS sent a certain blank page or leaf first, record had sent to the documentation page in this blank page or leaf of UE# 2, when the document page or leaf need send once more, only sends the link information of the document page or leaf;
4), the UE# 2 buffer memory all or the documentation page of some, when receiving the documentation page that contains link information, in buffer memory, search corresponding documentation page, as do not find, circularize MRS and require to resend complete blank page information, if find, then show documentation page in this blank page or leaf, and select documentation page replacement policy/algorithm to preserve documentation page in this blank page or leaf by UE# 2.
Wherein, when buffer memory partial document page or leaf, should adopt the page replacement policy identical and the number of caching page, can guarantee that UE# 2 and MRS go up the consistency of the documentation page of buffer memory, and then improve the hit rate that url page is searched with MRS.
As shown in Figure 2, be the signaling process of data conferencing constructive process of the present invention, wherein main signaling is described below:
Step 201:UE#1 (host's terminal), send band SDP (Session Description Protocol, Session Description Protocol) INVITE () of information asks AS, the TCP link information (IP address and the port numbers that have this terminal among the SDP, be used for the foundation of XMPP data conferencing passage), and the data conferencing member who is invited tabulation;
In this step, the SDP agreement is to be used for describing the Multimedia session announcement, and Multimedia session is invited and the initialized agreement of other forms of Multimedia session.
The SIP signaling that step 202～204:AS forwarding UE# 1 sends to AS is to MRS, and MRS indicates the conference member number according to SDP information creating data conferencing; If create successfully in the meeting-place, then reply 200OK (), AS returns ACK () after receiving answer;
Step 205～209: if data conferencing is created successfully, AS sends INVITE () signaling to MRS, request adds this meeting with UE# 1, obtain response 200 OK () of MRS success, and return ACK () to MRS, to return MRS to UE# 1 be the ready media channel information of UE# 1 to AS then, sets up XMPP data conferencing passage between UE# 1 and the MRS;
Step 210～218: for other conference members (UE#2) are added among the MRS, AS sends the INVITE signaling to MRS, be UE# 2 application IMS conference medium passage, MRS replys 200 OK (), AS returns ACK () after receiving answer, but the media information of the UE# 2 that uses is a virtual information, be used to obtain the media information of MRS, AS then sends the INVITE signaling that has the MRS media information and invites UE# 2 to add data conferencing, if UE# 2 adheres to meeting, the media information that then in replying signaling 200 OK (), adds oneself, and sending to AS, AS revises the media information of the UE# 2 on the MRS by sending the RE-INVITE signaling to MRS then, MRS replys 200 OK (), and AS returns ACK () after receiving answer; And then MRS notice UE# 2, the MRS resource is ready, can set up correct XMPP data conferencing passage between MRS and the UE# 2;
Step 219～220:AS is by SIP signaling UE# 1, and UE# 2 has added meeting, and UE# 1 replys 200 OK () to AS.
So far data conferencing and special-purpose XMPP data conferencing passage thereof are created and are finished.
As shown in Figure 3, be the signaling process figure that establishment document sharing of the present invention is used, this flow process has been described and has been created the signaling process that data conferencing document sharing is used, and specifically describes as follows to wherein main signaling:
Step 301:UE#1 (host's terminal) applies for creating the document sharing media channel to the RE-INVITE () signaling that AS sends tape file transmission SDP information;
Step 302～304:AS transmits UE# 1 and sends to the SIP signaling of AS to MRS, be the media channel that the UE# 1 application document is shared, MRS sets up the media channel of document sharing according to SDP information, if success, then reply 200 OK (), AS returns ACK () to MRS after receiving answer;
Step 305～306:AS sends the SDP information of the passage of 200 OK () notice UE# 1 MRS distribution, and UE# 1 returns ACK () to AS, and UE# 1 and MRS set up the document sharing media channel;
Step 307～309:AS sends the RE-INVITE () signaling of the document sharing SDP information of virtual band UE# 2 to MRS, for UE# 2 to MRS application document shared medium passage, if success, MRS replys 200 OK (), and AS returns ACK () to MRS after receiving answer;
Step 310～311:AS sends RE-INVITE () signaling to UE# 2, invites UE# 2 opening document shared medium passage, if UE# 2 agrees that then add the media information of oneself in replying signaling 200 OK (), AS obtains the document sharing SDP information of UE# 2;
Step 312～314:AS sends RE-INVITE () signaling to MRS, upgrades the media information document sharing SDP information of the UE# 2 on the MRS, and replys 200 OK () to AS, and AS returns ACK () to MRS after receiving answer.
Step 315:AS sends ACK (), notice UE# 2, and the MRS resource is ready, can set up the document sharing media channel.
So far, application of document sharing and document sharing media channel thereof are created successfully.
As shown in Figure 4, be the medium signaling process figure of data conferencing document sharing of the present invention, this medium signaling process specifically comprises:
Step 401:UE#1 (host's terminal) opens the blank formatted file, during page turning, sends the blank page information by XMPP data conferencing passage to MRS;
In this step, if current blank page or leaf is to send for the first time, then send whole blank page informations and the documentation page in the blank page or leaf be labeled as and send page or leaf, and if the documentation page in the current blank page or leaf had sent, then when sending the document page or leaf once more, only send the link information of the document page or leaf;
Step 402: if MRS receives the documentation page of UE# 1 is link information, and the information that does not have the document page or leaf on the MRS, then send iq (Information Query information inquiry to UE# 1, be similar to HTTP, also be a kind of message of request formula) request message, ask complete blank page information.And, select rational documentation page replacement policy/algorithm to preserve documentation page in this blank page or leaf simultaneously if complete blank page information then directly is transmitted to UE# 2;
The iq request message of step 403:UE# 1 response MRS is replied complete blank page information;
Step 404:MRS transmits to UE# 2 by XMPP data conferencing passage and send the blank page information.If current blank page or leaf is to send for the first time, then send whole blank page informations, and the member that transmitted of record, otherwise, only send the link information of the documentation page in this blank page or leaf;
Step 405: if the documentation page in the blank page or leaf that UE# 2 receives is a link information, and UE# 2 does not find corresponding documentation page in this locality, then send the complete blank page information of iq message request to MRS, otherwise show the documentation page in this blank page or leaf, select rational documentation page replacement policy/algorithm to preserve documentation page in this blank page or leaf simultaneously;
The iq request message of step 406:MRS response UE# 2, reply complete blank page information to UE# 2, and if do not find corresponding complete blank page information, can take MRS directly to reply mistake, perhaps MRS is to the complete blank page information of UE# 1 request, and then is transmitted to method such as UE# 2;
Step 407～408:UE# 1 marks current blank page or leaf, and markup information is sent to MRS, and MRS (markup information of the blank page or leaf of MRS buffer memory current active) preserves and transmits corresponding mark message and gives UE# 2.
As shown in Figure 5, be the authority application flow chart of data conferencing document sharing of the present invention, this authority application flow process specifically comprises:
Step 501～502, UE#2 (rank-and-file member of conference participation) sends the INFO () message that has the applying right limit information to AS, and AS replys 200 OK () to UE# 2;
Step 503～504:AS gives UE#1 (host's terminal) with the INFO () forwards that the UE# 2 application is authorized, and UE# 1 replys 200 OK () to AS;
Step 505～508:AS sends INFO () message to UE# 2, change UE# 2 and be " applying for control or operation power " at the state of data conferencing, UE# 2 replys 200 OK () to AS, and AS transmits this INFO () message and gives UE# 1, and UE# 1 replys 200 OK () to AS;
Step 509～510:UE# 1 passes through INFO () message to AS return authorization result---authorizes;
Step 511～513:AS sends to MRS with RE-INVITE () message, and revising the XMPP data conferencing passage of UE# 2 on MRS is " sendrecv ", and MRS replys 200 OK () to AS, and AS returns ACK () after receiving answer;
Step 514～515:AS sends to UE# 2 and has the INFO () message of applying for successful result, and notice UE# 2 obtains in the control of data conferencing document sharing application or operation power, and UE# 2 replys 200 OK () to AS;
Step 516～518:AS sends RE-INVITE () message to UE# 2, and the XMPP data conferencing passage of revising UE# 2 is " sendrecv ", and UE# 2 replys 200 OK () to AS, and AS returns ACK () after receiving answer;
It is the INFO () message of having a say that step 519～522:AS has the UE# 2 state to the UE# 1 transmission, notifies the conference site state of all participants to change: UE# 2 obtains control or operation power; UE# 1 replys 200 OK () to AS, and it is the INFO () message of having a say that AS has the UE# 2 state to the UE# 2 transmission, and UE# 2 replys 200 OK ().
