Lift a concrete instance below scheme provided by the invention is carried out exemplary illustration, specifically see also Fig. 5 to Fig. 8.
Fig. 5 is that the multimedia content distribution system based on the CDN-P2P technology provided by the invention is formed sketch map.
As shown in Figure 5, this system links to each other with core IMS network, comprises association changer controller 501, Streaming Media controller 502 and stream media distribution server 503.
Wherein, switch controller 501 is used for when user node request streaming media switch content (for example channel switching or fast forwarding and fast rewinding etc.), carrying out switching controls.
Stream media distribution server 503 is used for to the user node distributing multimedia contents.
Multimedia content distribution system shown in Figure 5 subject matter to be solved comprises two: first problem is the management that makes things convenient for multimedia content distribution system, reduce the load pressure to network side node; Second problem can change the broadcast mode of multimedia video when being to use the family under the IMS environment, to use the terminal to watch multimedia video, for example F.F. or rewind down realize that perhaps fast channel switches.
To first problem, through in stream media distribution server, storing content of multimedia, between user node, carry out traffic sharing, and adopt the form of multimedia multicast tree to organize between user node and solve.To second problem, solve through switch controller 501, thereby, realize seamlessly transitting carrying out that channel switches or during handover operation such as fast forwarding and fast rewinding, can searching out switching point fast, improve user experience.
Referring to Fig. 5; Can adopt heartbeat (HeartBeat) message to carry out synchronously between Streaming Media controller 502 and the stream media distribution server 503, thereby make Streaming Media controller 502 obtain content source information and the progress msg that each user node obtains content of multimedia.
Stream media distribution server 503 can insert a plurality of user nodes; Form a multicast tree respectively under each user node in the ground floor user node (user node that promptly links to each other) with stream media distribution server 503; No matter be that channel switches the fast forwarding and fast rewinding (progress under the promptly unified content of multimedia source is switched) in (being the switching between the content of multimedia source) or the channel, all accomplish with the switching between switching of the node structure in the multicast tree or multicast tree.
Be that example is introduced with the fast forwarding and fast rewinding scene in the channel below:
Suppose that each user node can deposit the content of multimedia of wrong 5s duration; Can adopt the P2P mode to carry out content sharing between the user node; The user node that inserted in promptly first second can provide sharing of content for the user node that inserts within the 5th second; Then these user nodes have been formed a multicast tree, specifically can be referring to Fig. 5.
Therefore the user node that inserted in first second can directly be controlled the content of multimedia of storage on the stream media distribution server 503 owing to directly connected stream media distribution server 503.Other nodes on the multicast tree at this user node place then can be controlled the part content of multimedia, the content that for example user can F.F. 5S.But the content of F.F. longer time then need be carried out the variation on the topology to multicast tree if desired, specifically can be referring to Fig. 5 and Fig. 6.
Fig. 6 is that the child node among Fig. 5 is carried out the sketch map after the content of multimedia progress is switched.
Among Fig. 6, child node 5 F.F.s promptly entered into 35 seconds contexts in 30 seconds, need the ground floor father node under the whole Streaming Media controller 502 of traversal earlier, search out first and lack 5 seconds father node than its content and be connected to then under this multicast tree.Switch for level and smooth realization, allow the node of this switching to be linked under a plurality of father nodes of this multicast tree,, slowed down the switching problem of bringing when switching out of stock greatly, improved user experience because a plurality of father nodes transmit content of multimedia to this node simultaneously.As shown above, it is to become node 35 under the multicast tree of father node that child node 5 moves on to 30s, has connected 31s and two nodes of 32s this moment simultaneously, and two nodes carry out the content distribution to this node 35 at a high speed simultaneously, have realized seamlessly transitting of switching.After waiting for a period of time, this node 35 can select the some nodes in father nodes to carry out transfer of data, and purpose is to reduce the flow load of whole network, and the selection of node is according to this section data traffic node relatively stably in the time.
What describe about the handoff procedure of Fig. 6 is the process that child node is switched.If father node switches, then process can be more complicated than child node handoff procedure, specifically sees also Fig. 5 and Fig. 7.
Fig. 7 is that the root node among Fig. 5 carries out the sketch map after the content of multimedia progress is switched.
As shown in Figure 7, detailed process is following:
If the needs of root node switch; The process that its root node itself is sought multicast tree is similar to the process that child node is sought multicast tree; Promptly travel through stream media distribution server 503 following ground floor father nodes; Seek than the node of oneself turn-on time, join again in the multicast tree under this node less than scheduled duration.Can to seek a plurality of father nodes equally and connect in order to realize seamlessly transitting.
Comparing the step that needs to increase with the child node switching comprises: the root node that request is switched belonged to multicast tree in the past and need be connected stream media distribution server 503 again and form a new multicast tree.This mode can for: remove the node that inserts the earliest in the node beyond the said root node under this multicast tree and can be connected on the stream media distribution server 503, form a new multicast tree thereby other nodes connect this node again.
Referring to Fig. 7; Thereby node 1 F.F. be linked in the new multicast tree in 33 seconds and become node 34; The ground floor father node of this multicast tree is the 30th second node that inserts; This node receives the transfer of data of 31s and 32s node simultaneously, treat a period of time after, switching node has selected the node of 31s to carry out transfer of data.And the multicast tree before this root node sorts again, forms a new multicast tree, and particularly, the root node of new multicast tree is the 2nd second node that inserts.
If the node that request is switched is a father node, then with root node switch similar, the father node child node down that this request is switched be articulated to this father node other father nodes together layer on, perhaps be articulated on the father node of this father node last layer.
It should be noted that in addition each stream media distribution server 503 need safeguard state informations such as the play content of all user nodes under the book server, turn-on time, in progress time.When each user node switched, user node can obtain the information of other user nodes from this server like this, thereby correctly carried out the switching of multicast tree fast.502 of Streaming Media controllers can obtain the state information of all stream media distribution server 503 storages, and user node also can obtain the state information of the user node on other multicast tree through the stream media distribution server 503 that self belongs to from Streaming Media controller 502.
In video display process, carrying out playing progress rate with user node UE1 below and switch, is example with video source from the scene that user node UE2 switches to UE3, and the message flow in the play content handoff procedure is introduced, and specifically sees also Fig. 8.
Fig. 8 is the message flow chart in the play content handoff procedure provided by the invention.
As shown in Figure 8, this flow process comprises:
Step 6, (User ProfileServer Function UPSF) searches UE3 user profile to multimedia content distribution system to the user configuration information service entities.
Step 7, UPSF returns the user profile of UE3 to multimedia content distribution system.
Step 8, multimedia content distribution system are initiated to connect to set up to UE1 and are ordered.
Step 9, (Serving Call Session ControlFunction S-CSCF) sends connection and sets up request UE1 to service call session control function entity.
Step 10, S-CSCF will connect the request of foundation and be transmitted to UE3.
Step 11, UE1 and UE3 begin to connect.
Step 12, UE1 is in UE3 and is connected the state of foundation, and UE1 obtains video resource from UE3 in this example, accomplishes change action.
The difference that the method for (being that channel switches) and multimedia progress switching (being F.F. or rewind down) is switched in the content of multimedia source only is; It is to switch in the multicast tree under same content source or between multicast tree that the multimedia progress is switched, and switch in the content of multimedia source then is between the multicast tree under the different content source, to switch.For example; User node in the multicast tree under the first content source (for example channel 1) need switch to second content source (for example channel 2); Then at first search the multicast tree under this second content source; Selection can provide the multicast tree of the content of multimedia progress of its request for this user node, and this user node is articulated on the user node under this multicast tree.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
