To achieve the above object of the invention, the present invention adopts following scheme:
A multiple terminals cooperative system based on tactful, its framework as shown in Figure 1.When target terminal needs transfer of data, first determine available collaborative terminal, then transmission request and collaborative end message are sent to collaborative gateway, collaborative gateway obtains collaborative strategy in conjunction with the network information gathering by strategic decision-making server from policy library, and according to this strategy to data shunt, parallel transmission, polymerization, thereby promoting transmission rate improve terminal and the utilance of network.
The specific descriptions of the unit relating in Fig. 1 are as follows:
Target terminal refers to work in coordination with the terminal that terminal is carried out cooperative transmission, and its function has:
1. search for its terminal signaling around; 2. with terminal interaction around, determine available collaborative terminal; 3. mutual with collaborative gateway, determine the collaborative terminal that participates in cooperative transmission; 4. participate in receiving or sending data; 5. to data aggregate or shunting.
Collaborative terminal refers to provide for target terminal the terminal of cooperative transmission service, and its function has:
1. mutual with target terminal, determining whether to provide cooperation with service for target terminal; 2. mutual with collaborative gateway, determine whether to participate in cooperation with service; 3. participate in receiving or sending data.
Collaborative gateway refers to, to the collaborative node that manages control in multiple terminals, belong to Policy Enforcement Point, and its function has:
1. collect the end message (terminal type, available network, operating system, available power etc.) of target terminal and available collaborative terminal, collection network information (network state, available resources etc.) and applied business information (type of service, resource requirement); 2. send the end message of collection, the network information and applied business information to strategic decision-making server; 3. receive and carry out the collaborative strategy from strategic decision-making server; 4. according to strategy, carry out service distributing or polymerization.
Tactical management server refers to the server that system manager manages collaborative strategy, and for system manager provides the interface to coordinated management operation, its function has:
1. system manager creates and allocation strategy by this interface; 2. the state of monitor network; 3. end-user verification mechanism is provided; 4. detect potential collaborative policy conflict.
Policy library refers to deposit the server of coordinated management strategy, and its function has:
1. deposit strategic server according to network state, business demand and collaborative terminal attribute (such as, dump energy, mobility, OS Type etc.) etc. information (such as, system energy consumption is minimum, throughput of system is maximum, system downloads time delay minimum etc.) under certain optimization aim be generated as the collaborative strategy that different terminals distributes different business.; 2. strategy retrieval is provided.
Strategic decision-making server is according to the information of collaborative gateway collection, to make the server of Coordination Decision, and its function has:
1. receive the information gathering from collaborative gateway; 2. corresponding tactful to policy library inquiry according to these information; 3. decision strategy inquiry being obtained is sent to collaborative gateway; 4. detect collaborative tactful conversion and conflict, and correct the problem occurring.

If 5. contain corresponding collaborative strategy in policy library, from policy library, obtain corresponding collaborative strategy, and be back to collaborative gateway; Otherwise to tactical management server, tactical management server is back to collaborative gateway by strategic decision-making server after generating corresponding collaborative strategy by these information reportings, and by this policy store in policy library.
Strategic server according to network state, business demand and collaborative terminal attribute (such as, dump energy, mobility, OS Type etc.) etc. information (such as, system energy consumption is minimum, throughput of system is maximum, file download time delay minimum etc.) under certain optimization aim be generated as the collaborative strategy that different terminals distributes different business.For example, for the streaming media service based on SVC coding, preferential select operating system identical with target terminal, download basal layer with the target terminal collaborative terminal less and that Link State is stable that relatively moves, select that operating system is different from target terminal, and target terminal relatively moves greatly and the unsettled collaborative terminal of Link State is downloaded enhancement layer.And for file downloading service, preferentially select the collaborative terminal that downloading rate is larger to download.
6. collaborative gateway according to collaborative strategy by data distribution to each collaborative terminal and target terminal
7. collaborative terminal is sent to target terminal by the data of downloading separately, and is completed and converged by target terminal.
2) the collaborative method for uploading in the multiple terminals based on tactful, as shown in Figure 3, comprises the following steps:
1. target terminal is searched for available collaborative terminal
2. target terminal will be worked in coordination with end message and application demand information reporting to collaborative gateway
3. collaborative gateway reports strategic decision-making server by end message, application message and the network information
4. strategic decision-making server is according to whether containing corresponding collaborative strategy in reporting information query strategy storehouse;
If 5. contain corresponding collaborative strategy in policy library, from policy library, obtain corresponding collaborative strategy, and be back to collaborative gateway; Otherwise to tactical management server, tactical management server is back to collaborative gateway by strategic decision-making server after generating corresponding collaborative strategy by these information reportings, and by this policy store in policy library.
6. collaborative gateway will be worked in coordination with strategy and be sent to target terminal;
7. target terminal according to collaborative strategy by data distribution to each collaborative terminal and collaborative gateway;
8. collaborative terminal is extremely worked in coordination with gateway by responsible separately data upload, and completes polymerization by collaborative gateway.
In a word, a kind of multiple terminals cooperative system and method based on tactful provided by the invention, belongs to network communication field.The present invention is first by collaborative definite available terminal of a plurality of terminal rooms, then according to Information Selection such as available terminal ability, current network resources and applied business demands, participate in collaborative terminal and transmit for the corresponding Business Stream of selected terminal distribution, finally the Business Stream by selected terminal transmission is converged, realize the collaborative work of multiple terminals.The method not only can be given full play to the ability of each terminal equipment, can also realize distributing rationally of Internet resources, improves network resource utilization, and then promotes customer service experience, and this invention has great theory value and using value.
