The P2P technology is also referred to as peer-to-peer network (Peer to Peer) technology, and this is a kind of thought of network configuration.It with present network in the essential distinction of client/server (Client/Server) structure of dominate be not have Centroid (or central server) in the whole network configuration.In the P2P structure, each node (peer) has the function of three aspects such as information consumer, informant and information communication mostly simultaneously.The rights and duties that each node had in the P2P network all are reciprocity.
Portable terminals such as mobile phone are nowadays by people's extensive use, come transfer files also very general by portable terminal, the user often wishes the data in the own mobile phone are shared other users, if adopt traditional sharing mode, data in this machine of being about to are set to share, other users directly obtain data from this mobile phone, terminal that must the shared data place is communicated with wireless network when other users obtain data always, if user shutdown or be connected interruption with cordless communication network, then other users just can't get access to data, and as a plurality of users simultaneously when this terminal is obtained shared data, to be subjected to the restriction of this terminal wireless access bandwidth, professional effect is unsatisfactory.The P2P technology can increase the data source in the network, makes data obtain taker and needn't leave no choice but obtain data from the supplier of initial data, and still there are the following problems in the moving communicating field but the P2P technology is applied to:
1, portable terminal can not be in open state easily always as computer, and the BT mode generally needs computer to be in open state for a long time, and especially portable terminal still needs to be in connection status in that initial data is published to always before other portable terminals in the mobile communications network.
2, portable terminal needs at first to communicate by wireless signal and base station, then just can access network, its radio channel resource is limited, can't satisfy communicating to connect between a large amount of portable terminals, and be subjected to the influence of the frequent mobility of communicating pair terminal, wireless signal and Network Transmission situation.
In addition, because still there is similar problem in the influence of bandwidth in the wire communication field, for example the user by dialling up on the telephone because its access bandwidth is limited, is difficult to the data in its communication terminal are shared many people.
Summary of the invention
The objective of the invention is to carry a kind of data sharing method of communication terminal, to reduce the influence of transmission bandwidth to shared data transmission, and can make communication terminal convenient get access to shared data, the Network Transmission situation of communication terminal that reduces the issue shared data simultaneously is to the influence of shared data transmission.
For achieving the above object, the invention provides a kind of data sharing method of communication terminal, comprise the steps:
After step 1, first communication terminal are received data sharing instruction, with the shared data server of shared data transmission in the network, this shared data of shared data server stores;
Step 3, described shared data server are according to the second communication terminal information of carrying in this request message, to second communication terminal transmission data
As shown from the above technical solution, the present invention has following beneficial effect:
1, in the acquisition process of shared data, the communication terminal that obtains shared data can be by the communication terminal of issue shared data, navigate on the shared data server in the network, obtain shared data, rather than go to obtain data from communication terminal itself, do not issued the restriction of Network Transmission bandwidth of the portable terminal of shared data like this, thus maximal efficiency utilize the existing network bandwidth, save network traffics.
2 after the communication terminal that obtains data navigates to the shared data server, follow-up data transmission procedure, do not need to issue the participation of the communication terminal of shared data, do not obtain shared data even shutdown of the communication terminal of cloth shared data or network connection state difference also can not influence communication terminal.
3, because the process that the user obtains shared data is the communication terminal that navigates to the issue shared data earlier, then, navigate in the share service device by this communication terminal, whole process is transparent for the user again, is the same with obtain shared data from communication terminal.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
