Abstract

The invention discloses a data transmission method, device and system. The data transmission method comprises: determining that a connection is established between a first terminal and a second terminal; obtaining identification information of a first client disposed in the first terminal; and transmitting the identification information to a second client disposed in the second terminal. By employing the invention, the problem can be solved in which since data transmission can not be conducted between different clients, user requirements must be re-introduced when a new client is enabled, thereby resulting in resource waste and low efficiency.

First claim

1 . A first terminal, comprising:
a first client; a memory having instructions stored thereon; and a processor configured to execute the instructions to perform operations for data transmission, the operations comprising:
determining that the first terminal is connected with a second terminal;
obtaining identification information of the first client and data in the first client;
transmitting the identification information to the second terminal;
transmitting the identification information and the data to a corresponding persistent connection server via a first server of the first terminal; and
further transmitting the data to the second client by the persistent connection server.

2 . The first terminal as in claim 1 , the operations further comprising:
sending an address request message to a persistent connection allocation server, wherein in the address request message is carried the identification information; and receiving a response message returned by the persistent connection allocation server, wherein in the response message is carried the address information of the persistent connection server.

3 . The first terminal as in claim 1 , wherein the data in the first client comprises at least one of the following:
network addresses collected in the favorites of the first client; commonly used network addresses of the first client; a network address currently opened by the first client; and user data invoked by the first client according to a user instruction.

4 . The first terminal as in claim 1 , wherein the identification information comprises any of the following:
account information logged in by a user of the first client; and a unique identification generated for the first client.

5 . The first terminal as in claim 1 , wherein the first terminal is connected with the second terminal via a USB data line.

6 . The first terminal as in claim 1 , wherein the first client and/or the second client is/are a browser client.

7 . The first terminal as in claim 1 , the operation of transmitting the data to the second client further comprising:
determining whether to forward the data of the first client to the second client according to a persistent connection state of the second client and the persistent connection server.

8 . The first terminal as in claim 1 , the operation of transmitting the identification information and the data to a corresponding persistent connection server via a first server of the first terminal comprising:
performing security verification on the data in the first client and its identification information by the first server; and forwarding the data in the first client and its identification information which pass the security verification to the persistent connection server which is determined according to the identification information of the first client.

9 . The first terminal as in claim 8 , wherein the data of the first client which passes the security verification is non-malicious data, and the identification information of the first client which passes the security verification is identification information of the first client which has been registered in the first server.

10 . The first terminal as in claim 7 , the operation of determining whether to forward the data of the first client to the second client according to a persistent connection state of the second client and the persistent connection server comprising:
forwarding the data of the first client to the second client when the persistent connection state of the second client and the persistent connection server is a connected state; and storing the data in the first client in the persistent connection server when the persistent connection state of the second client and the persistent connection server is a non-connected state; and sending the stored data in the first client to the second client by the persistent connection server when the state of the persistent connection between the second client and the persistent connection server is turned from a non-connected state to a connected state.

11 . The first terminal as in claim 7 , the operation of determining the persistent connection state of the second client and the persistent connection server comprising:
querying about the persistent connection state of the second client and the persistent connection server in an online device list stored in the persistent connection server, wherein in the online device list is stored identification information of individual clients which have established persistent connections with the persistent connection server; determining the persistent connection state of the second client and the persistent connection server to be a connected state if the identification information of the second client is queried out; and determining the persistent connection state of the second client and the persistent connection server to be a non-connected state if the identification information of the second client is not queried out.

12 . A second terminal, comprising:
a second client; a memory having instructions stored thereon; and a processor configured to execute the instructions to perform operations for data transmission, the operations comprising:
determining that the second terminal is connected with a first terminal;
receiving identification information of a first client disposed in the first terminal sent by the first client;
obtaining the identification information and searching for address information of a corresponding persistent connection server according to the identification information; and
establishing a persistent connection between the second client and the persistent connection server according to the obtained address information, such that the second client receives data from the persistent connection server;
wherein the operation of searching for address information of a corresponding persistent connection server according to the identification information comprising
sending an address request message to a persistent connection allocation server, wherein in the address request message is carried the identification information; and
receiving a response message returned by the persistent connection allocation server, wherein in the response message is carried the address information of the persistent connection server.

13 . The second terminal as in claim 12 , after the operation of establishing a persistent connection between the second client and the persistent connection server, the operations further comprising:
receiving data from the persistent connection server, wherein the data is data which is uploaded to the persistent connection server by the first client; and performing processing by the second client according to the data.

14 . The second terminal as in claim 13 , wherein the data comprises at least one of:
individual network addresses collected in the favorites of the first client; commonly used network addresses of the first client; a network address currently opened by the first client; and user data invoked by the first client according to a user instruction.

15 . The second terminal as in claim 14 , wherein the operation of performing processing by the second client comprises at least one of:
the second client updating the favorites; the second client updating the commonly used network addresses; and the second client opening a webpage corresponding to a network address.

16 . The second terminal as in claim 12 , wherein after the operation of receiving the identification information of the first client, if it is q
