Description

Data service communication method, device and system

Technical field

The present invention relates to the field of mobile communication technologies, and in particular, to a data service communication method, device, and system.

Background technique

At present, in the mobile communication network, two terminals belonging to the same policy and charging enforcement function (PCEF) are online, and the peer-to-peer data service communication process is as shown in FIG. 1 .

First, the terminal 1 communicates with the PCEF to complete the online process (steps 101, 102, 103, and 104). In the process, the PCEF allocates the first IP address (ie, IP1) to the terminal 1; and the online process of the terminal 2 (step 105, 106, 107, 108) Similar to terminal 1, PCEF assigns terminal 2 a second IP address (ie, IP2). Then, the terminal 1 logs in to the peer-to-peer application server (steps 109, 110, 111) to report the first IP address, and the peer-to-peer application server stores the first IP address of the terminal 1; the terminal 2 logs in to the point-to-point application server (steps 112, 113, 114) The second IP address is reported, and the peer-to-peer application server will save the second IP address of the terminal 2. Then, when the terminal 1 is to send communication data, such as a file, to the terminal 2, the terminal 1 first accesses the peer-to-peer application server to obtain the second IP address of the terminal 2 (steps 115, 116); then, the terminal 1 transmits the communication data to the PCEF. (Step 117), the file is forwarded by the PCEF to the terminal 2 (step 118). The response information of the terminal 2 is also transmitted to the terminal 1 through the PCEF. In the above communication process, the terminal must obtain the IP address of the target terminal through the peer-to-peer application server, and then complete the transmission of the communication data. That is to say, it is necessary to use the account registered on the peer-to-peer application server, the password login point to the point application server to obtain the IP address of the terminal B, and then the data communication can be performed, so the user operation is cumbersome, resulting in inefficient communication of data services between the terminals. .
