Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to a kind of data service communications method, equipment and system.
Background technology
At present, in the middle of mobile communications network, two terminals belonging to identical strategy and charge execution function server (policyandchargingenforcementfunction, PCEF) carry out Point-to-Point Data service communication process as shown in Figure 1 after reaching the standard grade.
Wherein, first terminal 1 communicates with PCEF, completes line process (step 101,102,103,104), and in this process, PCEF is that terminal 1 distributes an IP address (i.e. IP1); The upper line process (step 105,106,107,108) of terminal 2 is similar to terminal 1, and PCEF is that terminal 2 distributes the 2nd IP address (i.e. IP2).Then, terminal 1 logs in point-to-point application server (step 109,110,111) and reports a described IP address, and point-to-point application server will preserve an IP address of terminal 1; Terminal 2 logs in point-to-point application server (step 112,113,114) and reports described 2nd IP address, and point-to-point application server will preserve the 2nd IP address of terminal 2.In addition, after, when terminal 1 will send communication data to terminal 2, such as, during file, terminal 1 first accesses the 2nd IP address (step 115,116) that point-to-point application server obtains terminal 2; Then, communication data is sent to PCEF(step 117 by terminal 1), by PCEF again by file transfer to terminal 2(step 118).The response message of terminal 2 is also sent to terminal 1 by PCEF.
In above-mentioned communication process, terminal must obtain the IP address of target terminal by point-to-point application server, and then completes the transmission of communication data.Namely account registered on point-to-point application server, password login point-to-point application server must be adopted to obtain the IP address of terminal B after, just data communication can be carried out, therefore user operation is more loaded down with trivial details, causes the data service communications inefficiency between terminal.
