2) can utilize the PSTN network, reduce, especially reduce inserting taking of layer bandwidth to IP network.For mobile phone, more practical;
3) fixed line carrier can easierly carry out rate control.
For these reasons, at present industry has proposed voice and image are carried on technology on the heterogeneous networks respectively, is implemented as follows:
Prior art is with reference to Fig. 1, and the specific implementation process comprises the steps:
1:T1 and T2 two equipment are set up calling on the PSTN network, T1 calls out the PSTN number of T2, and continues;
2:T1 and T2 for example transmit the IP address by DTMF (dual-tone multifrequency) by PSTN circuit transmission both sides' IP address (having at least a side to transmit gets final product).
3: after obtaining the IP address, both sides initiate point-to-point call (having a side to initiate to get final product).
After the call setup success of 4:IP network, view data is transmitted on IP network, and voice bearer is at PSTN.
In the above-mentioned video communication process,, also need on IP network, set up server in order to solve the NAT that T1 and T2 are private network IP addresses (network address conversion) crossing problem.For example T1 and T2 support STUN (User Datagram Protoco (UDP) UDP is to the simple traversal mode of NAT), need to exist STUN Server on the network.
If what at first initiate is that IP network is called out, after call setup, transmit both sides' PSTN number by IP network, then need pre-configured loCal number (consider the situation of trunk call, need the loCal number of configuration band area code).
Therefore, there is following shortcoming in prior art:
1, when being used for connecting the scene of PSTN network after elder generation connects IP, need pre-configured loCal number (to consider the situation of trunk call, the loCal number that needs configuration band area code), as local switch do not accept with the local call of area code then this scheme can't implement.If reconfigure again when this terminal is used for other subscribers feeder simultaneously, use inconvenient;
2, under some networking scene, for example under NGN (next generation network) networking, the equipment that has had the supporting NAT of providing to pass through on the network increases STUN Server more at this moment and can cause overlapping investment.And this scheme can't be used existing device;
3, under some networking scene, for example under the NGN networking, wish processing such as traffic measurement or authentication and accounting are also carried out in the video communication on the IP network.If direct point to point call then can't realize.
