Structure and transportation of 3G(WCDMA)technology
Zhang Li · Journal of Liaoning Technical University · 2006
The objective of this article is to prove that IP protocol will be the bearer of the WCDMA core network. The article first introduces the structure of WCDMA and analyses the core network of WCDMA and NGN structure. The NGN is the network that can be divided by switching function layer and transport layer. By analyzing IP protocol and ATM protocol stack of bearing voice signal, the band with one voice channel is heard by IP and ATM use is calculated. So we can draw a conclusion that we should use IP protocol as the protocol of the transport layer. In other words, IP protocol will be the load bearing core.
