Questions about radio resource allocation in 3G data network

Hi everyone,

I have some specific question about radio resource allocation in 3G data 
network. 



In  the UMTS 3G data network, the smartphone has to acquire radio resource  from 
RNC before it can talk to any server on the Internet. Allocating  radio resource 
usually takes a few seconds (2+ seconds) to complete and  thus causes delays to 
the smartphone applications. This process will  involve RRC connection setup and 
radio  bearer reconfiguration.
