

3.  On receiving the Activate PDP Context message, the Core 

Network checks the user's subscription record to establish 
whether the request is valid. If the request is valid, a 
virtual connection is established between the Terminal and 
the Core Network, and data transfer can then take place 
between the Terminal and the external data network, 
within the scope of the current PDP Context. The PDP 
Context is stored in both the Terminal and the Core 
Network. 
 

A single Terminal may have multiple PDP Contexts each with 
different QoS profiles. The primary PDP Context is a PDP 
Context with default QoS profile attributes and is always 
activated first. All other PDP Contexts with the same PDP 
Address are secondary PDP Contexts. Secondary PDP Contexts 
share the same PDP Address and connect to the same APN but 
may have different QoS profiles.
