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.
