Definition of A Session：
A service session is a logical entity.
Independent of transmission direction.
It is basically described as the period where a user is actively using the service.
During an active service session, the network must maintain connectivity between the users in that session.
Definition of A Burst：
The Burst represents a block of real traffic that the application sends/receives.
The Burst is the activity that the bearer channels in the network see.
For many services, a burst equates to the transfer of a file or message.
The burst is uni-directional (uplink and downlink bursts are different).
