Connection Timer
The Connection Timer adds the ability to periodically check whether the UE, while in the RRC Connected
state, is still able to communicate with the PXT. An example of where this would not be the case is where
the UE has been physically disconnected from the PXT without being turned off, and going through the
Detach procedure.
If the Connection Timer is enabled (using the Connection Timer Status field), a transport block filled with
MAC padding data is occasionally sent to the UE. If this is ACKed or NACKed, it will be taken as a sign that
the UE is still present. If the UE does not send an ACK or NACK for the number of seconds specified in the
Connection Timer field, the UE is assumed to have disconnected and the state of the PXT changes to Idle.

Inactivity Timer Status
The Inactivity Timer monitors whether the UE is sending or receiving any data on an SRB or DRB. If no RLC
activity is detected for the number of seconds specified by the Inactivity Timer setting, an RRC Connection
Release is automatically sent to the UE. The behavior is turned off while receiver testing is in progress (for
example, during Statistical Throughput). This behavior mirrors the behavior in some networks where UEs
are only allowed to remain in the RRC Connected state while they are actively using the services of that
network. Sending the UE to the RRC Idle state frees up network resources and saves UE battery life.
