How can I keep the RRC connection active while switching off the UE and then switch it back on to establish another RRC connections?

How can I keep the RRC connection active while switching off the UE and then switch it back on to establish multiple RRC connections?

I want to perform the following sequence:
* Keep the RRC connection established between the UE and eNB active, even while the UE is switched off.
* Once the UE is switched back on, I want to establish another RRC connections between the UE and eNB.

However, I have encountered an issue where after switching the UE off and then on again, the existing RRC connection is terminated and a new RRC connection is established each time. Below is the code snippet I’m using to simulate the switching off and on of the UE:

// in main.cc
// This runs when the RRC connection is successfully established
if (rrc_connection_established()) {
    // Switch off the UE
    ue.switch_off();

    // Switch on the UE
    ue.switch_on();
}

Each time the ue.switch_off() is called, followed by ue.switch_on(), the existing RRC connection gets terminated, and a new RRC connection is created. I would like to maintain the original RRC connection during this process.
