A method of a user equipment (UE) for establishing a session with one or more Stand-alone Non-Public Networks (SNPNs) includes first sending a service request to a SNPN network entity while the UE is in an idle mode, monitoring a response to the service request based on a first timer and a counter, initiating a second timer in response to determining that the counter exceeds a threshold count, receiving an indication of a change in a current SNPN, or an update associated with a selected entry of the current SNPN, stopping the second timer, and second sending the service request to the SNPN network entity for connection with a new SNPN, or the current SNPN with the update, the second sending being performed in response to determining that the second timer has stopped, and the second sending being performed while the UE remains in the idle mode.
