Abstract: Techniques are directed toward network identification collision detection. An example method includes selecting a first subscriber identity module (SIM) associated with a public land mobile network identifier (PLMN ID) and a network identifier (NID) of a private network. The method can further include generating a first non-access stratum (NAS) registration request to establish a connection with the private network using the first SIM. The method can further include processing a NAS registration request reject message received from the private network. The method can further include selecting a second SIM associated with the PLMN ID and the NID. The method can further include generating a second NAS registration request to establish a connection with the private network using the second SIM. The method can further include processing a NAS registration request success message received from the private network. The method can further include logging NID collision information.

Abstract: Methods, devices, and systems for establishing a geofence for a Non-Public Network (NPN) using an Embedded Subscriber Identity Module (eSIM) associated with the NPN. The method includes receiving, by a receiver of a User Equipment (UE), an eSIM associated with an NPN, where the eSIM includes geofencing data. The UE performs wireless communication using the NPN when the UE is within an area defined by the geofencing data.

Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.
