NETWORK AWARENESS OF MULTI-UNIVERSAL SUBSCRIBER IDENTITY MODULE (MUSIM) DEVICES BY ASSISTANCE INFORMATION SIGNALING

Systems, methods, and devices include techniques for improving network resource usage for a multi-universal subscriber identity module (MUSIM) device in a multi-network environment. A wireless device can send to a network function of a network (e.g., an Access and Mobility Management Function (AMF) or a Mobility Management Entity (MME) an indication that the wireless device is a MUSIM device. The indication can be included in a UE capability information message of an attach procedure and/or a UE assistance information message of a UE assistance information capability procedure, as defined by 3GPP standards. Upon sending the indication, the wireless device can receive a response message indicating that the network supports various MUSIM features of the MUSIM device. The wireless device can receive a paging offset request from the network function. Accordingly, the wireless device can change a device parameter associated with the network (e.g., a paging offset value).
