Abstract: Systems, methods, and devices include techniques for establishing an enhanced multi-access protocol data unit (PDU) session in a multi-network environment. Various registration procedures may be used to allocate resources between a first network (e.g., a Mobile Network Operator (MNO) and a second network (e.g., a Mobile Virtual Network Operator (MVNO). For instance, a method includes sending by a wireless device to a network, indication(s) related to network capabilities of the wireless device. The indication(s) include whether the wireless device supports a multi-access PDU session comprising a first PDU session and a second PDU session. The first PDU session is established via a 3rd Generation Partnership Project (3GPP) access the second PDU session is established via a first non-3GPP. The indication(s) include whether the wireless device supports an enhanced multi-access PDU session comprising a third PDU session, wherein the third PDU session is established via a second non-3GPP access.

Abstract: A notification server is provided for a multi-network wireless communication system. The notification server includes a processor and a memory having computer executable instructions stored therein. The instructions, when executed by the processor, cause the processor to receive first device information from a mobile communication device wirelessly connected to a macro cell network of the multi-network wireless communication system. The instructions further cause the processor to determine, based on the received first device information, that a small cell network of the multi-network wireless communication system is available for communication with the mobile communication device. The instructions further cause the processor to transmit a notification to the mobile communication device to search for the small cell network for transition thereto.
