Mobility in a Multi-Network Wireless System

A system configured for wireless communication, the system comprising:

• a first network in communication with an external network;
• a second network in communication with the external network;
• and
• a user device configured for dual connectivity to the first network and the second network, the user device communicating with the external network when connected to the first network or the second network, the user device comprising data processing hardware and memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• receiving one or more data packets from the external network when the user device connects to the first network;
• transmitting a measurement configuration to a modem of the user device;
• receiving a measurement report from the modem, the measurement report based on the transmitted measurement configuration;
• determining whether it is feasible for the modem to perform a network switch to connect the user device to the second network based on the received measurement report;
• and
• when it is feasible for the modem to perform the network change, transmitting a network change command to the modem, the network change command causing the modem to perform the network switch to connect the user device to the second network.
