    Abstract: A system for 5G MICO mode operation of a vehicle during an ignition off mode includes a telematics unit and a telematics communication mode controller. The controller monitors energy consumption by the telematics unit and estimates a total energy consumption of the telematics unit through a time period. The controller further compares the total energy consumption to a first threshold energy consumption and a second threshold energy consumption and, when the total energy consumption is less than the first threshold energy consumption, operates the telematics unit in a first mode including unrestricted communication. The telematics communication mode controller, when the total energy consumption is between the first threshold energy consumption and the second threshold energy consumption, operates the telematics unit in a second MICO mode and, when the total energy consumption is greater than the second threshold energy consumption, deactivates communications by the telematics unit.

    Abstract: A method of selecting primary and secondary cellular networks for a vehicle comprises measuring cellular connectivity parameters for cellular communication between a first subscriber identity module (SIM) and a first cellular network and for cellular communication between a second SIM and a second cellular network, comparing measured cellular connectivity parameters for the first SIM to measured cellular connectivity parameters for the second SIM, designating one of the first SIM and the first cellular network and the second SIM and the second cellular network as a primary network, and designating the other one of the first SIM and the first cellular network and the second SIM and the second cellular network as a secondary network, measuring cellular connectivity parameters for the primary and secondary networks, comparing the measured cellular connectivity parameters for the primary and secondary networks, switching designation of the primary and secondary network based on measured cellular connectivity parameters.

    Abstract: A method of prioritizing updates to vehicles includes receiving one or more update requests for a first vehicle; determining a receiving capacity of the first vehicle; checking status of a battery and communications of the first vehicle; prioritizing the one or more update requests based on the receiving capacity of the first vehicle; and sending the prioritized update requests to the first vehicle. The method may include receiving one or more update requests for an additional vehicle; determining a receiving capacity of the additional vehicle; prioritizing the one or more update requests based on the receiving capacity of the additional vehicle; sending the prioritized update requests to the additional vehicle: and determining whether the vehicles are part of a common location group. Creating profiles from sets of communications available for the vehicle and selecting the best connection speed from profiles. Updating radio maps based on connection speeds.

    Abstract: A method for operating a mobile telecommunications device connected to a first mobile telecommunications network having a country code identifying a first country includes determining whether the mobile telecommunications device crosses from the first country into a second country. The method also includes, if the mobile telecommunications device crosses from the first country into the second country, scanning, through the mobile telecommunications device, for mobile telecommunications networks discoverable to the mobile communications device, where each discoverable mobile telecommunications network has a country code identifying a service country of that mobile telecommunications network. Additionally, the method includes offering to a user of the mobile telecommunications device to manually connect the mobile telecommunications device to the discoverable mobile telecommunications networks in order of priority on a prioritized roaming list associated with the mobile telecommunications device and having a country code not identifying the first country.

    Abstract: A system for managing communication between a vehicle and a broker module includes a telematics unit connected to the vehicle. The telematics unit is configured to carry out wireless data communications according to a publish-subscribe messaging protocol. A command unit is in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The telematics unit is configured to establish a network connection with the broker module. The command unit is adapted to create a dynamic retry delay process for the network connection by varying a connection retry delay time based on a plurality of failure categories and an operation mode of the vehicle. The plurality of failure categories each corresponds to a respective failure in the network connection.
