Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may evaluate a first and second utility value for a first and second subscriber identity module (SIM) associated with a first and second service subscription respectively for each zone of a set of zones along a route of the UE. The first utility value and the second utility value may be based on a throughput level and a network load of the service subscriptions for each zone of the set of zones that includes zones that the UE is predicted to travel through. Therefore, the UE compares the first utility value to the second utility value to determine a service subscription switch condition for each zone for the UE to switch between the SIMs of the UE based on a function of the service subscription switch conditions for the set of zones.

Abstract: A V2X event-message dictionary and a binning function are received from a cloud server. Sensor data is compared to events specified in the V2X event-message dictionary to identify a best-fit event for the sensor data. A number of bins and a bin number for the event are computed using the binning function. A V2X message is transmitted including the number of bins and the bin number, thereby avoiding including the sensor data in the V2X message.
