description The disclosed technology proposes a new methodology to include the effect of speed and direction of a UE into the threshold used for determining when to switch between a 4G UL connection and a 5G UL connection. The system can use a lookup table with various speeds mapping to varying thresholds. The system can use an accelerometer sensor or digital compass to determine the direction of the vehicle, such as heading away from or toward the 5G site, so the vehicle can switch sooner from 5G-NR to LTE and from LTE to NR, respectively. For C-V2X applications, latency is an important factor because 5G technology provides shorter latency than 4G; thus keeping the link on 5G is preferred when under good coverage. Further, the idea is not limited to UL, 5G and/or vehicle technologies, but can also be applied to DL direction, Wi-Fi and/or drone technologies as well.
