  • Publication number: 20210282064
    Abstract: In wireless communication systems and methods for high-speed mobility deployments, a mobility status of a communication device can be determined. For example, the speed at which the communication device is traveling can be determined (e.g. such as communication devices traveling on a high-speed transportation (HST) system). HST networks can be prioritized based on the determined mobility status of the communication device when performing a fallback communication and/or when returning from the fallback communication.
