AI summary

A data communication system selects an original wireless network slice for a wireless communication device. The data communication system identifies one or more radio signal parameters for the original wireless network slice. The data communication system determines one or more radio signal levels for the wireless communication device. The data communication system selects a different wireless network slice for the wireless communication device in response to the one or more radio signal parameters for the original wireless network slice and the one or more radio signal levels for the wireless communication device.
