Terrestrial system and method for mitigating interference through inter-frequency offloading
Aspects herein for mitigating degraded communication quality experienced between a user device and a satellite due to overlapping radio frequency spectrum reuse by user devices communicating with terrestrial base stations via a telecommunications network. When the uplink quality is below a quality threshold, the telecommunications network identifies base stations with coverage areas that overlap with the coverage area of the satellite. The telecommunications network instructs and causes those base stations to adjust inter-frequency mobility thresholds for their uplink channels. Using an adjusted inter-frequency mobility threshold, user devices in communication with the terrestrial base stations are transferred to an uplink channel that does not overlap in the radio frequency spectrum used to communicate with the satellite. This mitigates degraded communication quality experienced between a user device and a satellite.
