- Abstract
- Disclosed is a communication method of a satellite mobile communication system. The communication method of a satellite mobile communication system, includes: receiving system information indicating frame intervals in which first user equipments using a satellite radio interface in commonality with a terrestrial radio interface do not perform communications from a base station; accessing the base station in the rest frame intervals other than frame intervals in which the first user equipments do not perform communications, based on the system information; transmitting the system information from the base station to second user equipments using a satellite radio interface optimized for satellite environment; and accessing the base station in the rest frame intervals based on the system information received in the second user equipments.
