    摘要: 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.

    摘要: According to the present invention, a random access method between a terminal and a base station comprises: a system information transmission step in which the base station transmits, to the terminal, system information including route values sequentially selected from among a set of routes; a random access preamble transmission step in which the terminal generates a random access preamble on the basis of the system information and transmits the generated random access preamble to the base station; a period setup step in which the base station sets a period available for an arrival of the random access preamble; and a random access preamble detection step in which the base station detects the random access preamble in said available period.
