    摘要： The present invention is directed to a method of changing a transmission mode, a method of requesting a packet retransmission, and a method of retransmitting a packet with respect to a broadcasting or multicast service. According to the invention, a plurality of terminals provided with one broadcasting or multicast service shares one random access channel (RACH) so as to transmit channel information. Accordingly, a base station receives the channel information through one RACH from the terminal or detects a packet collision generated in the RACH to confirm a request for changing the transmission mode or a request for maintaining the transmission mode by the terminal.

    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.

    摘要： In a satellite communication system having a long round-trip delay time, a user terminal reports initial buffer status information when the communication between the satellite and the use terminal started. When a trigger, a timer or padding requiring buffer status information report is generated, the user terminal checks whether there are data to be re-transmitted due to transmission failure from the previous BSR. When transmission-failed data exists, the user terminal sets buffer status amount, which is reported through BSR, as a value that is obtained by adding the amount of transmission-failed data to the amount of newly added after previous report. When there are no transmission-failed data, the user terminal reports BSR which is set as the amount of newly added data to the buffer after previous report. For discriminating entire buffer status reporting and the increased amount of data reporting, the reserved index of a header file is used.

    摘要： Provided are a mobile communication system and a cell reselection method of a mobile communication terminal. The mobile communication system includes two or more communication systems using different transmission modes and a mobile communication terminal connectable to the two or more communication systems. The mobile communication terminal measures received signal strength of a satellite communication cell when being switched to an idle mode, divides priority of a satellite communication system using the measured received signal strength and location information of the mobile communication terminal, and sets a first threshold value necessary for cell reselection of the satellite communication system.
