Abstract
When a server SV transfers a bootstrap message to a mobile communication terminal MS1, the bootstrap message is stored in a retry buffer of the mobile communication terminal MS1. Subsequently, when an IOTA feature is discontinued before a download start or in a download term, the IOTA feature is again executed based on the bootstrap message stored in the mobile communication terminal MS1 at a timing indicated by a retry timer.

A method of downloading system information on a mobile communication system to a mobile communication terminal for use in the mobile communication system, the system information being downloaded to the mobile communication terminal from a server via a computer network and mobile communication network, the method comprising:
- transmitting a boot message to the mobile communication terminal from the server;
- storing the boot message transmitted from the server in the mobile communication terminal;
- transmitting a download request of the system information to the server from the mobile communication terminal based on the boot message transmitted from the server;
- downloading the system information to the mobile communication terminal from the server based on the download request transmitted from the mobile communication terminal;
- detecting whether or not downloading the system information is failed;
- retransmitting the download request of the system information to the server from the mobile communication terminal based on the boot message stored, when downloading the system information is detected to be failed;
- and
- downloading the system information to the mobile communication terminal from the server based on the download request resent from the mobile communication terminal.
A mobile communication terminal for use in a mobile communication system including a feature for downloading system information on the mobile communication system to the mobile communication terminal from a server via a computer network and mobile communication network, the mobile communication terminal comprising:
- a reception part configured to receive a boot message sent by the server;
- a storing part configured to store the boot message received by the reception part;
- a first reception control part configured to transmit a download request of the system information to the server based on the boot message received by the reception part, and receive the system information downloaded from the server based on the download request;
- a first detecting part configured to detect whether or not downloading of the system information is failed by the first reception control part;
- and
- a second reception control part configured to resend the download request of the system information to the server based on the boot message stored in the storing part, when the first detecting part detects the downloading of the system information to be failed, and receive the system information downloaded from the server based on the download request retransmitted.
