Method and apparatus for updating system information in broadband wireless communication system
First Claim
1. A method for updating system information in a terminal in which data is transmitted via superframes, the method comprising:
- receiving scheduling periodicity information of the system information and change information indicating a change in content of the system information, the received change information transmitted via a superframe header (SFH), the SFH comprising a primary SFH (P-SFH) including the change information and a secondary SFH (S-SFH) including at least one subpacket containing the system information, the received scheduling periodicity information indicating a transmission periodicity of the at least one subpacket;
updating the system information based on the received change information; and
waking up the terminal until the terminal receives information related to the updated system information when the terminal detects that the system information is not the updated system information.

Abstract
A method for updating system information in a terminal in which data is transmitted by means of superframes, includes: receiving system information, scheduling periodicity information of the system information and changing information indicating changing status of the system information transmitted by means of a superframe header (SFH) from a base station; and updating the system information based on the changing information, wherein the SFH comprises a primary SFH including the changing information and a secondary SFH including at least one subpacket containing the system information, the scheduling periodicity information indicating a transmission periodicity of the subpacket is transmitted by means of the primary SFH or a predetermined subpacket, and when the terminal detects that a changed system information transmitted by means of the subpacket is not scheduled as indicated in the scheduling periodicity information, the terminal wakes up until the changed system information is received.
