Problems solved by technology

[0006] However, if the terminal always decodes and updates the system information when the system information is not changed, the power of the terminal will be unnecessarily consumed
Specifically, if a terminal in sleep mode or idle mode decodes and updates system information transmitted through SFH and broadcast messages even when the system information is not changed, it is inefficient in terms of power consumption of the terminal

Abstract

The present invention relates to a method and an apparatus for updating additional broadcast information transferred through a broadcast message. The method for updating the additional broadcast information (ABI) of a broadband wireless connection system that transmits and receives data through a superframe that includes a superframe frame header (SFH) comprises the steps of: receiving from a base station at least one kind of ABI and ABI configuration information that includes ABI transmission information and ABI change information through the superframe; comparing the pre-stored ABI change information with the received ABI change information to judge whether or not the ABI is changed; and decoding and updating the changed ABI in consideration of the ABI transmission information or the ABI change information if the results of the judgment indicate that the ABI is changed.

Description

technical field [0001] The present invention relates to updating system information in a broadband wireless communication system, and more particularly, to a method and apparatus for updating Additional Broadcast Information (ABI) transmitted through additional broadcast messages. Background technique [0002] For communication between a base station and a terminal in a broadband wireless communication system, system information necessary for communication must be transmitted from the base station to the terminal. A base station may transmit essential system information necessary for the base station to communicate with a terminal through a superframe header (SFH), and transmit additional, necessary system information through an independent broadcast message. [0003] Additional broadcast information (hereinafter referred to as ABI) necessary for communication between the base station and the terminal may include extended system parameters, system configuration information, ...
