System information processing method and apparatus, and communications system
First Claim
1. A system information processing method comprising:
- receiving a first synchronization signal; and
identifying whether configuration information of the first synchronization signal is configured as an indication for a system information change; and
if it is identified that the configuration information of the first synchronization signal is configured as the indication for a system information change, receiving broadcast system information, and updating a mapping relationship between a current synchronization signal and the system information according to the first synchronization signal and the received broadcast system information.

Abstract
Embodiments of the present invention provide a system information processing method. The method in the present invention includes: receiving a first synchronization signal; and identifying whether configuration information of the first synchronization signal is configured as an indication for a system information change; and if it is identified that the configuration information of the first synchronization signal is configured as the indication for a system information change, receiving broadcast system information; and updating a mapping relationship between a current synchronization signal and the system information according to the first synchronization signal and the received broadcast system information. The embodiments of the present invention may effectively reduce power consumption of UE and implement that the UE may quickly learn that the system information changes in a case of low power consumption.
