Embodiment Construction

[0030]When the UE needs the on-demand system information, it first checks whether the scheduling information of the on-demand system information in the current MSI indicates whether the on-demand system information required by the UE is being broadcast. If the MSI indicates that the on-demand system information has not been broadcast, send the request message for the on-demand system information to the base station, and after sending the request message for the on-demand system information, you can monitor the on-demand system information within the scheduling period SI window to obtain the required on-demand system information. After the base station receives the on-demand system information request message sent by the UE, if the network decides to broadcast the requested on-demand system information, according to the principle of LTE, the system information update can only be performed at the boundary of the next modification period, and the base station will update the syste...

Abstract

The invention relates to a method and device for scheduling on-demand system information and a base station. The method comprises the steps of immediately updating scheduling information of on-demandsystem information in minimum system information within the current modification period when receiving a request message sent by UE (User Equipment) for the on-demand system information and deciding to broadcast the on-demand system information so as to indicate that the on-demand system information is about to be broadcast, wherein the on-demand system information is non-minimum system information required by the UE; and broadcasting the updated minimum system information within the next minimum system information scheduling period in the current modification period. The scheme can avoid unnecessary signaling overhead, reduce the power consumption of the system and save processing resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a scheduling method, device and base station for on-demand system information. Background technique [0002] In recent years, the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP) and Long Term Evolution (Long Term Evolution, LTE) technologies have developed rapidly and have been widely applied in various technical fields. In LTE, system information is divided into a master information block (Master Information Block, MIB) and multiple system information blocks (System Information Block, SIB). Wherein, MIB is transmitted by MIB message, SIB1 is transmitted by SIB1 message, and other system information blocks SIBs except SIB1 are transmitted by system information (System Information, SI) message. One or more SIBs other than SIB1 have the same scheduling requirement, that is, other SIBs with the same transmission cycle can be transmit...
