Abstract

The invention provides a system information broadcasting method, device and base station. The method includes: periodically broadcasting a set of basic system information blocks, wherein the set of basic system information blocks includes broadcast parameters of basic system information blocks and non-basic system information block sets, and the basic system information blocks include user equipment and Parameters necessary for establishing a network connection, the non-basic system information block set is a system information block other than the basic system information block; receiving a non-basic system information block set broadcast request sent by the user equipment; according to the basic system information block set includes broadcast parameters of the non-basic system information block set, and broadcast the non-basic system information block set. The present invention can save air interface resources and avoid interference to neighboring cells caused by continuous broadcasting on the air interface.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a system information broadcasting method, device and base station. Background technique [0002] System information broadcast is an important function in the communication system. The base station broadcasts the main information of the access network system to the UE (User Equipment, user equipment) through the broadcast channel, so that the UE can establish a wireless connection based on this information and complete various wireless communication functions. . The system information is sent on the broadcast channel in the form of a system information block, and different system information is included in different system information blocks. [0003] The system information broadcast is usually transmitted on the air interface, and all UEs residing in the cell can receive the system information broadcast by the base station. When the base station broadcast...
