Problems solved by technology

[0004] With the increase of new features introduced into the system, the length of the system information also increases. The UE needs to read all the system information before initiating RACH access before initiating access. Therefore, it takes longer for the UE to read the system information before initiating RACH access. time; although the length of the system information is reduced through compression, the traditional UE cannot recognize the compressed cells, and there is an incompatibility problem, resulting in the traditional UE being unable to obtain the system broadcast information and unable to access the new cell. talk phenomenon

Abstract

Disclosed are a method, device and system for broadcasting and receiving system information, belonging to the communication field. The method for broadcasting system information includes: dividing cell lists with identical properties in a system information block into at least two groups (101); broadcasting information about each cell list so that user equipment can access randomly according to the information read about at least one group of cell lists (102). The system includes: a network side device and user equipment. The present invention shortens the time for the user equipment to read system information by way of dividing the cell lists with identical properties in a system information block into groups and broadcasting the information about each group of cell lists so that the user equipment can access randomly after reading the information about one group of cell lists. In addition, no incompatibility problem exists in the present invention since compression is not involved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for broadcasting and receiving system information. Background technique [0002] In the communication field, in order to establish communication with the network, UE (User Equipment, user equipment) needs to send a message to the network through RACH (Random Access Channel, random access channel) to apply for a signaling channel. Before the UE initiates RACH access to the network, the network needs to send the system information required by the UE when initiating RACH access to the UE. The system information is included in multiple SIBs (System Information Blocks, system information blocks). One SIB is a combination of a series of system information with the same attribute, and the network sends the system information to the UE in the form of broadcast. [0003] When broadcasting system information, the system information is divided into different se...
