Abstract

The object of the present invention is to provide a method and device for providing system information broadcast SIB12 by eNB. The provisioning device allocates a separate system information message for SIB12 to obtain SIB12 scheduling information corresponding to SIB12, wherein the SIB12 scheduling information is included in the corresponding SIB1; encodes the SIB1 including the SIB12 scheduling information to obtain the SIB12 scheduling information. Encoding SIB1; sending the system information message corresponding to the encoded SIB1 and SIB12 to the terminal equipment corresponding to the eNB. Compared with the prior art, the present invention separately encapsulates SIB12 into a system information message to send to the terminal device; makes the system information message for SIB12 simpler, and can be processed separately without including other SIBs, This simplifies the implementation of the eNB processing the SIB12, making the encoding and broadcasting of system information messages more efficient, and the scheduling of system information messages more flexible.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to a technology for providing system information broadcast SIB12 by eNB. Background technique

[0002] According to the 3GPP standard (TS36.331), the CMAS (Commercial Mobile Alert System) service is broadcast to terminals or user equipment in SIB12 format (System Information Block Type 12). At the same time, as defined in relevant standards, optionally, SIB12 can be encapsulated together with other possible system information block SIBs in the protocol data unit PDU (ProtocolData Unit) of the radio resource control protocol RRC (Radio Resource Control)β€” β€”To generate system information SI (System Information), and finally all SI messages are encapsulated into abstract syntax notation ASN.1 (Abstract Syntax Notation One) data, and transmitted to the user equipment through radio bearers. Although 3GPP has described how to encapsulate SIB12 as a part of SI messages, in ess...
