Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] figure 1 A schematic diagram of a provision device for providing system information broadcast SIB12 by an eNB according to one aspect of the present invention is shown; Specifically, the first scheduling obtaining means 11 assigns a separate system information message to SIB12 according to the configuration information of the cell to which the eNB belongs, so as to obtain the SIB12 scheduling information corresponding to SIB12, wherein the SIB12 scheduling information is included in the corresponding SIB1; An encoding device 12 encodes the SIB1 including the SIB12 scheduling information to obtain an encoded SIB1; the first sending means 13 sends the encoded SIB1 and the system information message corresponding to the SIB12 to the eNB corresponding terminal equipment. Here, the providing device includes, but is not limited to, a network device, or a d...

Abstract

The purpose of the invention is to provide a method and device for providing a system information block type12 (SIB12) by an eNB. The method comprises: a provider device distributing an individual system information message to the SIB12 so as to obtain SIB12 scheduling information corresponding to the SIB12, the SIB12 scheduling information being included in a corresponding SIB1; performing coding processing on the SIB1 comprising the SIB12 scheduling information so as to obtain a coded SIB1; and sending the coded SIB1 and the system information message corresponding to the SIB12 to a terminal device corresponding to the eNB. Compared to the prior art, the SIB12 is individually packaged in the system information message so as to be sent to the terminal device so that the system information message for the SIB12 is simpler and can be individually processed without comprising other SIBs, thus the implementation mode of processing the SIB12 by the eNB is simplified, the coding and broadcasting of the system information message are more efficient, and the scheduling of the system information message is 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 a protocol data unit PDU (Protocol Data Unit) of the radio resource control protocol RRC (Radio Resource Control) —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 essen...
