For an area-specific SIB, a first terminal compares a required SIB with a SIB list of a second terminal, compares an SI area identifier corresponding to the required SIB with an SI area identifier of the second terminal, and compares a tag value corresponding to the required SIB with the SIB list of the second terminal; if the SIB list contains the SIB consistent with the required SIB, the SI area identifier consistent with the SI area identifier corresponding to the required SIB in the area identifier of the SI of the second terminal, and the SIB list contains the tag value consistent with the tag value corresponding to the required SIB, the required SIB is matched with the SIB indicated by the first message;

for an area-specific SIB, if the first message further includes a PLMN identifier, the first terminal compares a required SIB with a SIB list of the second terminal, compares an SI area identifier corresponding to the required SIB with an SI area identifier of the second terminal, compares a tag value corresponding to the required SIB with a SIB list of the second terminal, and compares a PLMN identifier corresponding to the required SIB with a PLMN identifier list of the second terminal; if the SIB list contains the SIB consistent with the required SIB and the SI area identifier consistent with the SI area identifier corresponding to the required SIB in the area identifiers of the SIs of the second terminal, the SIB list contains the tag value consistent with the tag value corresponding to the required SIB, and the PLMN identifier consistent with the PLMN identifier corresponding to the required SIB is contained in the PLMN identifier list, the required SIB is matched with the SIB indicated by the first message.

a direct communication link is established with the first terminal;

Alternatively, in the case where there is one target terminal that has established a direct communication link with the first terminal among a plurality of second terminals capable of providing the desired SI and/or SIB, the target terminal may be directly regarded as the fourth terminal;

in the case that there are a plurality of target terminals that have established direct communication links with the first terminal among a plurality of second terminals capable of providing the desired SI and/or SIB, a target terminal among the target terminals having a signal quality higher than a signal quality threshold value with the first terminal may be regarded as the fourth terminal;

in the case that there are a plurality of target terminals that have established direct communication links with the first terminal among a plurality of second terminals capable of providing the desired SI and/or SIB, a target terminal having the highest signal quality with respect to the first terminal among the target terminals may be regarded as the fourth terminal;

Selecting a target terminal with signal quality higher than a signal quality threshold value between the target terminal and the first terminal from the second terminals capable of providing the needed SI and/or SIB as the fourth terminal;

selecting a target terminal with highest signal quality between the target terminal and the first terminal from the second terminals capable of providing the needed SI and/or SIB as the fourth terminal;

and randomly selecting one terminal from the second terminals capable of providing the needed SI and/or SIB as the fourth terminal.

According to the transmission processing method of the system message, through screening of the fourth terminal, signaling overhead between the first terminal and the fourth terminal can be saved, and the fourth terminal with higher signal quality can be selected, so that transmission efficiency of the system message is improved.

Optionally, the first terminal sends a third message to a fourth terminal, including:

Optionally, after determining the fourth terminal, if the fourth terminal has established a direct communication link with the first terminal, sending the third message to the fourth terminal through a direct communication link unicast connection;
