Let's understand the SIP messages through the drive test layer 3 messages. We have seen so far how the user can attach, how the default radio bearer or the EPS bearer that is being established. And then here we are talking about the different SIP messages. we understand there are SIP message 1, which is actually containing the MCC, MNC, and the cell IDs in that case, also contain the periodicity of the other SIP messages. Now, if we go back to the drive test in that case, and we just understand, so the SIP message which is here, the SIP message 1, what it contains, it contains various information related to the PLMN identity, related to the country code, network code of the network, and then it contains the cell ID, then it contains either the cell is barred or not, and it contains certain other information related to the minimum signal strength which is required to access to the network. Here it is every time multiplied with two, so QRX level min in a way it's neck 130 dBm that is…
