Hello,
IN CASE OF MOCN - Multi-Operator CORE NETWORK SHARING ........we will have multiple PLMN IDs in SIB1 and only 1cell identity as given below .
In this case, how can we conclude ECGI from SIB1 alone?
ie how can we conclude the cellidentity belongs to which PLMN ID (In this case 3 PLMN Ids)
Any help is highly appreciated.
Sample:
SEQUENCE BCCH-DL-SCH-Message {
CHOICE BCCH-DL-SCH-MessageType {
BCCH-DL-SCH-MessageType = c1 (0 dec, 0x0)
CHOICE BCCH-DL-SCH-MessageType_c1 {
BCCH-DL-SCH-MessageType_c1 = systemInformationBlockType1 (1 dec, 0x1)

MCC-MNC-Digit = x (0x0)
MCC-MNC-Digit = 1 (0x1)
MCC-MNC-Digit = x (0x2)
MCC-MNC-Digit = 0 (0x0)

MCC-MNC-Digit = z (0x3)
MCC-MNC-Digit = z (0x0)
}
cellReservedForOperatorUse = notReserved (1 dec, 0x1)
}
TrackingAreaCode = '1F12'H
