Hi, I need to implement SGsAP before I go to a CSFB. I have one question about the configuration. I gonna create a configuration of mme.conf as shown below. mme: sgsap: addr: 127.0.0.2 tai: plmn_id: mcc: 001 mnc: 01 tac: 4130 lai: plmn_id: mcc: 001 mnc: 01 lac: 43690 However, if both TAC and LAC are alway the same PLMN_ID, the configuration can be changed as follows: mme: sgsap: addr: 127.0.0.2 plmn_id: mcc: 001 mnc: 01 tac: 4130 lac: 43690 I don't have enough knowledge about 2G/3G, so I hesitate in this part for a while. Perhaps, I will do it the first way. Do you have anybody to help? P.S. You can see the full configuration in this like: https://github.com/open5gs/nextepc/blob/master/support/config/nextepc.conf.i... Thanks a lot!

I would expect that the "primary" MCC/MNC are always the same for the MSC and MME of one particular network. There are many different strategies of broadcasting "equivalent" PLMNs, and for RAN sharing (MOCN, ...) but I believe that this doesn't affect the SGsAP interface. Please note I may be wrong, my experience with "multi PLMN" scenarios is rather limited.
