MAP
Mobile Application Part
GSM/UMTS Mobile Application Part over TCAP for location update, authentication, SMS, and subscriber data management. Operation codes and ASN.1 structures dominate traces between HLR, VLR, MSC, and SMSC. Diameter and HTTP APIs replace many flows in LTE/5G cores, but MAP remains on interconnects.
