Abstract
On a first network element in a radio access network (RAN), supporting operations, management and administration (OAM) between network elements that support Ethernet in the first mile (EFM) and network elements that support connectivity fault management (CFM) in the radio access network by receiving an EFM message from a second network element that supports EFM, wherein the second network element is in the RAN and wherein the EFM message includes OAM data; converting the OAM data from the EFM message into a sub-type-length-value (sub-TLV) of a CFM message; and transmitting the CFM message including the OAM data in the sub-TLV to a third network element that supports CFM, wherein the third network element is in the RAN, whereby an end-to-end OAM sublayer is provided in the RAN by conversion of OAM data from EFM to CFM.
