This document specifies a mapping between TMF OTrP Profile messages and TMF ASN.1 commands. The document specifies how OTrP request messages received by a TEE is mapped to TMF ASN.1 commands and the TMF ASN.1 response output to OTrP response messages. The mapping is not essential to perform directly – that is, it is not required to convert incoming request messages from OTrP Profile to TMF ASN.1, but this is a possible realization where appropriate. It is mandatory that the execution of an OTrP request message provides the same result as the equivalent shown TMF ASN.1 Profile command would have achieved. The OTrP Security Domain, message representation and associated security mechanisms can be found in [OTrP Profile].
