It led to the collaboration between 3GPP and Broadband Forum to officially publish it as BBF Data Model called TR-196.
In order to avoid the fragmentation in the market, Femto Forum initially focused on these areas.
As the Forum reached consensus, the leading companies brought the joint proposal to 3GPP to standardize the HNB architecture.
It includes the specification of signalling protocol Home Node B Application Part (HNBAP) and RANAP User Adaptation (RUA).
It resulted in the WI "UTRA HNB: 3G Home NodeB OAM&P Type 1 Management Interface."
During the specification work, it was decided that the Data Model itself is to be owned and published by the Broadband Forum (BBF) rather than 3GPP SA5 to have the ownership of it.
After the completion of 3GPP Release 8, a group of companies proposed a new WI "Enhanced Home NodeB / eNodeB: 3G HNB and LTE HeNB OAM&P Type 1 Interface" to define Data Model for LTE Home eNode B.
At the same time, 3GPP2 established similar collaboration framework with BBF to standardize the CDMA2000 FAP Data Model.
This includes extracting commonly used objects and parameters, and aligning other existing BBF Data Models.
This resulted in moving some parts of the objects / parameters in original Issue 1 to another BBF Data Model, creating a separate Data Model specification, and re-organizing some of the existing object / parameter structure and definition.
