Output of Y.MMCF from January 2009 meeting
Issues to be solved after January meeting
Functional Entities and interfaces are to be identified;
Interaction between NACF and MMCF is for further discussion
Interaction between MMCF and RACF needs the joint discussion with SG13Q4 experts and needs further contributions

Outcomes of Interim meeting (concluded)
0903-TD-7 Proposal for the functional entities of Y.MMCF
Mobility Location Management Functional Entity (MLM-FE) agreed Network Information Repository Functional Entity (NIR-FE) agreed Continuing discussion (at time of writing) on how finely to divide
the remaining functions of network information distribution, handover decision, and handover control.
Need a sufficiently refined model that mapping between it and 3GPP entities (e.g. ANDSF) is possible.
Basic underlying issue is what the linkages there are amongst the FEs and between them and the UE. Would like to limit the number of interfaces supported by the UE (e.g. to MLM-FE and one other FE).

Figures from the Interim meeting
Whether there is a separate Network Information Distribution Functional Entity (NID-FE) is to be further discussed in May meeting as well as the interface between UE and NID-FE.

Y.MMCF is scheduled for approval in May meeting;
The mapping with 3GPP should be identified in the Y.MMCF document before approval.
Thank You!
