between  MSC  and  GCR

specified from  Rel-3
Source:   TS 23.002, clause 6a.1.1 

The GCR is the management data base for the voice group or broadcast calls in the area controlled by the associated MSC(s). Whenever the MSC needs data related to a requested voice group or broadcast call it interrogates the GCR to obtain the respective voice group or broadcast call attributes.

The protocol used to transfer the data over this interface is not standardized.
