FIELD: communications engineering. SUBSTANCE: proposed method for recovering data groups between communication systems incorporating one first mobile-object communication system, one second mobile-object communication system, and mobile stations includes transfer of request for recovering data groups, generation of one or more virtual connection requests for first database of mentioned group by means of second mobile-object communication system, transfer of virtual connection request to first database of first mobile-object communication system by means of second mobile-object communication system, and correction of data groups in first database in response to first request for virtual connection. EFFECT: provision for supporting data groups in first and second databases of first and second mobile-object communication systems, respectively. 14 cl, 3 dwg
