FIELD: information technologies.
SUBSTANCE: radio network controller (SRNC) decides, whether to adjust current channels E-AGCH (absolute permission of improved dedicated channel) and E-RGCH/HICH (relative permission of improved dedicated channel/indicator of confirmation of hybrid automatic request for repeated transfer of improved dedicated channel) in compliance with "Code Variation Indicator" E-AGCH and "Code Variation Indicator" E-RGCH/HICH, added into system of interface signals Iur. SRNC controller decides, whether DRNC controller is to be authorized to adjust current channels E-AGCH and E-AGCH/HICH in compliance with "Permission for Code Variation" E-AGCH and "Permission for Code Variation" E-RGCH/HICH, added into system of interface signals Iur.
EFFECT: elimination of technical problem, which is impossibility to control result of re-assignment of channels of absolute permission of improved dedicated channel or relative permission of improved dedicated channel-indicator of confirmation of hybrid automatic request for repeated transfer of improved dedicated channel by controller of radio network after movement of mobile communication device from cell controlled by SRNC controller, into cell controlled by radio network controller with frequency drift.
