FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communication. A method is proposed for transmitting radio channel (RB) configurations from a source base station conforming to the new fifth generation (5G) radio communication (NR) standard to a target base station conforming to Evolved Universal Terrestrial Radio Access (E-UTRA). The 5G NR base station determines the need to handover the user equipment to the base station corresponding to Evolved Universal Terrestrial Radio Access (E-UTRA), and sends a handover request message for the user equipment to the E-UTRA base station, including the radio bearer configuration for transmitting protocol units of data between the source 5G NR base station and the subscriber unit.
EFFECT: ensuring handover of the UE without allowing service interruption due to RB change.
