A radio network control method and a radio network controller are described. The radio network controller includes: a measurement control unit, adapted to receive radio network information sent by a network node, where the radio network information includes radio channel information and service serving information; a radio network information management unit, adapted to determine, according to the radio network information received by the measurement control unit, a radio network function that needs to be triggered and an algorithm corresponding to the radio network function, and encapsulate radio network information required by the algorithm into a radio network information combination for the algorithm; an algorithm management unit, adapted to determine an execution policy of the algorithm; and a procedure management unit, adapted to generate execution control signaling and send the execution control signaling to the network node.
