The present invention relates to a method for a channel to reselect signaling in a cellular telecommunication network. And the present invention is characterized in that the method comprise the following steps: signaling that contains a connection-building request is received from a mobile station; the congestion condition in a district is informed; then in the district, the connection building that is requested by the mobile station needs the refusal of the connection-building request; and connection refusal information is generated in the cellular telecommunication network and indicates theinformation to the mobile station, which is about at least reference value that is used in the trial of novel connection building and is associated with the connection building; the connection refusal information is used as the signaling that is reselected by the channel and is transmitted to the mobile station from the cellular telecommunication network.
