Channel configuration method and system

The present invention provides a channel configuration method, comprising the steps of: a first step, the user device sends a first message to the radio network controller, wherein the first message contains information indicating the type of a voice call, and carries a non-access stratum information; a second step of, in response to the first message, the radio network controller transmits a second message to the core network, wherein the second message contains a non-access stratum information; a third step, the radio network controller indicating a voice call according to the type of the user equipment transmits the third message information, wherein the third message containing the channel configuration information; and a fourth step of, in response to the third message, the user equipment according to the channel configuration information to configure a dedicated transport channel and a dedicated physical channel. Through the above technical solution to achieve the following technical effects: reducing the time UE call setup, while reducing the complexity of the system, thereby avoiding the waste of radio resources.
