摘要：
Apparatus and Method for transmitting control message related to a packet call service in an IP multimedia subsystem (IMS) that transmits/receives an IMS control message using a control plane to reduce a delay caused by setting of a user plane in a packet call setup process. A user equipment (UE) determines whether an IMS service is registered in response to a radio resource control (RRC) connection request. The UE sets an SRB_IMS request parameter requiring that the IMS control message be processed through a signaling radio bearer (SRB) depending on whether the IMS service is registered. The UE transmits an RRC connection request message including the SRB_IMS request parameter to a radio network controller (RNC). The UE configures an SRB_IMS entity.
