PURPOSE: A method for transmitting a control signal in a mobile communication packet network is provided to control a user date by setting up a virtual channel for a control signal between transmitting nodes in the mobile communication packet network. CONSTITUTION: PPP data link between nodes is set up between PPP-UTE(PPP User Terminal Entity)(200) and PPP-NTE(PPP Network Terminal Entity)(205). A virtual line for transmitting a user date is comprised of PPP-NRE(PPP Network Relay Entity)(201-204). The PPP-UTE(200) and PP-NTE(205) are an entity(that is, a node) which transmits/receives and processes the user data and the PPP-NRE(201-204) is an entity transmitting the user data. When a relay protocol A is used in the PPP-UTE, A node connected to the PPP-UTE performs a communication by using the relay protocol and if a relay protocol B is used in B node connected to the A node, a communication between the A node and the B node is performed by using a relay protocol B. Therefore, a stable and reliable data communication service is provided as the user data communicated between the nodes can be controlled. |
