<p>In order to define a new signal between C-plane and T-plane and obtain Dift RNC capable of physically separating the two planes, a new signal (300) is defined and introduced between C-plane (31) and T-plane (32) in Drift RNC (30). The new signal (300) is a binding ID acquisition request/response signal and a transmission path control success report signal. Thus, since the signal (300) is provided between C and T-plane for acquiring Binding ID, it is possible to acquire the Binding ID without transmitting a transmission path signal. Moreover, since a new signal is provided for reporting from the T-plane to the C-plane that transmission path control between the Node B, Drift RNC, and Serving RNC is complete, the C-plane can recognize that an associated process is complete. Consequently, even if the C/T-planes are physically separated from each other, they can operate as a Drift RNC without contradiction.</p> |
