A channel type switching method for Multimedia Broadcast and Multicast Service (MBMS) point-to-point (P-t-P) channel and point-to-multi point (P-t-M) channel is provided. When a user equipment (UE) moves to a cell in a drift radio network controller (DRNC) with an Iur interface, the DRNC decides to switch between a common channel and a dedicated channel and then notifies a serving radio network controller (SRNC) of MBMS channel type and common channel parameters.
