The bearer change control entity is adapted to determine and control conversion from a multicast bearer mode to a unicast bearer mode or conversion from the unicast bearer mode to the multicast bearer mode according to the received bearer change notice. Further, a method for controlling bearer change is also provided. The system, the device, and the method are capable of sensing changes in multicast capability and user will and establishing the unicast/multicast bearer mode for data transmission
