A method for merging downlink multicast services in a cell

The invention discloses a method for realizing Cell Multimedia Broadcast (CMB) services downlink combination. The method transmits by downlink the identical streaming media services through a plurality of cells respectively, and the user end (UE) selectively combines and receives the downlink streaming media services from a plurality of cells. In this case, when the cell handover is conducted in the cell reselection, even if the services from the original dwelling cells of UE are interrupted, UE can also receive the streaming media services via other common frequency adjacent areas, the service interruption is avoided, the feelings of CMB service users are improved, and the service quality of the CMB service is enhanced; besides, because users receive the streaming media services from a plurality of cells by combining, the invention effectively improves the receiving quality of downlink data, thereby allows FACH channel carrying streaming media services to transmit by using smaller downlink transmission power, saves a mass of system resources and reduces interference on the network, with the saved network resources being used to open more CMB channels.
