The invention discloses a backup method for time-division synchronous CDMA multimedia broadcast multicast TD SCDMA MBMS business, RNC will be divided with a wireless network controller MBMS business is dominated by SRNC, SRNC and DRNC alternate with SRNC and SRNC, the main reserve were established with the core network Iu and MBMS bearing distribution business the related resources, the main SRNC through the Iur interface to establish MBMS synchronous data transmission with DRNC Iur and MBMS bearing distribution business related resources and, when informed of the main standby SRNC fault with SRNC, through the Iur interface and DRNC Iur carrier synchronization establishment and distribution of MBMS service resources, MBMS Service transfer data. The application of the invention can avoid the main SRNC malfunction or failure of RNC out of step, realize the simple and effective way, to keep the whole network of RNC MBMS business MBMS business data synchronization, ensure the normal reception among RNC.
