The present invention relates to a method for implementing broadcast/multicast area management in a wireless communication system. The method mainly comprises: firstly configuring and storing information of the broadcast area in a network entity of the wireless communication system; then sending a request message to the network side entity when a client terminal in the wireless communication system needs to obtain the broadcast/multicast service, and the network side entity performs area authentication on the subscriber's request message according to the configured information of the broadcast area so as to support management of broadcast programs based on location areas. Meanwhile, the network side may initiate establishment of a service stream with the configured location area.
