Method for accessing control terminal to shared network and access network element

The invention discloses a method for accessing a control terminal to a shared network and an access network element, and belongs to the field of communication. The method comprises the following steps of: determining a public land mobile network (PLMN) of a terminal which is forbidden to access a shared network, and broadcasting access forbidding information including information on the determined PLMN of the terminal which is forbidden to access the shared network, or broadcasting access forbidding information and the PLMN of the terminal which is forbidden to access the shared network, so that the terminal can obtain information on the PLMN of the terminal which is forbidden to access the shared network and can judge whether the terminal is forbidden to access the shared network; and therefore, the problem that an operator of the shared network is inconvenient to distinguish and control corresponding users because a wireless communication network just can simultaneously forbid all PLMN terminals in the network sharing.
