User right change handling method and system

The invention provides a user right change handling method. A user terminal is accessed into a mixed-mode household base station in a closed way and then enters a connecting state, the closed user group right of the user terminal is changed, and when the access of the closed user group of the household base station is not allowed, a core network sends indication messages carrying special reason values to the household base station to indicate the right change information of closed user group of the user terminal; and after receiving the indication messages, the household base station indicates the user terminal to delete the closed user group information from an allowable accessed closed user group list, and executes the following operation of: initiating the switching from the user terminal to other cells, or relieving the connection of the user terminal on the household base station, or converting the closed-mode access of the user terminal into the open-mode access. The invention also provides a user right change handling system. The invention reduces the occurring probability of singling flow processes of switching, releasing and the like.
