A base station device broadcasts a base station identifier. The base station identifier is assigned to the base station device, and is broadcasted in one or more system information messages that are receivable by user devices located within a threshold distance from the base station device. The base station device determines whether the base station identifier is to be altered, and processes the base station identifier to generate an altered base station identifier for the base station device. The base station device performs one or more actions to cause the altered base station identifier to be broadcasted. The altered base station identifier is broadcasted in one or more additional system information messages that are receivable by the user devices.
