Method and apparatus for operating an exhaust-gas catalytic converter () of an internal combustion engine having at least one cylinder (Z-Z) and one exhaust-gas section (), in which the exhaust-gas catalytic converter () and a lambda probe () downstream of the exhaust-gas catalytic converter () are arranged. A characteristic value which is representative for the NOx concentration is determined as a function of a measured signal (VLS DOWN) of the lambda probe ().
