For the blazar 3C454.3 the size of the accretion disk that is not less than the diameter of the orbit of the companion estimated. We have studied a fragment of the flare lasting about five months (about 20% of the orbital period) in the optical, X-ray, and gamma-ray. In all these ranges, this flare fragment has a two-peaked structure, possibly due to the companion’s passage through regions of enhanced matter density in the accretion disk. The scale of these inhomogeneities is of the order of the gravitational radius of the central SMBH. The dynamics of a powerful flare in 1996, based on S0528+134 observations in the range (0.1-300 GeV), X-ray (2-10 keV, 15-50 keV) and radio wavelengths are discussed. The delay effects between different ranges of wavelengths and the radio frequencies are derived. On the basis of the original data from the X-ray, optical and radio wavelengths from 2004 to 2013 the dependence of the delay effects of X-ray bursts from the radio range of wavelengths to which obeys the logarithmic law are determined. Based on the analysis of multi-frequency monitoring in the radio bands, the orbital period and the precession in a binary system of supermassive black holes in S0528+134 and the physical characteristics of the system are estimated.
