We analyzed the radio light curves of 3C 454.3 at frequencies 22 and 37 GHz taken from the database of Mets(a)hovi Radio Observatory, and found evidence of quasi-periodic activity. The light curves show great activity with very complicated non-sinusoidal variations. Two possible periods, a very weak one of 1.57 ± 0.12 yr and a very strong one of 6.15 ± 0.50 yr were consistently identified by two methods, the Jurkevich method and power spectrum estimation. The period of 6.15 ± 0.50 yr is consistent with results previously reported by Ciaramella et al. and Webb et al. Applying the binary black hole model to the central structure we found black hole masses of 1.53 × 109M⊙ and 1.86 × 108M⊙, and predicted that the next radio outburst is to take place in 2006 March and April.
