  Recently, the higher-order Carlitz's q-Bernoulli polynomials are represented
as q-Volkenborn integral on Zp by Kim. A question was asked in [13] as to
finding the extended formulaeof symmetries for Bernoulli polynomials which are
related to Carlitz q-Bernoulli polynomials. In this paper, we give some new
identities of symmetry for the higher-order Carlitz q-Bernoulli polynomials
whch are derived from multivariate q-Volkenborn integrals on Zp. We note that
they are a partial answer to that question.
