• continuous wave background
• postponed disappearance and sustainment of soliton

We reduce the variable-coefficient higher-order nonlinear Schrodinger equation (VCHNLSE) into the constant-coefficient (CC) one. Based on the reduction transformation and solutions of CCHNLSE, we obtain analytical soliton solutions embedded in the continuous wave background for the VCHNLSE. Then the excitation in advancement and sustainment of soliton arrays, and postponed disappearance and sustainment of the bright soliton embedded in the background are discussed in an exponential system.
