U.N. spokeswoman Marie Okabe said the 15-nation council would meet at 3 p.m. for closed-door consultations.
Prospects for concrete action by the council looked slim. China, which has a veto in the council, has always opposed sanctions on its neighbor Burma.
A statement issued by the office of Secretary-General Ban, who is currently visiting his native South Korea, said he "strongly deplores" the sentence on Suu Kyi and called for her release.
It said Ban urged Burma's military government "to immediately and unconditionally release" Suu Kyi, a Nobel Peace Prize laureate, and to "engage with her without delay as an essential partner in the process of national dialogue and reconciliation."
"Unless she and all other political prisoners in Burma are released and allowed to participate in free and fair elections, the credibility of the political process will remain in doubt," the statement said.
Suu Kyi was sentenced for violating an internal security law after an uninvited American visited her house where she was already under detention.
Fourteen of Suu Kyi's fellow Nobel peace laureates sent an open letter to the Security Council Tuesday urging it to set up a commission of inquiry into crimes against humanity they said had been committed in Burma.
"It is critical that the regime be held accountable for its crimes and that the full extent of its brutality be investigated," said the letter, which was released in Ottawa.
