Uttama said the initiative was being explored by the ministry along with other organisations and stakeholders.
He did not commit to a timeframe on when the proposal will be sent to the Cabinet for consideration but he said the ministry was not in a hurry to get it finished as it needed to be carefully considered.
The public needed to understand that the single gateway would save Internet businesses money, he said, because they would not have to invest in their own gateway.
Uttama added that the single gateway was still in the discussion stage.
He said businesses would not be forced to use the single gateway.
"It is to be done on a volunteer basis when we develop the infrastructure. It is not to force them. That is impossible," said Uttama.
