India, considered the second biggest draw after Australia, are likely to tour in 2007 and again in 2011.
But the agreement is subject to the International Cricket Council's tours programme being relaxed next month.
"We told the Indian board we are open to a four-year cycle but details are to be worked out," said an England and Wales Cricket Board spokesman.
India played an extra one-day series in England in September 2004, packing grounds for three matches prior to the ICC Champions Trophy.
