South Tyrol was once part of the wider Austro-Hungarian empire but was annexed by Italy in 1918.
The scaling up of security at Brenner Pass has already been a point of contention in recent times when Austria was forced to send more than 300 police officers to the landmark as violent clashes erupted during pro-immigration demonstrations last year.
UNHCR says 84,830 migrants and refugees have reached Italy's shores so far this year from Libya, which is a 19-percent increase from last year.
In a new report on migration trends in Libya issued today, UNHCR noted that largely lawless Libya has become a major thoroughfare for migrants, but patterns of movement are changing.
There was no immediate comment from Italy or EU officials, but Doskozil's spokesman said there was no concrete timetable for the new controls.
The spokesman added: 'We'll see how the situation in Italy is becoming more acute and we have to be prepared to avoid a situation comparable to summer 2015.'Italy has taken in more than 80,000 refugees and migrants so far this year, most of whom arrived by boat from Africa, making Italy the main point of entry to Europe.
In 2015, Austria introduced checks on the border with Hungary and the new measures would affect the country's Brenner Pass.File photo Austria has already moved heavy equipment to the province of Tyrol, which borders Italy, including four armoured vehicles to block roads, the spokesman said, adding: 'These are not battle tanks.These are armoured vehicles without weapons which could block roads.This year alone, more than 100,000 migrants have arrived in Europe by sea, according to the UN refugee agency.It prompted Italy to beg other European countries to accept migrant ships and threatened to close its ports as the nation struggles to deal with record numbers.
More than 100,000 migrants have made their way into Europe already this year, mainly from Africa and the Middle East.
