The next number is

132119312211

And the pattern is

The famous 'say what you see pattern' - usually done with 1s and 2s - so in the first number, there is one 9 and two ones, so the second number is 1921

The next number in the series should be:

132119312211

The pattern is:

A given number in the sequence, n, describes the previous number in the sequence, n - 1. For example: 1921 describes 911 because there is one 9 and two 1s.
