The obvious solution would be that your controller adds the necessary 
parameters to a record in a table that represent a queue with reports to 
be generated.
A scheduler task (quite easy to program; there is also support in 
extbase for scheduler tasks) that runs every few minutes can process the 
report generations that are waiting in the queue and send the result to 
the user.
A bonus is that the scheduler task will be executed in CLI context which 
has no maximum execution time.
