How to mount a disk encrypted with cryptsetup(crypto_LUKS) in Ubuntu 14.04?

I have a 4TB Disk formatted as NTFS, and some data have been written into it. Then I tried to encrypt it and mapped it to /dev/mapper/volume_sde1 like that:

$ lsblk -io NAME,TYPE,SIZE,FSTYPE,UUID,MOUNTPOINT
sde                    disk   3.7T
`-sde1                 part   3.7T crypto_LUKS 485c6049-9e6c-4f4c-9b4d-9efe54a9497a
  `-volume_sde1 (dm-0) crypt  3.7T

Then I tried to mount it to some point:

$ mount /dev/mapper/volume_sde /up2s3

the mount says that:

mount: you must specify the filesystem type

then I add crypto_LUKS as the -t crypto_LUKS, mount still complain:

mount: unknown filesystem type 'crypto_LUKS'
