Welcome to iMore! Maybe you need to clear some space. Delete some apps, music, messages, etc. How much available space do you have?

You can also try connected your iPhone to a Mac or PC via USB and using iTunes to update to 9.2.1. Using iTunes doesn't use as much storage space because it doesn't have to preload the installation files onto your device, rather it loads them into iTunes and then pushes the core iOS files to your device.
