You have 2 options

1. wait until its approved and released in your country/region or by your carrier/network

or 

2. manually update your phone

I know my problem is in country and/or operator.
But my friend make update on his Xperia SP on regular way with PC Companion.
He buy phone and sim card from one mobile operator.
My phone I buy from another operator but my sim card is from same operator like my friend.
I don't understand why my phone don't want to update.

Thank

Indeed, the issue is your network/carrier, not Sony, as they have to approve and release the update.
