Why Allah(SWT) addressed Isa/Jesus(pbuh) as "Isa-Ibn-Maryam/Son of Mary(pbuh)" consistently?

Allah(swt) could've addressed Isa/Jesus(pbuh) as only Isa/Jesus(pbuh) instead, he addressed him as "Isa-ibn-Maryam(pbuh)" why is that? Was it to signify his miraculous birth or something else? Or it signifies something more grandeur? And it sounds very sweet Isa-ibn-Maryam(pbuh) rather solely Isa(pbuh), was it a purpose to make the Qur'an more melodious and eloquent?
