Narrative:
I was working the ramp tower. I had to hold traffic aircraft X on a spot waiting for their gate to open. Suddenly aircraft Y commenced to push without contacting my frequency. I tried to call aircraft Y but there was no answer. I made a couple of phone calls to find out who has talked to this flight and cleared it to push. After calling aircraft Y he answered and explained that he contacted a different frequency and [someone] cleared him to push and then to contact me. The person in charge this day of the other frequency knows the procedure that any flight on has to contact my frequency for push back or taxi to the gate. Having traffic already holding or moving inside the alley is a safety matter for us controllers; mostly when an aircraft is moving and we controllers do not have a way to contact them or stop their maneuvering; or to have them in frequency to amend any instructions given by someone else. This was two flights that could have resulted in serious conflict. One of the flights was on the frequency and the other flights was on operations frequency.
