Narrative:

Departing corona, ca, for santa barbara route of flight direct pomona VOR direct santa barbara (through chino class D airspace and ontario class C). I had established communication with chino tower before takeoff at corona and once airborne received a clearance to transit their class D airspace. I relayed that I would like a handoff to socal for further climb to 8500 ft (through the class C airspace starting at 2700 ft MSL). I attempted contact with socal, who replied with 'all aircraft standby.' inadvertently, I continued the climb. At 3100 ft I realized this, leveled off, turned wbound away from the primary airport (ontario) and established contact with socal. No traffic conflicts involved. No disciplinary response from socal. Pilot inattentiveness to altitude when a temporary level off was necessary, was the cause. Problem was not caused by the airspace system.
