Narrative:
This event occurred while we were in german airspace (5009n/00850e) at FL390 and using cpdlc (controller pilot datalink communication). We had been given frequency changes via cpdlc several times prior and responded to ATC. The frequency we were on became quiet. We requested a radio check. There was no response. Moments later; I transmitted on guard and received a few different frequencies from the other aircraft in the area and ATC. We were cpdlc and thus a limited number of verbal transmissions occurred. Our focus was primarily on recognizing frequency changes via cpdlc. I was able to hear communications on assigned frequency. When transmissions were no longer frequent; I promptly queried and discovered the loss of contact. In the future while in cpdlc airspace; I will request radio checks with ATC on a regular basis. Just as when using voice communication; cpdlc has the propensity of forgotten frequency changes by controllers.
