Er thats how UMTS 3g works. It turns off the tranciever and receiver power needs when in active. The technical terms are Discontounius Transmission and reception DTX/DRX. It has some intelligence on what the turn off vs turn on times are also,especially important when making voice calls or there is a delay in traffic, you dont want the link to drop cause the system turned of the power.

heres a good overview.
