do cellphones transmit signals even during standby mode and at what power?

GSM phones transmits signal at certain intervals to the nearest BTS so that the network will know where it is currently located. Temporary information about that mobile will be stored to the VLR (visitor Location Register)so that the next time the user wants to initiate or receive a call the MSC will know its current position.
