Following OnAir's series of tests that showed electromagnetic radiation of onboard GSM mobiles being lower than 1% of the limits endorsed by the World Health Organization and so significantly below radiation levels of common terrestrial emission levels, inflight usage of mobile phones is considered harmless to passengers' health.
They run on telephony-based infrastructure such as AMPS or GSM.
A MSRN is assigned for every mobile terminated call, not only the calls where the terminating MS lives on a different MSC than the originating MS. Although this seems unnecessary since many vendors' VLR's are integrated with the MSC, the GSM specification indicates that the MSC and VLR (Visitor Location Register) do not need to reside on the same switch.
As a mob unit engaged in a call moves away from a cell site or formally known as Base transceiver station and its signal weakens, the BSC(GSM) or RNC(3G UMTS) will automatically instruct it to tune to a different frequency, one assigned to the newly entered BTS.
