Note (1): The 13 series GSM specifications relate to European-Union-specific regulatory standards. On the closure of ETSI TC SMG, responsibility for these specifications was transferred to ETSI TC MSG, (Mobile Specification Group) and they do not appear on the 3GPP file server.
Note (2): The specification of these aspects are spread throughout several series.
Note (3): Algorithms may be subject to export licencing conditions. See the relevant 3GPP page. See also the relevant ETSI pages.
Note (4): The original GSM algorithms are not published and are controlled by the GSM Association.
