Configuration data is transferred from a data source 110, such as a software download server, to a software defined radio apparatus 130, particularly a mobile telephone, via an intermediate apparatus 120 which has means 126 for storing the data received from source 110 prior to onward transfer to the radio 130. The data may be transferred from server 110 to intermediate apparatus 120 at a time selected by apparatus 120 or by server 110, or at a predetermined time or times set by an overall system control. Alternatively, a request for configuration data may be sent from radio 130 to server 110 via apparatus 120 or via a route not involving apparatus 120. The link 115 between server 110 and intermediate apparatus 120 may be a standard telecommunications link, or may take place via a mains power network which is convenient if the apparatus 120 also includes a mains based battery charger 125. In that case, apparatus 120 can simultaneously charge the battery 131 of the radio and transfer configuration data to radio 130 from store 126 when the radio 130 has been coupled to the apparatus 120 via connectors 127, 137. The configuration data may be related to operation on one or more vocoding schemes, or to operation of multimedia functions, or to operation on one or more multiple access schemes, such as TDMA, CDMA, GSM, UMTS, AMPS, CDMA 2000, wideband-CDMA, combined TDMA/CDMA, iDEN, EDGE, IS 136, IS 95A/B, TETRA. |
