Abstract
The invention relates to the field of radio communication devices and, more specifically, gateways connected firstly to a cellular radio communication network via a packet data communication network, such as an IP network, and secondly to cellular mobile communication terminals. The invention proposes to use the same oscillator to provide both the reference clock of the radio subsystem and the reference clock of the general processor of the device. The fact that the same oscillator is used for these two components also allows embodiments in which some of the functions that have hitherto been devolved to a hardware control component, itself operating by means of a clock derived from the radio oscillator and being involved in the control of said oscillator, can now be devolved to a software component that is executed on the general processor of the gateway.
