Method for connecting a mobile radio communication apparatus to a plurality of radio communication systems
First Claim
1. A method for connecting a mobile radio communication apparatus to a plurality of radio communication systems, comprising:
- defining a plurality of functions in a resource of a signal processing device, said functions including at least a modem function and a protocol function;
performing signal processing in said resource to transmit and receive a radio signal through a wireless transmitter-receiver device;
controlling said signal processing device to redefine, to the resource, another modem function and another protocol function corresponding to a respective one of the mobile communication systems;
executing a predetermined program in a general-use processor serving as another part of said resource;
redefining a circuit structure of at least one programmable hardware device serving as a part of said resource according to a set of a plurality of logic circuits which carry out basic calculations of at least a part of said signal processing;
determining respective shares of processing to be executed by said at least one programmable hardware device and the general-use processor in accordance with the contents of said signal processing; and
controlling said signal processing device to define, to the resource, the signal processing functions in accordance with determination of respective shares.
