Abstract
A universal radio module for cellular communications devices is provided. The module can be plugged into any appropriately configured host device to supply the host device with cellular communication capability. The module can comprise three logical module-to-host interfaces—a voice interface, a data interface, and a management interface. The module may further comprise a Subscriber Identity Module (SIM) physical interface and/or an antenna physical interface.
Claims21
A communications module for performing radio communications functions in a cellular communications device, comprising:
- three logical module-to-host interfaces comprising:
- a module logical voice interface configured to communicatively connect to a cellular communications device logical voice interface;
- a module logical data interface configured to communicatively connect to a cellular communications device logical data interface;
- and
- a module logical management interface configured to communicatively connect to a cellular communications device logical management interface;
- a module antenna physical interface configured to physically connect to a cellular communications device antenna;
- a module multiplexer-demultiplexer configured to multiplex signals received on each of the module logical voice interface, module logical data interface, and module logical management interface into a transmission signal and provide the transmission signal to the module antenna physical interface;
- the module multiplexer-demultiplexer further configured to demultiplex a received signal received on the module antenna physical interface into a voice signal, a data signal, and a management signal;
- and
- the module multiplexer-demultiplexer further configured to provide the voice signal to the module logical voice interface, the data signal to the module logical data interface, and the management signal to the module logical management interface.
A host cellular communications device configured to interface with a communications module for performing radio communications functions, said host cellular communications device comprising:
- three logical host-to-module interfaces comprising:
- a host logical voice interface configured to communicatively connect to a module logical voice interface;
- a host logical data interface configured to communicatively connect to a module logical data interface;
- and
- a host logical management interface configured to communicatively connect to a module logical management interface;
- wherein the host logical voice interface, host logical data interface, and host logical management interface are configured on a host communications physical interface;
- a host antenna configured to physically connect to a module antenna physical interface;
- a host multiplexer-demultiplexer configured to multiplex signals transmitted from each of the host logical voice interface, host logical data interface, and host logical management interface into a transmission signal and provide the transmission signal to the host communications physical interface;
- the host multiplexer-demultiplexer further configured to demultiplex a received signal received on the host communications physical interface into a voice signal, a data signal, and a management signal;
- and
- the host multiplexer-demultiplexer further configured to provide the voice signal to the host logical voice interface, the data signal to the host logical data interface, and the management signal to the host logical management interface.
