Efficient operations of components in a wireless communications device

A method of communicating between components in a wireless device, the method comprising:

• receiving service requests at a controller interface module, the service requests being sent from an abstraction module in an applications subsystem;
• translating the service requests at the controller interface module into a form understandable and executable by an interface module in a communications subsystem, the controller interface module being a separate component from either the communications subsystem or the applications subsystem, the controller interface module maintaining a mapping between service handles and a service groups, the control interface module to responding to queries from the application subsystem and the communication subsystem by making a determination of supported extended service groups, and the communications subsystem being programmable only to interact with the controller interface module and the applications subsystem being programmable only to interact with the controller interface;
• sending the translated service request from the controller interface module to the interface module;
• and
• executing the service request at the interface module.

A wireless client device for communicating between components, the wireless client device comprising:

• an applications subsystem including an applications module to execute an operating system application and user applications on the wireless client device, and an abstraction module to abstract protocol operations received from the applications module;
• a communications subsystem including an antenna, and a protocol software module electrically coupled to send signals to and receive signals from the antenna;
• and
• a controller interface module that is a separate component from either the communications subsystem or the applications subsystem and that is communicatively coupled to both the applications subsystem and the communications subsystem, the controller interface module being configured to translate all data signals from the applications subsystem into signals that are executable by the communications subsystem, the controller interface module being further configured to translate data signals from the communications subsystem into signals that are executable by the applications subsystem, the controller interface module being configured to maintain a mapping between service handles and a service groups, the control interface module being further configured to respond to queries from the application subsystem and the communication subsystem by making a determination of supported extended service groups, and the communications subsystem being programmable only to interact with the controller interface module and the applications subsystem being programmable only to interact with the controller interface.
