US 2014/0155041 A1 · RADIO INTERFACE LAYER DESIGN FOR SMARTPHONES

Abstract

A method and system communicates a request between a user application and a modem within a wireless communication device. A radio interface layer (RIL) architecture includes an application framework which receives a hardware specific request as a first application programming interface (API) call from the user application. In response to receiving the request, the application framework sends a corresponding, second API call to a vendor radio interface layer (Vendor RIL) which provides an interface configured for communicating with a specific type of transceiver or modem. In one embodiment, the second API call is transmitted via a Java Native interface (JNI). The JNI provides access to software programs associated with the transceiver, which programs are written in a language that is different from Java. The Vendor RIL communicates with the modem using a modem protocol software corresponding to the specific type of modem to perform commands associated with the request.

Dependent claims

A wireless communication device comprising:

at least one processor;
a modem communicatively connected to the at least one processor;
a storage sub-system;
an application module located within the storage sub-system and which includes a user interface application that initiates a first application programmable interface (API) call based on a received request;
and
a radio interface layer (RIL) architecture configured to support communications between the user interface application and the modem and which includes a hardware dependent application framework that, in response to receiving the first API call from the application module, sends a corresponding second API call to a vendor radio interface layer (Vendor RIL), which provides an interface configured for communicating with a specific type of modem using a modem protocol software corresponding to the specific type of modem in order to perform a command associated with the received request.

A method for communicating between an application module and a modem within a wireless communication device, the method comprising:

initiating a first application programmable interface (API) call based on a received request;
detecting receipt of the first API call from the application module at a phone application of a hardware dependent application framework within a radio interface layer (RIL) architecture;
in response to detecting receipt of the first API call at the phone application, sending a corresponding second API call to a vendor radio interface layer (Vendor RIL) which provides an interface configured for communicating with a specific type of modem;
and
initiating communication between the Vendor RIL and the specific type of modem using a modem protocol software to perform a command associated with the received request.
