1 page.title=Radio Layer Interface
19 <p>Android's Radio Interface Layer (RIL) provides an abstraction layer between Android telephony services (<a href="http://code.google.com/android/reference/android/telephony/package-descr.html">android.telephony</a>) and radio hardware. The RIL is radio agnostic, and includes support for Global System for Mobile communication (GSM)-based radios. </P>
30 <li><b>Vendor RIL</b>: The radio-specific Vendor RIL of <code>ril.h</code> that processes all communication with radio hardware and dispatches calls to the RIL Daemon (<code>rild</code>) through unsolicited commands.</li>
112 <p>To implement a radio-specific RIL, create a shared library that implements a set of functions required by Android to process radio requests. The required functions are defined in the RIL header (<code>/include/telephony/ril.h</code>).</p>
113 <p>The Android radio interface is radio-agnostic and the Vendor RIL can use any protocol to communicate with the radio. Android provides a reference Vendor RIL, using the Hayes AT command set, that you can use as a quick start for telephony testing and a guide for commercial vendor RILs. The source code for the reference RIL is found at <code>/commands/reference-ril/</code>.</p>
126 <p>Your Vendor RIL must define a RIL_Init function that provides a handle to the functions which will process all radio requests. RIL_Init will be called by the Android RIL Daemon at boot time to initialize the RIL.</p>
132 <p>RIL_Init should return a RIL_RadioFunctions structure containing the handles to the radio functions:</p>
166 <p>Must be completed with a call to <code>RIL_onRequestComplete()</code>. <code>RIL_onRequestComplete()</code> may be called from any thread before or after this function returns. This will always be called from the same thread, so returning here implies that the radio is ready to process another command (whether or not the previous command has completed).</p></td>
170 <td valign="top">This function should return the current radio state synchronously.</td>
