Overview

RIL (Radio Interface Layer) is a component used in the VELA platform. RIL consists of RILD, LIBRIL and REFERENCE-RIL to form a complete wireless communication architecture. It is an intermediate layer between the VELA system and the baseband. Through the RIL layer, the operating system can interact with the wireless communication hardware.

Module Introduction

Function Introduction

Rild

• Initialize the RIL layer: initialize LibRil and start Reference RIL.
• Receive upper-layer requests: Send the communication request of application to LibRil for processing.

LibRil

• Request conversion and command sending: Responsible for converting the requests into AT commands and send to the Reference-ril.
• Request reception and command response: The data responded by Reference-ril will be parsed by LibRil to ensure that the upper-layer application can handle these responses correctly.

Reference-ril

• Active request command: send AT command to Modem.
• Receive commands: Receive commands from LibRil or Modem.
