The RIL Adapter module provides functions such as vendor library loading, service interface implementation, and event scheduling and management. The module shields the differences of modems supplied by different vendors to provide a unified interface for the telephony service layer. It communicates with the telephony service layer by registering a Hardware Driver Foundation (HDF) service.
