Brew® Mobile Platform (Brew MP) has four core software layers:

  • OS Services
  • Platform Services
  • Application Environment
  • Applications

Telephony is part of the Platform Services software layer under Modem Services, as shown in the following figure:

Telephony provides interfaces for these services:

  • Telephony

    The telephony interfaces provide functions to create and manage calls, register for and receive telephony events, retrieve phone information, and modify phone behavior.

  • SMS

    The SMS interfaces provide functions to register for and receive SMS notifications, send and receive messages, save and read saved messages, and configure the SMS broadcast service.

  • Dual SIM/Dual Standby

    Starting with Brew MP 1.0.3, telephony supports the Dual SIM Dual Standby (DS/DS) feature.

The Telephony Technology Guide contains a section, which describes the architecture of each service, the interfaces that provide the service, and use cases for each of these services.
