  • System and method for emulating a telephony driver
    Patent number: 7277700
    Abstract: A system and method for emulating a telephone driver of a mobile device to assist in the development and testing of mobile telephony applications is described. An emulated telephony driver maintains internal states of a wireless network and characteristics of the mobile device. A wireless network is simulated such that neither a cellular radio nor a mobile subscription are required for handset application development and testing.

  • Subscriber identification module (SIM) emulator
    Patent number: 7162408
    Abstract: Embodiments of the present invention relate to methods, systems, and computer-readable media for emulating a Subscriber Identification Module (SIM). SIM emulation comprises reading configuration data representing one or more characteristics of the SIM. Execution of the emulation is then initiated. A SIM command is received from a Radio Interface Layer (RIL) to access resources of the SIM. The SIM command is handled in a manner consistent with operation of the SIM based on the configuration data. Data related to the SIM command and handling of the command is logged.
