Claim:
1. An application processor circuit comprising: an interface circuit configured to communicate with a modem device; and a processing circuit; wherein the processing circuit is configured to: access one or more modem services on the modem device, using the interface circuit and an IP socket application protocol interface (API), wherein packets sent to the modem device for accessing the one or more modem services include a destination IP address corresponding to the modem device; and identify and discard outbound packets that include a destination IP address corresponding to the modem device and that originate from any of one or more disallowed applications in the application processor, without sending the identified packets to the modem device, wherein the processing circuit is configured to identify packets that originate from a disallowed application by identifying packets that originate from a disallowed category of applications, and wherein the processing circuit is configured to identify packets that originate from a disallowed category of applications by determining an operating system access group for the originating application and determining that the operating system access group does not match any of one or more allowed operating system access groups.
