Abstract
An interface between an application processor device and a modem device uses virtual local-area network (VLAN) tagging of Ethernet frames. An example modem device includes a first interface circuit configured to communicate with a remote device, a second interface circuit configured to communicate with an application processor circuit , and a processing circuit configured to: provide the application processor circuit with IP-based data communications to and from at least one remote IP network using Ethernet frames exchanged between the application processor circuit and the modem device; provide the application processor circuit with local modem services, using Ethernet frames exchanged between the application processor and the modem device; and distinguish between Ethernet frames for the local modem services and Ethernet frames for the IP-based data communication to and from the remote IP network using differing VLAN identifiers attached to or included within the respective Ethernet frames.
