Patent ID: 7613152

Claim:
A dual mode terminal supporting different packet frame modes, comprising: a video chip having an application of packet data services and a data communication protocol processing packets received through a first communication network and a second communication network and transmitting the packets into the application; a Universal Asynchronous Receiver Transmitter (UART) interface and having a protocol stack relating to the first communication network; and a second network modem chip coupled with the video chip through an interface and having a protocol stack relating to the second communication network, wherein the data communication protocol of the video chip converts the Point to Point Protocol (PPP) packets received from a first network modem chip into Internet Protocol (IP) packets for the video chip, and the data communication protocol of the video chip converts IP packets in the video chip into PPP packets for the first network modem chip, wherein the data communication protocol internally processes IP packets from the application and provides the packets to the second network modem chip, and the data communication protocol receives the IP packets from the second network modem chip directly.
