Claim Text:
1. A method of reducing traffic transmission between a modem of a mobile terminal and a host processor separate from the modem, the method comprising: receiving, by the modem from a wireless network via a wireless interface coupled to the wireless network, a unit of data at the radio link control (RLC) level; converting, by a processor in the modem, the RLC level unit of data to a transport control protocol (TCP) unit of data; determining, by the modem, if the newly arrived TCP unit of data is a duplicate of an earlier received TCP unit of data, wherein, if the newly arrived TCP unit of data is not determined to be a duplicate of the earlier received TCP unit of data, the newly arrived TCP unit of data is sent to the host processor over an interface that is not part of the wireless network; if the newly arrived TCP unit of data is determined to be a duplicate of the earlier received TCP unit of data, determining, by the modem, if an acknowledgement of the earlier received TCP unit of data has been received by the modem from the host processor over the interface that is not part of the wireless network, wherein, if the acknowledgement of the earlier received TCP unit of data has not been received by the modem, the newly arrived TCP unit of data is sent to the host processor over the interface that is not part of the wireless network; and if the newly arrived TCP unit of data is determined to be a duplicate of the earlier received TCP unit of data and the acknowledgement of the earlier received TCP unit of data has been received by the modem, discarding the newly arrived TCP unit of data.
