Abstract:
1. A communication processing method used in a network gateway device, wherein the network gateway device is coupled to a wireless terminal through a first wireless network and to a base station through a second wireless network different from the first wireless network, the communication processing method comprising: maintaining a first Transmission Control Protocol (TCP) link between the network gateway device and the wireless terminal through the first wireless network, when the transmission performance of the first wireless network as measured by the network gateway device is larger than a first threshold value; maintaining a second TCP link between the network gateway device and a service providing server through the second wireless network, when the transmission performance of the second wireless network as measured by the network gateway device is larger than a second threshold value; determining which TCP link between the first TCP link and the second TCP link is to be optimized, based on whether or not the transmission performance to be improved between the wireless terminal and the service providing server is larger than a third threshold value, wherein the transmission performance to be improved comprises packet loss rate, transmission delay or an inverse of transmission rate for a current TCP transmission; and performing a TCP transmission optimization on the determined TCP link between the first TCP link and the second TCP link to be optimized, so as to reduce/improve at least one of packet loss rate, transmission delay and transmission rate for the current TCP transmission corresponding to the determined TCP link to be optimized, till the transmission performance of the determined TCP link between the first TCP link and the second TCP link is smaller than or equal to the third threshold value, thereby improving a corresponding transmission performance between the wireless terminal and the service providing server.
