Patent ID: 7764693

Claim:
A radio communication system transmitting and receiving data between a radio terminal and a base station control equipment via at least one communication path selected at the base station control equipment from among a plurality of communication paths having a different communication speed from each other, the radio communication system comprising: the base station control equipment for selecting the plurality of communication paths for communicating with the radio terminal, and transmitting data frames each having the same sequence number to the radio terminal via the plurality of communication paths having been selected; and the radio terminal for receiving each of data frames transmitted from the base station control equipment through the plurality of communication paths, and sending back an ACK signal for responding to each data frame having been received through each communication path, wherein, the base station control equipment receives each of the ACK signals sent back through each communication path, and determines one of communication paths, through which the ACK signal has arrived earliest, for the communication path to transmit subsequent data frames to the radio terminal, and ignores rest of the ACK signals for the same data frame arrived later.
