Patent ID: 8619783

Claim:
A terminal coupler for a wireless communication, comprising: a sequence number assignment unit for sequentially assigning sequence numbers to data packets received from a terminal end device, and performing processing such that the data packets with the sequence numbers assigned thereto are individually transferred to a plurality of communication terminals belonging to a same group in conformity with preset scheduling policies; a packet transfer unit for reordering the data packets, received from the plurality of communication terminals belonging to the same group by sequence numbers included in the data packets, and transferring the reordered data packets to the terminal end device; a communication unit for setting up a plurality of communication channels between the terminal end device and a base station using the plurality of communication terminals; and a control unit for determining whether a new communication terminal isthe first to connect to the terminal coupler in a relevant group after the connection between the new communication terminal and the base station has been set up, wherein the communication unit is configured such that, when the new communication terminal is connected to the terminal coupler, the communication unit requests the new communication terminal to set up a connection with the base station, thus enabling a connection between the new communication terminal and the base station to be set up and the control unit performs processing such that if it is determined that the new communication terminal is not the first to connect to the terminal coupler in the relevant group, a group join request message including a group identifier of the relevant group is sent to the new communication terminal; and if it is determined that the new communication terminal is the first to connect to the terminal coupler, the terminal end device is assigned an Internet Protocol (IP) address by the base station via the new communication terminal.
