Abstract: The method for controlling an overload cell in a CDMA Mobile System comprises the steps of: a first step of receiving information on the overload cell from an overload detection module within a base station controller to retrieve the information on the load of neighboring cells and calculating the information on the total overload of neighboring cells; a second step of determining whether or not the total overload of the neighboring cell in a second hierarchy is greater than the maximum value of the neighboring cells; a third step of informing the overload detection module of the impossibility of control and terminating the procedure when it is determined that the total overload of the neighboring cell in the second hierarchy is not greater than the maximum value of the neighboring cells; a fourth step of retrieving a cell group as a third hierarchy with minimum load when at the second step it is determined that the total overload of the neighboring cell in the second hierarchy is greater than the maximum value of the neighboring cells; and a fifth step of increasing forward power of the cell with minimum load to expand a service region and handoffing a moving subscriber call in the vicinity of the neighboring cell of the overload cell to the expanded cell.

Abstract: Disclosed herein is a system and method for coupling communication terminals. In a communication method performed by a terminal coupler according to the present invention, sequence numbers are sequentially assigned to data packets received from a terminal end device. 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. Data packets, received from the plurality of communication terminals belonging to the same group, are reordered by sequence numbers, and the reordered data packets are transferred to the terminal end device.

Abstract: A mobile station and a base station communicate with each other using a frame including one or more downlink subframes and one or more uplink subframes. The base station begins the transmission of a data burst in a subframe corresponding to a downlink subframe index. The mobile station transmits feedback for the data burst to the base station in a subframe corresponding to an uplink subframe index. If the frame uses a time division duplex scheme, the uplink subframe index is determined by at least using the downlink subframe index and the parameter value.
