The embodiments of the present invention can improve flexibility and an emulation degree of traffic simulation.

Abstract: A preprocessing method for cooperative communication and a base station and a system for executing the method are provided. The method includes: obtaining a common base station group from a cooperative base station group of a user terminal, in which the common base station group includes a set of base stations providing a cooperative service for other user terminals in the cooperative base station group; and calculating a first precoding matrix of the user terminal according to the common base station group, in which the first precoding matrix is used to perform elimination preprocessing on interference from the user to other user terminals served by the common base station group. The method reduces Multi-User Interference (MUI).

Abstract: A method, an apparatus and a system for cooperative resources scheduling and cooperative communication are provided. The method for cooperative resources includes: obtaining, by a network central controller, statistical information of all the users dominated by it in a first time period, dividing base stations to base station cooperative clusters according to the statistical information, and transmitting cooperative cluster dividing result to the base stations. The corresponding method and apparatus for cooperative communication are also provided. The solutions of the embodiments of the present disclosure can increase the transmission rate and user experience for the users at the edge of the cooperative cluster, and improve the fairness of the system users, while reducing the signaling overhead of the system, separating the computational tasks and reducing the difficulty of implementing the whole system.

Abstract: The present invention relates to mobile communication technologies, and discloses a method and an apparatus for registration, communication, and handover of a Mobile Node (MN). The present invention is intended to overcome the bottlenecks of data traffic and processing capability in the home network in the prior art. A distributed mobility management system is provided herein. The system includes at least two Mobility Management Anchors (MMAs): any two MMAs are interconnected; at least one terminal exists in each MMA connection; each MMA stores a terminal binding relationship table; and the terminal binding relationship table records identifiers (IDs) and Internet Protocol (IP) addresses of terminals. The distributed mobility management system under the present invention can balance load, improve the data processing capability, simplify the signaling interaction in various procedures, and improve the system processing capability.
