Mobile communication system and method of data dispersion in said system

A data dispersing method of dispersing data in a mobile communication system having a plurality of radio network controllers and a plurality of radio base stations connected to each of the radio network controllers, for sending and receiving user data between a host network and mobile stations via said radio network controllers and radio base stations, comprising steps of:

• setting up a plurality of transmission paths, each of which passes through at least a different radio network controller, between a base station, which sends and receives radio signals to and from a mobile station, and the host network;
• when user data is transmitted between the host network and a mobile station, dispersing the user data by passing said user data through said plurality of transmission paths;
• monitoring traffic conditions on a transmission path at one radio network controller on said transmission path;
• on the basis of said traffic conditions, said radio network controller requesting another radio network controller, which controls a call on said transmission path, to perform dispersion of the user data by a plurality of transmission paths;
• and
• said requested radio network controller exercising control so as to disperse said user data to a plurality of transmission paths.

• terminating user data, which is sent and received to and from the host network via a plurality of transmission paths, transmission path by transmission path by a retransmission control protocol at a radio network controller on each transmission path;
• terminating the user data, transmission path by transmission path, by respective ones of a plurality of retransmission control protocols at a mobile station;
• and
• transmitting and receiving the user data as a separate data stream on each transmission path.
