1. A method of transmitting one or more branches of wireless signals between a channel processing unit and a remote radio frequency unit in a centralized base station, or between base stations through a packet network, each of said branches of wireless signals being a signal flow having a wireless frame period, the method comprising steps:

  • obtaining a sample data stream of wireless signal of each branch in said wireless signals;

    dividing said sample data stream into consecutive data segments of fixed length;

    encapsulating said data segments into application protocol packets according to a predetermined protocol, each application protocol packet further including first information indicating the sequence of the data segment of the packet in all the data segments of the branch to which the data segment belongs;

    second information indicating payload type of the branch;

    third information indicating whether the data segment of the packet contains a data sample corresponding to the start of a wireless frame period; and

    fourth information indicating the position of the data sample in the data segment if the third information indicates that the data sample corresponding to the start of the wireless frame period is contained; and

    encapsulating the generated application protocol packets into network protocol packets according to a network transport protocol and transmitting them to a specified target, wherein the network protocol packet further includes fifth information identifying one of said one or more branches to which the packet belongs, said fifth information and network transport source address and destination address uniquely distinguishing said branches.
