Abstract
A computer-based method for processing user data traffic in a RAN in which mobile user equipment can communicate with a RNC through a base station includes the following steps. A flow of data frames to/from mobile user equipment passing between the base station and the RNC are read, wherein one or more of the data frames contain control messages and one or more other of the data frames contain user data. The control messages contained in the data frames are analyzed for channel identification information that indicates whether the data frames that contain user data contain circuit-switched or packet-switched user data. The data frames that contain the circuit-switched user data and the data frames that contain the packet-switched user data are segregated at a transport network layer between the base station and the RNC based on the channel identification information.
