Abstract
Systems and methods of transporting internal radio base station (RBS) interface information over a packet network are presented. In one exemplary embodiment, in an interworking function (IWF) for communicating packets between a radio equipment (RE) and a radio equipment controller (REC) of a radio base station (RBS), a method may include receiving a packet sent from another IWF and having internal RBS interface information and residence time measurement (RTM) information that characterizes an asymmetry between processing times on links in different directions between the RE and the REC. Further, the method may include determining an asymmetry compensation that compensates for the asymmetry using the RTM information. Also, the method may include applying the asymmetry compensation to a timestamp of the internal RBS interface information to obtain an updated internal RBS interface information. In addition, the method may include transmitting the updated internal RBS interface information to one of the RE and the REC that is attached to the IWF.
