Third Generation Mobile Communication (wcdma) Systems Radio Access Network Application Part (ranap)

The high layer signaling - Radio Access Network Application Part (RANAP) is a very important part of Iu intertface in the Third Generation Mobile Communication System. It is designed and realized in this paper. We are mainly in charge of the side of Radio Network Controller (RNC ) . The design and realization of RANAP plays a very important role in the independent development of the Third Generation Mobile Communication System device of our China.The system utilizes Finite State Machine ( FSM ) as the basement of system design and realization.. Hardware system takes the compactPCI embeding system as the core. which includes two pieces of main CPU processing cards - SUN-CP2040. two pieces of auxiliary CPU processing cards - SUN-CP2060 and two pieces of I '0 cards. Software system takes real-time mutilple task and mutiple thread mechanism under Solaris as the kernel. We utilizes standard c language as the developing enviroment. which improves the software's running-speed and system resourse's occupation...
