Media Access Control Of Wcdma Radio Network Controller Equipment And Realization

In this thesis, the author designs and effectuates MAC protocol software, which works in the RNC of the 3rd generation mobile communication. The software is featured by its high efficiency, reliability, realtime property and ect. Its design model and effectuation measure are worthwhile to dawn upon and populanize in the development of realtime data transmission software. MAC software is a vital component of the 3rd generation mobile communication air interface protocols It's design and realization will enable our country to produce the 3rd generation mobile communication equipment in the name of its own intellectual property right.The software refers to 3GPP TS 25.321 (MAC protocol specification) Potocol. Its hardware system uses high-quality communication processor 8260 of Motorola. It software system has as it core the multitasking mechanism under the embedding realtime operation system. Moreover, It dawns upon picture user boundary Tornado 2.0 as it development environment, and is strictly based on protocol model.Facts prove that the system has the following advantages:1: It can arrange and rearrange flexibly and effectively.2: It operates smoothly and save system resourse such as internal memory.3: It boasts of a high processing spreed and an excellent realtime property.
