The Design And Realization Of The Digital Trunking Terminal Air Interface Protocol Based On CDMA2000

This paper optimizes and improves the paging,handoff and power control techniques of the CDMA2000 1X wireless interface protocol according to the features of the trunking communication. Moreover, a new protocol of paging, handoff and power control used in trunking communication environment is designed, and a description of the software implementing flow of this design in the trunking mobile station is given.First, a brief introduction to the wireless interface protocol of CDMA2000 1X and the software implementing flow of the call processing of this protocol in the trunking mobile station is presented in this paper, a description of frame work of the trunking system based on CDMA2000 1X is given out and the position of this design in the trunking system is pointed out. Then, a paging technique based on a shared channel is designed. At the same time, the implementing flow of this paging technique in the trunking mobile station is presented. Further more, according to the characteristics of the shared-channel, a handoff method implemented by the mobile station independently is provided. Still, a description of the software implementing flow in the trunking mobile station is given. Finally, according to the characteristics of the shared-channel, a new design used for the forward power control is put forward, simulation is made to testify the design of this part.
