Test Control

In order to verify the protocol conformance of radio resource control (RRC) connection reestablishment in LTE system, a new testing method is designed by implementing testing and test control notation version 3(TTCN-3) abstract test suit. Furthermore, the test suit is operated on the TTworkbench developed by German Testing tech. It also generates graphical presentation format (GFT) to check the protocol conformance of RRC functions. The scheme has been successfully applied in the project development of TTCN extended test set instrument in LTE system.

Random Access Channel

In this paper, we have analyzed and developed different types of algorithms related to 5G accessibility procedures for Non Standalone (NSA) and Standalone (SA) mode. The 5G accessibility depends on 5G radio parameters of each procedure, such as contention based Random access (CBRA), contention free random access (CFRA), Radio admission control (RAC), Radio resource control (RRC) and Radio bearer reconfiguration. The random access procedure for NSA is similar to SA mode. The goal is to improve the accessibility by optimizing timers and tune the main 5G radio parameters related to Random access channel (RACH), RRC reconfiguration and RAC procedures.

According to 3GPP latest standards, we give specific analysis of the AM (confirmed) mode data transmission process and the process of the function in this article, then we focusing on how to design and achieve PDCP(Packet Data Convergence Protocol ) confirmation mode based on the practical application . Including system design, primitive design and memory management, as well as what need to do during the boot. Confirmation mode is truly play its role in the reconstruction process, we elaborate the reconstruction process details of the reconstruction process from the point of view of RRC (Radio Resource Control) global angle and the the PDCP local angle . The program was fully proven to meet the requirements of the LTE system.

Effective Channel

For the multi-channel data acquisition system, crosstalk significantly affects the sample accuracy. Through analyzing the mode of multiplexer and the sampling timing sequence, we demonstrated that crosstalk effect mainly results from the switch of multiplexer for the low- frequency multi-channel data acquisition system. A new crosstalk testing method based on phase-shift rectangular waveform for the multi-channel data acquisition system was proposed. The phase-shift rectangular waveform was designed. Experiments were conducted to test crosstalk effect of the multi-channel data acquisition system. The experimental results were demonstrated that the proposed approach based on the phase-shift rectangular waveform exhibits a distinct feature in effective channel crosstalk testing, compared with waveforms of other types. Thus, the proposed method is effective to detect crosstalk of the multi-channel data acquisition system.
