Pseudo-random series producing method for use in Markov paging test

Abstract

The base station stores the electric serial number sent by the mobile station. The base station takes the current GPS time every 20 ms. The 'exclusive or' logic operation is carried out between the absolute time obtained and the 32 digits set up at the mobile station. Whether the low 9 digits of the value of result with logic operation being executed is identical to the low 9 digits of the serial number or not is determined. If yes, the low 31 digits of the said value of result are assigned as the status value of the pseudo random sequence storage. Then, from the preset formula, the current status value of the pseudo random sequence storage is calculated and the Markov data frame utilized for link test is generated. The invented method solves the synchronization issue of generating pseudo random sequence and makes the statistics of the error frame rate of the force inverted link as well as monitors its quality.

Description

technical field [0001] The invention relates to a quality detection method suitable for forward and reverse traffic channel links in a code division multiple access (CDMA) system, in particular, a pseudo-random sequence generation method applied in Markov call testing. Background technique [0002] CDMA system performance test items often include testing the transmission quality of air traffic channels. The standard of transmission quality is generally represented by the frame error rate, so the more accurate the method for calculating the frame error rate, the more it can reflect the actual transmission quality of the air traffic channel. There are usually two methods to detect the transmission quality of the air traffic channel, one is the mobile station link loopback test, the test principle of this method is as follows: the base station sends a frame to the mobile station, and stores the frame rate, and the mobile station After receiving the frame, the station sends the...
