Problems solved by technology

[0002] In the wireless communication system, when the clock is wrong, the demodulator will not be able to demodulate the signal, resulting in the phenomenon that the mobile station has a signal but cannot make a call. When this happens, if no measures are taken If it is processed, it will seriously affect the service quality of the system

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] FIG. 1 is a flowchart illustrating a clock detection method for a wireless communication system according to the present invention.

[0018] Referring to Fig. 1, the clock detection method for wireless communication system according to the present invention comprises the following steps:

[0019] Step S102, calculating the first difference between the transmission time and the reception time when the system is initialized; Step S104, setting a periodic timer, and calculating the second difference between the transmission time and the reception time at each timing arrival time of the periodic timer; Step S106, calculating the absolute value of the difference b...

Abstract

The invention discloses a clock detecting method for a wireless communication system, wherein the method comprises following steps: step S102, calculating a first differential value of sending time and receiving time when the system is initialized, step S104, arranging a cycle timer, calculating a second differential value of sending time and receiving time when each timing of the cycle timer achieves setting time, step S106, calculating absolute value of differences between the second differential value and the first differential value as a third differential value, and step S108, comparing the third differential value and a first threshold value, and confirming whether the clock makes mistakes or not according to the compared result. The condition that the clock is false to alarm when in normal or fail to alarm which in abnormal can be avoided through the clock detecting method of the invention, and therefore the corresponding process can be carried out when the clock is in false.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a clock detection method for a wireless communication system. Background technique [0002] In the wireless communication system, when the clock is wrong, the demodulator will not be able to demodulate the signal, resulting in the phenomenon that the mobile station has a signal but cannot make a call. When this happens, if no measures are taken If it is processed, it will seriously affect the service quality of the system. In this regard, some methods should be adopted to detect the clock in the wireless system, so what method to use for clock detection is very important. When the clock is wrong, it needs to be able to detect it accurately and in time, and when the clock is not wrong, it cannot be wrong. reported situation. Contents of the invention [0003] The purpose of the present invention is to provide a clock detection method used in a wireless communication syste...
