Embodiment Construction
[0025] The technical solution of the method of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] In this embodiment, for every certain number of base stations, such as every 20 base stations, a base station responsible for synchronous monitoring is set up, which may be called a "synchronous monitoring base station" to monitor the frame synchronization of surrounding base stations. The synchronous monitoring base station can normally work and absorb traffic like other base stations; however, it has a synchronous detection function and can be called out of operation periodically (such as every 30 minutes, 1 hour, 2, 3, 4, 5 , 6...) to monitor the synchronization status of the surrounding base stations, and report an alarm to the network management when an abnormality is found in the monitoring. Each detection process is completed in about 5 minutes. After the detection is completed, no...

The present invention discloses a synchronous monitoring method for a wireless system base station. Firstly, a synchronous monitoring base station and relevant synchronous monitoring parameters are arranged for a preset quantity of base stations. And then, taking its time as reference, the synchronous monitoring base station checks synchronization of surrounding base stations and calculates synchronous time slot deviations. As the synchronous time slot deviations of the monitored base stations exceed a preset threshold value, warning information is reported to a network administrator according to a warning selection algorithm. After receiving the warning information, the network administrator output requirement for base stations to be adjusted based on original data of synchronous monitoring and dispatches a command of synchronous adjustment to the base station to be adjusted. The base station to adjusted adjusts its own 5ms frames and eliminates synchronous deviations in compliance with parameters of the synchronous adjustment command. The present invention increases promptness of synchronization problem discovery, reduces maintenance workload and improves network call quality.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for synchronous monitoring of base stations in a wireless communication system. Background technique [0002] The air interface of wireless systems such as TD-SCDMA and PHS adopts the working mode of TDMA / TDD (Time Division Multiple Access / Time Division Duplex). Such a system must have precise air frame synchronization to ensure that the signals sent by each mobile terminal will not overlap or be misplaced at the base station, so as to avoid interference of wireless time slots and ensure efficient use of wireless resources. Air frame synchronization has a huge impact on network performance. Poor synchronization can lead to a series of problems such as ineffective operation of base station channels, no paging response in the system, decreased penetration rate of base station cells, and easy call drop during handover. [0003] For the air frame synchronizat...
