Problems solved by technology

If the algorithm setting is too harsh, it will lead to irreversible call drop that should be saved; but if the setting is loose, it may also lead to the second situation above. The user of terminal B cannot bear the voice quality of terminal A and actively hangs up. Network optimization It is also difficult for personnel to analyze problem areas from statistical indicators, and it is impossible to carry out targeted optimization measures

Embodiment Construction

[0039] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0040] In the voice service provided by the CDMA base station system, there are usually two characteristics of the deterioration of the uplink signal (reverse signal). One is that the base station system receives more error frames or no frames, and the other is that the base station system may be longer The time cannot receive the reverse signaling from the terminal. Considering these two features, the present invention can add the monitoring operation of the reverse error data rate and reverse signaling in the monitoring process, and cooperate with the existing reverse call drop judgment algorithm to realize the impact on the voice quality of the uplink signal quality problem The monitoring of two situations that lead to abnormal release.

[0041] An embodiment of the present invention provides a process for monitori...

Abstract

The invention relates to a method for monitoring voice service abnormal release events, comprising: after a base station system sends an instruction or a forward release order which requires a first terminal to response to the first terminal, the base station system starts a reverse voice quality adjusting algorithm to adjust whether the reverse voice quality accords to the condition of abnormal release, if yes, the first terminal is recorded abnormal release. The invention adds a step of adjusting whether the call meets the problem existed in reverse voice quality in the monitoring process ofvoice service abnormal release events, which guarantees the monitor of the second abnormal release event without modifying the prior reverse drop-call adjusting algorithm and parameters, and preventsinaccuracy caused by inappropriate parameter setting and possibility of reducing drop-call.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a monitoring method and a monitoring system for an abnormal voice service release event in a wireless communication system. Background technique [0002] In a wireless communication system, the terminal communicates with the base station through uplink and downlink signals. The signal sent by the terminal to the base station is called an uplink signal or reverse signal, and the signal sent by the base station to the terminal is called a downlink signal or forward signal. The uplink signal sent by the terminal needs to overcome noise, internal and external interference, link loss, and equipment loss to reach the base station. At this time, the signal quality must reach or exceed the demodulation threshold of the base station to be successfully demodulated by the base station. [0003] Take the terminal call in the CDMA network as an example. CDMA terminal A and terminal B ar...
