Realizing method for estimating public telephone exchange network performance

Abstract

A method for evaluating exchange network performance of public telephone includes obtaining various network structure parameters and network resource utilization parameters in PSTN of public telephone exchange network then automatically calculating out various network safety index and resource utilization rate index according to obtained various parameters for carrying out confirmation of PSTN network performance.

Description

technical field [0001] The invention relates to the technical field of communication network evaluation, in particular to a method for evaluating PSTN (Public Switched Telephone Network) performance. Background technique [0002] At present, operators have built more than 300 PSTN local networks, more than 10,000 switch offices, and 354 million switch lines across the country. However, the construction mode of each PSTN network is relatively extensive, and most of the local network structures are complex. There are also various models in the network, and some of the devices in the network have a long lifespan, so the aging of the devices is serious. Obviously, these aging devices cannot bear the increasing amount of communication business processing, resulting in the decline of the communication capability of the entire network, and thus unable to meet people's communication needs. Moreover, each operator does not have a macroscopic understanding of the aging of the equipme...

AI Technical Summary

Problems solved by technology

[0006] (1) The daily maintenance data and the corresponding evaluation indicators are some "lag" indicators. Taking the failure rate as an example, this indicator indicates the measurement of the failure of the network before that, and it cannot be expected that the network may occur in the subsequent period of time. The failure rate of this index is not very meaningful for the guidance of network optimization and improvement in advance

[0007] (2) The number of evaluation indicators based on daily maintenance data is relatively small, and due to the complexity of the communication network, each link has a certain inherent failure rate, which makes each indicator unsystematic and uncontrollable, making it impossible for maintenance personnel to control "Lagging" Failure Rate Metrics

[0011] (1) The content of the evaluation is narrow, and only the individual equipment of the end office or tandem office of the local fixed model is evaluated, and other models cannot be evaluated, and the entire local network cannot be evaluated;

[0012] (2) It is necessary to manually collect and analyze data for each end office one by one, which is time-consuming, laborious and costly;

[0013] (3) Only the evaluation of single board failure and resource allocation of its own equipment is added, so there are still shortcomings of few evaluation indicators and no quantification

[0014] To sum up, there is currently no scientific and reasonable PSTN network evaluation solution that can ensure that network operators can fully understand the network status and make reasonable optimization, transformation and adjustment of the network.
