Description
Technical field
The present invention relates to communication network assessment technology field, relate in particular to a kind of implementation method of assessment PSTN (public switched telephone network (PSTN)) performance.
Background technology
At present, each operator has built together into more than 300 PSTN local networks throughout the country, has surpassed ten thousand institutes of switch office, switch line number reaches 3.54 hundred million, but the construction mode of each PSTN net is more extensive, most of local network complicated network structures.Type in the network also is how each is various, and the part in the network is longer at the net equipment time limit, thereby the ageing equipment situation is comparatively serious.These aging equipment obviously can't bear growing communication service processing amount, cause the communication capacity of whole network to descend, and then can't satisfy people's communication requirement.And each operator is to not understandings of a macroscopic view such as the aging conditions of equipment, thereby also just can't reasonably adjust planning to putting in order net.In addition, existing network lacks unified rational planning too at aspects such as resource utilization, network security, operation costs, makes each operator can't reasonably use existing network best service is provided.
In order effectively to improve the above-mentioned operation management present situation of PSTN network, each fixed line carrier urgently wishes to grasp the integral status of network.Simultaneously, in order to optimize self network, cut operating costs, improve network service quality, bring into play self network advantages, thereby obtain big benefit with few input, improve the competitiveness of self, the same urgent hope of each fixed line carrier can be understood self network condition comparatively all sidedly.In a word, each operator has only accurately understands self network advantages, inferior position, bottleneck, hidden danger meticulously, can reasonably improve network targetedly.For this reason, each operator just needs local network is carried out network evaluation, and according to assessment result, and the target of different phase, constantly local network is carried out the network optimization rationally and effectively and improve.
At present, some operators analyze, assess network according to the regular maintenance data, and the analysis and evaluation scope can not exceed the regular maintenance data of operator.Usually, the regular maintenance data of operator comprise: telephone traffic, call completing rate, failure rate, relaying occupancy etc.The evaluation index that each operator adopts then is an existing index in GB and the telecommunications service regulations, comprising: MTTR (Mean Time To Repair), network availability factor, year equipment failure rate, telephone traffic, call completing rate, failure rate, relaying occupancy or the like.
Only self network is carried out the mode of analysis and evaluation for operator according to the regular maintenance data because the regular maintenance data characteristic, determined this analysis and evaluation mode will exist below the shortcoming of two aspects:
(1) described regular maintenance data and corresponding evaluation index all are the indexs of " hysteresis ", with the failure rate is example, this dial gauge is shown in measuring that network breaks down before this, and can't be expected at the failure rate that follow-up time section network may occur, this index is not very big to carrying out the improved directive significance of the network optimization in advance.
(2) described evaluation index negligible amounts based on the regular maintenance data, and because communication network complexity, each link all has certain inherent failure rate, thereby makes each index have not system, uncontrollable characteristics, makes attendant's's uncontrollable " hysteresis " failure rate index.
As can be seen, the shortcoming of above-mentioned two aspects will make that in the use of reality these indexs can't instruct the attendant to optimize network so that index is adjusted to desired value.
In addition, in the above-mentioned indication, the corresponding quantization index is not set, just makes the security performance aspect of network to be understood yet by the management maintenance personnel for aspects such as system safety, certainly also just can't adjust, to satisfy the corresponding communication demand to the safety measure that adopts.
At present, a kind of PSTN network optimization solution has also been proposed, specifically be that evaluating and optimizing of aspects such as relay resource aspect, single board default carried out in the switch office point of local fixing machine type, but can not other type be assessed, also just can't assess certainly whole net.Therefore, this scheme exists corresponding shortcoming equally:
(1) the assessment content is narrow, only end office (EO) or tandem exchange's individual equipment of local fixing machine type is assessed, and can not do assessment to other type, can not assess whole local network;
(2) need manually one by one each end office (EO) to be carried out data acquisition, data analysis etc., time-consuming, effort, and cost height;
(3) only increase the assessment of equipment of itself single board default and resource allocation, thereby still existed evaluation index few, and do not had the shortcoming of quantification.
In sum, also do not have a kind of scientific and rational PSTN network evaluation scheme can guarantee Virtual network operator awareness network situation all sidedly at present, and network is reasonably optimized transformation adjustment.
