Description

Fusion type network management realization method and system for grid management
Technical Field
The invention relates to a fusion type network management system, in particular to a grid operation and maintenance management and evaluation system of a cable television network.
Background
The broadcast television network has developed cable broadband and interactive bidirectional service for many years, and the CMTS access technology, referred to as a large C network for short, is commonly adopted. The bidirectional service has high requirement on network quality, complex maintenance and unstable fault point, and particularly has the feeling of blind feeling for maintenance personnel. The HFC network user distribution network is a centralized distribution structure, and the downlink is a broadcast distribution type, so that the HFC network user distribution network has the characteristics of simple line and low cost; the uplink is of a multipoint convergent type, and interference superposition forms funnel noise. Namely, the noise problem is inherent in the large C network technology, in the actual maintenance, in order to strengthen the personnel assessment and the service expansion, a gridding operation and maintenance mode is generally implemented, and the fault correlation among the large C networks brings difficulty to the assessment.
In order to improve the network transmission quality, the existing economic and feasible method adopts the C-Docssis technology to optimize the network, namely the small C technology, so that the corresponding network evaluation method and fault reporting display need to be correspondingly improved.
The maintenance quality assessment has many subjective factors, and is difficult to be customized, and the individual places use the call for repair as the assessment basis and are indirect assessment means, so that the accuracy and the justice are difficult to be achieved, and the technical staff cannot be encouraged to actively investigate, eliminate faults and research the technology. The existing examination is difficult to deal with the fierce broadband competitive market.
In order to obtain accurate user perception, in the prior art, subjective questionnaires, call visits and other modes are generally adopted; the subjective questionnaire mode obtains relatively accurate results, but the final results have a large relationship with the number and distribution of the sampling samples, and the operation process is complex and the cost is high. The same problem exists in call return visit, which directly causes maintenance delay and has high customer complaint rate. Especially, the level evaluation of the overall network quality cannot provide objective reference for high-level leaders.

if the emission level is a normal value, the deviation is 0;
level deviation exists, and three-level alarm is defined;
the poll calculates the next CM.
Further, the carrier-to-noise ratio deviation value is calculated as follows:
