GSM Exchange Wireless Network Optimization

This article separately narrated the system optimized process from the MSC, BSC two aspects.In view of MSC this suboptimization, has collected the massive statistical data, has done the massive work. Enable the network quality to have further enhanced. This suboptimization primary mission is: 1st, improves the network quality stably 2, the maintenance system 3, the standard bureau data 4, in view of the network development, proposes the rationalization proposal. The network optimizes mainly through analyzes the STS telephone traffic to count and traces the EOS code to discover and to solve the question which in the network exists. Simultaneously also to the B table, the RC table, the E table, the GT table, the route data, the SAE definition and so on each game of data carries on the thorough inspection and the optimization. Mainly has completed following work: Comprehensively reorganized in the switchboard each kind of data establishment, eliminates the garbage, Including B number analytical table data, route definition data, RC definition data, E table, FORLOPP, SYSTEM RECORY, SAE establishment, recording notice data and so on. Analyzes in the network system comprehensively each target, the research influence target various aspects parameter establishment. Seeks in the network to be possible to carry on optimized the part, analyzes and the adjustment.CP load analysis. The adjustment switchboard attribute, the extension network paging time, enhances the paging success ratio.Inspection switchboard bureau data establishment, including B analytical table, route data, GT analysis data and so on. Collects TOP20 EOS, carries on the tracing analysis one by one, classifies, discovers its production reason diligently, and seeks as far as possible the reasonable processing method. Standard sound recording notice content.Guaranteed exterior plot data timeliness and the uniformity, enhance between the bureau to cut the success ratio. Carries on the inspection and the reasonable disposition to the system SAE establishment.To enhances the network system target to put forward some long-term proposals, including: The promotion pronunciation mailbox and the call waited for the function the promoted use, enhances the exchange system call completing rate and the voice call completing rate. Between the solution bureau the signaling coordination question, enhances the exchange system call completing rate and the voice call completing rate. Inspection transmission quality, solution transmission error code, rear sight slide question.The increase network cover, reduces EOS400 the number of times.Increases MSC to the CCHLR signaling link, reduces the signaling load.In BSC entire optimized process. Key places enhances the system inspection target and in the analysis solution network existence question. Carried on the massive roads to measure the work, through analyzed the road to measure the document, carried on the network parameter the revision, the improvement wireless network performance.The optimized prime task is every day collects and analyzes the BSC busy time statistical data, found the problem and performs to solve as soon as possible. The inspection frequency plans and makes certain adjustment; Every day carries on the parallel shot, and revises the discovery the mistake and the unreasonable parameter establishment. Collects and inspects BSC CDD, in which certain dispositions and the parameter is adjusted uses to improve the wireless network performance. Has discovered several plot days stitch binding instead; Has carried on the dilatancy to 13 plots and so on.Carries on the concrete work is as follows: Every day collects and analyzes BSC the STS statistical data, the analysis performance index; Every day collects BSC the plot parameter, carries on the parallel shot; Confirmed the base depot the geographical position, discovered is inconsistent by 1 base depot position database with the physical location;Inspects each plot through NCS the neighbouring area relations, added more than 500 opposite neighbours plot relations according to the NCS result and the actual situation, deleted 300 to the unnecessary cut relations; Revises BCCH frequency 13 with TCH frequency 29, 124 BSIC; Revises 15 plots and the synthesizer frequency-hopping alters to the baseband frequency-hopping; In order to improve on the downward disturbance to adjust the dynamic merit to control the parameter and with the wireless performance correlation plot parameter; Has carried on the dilatancy to 13 plots; The adjustment parameter alleviates TCH and the SDCCH jam; Has discovered the base depot day stitch binding instead; Analysis processing question plot.
