Improve GSM Network Call Drop by RF Optimization
All GSM Service Provider uses KPI (Key Performance Indicator) to monitor their quality of service (QOS) Performance. Nowadays major issue is call drop in GSM. So if optimization major issue is call drop in GSM. So RF optimization and drive test is tool to find reason of call drop. To improve the the performance of the service provide. In this research paper some practical cases and solutions are adopted to reduce the call and increase the customer and profit of the service. Majo r parameters Rxlevel, Handover failuer, Rxquality, C/A worst, etc. Drive test tool Ascom TEMS 16.3.1 and analyser mapinfo 9.3 used to perform drive test and analyse log files recoded in TEMS to find problem and give the si\olution of call drop. In addtion the RF drive test simu lation results is attached which can clearly shows that call drop id reduced and imrovement in the parameter
The radio has been a large-scale development in recent years, with the advent of GSM (Global System for Mobile Communications) mobile phone. This growth is primarily due to the emergence of internationally accepted standards which facilitated the large-scale deployment, and also control technologies involving telecommunications, electronics and computers. Deploy these networks has been a great challenge for operators who have to master radio waves to completely new applications in relation to what was done since the beginning of the century. We went from broadcasting, personalized information and requirements for quality of service. On both issues, operators have made enormous progress in research on methods and planning tools that incorporate such models radio wave propagation, models for estimating quality of service and optimization algorithms on the setting.
A Practical Approach of Planning and Optimization for Efficient Usage of GSM Network
Planning of wireless networks is vital if operators wish to make full use of the existing investments. This paper deals with a practical approach of radio network planning process for efficient usage of GSM network. The key performance indicator (KPI) and drive test report of a Bangladeshi operator " Teletalk Bangladesh Limited " are used to make proposals on how operators can optimize radio resources as well as provide the required QoS to the subscribers. This study would help to plan operators to enhance coverage, improve quality and increase capacity in the days to come.
Analyzing the Signal Flow and RF Planning in GSM Network
RNS (Radio Network Subsystem) is one of the important subsystem in GSM (Global System for Mobile communication) architecture. It connects the mobile user to the GSM backbone for switching. This project involves in a study on the functions carried out by each part of the system and how the nodes or equipments involved in GSM Radio network are connected to each other designing of air interface in GSM is one of the vital parts in GSM planning. This project involves in a study of how the air interface in mobile environment is planned and engineered.
Frequency planning in GSM mobile
… and Computers in …, 2008
GSM mobile system like other communication systems has the frequency band used in the systems depends on the type of the GSM system, cellular system means dividing the area region the system installed in it in to many cells, each cell and each channel must has it's own frequency, so the frequency planning is very important to the future of the system installed because of continuously expanding the area of each city and increasing the users of GSM system, the frequency band for the system is limited, so it must be taken account the number of frequencies using, in this paper, frequency planning before installing the system has been studied and the advantages of this process for system future installed in that area.
Day after day, the number of mobile users, data rates and mobility has increased a lot. This increased the demand for LTE technology. A mobile network is expected to provide uninterrupted and good Quality of Service (QoS) to a user equipment (UE). In the first stage, the location of stations in the target region is determined and applied by planners. Then, a frequency is assigned for each cell. Frequency number is used repeatedly in mobile operators because it is limited. However, such situations result in interference that decreases the network quality. Also, mistakes made by planners reduce the Key Performance Indicators (KPI) of the mobile operator. That's why mobile vendors insist on making optimizations to improve these parameters. In this paper, an effective and fast optimization technique is obtained for solving network quality problems at 900 MHz. These techniques have been applied in the area serving a specific region and the effects of the optimization study on the sites have been determined. As a result, the Call Setup Success Rate (CSSR) is increased from 89.55% to 89.86%. Both Drop Call Rate and Total Call Block are decreased from 16 to 14. Also, the Handover Success Rate (HSSR) is reduced from 97.54% to 97.72%.
RADIO FREQUENCY OPTIMIZATION OF MOBILE NETWORKS IN ABEOKUTA, NIGERIA FOR IMPROVED QUALITY OF SERVICE
Radio Frequency Optimization is an important process in verifying and monitoring the performance of any GSM radio network already deployed in an area. It is a periodic activity that is done to maintain a good radio quality of service and enhance end users' perception. This research work aimed at improving the Quality of Service (QoS) of the GSM radio network deployed within Abeokuta City, Nigeria in order to retain existing subscribers and attract new ones while continually expanding the network. A drive test was carried out in dedicated mode with the goal of collecting measurement data as a function of location and to identify the eventual black spots in the GSM radio network. The data collected were analysed in post-processing software tool (MapInfo Professional) to identify the causes of problems and determine how these problems can be solved effectively and efficiently. Poor network coverage and degradation in QoS were encountered in some parts of the city. This performance was due to the land topology and the presence of physical obstructions in the propagation environment. The Hand-Over (HO) failures were mainly due to Base Station Controller (BSC) synchronization issue. Therefore, additional Base Stations were planned to be deployed in those areas; and the BSC synchronization issue was resolved. This will resolve frequent network complaints that lead to customers' dissatisfaction and boost the revenue of the mobile network provider.
