RxLevAccessMin This is the minimum signal level required by the mobile to access the cell (normally a signal level close to –100 dBm is required). RxLev is compared to RxLevAccessMin and if it is lower, then it keeps on searching for another BCCH. It is the limiting factor in the downlink direction. MSTxPower and MSTxPowerMax The MSTxPower parameter is related to the maximum power MS that can be used on network parameter settings. It is a limiting factor in the uplink direction and cell size. Based on the type and class, MSTxPower is the maximum transmission power of the mobile station.
The inputs from the drive tests and network management systems are used in the software to calculate new values for the parameters. The performance assessment is based on three factors: coverage, traffic and quality and the amount of traffic and blocking; resource availability and access measurements; handover measurements, receiver levels and power control measurements. Once the measurements and analysis are carried out, the process of optimizing the network begins by tuning the parameters. 1 Dimensioning The main aspects of dimensioning in a transmission network are to plan the capacity of the BTS–BSC and BSC–MSC transmission links.
Plus the whole network quality could be well perceived by the subscriber based on the experience of using/talking on his/her mobile. , ranging from a few dollars to thousands of dollars.
