The Effect of Radio Link Time out on the Mobile Networks Performance

This research is an evaluation study of the changing parameter radio link time out and describes the results of the trial by changing parameters of mobile channel such as radio link time out downlink and uplink and the corresponding effect on the performance stats and mobile channel quality. The idea of changing RLINK parameters is to extend the duration of the calls in bad coverage conditions or high interference before losing the call connection. In areas with quality problems and low signal, calls will have more possibilities to avoid a call drop due to bad quality. Parameters RLINKT and RLINKUP were changed from 16 to 24 in PLBSC1, PLBSC2 and OXBSC1. The outcome of the trial showed good results. It has been proved good improvement in traffic drop rate results despite a slight increase in the SQI values.
