System and process for determining when a radio telecommunications network is to switch between a first degree of service and a second service level based on a highly accurate estimateAnd reliable bit error rate and the process to estimate error rates of bits of upper and lower connection link in a telecommunications network of radio. A system for determining when a radio telecommunications network should switch between a first degree of service and a second service level based on a highly accurate estimation and conReliable bit error rate BER.The system estimates (65) ber on a link the upper and a lower connection on a channel of the user.(66) and determines if the BER on the link the upper and the lower connection on the channel of the user are below a first placement of thresholds.The system then measures the SFET rber and the rate of erasure of ERF group on the superior binding of voice channel, and determines (74) if the BER link below.The rber connecting upper and fer of superior binding are smaller than a second threshold values.If smaller, the system sends and receives a data message on a control channel associated with fast (FACCH).The system obtains a highly accurate estimate (83) of BER on a link below on the channel FACCH,And reports (88) ber link below in a message on the link above the channel FACCH. The system then estimates the BER on the link above the channel FACCH.Finally,The system switches the radio telecommunications network in the first grade of service for the second grade of service in response to a determination that the BER of upper and lower connection link on theFACCH channel are below a third placing of thresholds.
