METHOD OF EXTERNAL QUALITY CONTROL OF COMMUNICATION SERVICES PROVIDED BY NETWORK Russian patent published in 2018 - IPC G06N5/00 H04W52/20 H04B7/05 

FIELD: communication equipment.

SUBSTANCE: invention relates to communication equipment. Method of external quality control of the services provided by the communication network consists in setting measurement object; transmitting and receiving pulse sequence; detecting bit errors; counting their number; setting additional initial data: pairs of correspondent subscribers; test sequence known to a given pair of subscribers consisting of K bits, the required probability of a bit error (P_err); periodicity (T_me) of measuring the probability of a bit error (P_err) at the maximum transmission rate (V_{max tr}); in a continuously functioning network, under real operating conditions, transmitting and receiving test sequence between a pair of correspondent subscribers at the maximum transmission rate (V_{max tr}); calculating probability of a bit error (P_err) of the test sequence; memorizing in the matrix (M) their probability values in the information direction; compare values of the required bit error probability (P_{err re}) with bit error probability values (P_err) of the test sequence and form a signal confirming the quality of the communication services provided.

EFFECT: increased reliability of information on the quality of the communication services provided.
