FIELD: information technology.
SUBSTANCE: PAN field is included in a data block and indicates one of reception acknowledgement (ACK) or reception non-acknowledgement (NACK) for a specific temporary block flow (TBF) between a mobile station and a network. Data block which includes encoded bits of the PAN field and PAN check sequences (PCS) is received. The encoded bits of thee PAN field and PCS are decoded. PCS checking is performed with the PAN field and PCS. Soft metric is checked by comparing soft metric calculated during decoding with a threshold value and a PAN field is accepted if PCS checking and soft metric checking are successful.
EFFECT: low of probability of false acceptance of erroneous PAN fields.
