A method of processing information in a wireless communication network, the method comprising the steps of: - receiving (S1, 502, 504) a signal encoded with a convolutional code, wherein the encoded signal comprises a user terminal identifier, information and a check value and wherein the received signal is represented by soft bits; - partially decoding (S3, 508, 510) the encoded signal using a Viterbi algorithm to derive the information and the check value, wherein the partial decoding includes computing a Viterbi state metric (Λ) and wherein the decoding of the encoded signal uses a partial Viterbi algorithm interrupted depending on a reliability parameter Λ path state; Λ path iterate prior to a trace-back process; - deriving (S4, 512) the reliability parameter Λ path state; Λ path iterate based on the Viterbi state metric (Λ) of a partial Viterbi path, wherein the reliability parameter Λ path state; Λ path iterate is computed by a summation including the soft bits, wherein the reliability parameter is a Viterbi path metric; - deriving (S4, 512) a reference value (Γ) based on the received encoded signal, wherein the reference value (Γ) is determined by summation of absolute values of the soft bits in the received encoded signal; - deriving (S4, 512) a second reliability parameter as a function of the derived reliability parameter and the reference value (Γ), wherein the second reliability parameter is a homogeneous function of degree zero which provides a relative reliability measure depending on both the derived reliability parameter and the reference value (Γ); and - selectively processing (S5, 514, 516, 518) the information depending on the check value, the second reliability parameter, and the reference value (r), wherein it is determined if the second reliability parameter fails to fulfil a predefined reliability criterion (R TH) or the reference value (Γ) is smaller than a predefined reference threshold (Γ TH), and if so, the information is discarded, and if not so, the process proceeds to matching the check value against an identifier of the user terminal identifier. - receiving (S1, 502, 504) a signal encoded with a convolutional code, wherein the encoded signal comprises a user terminal identifier, information and a check value and wherein the received signal is represented by soft bits; - partially decoding (S3, 508, 510) the encoded signal using a Viterbi algorithm to derive the information and the check value, wherein the partial decoding includes computing a Viterbi state metric (Λ) and wherein the decoding of the encoded signal uses a partial Viterbi algorithm interrupted depending on a reliability parameter Λ path state; Λ path iterate prior to a trace-back process; - deriving (S4, 512) the reliability parameter Λ path state; Λ path iterate based on the Viterbi state metric (Λ) of a partial Viterbi path, wherein the reliability parameter Λ path state; Λ path iterate is computed by a summation including the soft bits, wherein the reliability parameter is a Viterbi path metric; - deriving (S4, 512) a reference value (Γ) based on the received encoded signal, wherein the reference value (Γ) is determined by summation of absolute values of the soft bits in the received encoded signal; - deriving (S4, 512) a second reliability parameter as a function of the derived reliability parameter and the reference value (Γ), wherein the second reliability parameter is a homogeneous function of degree zero which provides a relative reliability measure depending on both the derived reliability parameter and the reference value (Γ); and - selectively processing (S5, 514, 516, 518) the information depending on the check value, the second reliability parameter, and the reference value (r), wherein it is determined if the second reliability parameter fails to fulfil a predefined reliability criterion (R TH) or the reference value (Γ) is smaller than a predefined reference threshold (Γ TH), and if so, the information is discarded, and if not so, the process proceeds to matching the check value against an identifier of the user terminal identifier.
