Abstract:
A receiving and storing means (1) for transmission units (TRU) containing information, each transmission unit having a format such that it contains a plurality of unit property fields (10-14) that each contain a value associated with a property of said transmission unit, comprising:storage means (2) for storing transmission units, said storage means being arranged such that any transmission unit stored therein is allocated to one or more of a plurality of predetermined groups (G.sub.1, G.sub.2, . . . , G.sub.n ; i),data determination means (3) arranged such thatthe respective values in a predetermined number of unit property fields of a transmission unit received by said receiving means are determined, and,for certain groups of said storage means, corresponding values in the same predetermined number of unit property fields of all transmission units in said certain groups are determined,comparison means (4) for comparing said values from said received transmission unit with the values from said transmission units contained in said certain groups,comparison evaluation means (5) arranged such that, for each of said certain groups, the number of times (O.sub.ji) is counted that a value from a specific unit property field (j) of said received transmission unit occurs in the same specific unit property field (j) of transmission units stored in said group (i), to thereby determine a value occurrence value (O.sub.ji) for said same specific unit property field (j) of said group (i),calculation means (6) arranged such thateach value occurrence value (O.sub.ji) for a given unit property field (j) and given group (i) is multiplied with a multiplication factor (W.sub.ji) that depends on said given unit property field (j) and said given group (i), to thereby calculate a number of group product values that are equal in number to said predetermined number of unit property fields, and,for each of said certain groups, said group product values are added together to a sum, said sum being divided by the number (n.sub.i) of transmission units in said group (i), to thereby generate a storage decision value (S.sub.i) for each of said certain groups, andstorage decision means (7) for deciding in which of all groups of said storage means to store said received transmission unit, on the basis of said storage decision values (S.sub.i) of said certain groups.
