decision however the preference value of access technology a 3 is negative u2212 5 and indicates that further allocation of communication flows to the access technology would have an adverse effect on system performance also a third access technology a 5 is included in memory together with an associated preference value 1 in the example of fig1 communication flow f 1 is allocated to access technology a 1 allocation of communication flow f 1 to access technology a 1 has an adverse effect on allocation of future communication flows to access technology a 3 due to interference rendering the preference value of access technology a 3 negative u2212 5 allocation of communication flow f 1 to access technology a 1 also affects a third access technology a 5 and affects another communication flow f 3 allocated to a 5 this impact is included in the memory represented by the table as a related flow in a flow bundle by inclusion of related flows in bundles as illustrated in the example in fig1 a plurality of flows in a flow bundle can be considered the stored preference values such as the one illustrated in the table of fig1 consequently comprises a number of entries according to the first example embodiment as illustrated in fig1 there is one entry for each access technology that is available for assignment of future communication flows according to example embodiments described in further detail below more than one entry for each access technology is not excluded if an allocation selection decision is such that there is still a preference of using the allocated access technology also for future allocations of communication flows the preference value is positive the greater the positive value the greater is the preference if an allocation selection.
