The present invention relates to a solution for handling deferred leg linking in policy and charging rules function in a telecommunications network in relation to handover between two different access technologies. The electronic devices communicate wirelessly with the security control system. By this, an operator can select the degree of aggressiveness of the transmission. The second set of feedholes extends through the die body from the inlet end to the outlet end. The invention may be embodied as devices and methods. The method may also include receiving a rule modification for the filter, the rule modification including at least one input as a range of values, and performing a check for conflicts of the rule modification with the rule in the filter.
