External packets entering a transmitting entity (SS1...SSn, BS) of a broadband wireless access system are forwarded to a receiving entity onto MAC layer connections (CID1...CID3) at the air interface between such entities in a manner depending on the result of a packet classification (103, 106) performed by using a set of classification rules identified by a rule index and associated with a priority index determining the order of application of different rules to packets relating to a same service. The classification rules (100) include both classification rules specific for data communication protocols and containing one or more protocol-specific parameters to be matched by corresponding fields in a packet being classified, and a pass-through classification rule only containing a priority index and a rule index, but no protocol-specific matching parameter, said pass through classification rule being applied to packet having matched no protocol-specific classification rule. |
