CONTROLLING PACKET FILTER INSTALLATION IN A USER EQUIPMENT

摘要

A communication system includes a user equipment (UE) 10 and a gateway 26.The UE (10) sends data packets on one or more bearers (52, 54) to the gateway 26. One or more packet filters (62, 64) are installed in the UE (10) for associating the data packets with the bearers (52, 54). A decision is performed if installation of a new packet filter (62, 64) in the UE (10) is required to map the data packets of indicated data traffic to a particular bearer (52, 54). The result of the decision may then be indicated from a policy controller (30) to a gateway (26) and/or from the gateway (26) to the UE (10). Depending on the result of the decision, the gateway may initiate signaling of the new packet filter (62, 64) to the UE (10) and/or the UE (10) may install the new packet filter (62, 64).
