<p>Embodiments of the present invention provide a method and an apparatus for performing policy control on a data packet. The method mainly includes: allocating, by a local gateway, a port range to a UE, where the port range is unique to the UE; sending, by the local gateway, the port range of the UE and user information to a policy server, so that the policy server makes a policy rule for the UE, where the policy rule contains the port range; and performing, by the local gateway, network address translation on a packet sent by the UE , so that a source port of the converted packet is in the port range, and sending the converted packet to a network gateway in a fixed network, so that the network gateway performs policy control on the packet according to the policy rule received from the policy server. The embodiments of the present invention may enable the network gateway to identify the UE according to the port range and perform policy control on the UE according to the policy rule containing the port range, so as to implement differentiated processing on different UEs and improve user experience.</p> |
