Abstract: Embodiments of the present invention disclose a system message notification method and user equipment, and relate to the field of communications technologies. The method includes: receiving, by a radio resource control layer of user equipment, a network configuration message sent by a network side, where the network configuration message includes a data service access control parameter; and when a value of the data service access control parameter is 0, sending, by the radio resource control layer, a first notification message to a non-access stratum of the user equipment, where the first notification message is used to indicate that the user equipment is barred from accessing a data service. In the embodiments, a user is notified immediately after a message indicating that the data service is barred is received, so that the user can correctly perform a data service connection operation.

Abstract: A packet processing method, a forwarding device, and a packet processing system are applied to a switch, a router, or another device or system in which a control plane and a forwarding plane are separated. In the packet processing method, the forwarding device obtains a first forwarding table that corresponds to a first packet and that is configured by a control device, where the first forwarding table includes at least one data structure, and the at least one data structure includes a field value type and content corresponding to the field value type. Then, the forwarding device processes the first packet based on a field value type in the at least one data structure and content corresponding to the field value type, to obtain a field value of a field value type. Therefore, packet processing efficiency is improved.
