Abstract: Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

Abstract: A method of bearer deletion is provided to improve the universality of the bearer deletion process. The method includes: receiving, by the original intermediate NE, the cancellation type indication parameter sent by the HSS, and deleting the bearer between the serving gateway (S-GW) and a packet data network gateway (P-GW), if the original intermediate network element obtains an attach type according to the cancellation type indication parameter indicating an attach type and a corresponding bearer exists on the original intermediate NE. This method helps efficiently improve the universality of the bearer deletion flow.

Abstract: A controller is configured to: obtain a state of each of a plurality of queues of a network node; determine, based on the states of the queues, whether the utilization of one or more queues exceeds one or more thresholds; generate one or more new entries for a gate control list of the network node that controls the plurality of queues, if one or more thresholds are exceeded; and provide the one or more new entries to the network node. Further, a network node is configured to provide a state of each of a plurality of queues to a controller, and obtain one or more new entries for a gate control list of the network node that controls the plurality of queues, from the controller.
