Access network congestion control method, base station device, and policy and billing rule function network element

摘要

An access network congestion control method, a base station device, and a policy and billing rule functional network element are provided. The method includes the following steps: information about user equipment in a congested state among at least one user equipment, information about user equipment in an over-served state among at least one user equipment, - sending (S101) a congestion report to the policy and billing rule function network element (PCRF) containing information about the radio frequency resources occupied by the user equipment in the served state (S101) (S102), and performing a radio frequency resource adjustment policy for user equipment in a congested state and user equipment in an over-served state (S103). A corresponding base station apparatus and PCRF are further disclosed. According to embodiments of the present invention, when congestion occurs in the radio access network, the radio frequency resources of the user equipment in congested state and the over-served state of the user equipment are reallocated to ensure smooth communication .
