Abstract

The invention discloses a method and a device of controlling network congestion. The method includes that an access network transmits an extended access barring (EAB) parameter and information indicating an application range of the EAB parameter to user equipment, wherein the information indicating the application range of the EAB parameter is used for indicating the user equipment whether to carry out EAB operation before connection is established between the user equipment and the access network or not, or used for indicating the user equipment whether to carry out the EAB operation before connection is established between the user equipment and the access network and between the user equipment and a core network or not, and the EAB parameter is used for carrying out the EAB operation when the need for carrying out the EAB operation is confirmed by the user equipment. The method and the device of controlling the network congestion can control terminals to carry out the EAB operation in a targeted mode and relieve the network congestion when the network congestion occurs. Meanwhile, signaling connection establishment processes initiated by the terminals can be limited, so that the aggravated congestion is avoided and the method and the device of controlling the network congestion can be matched with the EAB operation to relieve the congestion of the core network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for controlling network congestion. Background technique [0002] In today's society, with the continuous improvement of people's living standards, people's demand for communication is also increasing. Along with the growing variety of communication needs, wireless communication technology is also developing rapidly. New technologies emerge in an endless stream, which can be described as changing with each passing day. The fastest and most eye-catching is undoubtedly the Internet of Things technology. [0003] The Internet of Things technology mainly completes the communication between machines. Therefore, in the 3GPP meeting, the Internet of Things was approved as "Machine Type Communication", or MTC for short. With the introduction of the concept of the Internet of Things, communication has been extended to all aspects of social life, such as smart ho...
