Problems solved by technology

When congestion occurs, the RNC sends a transmission congestion indication to the NodeB, and the NodeB controls the congestion of the Iub interface by discarding uplink transmission frames or scheduling UE power authorization, but the response time of the Iub interface transmission bandwidth congestion Long, and will lose signaling and data due to congestion

Abstract

The invention discloses a method and a device for congestion detection and flow control of an uplink. The method for congestion detection and flow control of the uplink comprises that: step S202, actual flow of a current transmission network port is measured periodically on a B side of a wireless network node, and the actual flow obtained by the measurement and total available bandwidth are sent to a high-speed uplink packet access scheduler together; and step S204, the high-speed uplink packet access scheduler calculates bandwidth occupation rate by utilizing the received actual flow and the total available bandwidth, and adjusts scheduling authorization of a user mobile terminal according to the bandwidth occupation rate. The method and the device greatly shorten the time of responding and processing the congestion of Iub interface transmission bandwidth, and reduce the loss of signals and data caused by the congestion.

Description

technical field [0001] The invention relates to a method and equipment for uplink congestion detection and flow control in a wireless access network of a telecommunication system. More specifically, the present invention relates to an uplink congestion detection and flow control method and device for an Iub interface of a Universal Mobile Telecommunications System (UMTS) radio access network. Background technique [0002] A UMTS mobile network can be divided into several major components, including one or more core networks (CN) responsible for establishing and controlling user sessions, and a UMTS terrestrial radio access network (UMTS terrestrial radioaccess network) that controls access to the air interface. network, referred to as UTRAN). figure 1 The architecture of UTRAN is shown in . [0003] The interface between the UTRAN and a user mobile terminal (user equipment, referred to as UE) is provided by a wireless network Node B (hereinafter referred to as Node B). Th...
