Method and device for controlling rate of enhanced uplink dedicated channel service

Abstract

The invention discloses a method and a device for controlling the rate of an enhanced uplink dedicated channel service. The method comprises the steps of: configuring a maximum bit rate threshold of the enhanced uplink dedicated channel service on a network element interface; judging if the initial rate of the enhanced uplink dedicated channel service loaded on a wireless link passing through the network element interface exceeds the maximum bit rate threshold; and if the initial rate of the enhanced uplink dedicated channel service exceeds the maximum bit rate threshold, configuring the current rate of the enhanced uplink dedicated channel service as the maximum bit rate threshold. The device comprises a rate threshold configuration unit and a service rate limit unit. The method and the device can effectively reduce bandwidth cost and save uplink transmission resources.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a rate control method and device for enhancing uplink channel services. Background technique [0002] The Wideband Code Division Multiple Access (WCDMA) system introduces the Enhanced uplink DCH (E-DCH) in the R6 version, and the maximum uplink bit rate of a single user can reach 5.76Mbps. However, the existing Iub interface transmission resources are designed based on carrying traditional Dedicated Channel (DCH for short), mainly carrying voice and low-rate packet domain services, and the bandwidth is relatively small. In commercial networks, there are often scenarios where the uplink transmission bandwidth of the entire cell is only 2M or even lower. At this time, if a high-speed E-DCH user is connected, then one user may exhaust the uplink transmission resources of the Iub port of the entire community, thereby causing other user calls in the entire community to be affected...

AI Technical Summary

Problems solved by technology

At this time, if a high-speed E-DCH user is connected, one user may exhaust the uplink transmission resources of the Iub port of the entire cell, which will affect the communication of other users in the entire cell and cause the deterioration of network performance.

Although the Iur port has more abundant transmission resources than the Iub port, it has similar problems to the Iub port because it bears the user load between two RNCs (Radio Network Controllers).
