Problems solved by technology

When multiple Abis are connected to the IP network, because the same IP interface load threshold is used, some stations reach the threshold while other stations have very little load, so the entire IP network resources cannot be dynamically shared among base stations, and network resources cannot be fully utilized.

Abstract

The invention discloses a method and device for adjusting an IP interface AMR speech coding rate. The method of the invention includes: an IP network quality measurement unit measures the IP network transmission quality to obtain an IP network transmission quality parameter Qip; the air interface quality measurement unit measures the air interface The uplink and downlink transmission quality obtains the air interface quality parameter Qum; the AMR speech coding rate adjustment unit adjusts the AMR speech coding rate according to the air interface quality parameter Qum and the IP network transmission quality parameter Qip. Since the present invention adjusts the AMR coding rate according to the IP network transmission quality, thereby overcoming the independent shortcomings of IP link transmission control and AMR voice rate adjustment in the prior art, and solving the problem that the IP link voice transmission quality cannot be controlled in the prior art The problem.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for adjusting an IP interface AMR speech coding rate. Background technique [0002] In the evolution of the network-side interface of the GSM system, the IP (Internet protocol Internet Protocol)-based Abis interface is gradually adopted. When the GSM system adopts IP interface, especially the IP-based Abis interface, because the IP interface is sensitive to bandwidth, jitter, and packet loss, the quality of voice transmission will be affected to a certain extent, resulting in poor voice quality. [0003] The method described in this paper, combined with IP transmission quality measurement and AMR (Adaptive Multi-Rate adaptive multi-rate) speech coding technology, adjusts the AMR speech coding rate according to the IP transmission quality, optimizes the transmission rate of the IP interface to improve the overall speech quality of the GSM system . [0004] At pres...
