Method for improving link transmission capacity between base station and base station controller

Abstract

The invention discloses a method for increasing link capacity between a base station and a base station controller. The method comprises the following steps: reducing the number of background noise rate frames between the base station and the base station controller when two parties to a session on a link transmission line are in a silence state; stopping a transmission operation of reducing the background noise rate frames when the two parties to the session communicate, and recovering the transmission of the rate frames among normal links. One eighth rate frame on a forward link or a reverse link including full-shielded Abist link is reduced, which effectively relieves the transmission pressure of the Abist link, increases the transmission capacity of a system link, saves system resources, solves a bottleneck problem of the current system; meanwhile, the method saves Abist port bandwidth under the same load situation, which helps operators to save the transmission investment and maintenance cost and causes products to have stronger competitive power.

Description

technical field [0001] The present invention relates to the field of Abist link business services of a wireless communication system, and more specifically relates to an improvement of a method for increasing link transmission capacity between a base station and a base station controller. Background technique [0002] The Abist link is the link link between the base station and the base station controller. When the session is established, various rate frames are transmitted on the Abist link, including full rate, half rate, quarter rate and one eighth rate frames. etc., wherein the full-rate frame is a speech frame, and the one-eighth rate frame is a noise frame. At present, all rate frames on the Abist link in the existing system are generally sent as usual. [0003] However, after the session is established, except for full-rate frames, other rate frames occupy about half of the link overhead, which greatly reduces the system link transmission capacity, wastes system resou...

AI Technical Summary

Problems solved by technology

[0003] However, after the session is established, except for full-rate frames, other rate frames occupy about half of the link overhead, which greatly reduces the system link transmission capacity, wastes system resources, and becomes the bottleneck of the system. In some cases, the bandwidth of the Abist port is wasted, which is not conducive to saving the investment and maintenance costs of the operator in transmission, making the product not very competitive
