Problems solved by technology

Repeated VQE for terminals will bring two problems: one is the waste of resources and affects the capacity of the network; the other is that multiple VQE processing will lead to the decline of voice quality, which is counterproductive
[0004] At present, the static VQE configuration method commonly used in the MGW of the core network cannot meet the needs of practical applications, thus greatly affecting the wide application of VQE in the core network

Embodiment Construction

[0025] The core idea of ​​the present invention is: the VQE function of the existing core network MGW is basically statically configured, once configured, it cannot be changed casually, so the voice service it provides is also immutable. However, in the actual call process, due to the call environment and network resource occupation, various voice quality degradations may occur. The present invention defines a unified VQE capability support table in the network. When the call is established, the devices at all levels in the call link report the VQE capability support table level by level, and the MGW or MSC server, etc., according to the VQE capability support table reported by the core network equipment, Then formulate a corresponding VQE strategy based on its own VQE capability, and close a certain VQE capability of the relevant MGW or enable a certain VQE capability that has been turned off according to the VQE strategy, so as to avoid repeatedly setting a certain VQE capabi...

Abstract

The invention discloses a speech enhancement method and relates to speech enhancement technology. The method is to solve the problem that the speech enhancement ability can not be dynamically adjusted with the present 3G core network. The technical scheme is: A. when a call link is established, equipment of every stage reports an own VQE capability supporting form to the upper stage equipment thereof; B. the core network equipment of the call link generates the VQE strategy of the call link according to the VQE capability supporting form; C. according to VQE strategy, adjusting the VQE ability that the core network equipment supports. The invention assures the necessary VQE capability and avoids resource waste and repeat processing at the same time.

Description

technical field [0001] The present invention relates to a Voice Quality Enhancement (VQE, Voice Quality Enhancement) technology, in particular to a configuration method of a voice enhancement function. Background technique [0002] VQE was first applied to a voice user terminal UE to enhance the voice quality of the UE. However, due to the large number of UE manufacturers and various types of terminal equipment, the differences between user terminals are relatively large. Due to differences in production time, market positioning, and technical level, different terminals have different internal support for VQE functions. . It may happen that the terminal does not support the VQE function, supports some VQE functions, or supports all VQE functions. In order to achieve a better call effect, it is necessary for a media gateway (MGW, Media Gateway) of the core network to provide a voice enhancement function that is not available in the user terminal. In particular, if the circ...
