Embodiment Construction

[0043] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0044] figure 1 A schematic flow chart of a VoLTE voice quality assessment method provided in this embodiment is shown, including:

[0045] S101. Collect voice and signaling data after optical splitting and aggregation at each interface.

[0046] Wherein, the interfaces include two media stream interfaces (Mb, Nb) and three control plane interfaces (S11, Gm, Mc). Specifically, RTP voice packets can be obtained by collecting two interfaces Mb and Nb; corresponding control plane data can be obtained by collecting three interfaces S11, Gm and Mc.

[0047] The above 5 interfaces are all data converged on the CE side through 2 / 8 splitting. After splitting, 80% of the o...

Abstract

Embodiments of the invention disclose a VoLTE voice quality assessment method and system. The method includes the following steps of: collecting voice and signaling data at each interface after lightsplitting and gathering; analyzing the voice and the signaling data, and performing an average subjective opinion MOS value evaluation on the analyzed media stream to obtain voice quality assessment data; adding user information and location information to the voice quality assessment data according to control plane data to generate a voice quality assessment file; and storing the voice quality assessment file to a database server. Through the addition of the user information and the location information in the voice quality assessment data to generate the voice quality assessment file, inquiry is convenient, the VoLTE voice quality assessment method is suitable for all VoLTE periods, and especially for scenes that VoLTE dials VoLTE users and the VoLTE dials traditional 2 / 3G users, and assessment results are reliable and accurate by performing a MOS value assessment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a VoLTE voice quality evaluation method and system. Background technique [0002] In the 2 / 3 / 4G converged network, voice quality distortion often occurs. VoLTE network elements and nodes are multiplied, and the structure is more complex. In the early stage of commercial use, voice distortion will occur when VoLTE users communicate with 2 / 3G users, which seriously affects actual user perception. An effective voice quality assessment method for VoLTE networks is urgently needed , can evaluate, monitor and query the voice service quality, and provide users with high-quality and satisfactory services. [0003] The monitoring method of the voice service of the LTE network in the existing method is aimed at the CSFB scenario, and evaluates and analyzes the voice quality of the 4G user during the conversation between the LTE network and the 2 / 3G netwo...
