Problems solved by technology

[0003] The transmission interval of voice data packets is relatively short, generally 20ms. If a small amount of noise packets are occasionally received, the human ear cannot distinguish them, but when the noise packets accumulate to a certain amount in a short period of time, they will be perceived by the human ear. Affects the user's perception and normal communication

Embodiment 1

[0034] In this embodiment, voice service noise detection is performed on voice frames sent from the core network CN to the RNC, and the received voice frames are downlink Iu-UP (Iu User Plane, Iu interface user plane) voice frames.

[0035] like figure 2 As shown, the 3GPP specification 3GTS 25.415 Iu-UP protocol defines the Iu-UP Type0 frame structure used to transmit voice service data. The specific content of each field can be found in the protocol specification, and will not be described in detail here. Then the detection field in the agreed voice frame format includes:

[0036] 1) The sender indicates whether the voice frame is a normal frame FQC (Frame Quality Classification, frame quality classification) field

[0037] For the RNC, the frame quality classification FQC of voice frames sent by the core network CN has three levels, 0 is a normal frame (frame good), 1 is a bad frame (frame bad), and 2 is a bad frame caused by wireless reasons (frame bad). due to radio), ...

Embodiment 2

[0045] In this embodiment, voice service noise detection is performed on the voice frames sent from the user terminal UE to the RNC, and the received voice frames are uplink FP (Frame Protocol, Frame Protocol) voice frames.

[0046] like image 3 As shown, the definition of the FP frame refers to the 3GPP specification 3GTS25.427 protocol, and the specific content of each field can refer to the protocol specification, which will not be described in detail here. Then the detection field in the agreed voice frame format includes:

[0047] 1) The sender indicates whether the CRC of the voice frame is correct or not in the CRCI (CRC indication) field

[0048] Before sending the FP voice frame, the sending end performs CRC check on each transmission block, and indicates the check result to the receiving end through CRCI. For RNC, when any CRCI in the voice frame indicates an error, it considers The voice frame is a noise packet.

[0049] 2) Payload CRC field

[0050] If the RNC...

Abstract

The invention discloses a method and a device for detecting a voice service noise. The method comprises the steps as follows: receiving a voice frame transmitted by a transmitter; detecting whether the voice is correct or not according to any one detection field of a promissory voice frame format, wherein the detection field is relative to the correctness of the voice frame; and determining a noise package is received when the voice frame is incorrect. The method and the device can detect that whether a noise is generated during the calling of users, can assist positioning or solve a partial noise problem, or reduce the positioning range of the noise problem, and directly or indirectly improve voice calling quality of users.

Description

technical field [0001] The present invention relates to the technical field of voice communication, in particular to a voice service noise detection method and device Background technique [0002] At present, in the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system, the access network has relatively few detection methods for service quality, and relatively few voice service noise detection methods. [0003] The transmission interval of voice data packets is relatively short, generally 20ms. If a small amount of noise packets are occasionally received, the human ear cannot distinguish them, but when the noise packets accumulate to a certain amount in a short period of time, they will be perceived by the human ear. Affect the call user's perception and normal communication. [0004] Therefore, there is currently a lack of an effective voice service noise detection method to further locate or solve some noise problems, or narrow the scope of noise probl...
