Embodiment 1

[0050] figure 2 It is a schematic flowchart of a method for detecting service quality of an IP access network according to preferred embodiment 1 of the present invention. Such as figure 2 As shown, it is the case that the network side actively initiates a call mode. This embodiment uses SIP signaling as an example to illustrate the process of IP access network call quality evaluation. The method includes the following steps:

[0051] In step S202, the automatic call strategy is activated on the network side, and an automatic call process for testing terminal X in a certain IP access area is prepared to be started.

[0052] Step S204, the network side initiates a session establishment request to the test terminal X in the IP access area.

[0053] Step S206, after receiving the session establishment request message, the automatic response test terminal deployed on the IP access network side automatically sends a session connection indication signaling (for example, SIP 180...

Embodiment 2

[0065] image 3 It is a schematic flowchart of a method for detecting service quality of an IP access network according to the second preferred embodiment of the present invention. Such as image 3 As shown, it is the case that the terminal side actively initiates the call mode, and this embodiment uses SIP signaling as an example to illustrate the process of evaluating the call quality of the IP access network. The method includes the following steps:

[0066] In step S302, the voice terminal user initiates a call to the network side.

[0067] Step S304, the network side automatically sends a session connection indication signaling (for example, SIP 180 Ring) to the voice terminal.

[0068] In step S306, the network side automatically sends a session response indication signaling (for example, SIP 200 OK) to the voice terminal, and at this time the session has been successfully established between the network side and the voice terminal.

[0069] Step S308, the network si...

Abstract

The invention discloses a method and device for detecting the service quality of an IP (Internet Protocol) access network. The method comprises the steps as follows: network side call information of a call and media signals are collected on a network side; and the call quality parameter MOS (mean opinion score) of a tested call is acquired on the network side according to the call information and the media signals. Through application of the invention, the problem that in correlation techniques, the service quality of an IP access network can not be measured accurately due to distemperedness in evaluation of the service quality of the IP access network can be solved, further the service quality of the IP access network can be evaluated accurately, so that the system performance can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for detecting service quality of an IP access network. Background technique [0002] In the modern telecom network architecture, the core network system has transitioned to the NGN next-generation network based on all IP bearer methods such as softswitch and IMS, and supports multiple IP access methods for fixed / mobile terminals (such as LAN, WLAN, xDSL, etc.) , xPON, FTTx, GPRS, CDMA2000, UMTS, etc.), and can provide unified voice, video, data and multimedia services for these access terminals. [0003] The bearer of the NGN network is based on the IP packet transmission technology, and the core network side cannot perceive the service quality of the end user's IP access side network. However, in a commercial telecom network, the IP access network on the end user side has many layers and a complex structure. If an end user complains about poor voice service...
