Problems solved by technology

[0006] (1) It is impossible to test the voice transmission capacity of the access network when a specific voice technology is used. Due to the limitation of bandwidth, voice coding should take into account both capacity and quality, and only evaluate the quality of voice coding without considering the quality of voice coding capacity is meaningless
[0007] (2) The selection of the channel may not be representative. For the access method of resource competition, the network environment of different channels is different. Only the transmission situation of one channel is recorded, and only the simulation evaluation of this channel may not be able to represent the whole. voice transmission quality
[0008] (3) When the speech quality of multiple speech codes is equivalent under the test capacity, it is impossible to further evaluate the capacities of various speech codes

Embodiment Construction

[0032] The method for testing the VoIP voice technology capacity under the access network proposed by the present invention is used to test the maximum number of terminals that can access and run the VoIP voice technology under a kind of access network. The access network includes but is not limited to the WLAN access network, The following mainly uses the WLAN access network as an example for description.

[0033]Under the same access network conditions, different voice technologies may be used, and the capacity of the network may be different. The present invention uses a capacity pre-test and conducts a voice quality test on multiple capacity test points, and obtains that the access network is using a certain voice technology. The capacity and quality function curves of a specific speech technology, and further get the capacity of the speech technology. During the test, the terminals participating in the test are divided into background terminals and target terminals. The b...

Abstract

This invention relates to a test method for VoIP voice technological volume under an access network including the following steps: preparing voice materials, setting up a test environment by setting at least two accesss points and multiple accesss terminals in the tested access network, carrying out pre-testing the volume of the voice technology to determine the reference volume in the access network then to determine multiple volume test points and carry out voice quality test at the points and record related test data to be analyzed and processed to determine the volume and quality results under said access network.

Description

technical field [0001] The invention relates to a method for testing the capacity of the VoIP voice technology, in particular to a method for testing the capacity of the VoIP voice technology under an access network. Background technique [0002] With the development of wireless communication technology and voice communication technology, a Voice over Wireless Local Area Network (VoWLAN) technology that uses a wireless local area network (Wireless Local Area Network, WLAN for short) to provide voice services emerges as the times require. VoWLAN technology uses the existing WLAN network to realize wireless IP (Voice over Internet Protocol, VoIP for short) calls, and users can make voice calls at any time within the coverage of the WLAN network through VoWLAN terminal equipment. This not only takes advantage of the low cost of the IP network, but also enables users to obtain the convenience brought by WLAN wireless access. [0003] Voice technology, usually including voice co...
