Abstract
Method for testing the transmission quality of a bidirectional real speech transmission or multicast connection over an IP network between a first VoIP endpoint and a second VoIP endpoint. A first number of the RTP speech packets transmitted from the first to the second VoIP endpoint, and a second number of the RTP speech packets transmitted from the second to the first VoIP endpoint being detected over a predetermined, sufficiently long time period, and the first and second numbers being subjected to arithmetic processing, as a result of which a value representing the transmission quality is obtained.
Claims21
A method for testing the transmission quality of a bidirectional real speech transmission or multicast connection over an IP network between a first VoIP endpoint and a second VoIP endpoint, comprising:
- transmitting a first number of RTP speech packets in a direction of the second VoIP endpoint, and transmitting a second number of the RTP speech packets in a direction of the first VoIP endpoint;
- and
- detecting at a detection point on a transmission channel between the first and the second VoIP endpoint over a predetermined time period, and arithmetically processing the first and second numbers, and outputting a value representing the transmission quality.
A method for controlling a speech transmission over an IP network between a first VoIP endpoint and a second VoIP endpoint, comprises:
- transmitting a first number of RTP speech packets in the direction of the second VoIP endpoint, and transmitting a second number of the RTP speech packets in the direction of the first VoIP endpoint;
- and
- detecting at a detection point on a transmission channel between the first and the second VoIP endpoint over a predetermined time period, and arithmetically processing the first and second numbers, and outputting a value representing the transmission quality;
- and routing the connection between the first and second VoIP endpoints in the valve.
A method for controlling a speech transmission over an IP network between a first VoIP endpoint and a second VoIP endpoint, comprises:
- transmitting a first number of RTP speech packets in the direction of the second VoIP endpoint,
- transmitting a second number of the RTP speech packets in the direction of the first VoIP endpoint;
- detecting at a detection point on a transmission channel between the first and the second VoIP endpoint over a predetermined time period, and arithmetically processing the first and second numbers, and outputting a value representing the transmission quality;
- and
- setting transmission parameters based on the valve.
A system comprising:
- a detecting unit, arranged at a detection point on a transmission channel between a first and a second VoIP endpoints to detect a first number of RTP speech packets transmitted in a direction of the second VoIP endpoint, and to detect a second number of the RTP speech packets transmitted in a direction of the first VoIP endpoint;
- and
- an arithmetic processing unit connected on the input side to the detecting unit to calculate a value representing the transmission quality from the first and second numbers.
