Method for controlling real time service on router

Abstract

The present invention provides real time service controlling method in router. It contains 1, soft switching system transmitting RTCP message, said RTCP message describing current real time service RTP message band width requirement; 2, router according to received above-mentioned RTCP message judging whether existing corresponded telephone channel, when existing or not existing corresponded telephone channel, said RTCP message corresponded port satisfying said RTCP message band width requirement, retransmitting said RTCP message; 3, repeating step 2 operation until said message retransmitted to opposite terminal soft switching system. Said method can control new real time service establishment and through controlling new conversational establishment to protect established conversational service, thereby ensuring service real time and reliability.

Description

technical field [0001] The invention relates to a method for controlling real-time services, in particular to a method for controlling real-time services on a router. Background technique [0002] Real-time business means that the sending and receiving of business must be completed in a very short time. The most common audio conversation between two people, the early technology is based on circuit switching, the current development trend is the transition to packet switching. [0003] As a mature communication technology, VoIP (Voice over IP) has been widely used in NGN (NextGeneration Network). The IP network guarantees voice quality as much as possible by using a differentiated services model (Differentiated Services Model, Diffserv), but the ability to support voice services is not satisfactory. [0004] There are many schemes for processing real-time services in the prior art, and the following two commonly used schemes are taken as examples for illustration. [0005]...

Problems solved by technology

[0007] The disadvantage of the first solution is: since there is no restrictive relationship between RTP and RTCP, the RTCP message only counts the RTP message to determine the quality of the link, and there is no way to carry out effective preventive treatment

[0010] The disadvantage of the second solution is that when faced with high traffic volume, that is, when the voice traffic exceeds the guaranteed bandwidth of the router, packets will be discarded and the delay will increase.

[0011] At this moment, the softswitch system will have a large number of session packet loss alarms, delay alarms, and jitter alarms. Only packet loss can be seen on the router, and online sessions cannot be protected.
