Problems solved by technology

In a voice call, once one of the calling party and the passing router does not support ECN, the existing ECN solution is unavailable
However, the actual network structure is very complex, and it is difficult to ensure that all entities passing through the route between the sending UE and the receiving UE support ECN, which greatly limits the scope of use of the ECN solution.
In addition, the prior art cannot select an appropriate speech coding method according to the network load condition during the call establishment phase

Abstract

The embodiment of the invention discloses a speed adjusting method, system and coding scheme selection method and a device thereof. The speed adjusting method includes: a downlink data packet sent by transmitting equipment is received, wherein the explicit congestion notification ECN mark the down link data packet is an explicit congestion notification capacity transmission ECT mark or a non-ECT mark; when congestion happens, the ECN mark of the downlink data packet is set to be a congestion mark, and the downlink data packet carrying the congestion mark is sent to receiving equipment, so as to be convenient for the receiving equipment to control downlink speed according to the congestion mark. The embodiment of the invention realizes that ECN can be utilized to control congestion even if transmitting equipment or a router on the route between transmitting equipment and receiving equipment does not support ECN, so that ECN scheme is stronger; and coding scheme can be selected according to network load condition, thus improving network capacity.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a rate adjustment method, system, and encoding mode selection method and device. Background technique [0002] Voice over Internet Protocol (Voice over Internet Protocol; hereinafter referred to as: VoIP) generally uses Adaptive Multi-Rate Speech Coding (Adaptive Multi-Rate; hereinafter referred to as: AMR), including: Narrowband Adaptive Multi-Rate Speech Coding (AMR-Narrow Band ; Hereinafter referred to as: AMR-NB) and wideband adaptive multi-rate speech coding (AMR-Wide Band; hereinafter referred to as: AMR-WB) and other variable-rate speech coding formats encode speech, and AMR is then carried on the real-time transport protocol ( Real-time Transport Protocol; hereinafter referred to as: RTP) / User Datagram Protocol (UserDatagram Protocol; hereinafter referred to as: UDP) / Internet Protocol (Internet Protocol; hereinafter referred to ...
