Method for negotiating about the media stream packet time length

Abstract

A method for negotiating about the media stream packet time length includes: the negotiation initiating party transmits the media stream codec formats supported by itself and the supported packet time length capability information according to each codec format to the negotiation responding party; the negotiation responding party determines the media stream codec formats and the packet time lengths used by the codec formats which are supported by both parties based on the received media stream codec formats and the supported packet time length capability information according to each codec format; the negotiation responding party notifies the determined codec format and the packet time length capability supported by the codec format to the negotiation initiating party in order to finish the negotiation. The invention enables both of the communicating parties to exactly negotiate the packet time length capability supported by each codec capability, thereby it ensures both parties can use the optimum matching packet time length and the communication quality is improved.
