Method and system for transmitting IP message, negotiating bandwidth saving capability and saving network bandwidth

摘要

The present invention discloses a method for transmitting an IP message, negotiating a bandwidth saving capability and saving network bandwidth. The method for transmitting an IP message includes: A. sending, by a sender, more than one bandwidth saving capability supported by the sender to a receiver; B. selecting, by the receiver, one bandwidth saving capability from the more than one bandwidth saving capability sent by the sender according to the bandwidth saving capability supported by the receiver and sending the one bandwidth saving capability to the sender; C. obtaining, by the sender, a type of an IP message used for transmitting data according to the received bandwidth saving capability selected by the receiver; D. sending, by the sender, the IP message to the receiver after constructing the IP message for transmitting data by using the obtained type of the IP message. By applying the methods provided by the present invention, the bandwidth and resources of an IP bearer network in a communication system are saved.
