Method for implementing media gateway function, radio access control device and radio access system

摘要

A method for implementing the media gateway function is disclosed by the embodiment of the present invention, including: receiving a first signaling message; determining to perform a processing of a base station application layer or a processing of a media gateway control application layer according to a Simple Control Transmission Protocol (SCTP) link, wherein the SCTP link is indicated by the first signaling message; if determine to perform the processing of the media gateway control application layer, routing traffic data to a destination device. A radio access control device and a radio access system according to the above mentioned method are further disclosed. According to the embodiment of the present invention, the exchange number of an IP packet is reduced, and the bearer is separated from the control.
