Abstract

The invention discloses a method, device and system for acquiring a multi-address message, which belongs to the communication field and solves the problem that the communicating quality between a media gateway and a media gateway controller is influenced because the media gateway can only acquire one IP address corresponding to the media gateway controller through domain name resolution (DNS) and SCTP (Stream Control Transmission Protocol) coupling can not be established between the media gateway and the media gateway controller. The technical scheme of the invention comprises the steps of: receiving DNS request messages sent by the media gateway, obtaining more than two address messages corresponding to the media gateway controller according to the domain name of the media gateway controller, carried in the DNS request messages, and generating DNS response messages according to the more than two address messages, and sending the DNS response messages to the media gateway. The method, the device and the system for acquiring the multi-address message, which are provided by the invention, can be applied to communication between the media gateway and the media gateway controller.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for acquiring multi-address information. Background technique [0002] Currently, the Media Gateway (MG) can establish a Stream Control Transmission Protocol (SCTP) coupling with the Media Gateway Controller (MediaGateway Control, MGC), and communicate with the Media Gateway Controller through multiple communication links. . Specifically, the media gateway obtains multiple IP addresses corresponding to the media gateway controller, and sends the multiple IP addresses to the media gateway controller in an initialization message, and the media gateway controller A stream control transmission protocol SCTP coupling is established between the address and the media gateway, and in the subsequent communication process, the multiple communication links established by the stream control transmission protocol SCTP coupling are used to communicate with the med...
