Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] According to an embodiment of the present invention, a calling method is provided. This method can be based on Figure 1a and Figure 1b shown in the media gateway.

[0029] Figure 1a It is the schematic diagram 1 of the media gateway according to the embodiment of the present invention, which shows that in the media gateway without resource-saving processing, the calling user sends the voice signal to the media gateway, performs TDM exchange, and packs it into UDP after silence compression and other processing The data packet is finally forwarded through media NAT. If the called party is a user in another media gateway, the media packet is transmitted to another media gateway throug...

Abstract

The invention discloses a calling method and a media gateway. The method comprises the following steps of: receiving a calling from a calling party by the media gateway; judging whether a called party is a user of the media gateway according to the calling; if so, deleting an RTP (Real Time Protocol) resource of the called user and a RTP resource of the calling user, and carrying out the calling of the calling user and the called user. The invention saves the RTP resource.

Description

technical field [0001] The present invention relates to the communication field, in particular to a calling method and a media gateway. Background technique [0002] In the NGN network, the role of the Media Gateway (MG for short) is to pass the voice signal transmitted by the user through the time division multiplexing (Time Division Multiplex, TDM for short) switching network, and then pass through technologies such as silent compression and digital / analog conversion. , and finally form a Real Time Transfer Protocol (Real Time Transfer Protocol, RTP for short) packet or a User Data Protocol (User Date Protocol, UDP for short) packet, and then forward it to a designated network via NAT. Therefore, in the above process, the voice media packets between the calling party and the called party will be forwarded through the NAT. [0003] In the above process, if the called user is inside another media gateway, NAT forwarding will forward the voice media packet of the calling use...
