Description

technical field

[0001] The invention relates to an IP telephone system, in particular to a cross-gatekeeper call processing method. Background technique

[0002] The IP telephone system is a new type of telecommunication service developed in recent years based on packet network transmission of voice signals. Among them, the IP telephone system supporting the H.323 protocol is the mainstream of the new generation of broadband IP network communication. The H.323 system mainly includes four entities: terminals, gateways, gatekeepers, and multi-point control units. In the H.323 system, one or more gatekeepers can exist in different regions and can communicate with each other. All H.323 All node devices must register with the gatekeeper in their region to obtain the application of the H.323 protocol. The gatekeeper is a device specified in the H.323 protocol to manage the h323 domain. It provides address resolution and access control functions for terminals, gateways and MCUs in...

Examples

Embodiment Construction

[0037] The basic idea of ​​the cross-gatekeeper call processing method of the present invention is: in the call process, the relevant information obtained by the calling gatekeeper and the called gatekeeper is stored in a gatekeeper place, so that the gatekeeper can obtain a complete Calling and called node information, call information, and billing information. When the calling gatekeeper GKa sends a location request LQR to the called gatekeeper GKb, the call information and calling node information obtained by the calling gatekeeper GKa are sent to the called gatekeeper GKb through the location request signaling LRQ, and stored in Called gatekeeper GKb.

[0038] In order to better understand the present invention, the present invention will be described in detail below in the form of examples.

[0039] image 3 An embodiment of the flow of inter-gatekeeper calling in the present invention is shown. Among them, at the calling end, the call signaling adopts the direct route s...
