Problems solved by technology

[0003] In the above solution, the prior art uses a manual method to configure the corresponding relationship between the called number and the destination on the gateway interaction center node. This method is relatively cumbersome to configure the gateway interaction, especially in a large VOFR network. The configuration workload on the gateway interaction center node is quite large, and when the acceptable phone number of the edge node changes, the configuration on the gateway interaction center node must be updated synchronously, otherwise the call will fail

Embodiment Construction

[0028] The method for automatically registering node numbers in the frame relay voice gateway switching network proposed by the present invention is described in detail in conjunction with the embodiments as follows:

[0029] The implementation method of this embodiment is: the gateway interaction center node regularly sends a full phone number information request message or a heartbeat information request message to the edge node, and these two messages do not carry any other information. When the edge node receives the full phone number information request message, it immediately returns the full phone number information message to the gateway interaction center node, and the message contains all locally acceptable phone number information configured at the local end. The gateway interaction center node extracts all the phone numbers according to this message, and generates a corresponding relationship table between the called number and the interface and DLCI number accordin...

Abstract

Interactive central node of gateway sends out request message of full phone number information or request message of heartbeat information to each fringe node timely. When receiving request message of full phone number information or request message of heartbeat information, each fringe node sends back request message of full phone number information or request message of heartbeat information to the interactive central node of gateway instantly. The interactive central node of gateway picks all phone numbers from message received, and based on interfaces received, DLCI generates coincidence relation table among called number, interface and DLCI. Moreover, based on practical situation, content of the said table is modified. The invention reduces workload of configuration for interactive gateway effectively, and guarantees consistent configuration between interactive central node of gateway and fringe nodes.

Description

technical field [0001] The invention belongs to the technical field of computer networks, in particular to a method for automatically registering node numbers in a frame relay voice gateway switching network. Background technique [0002] The frame relay network is a point-to-point network. In a large-scale frame relay voice (VOFR) network, all telephone numbers and the ways to reach these telephone numbers must be configured for each VOFR device, which increases the VOFR network cost of configuration, maintenance, and management, in order to reduce the cost of configuration, maintenance, and management, the applicant proposed a frame relay network structure scheme of gateway interaction (GATE SWITCH), the core of which is to use one or several One VOFR device acts as a gateway interaction center node, while other VOFR devices act as edge nodes. All calls from edge nodes are called to the gateway interaction center node first, and then the gateway interaction center node sel...
