Problems solved by technology

However, according to the existing AG processing flow and the method of improving reliability, the problem of lack of VoIP resources within the AG cannot be solved
Then, when an AG itself lacks free VoIP resources, it cannot allocate VoIP resources to the connected users, resulting in users being unable to make or receive VoIP calls normally.

Embodiment Construction

[0045]The core idea of ​​the present invention is: according to the current command issued by the SS device to the AG, after the AG detects its own corresponding VoIP resource information, it initiates a request to other AGs as needed, and performs corresponding processing according to the response messages returned by other AGs . Moreover, according to the current command may be a command to allocate VoIP resources or a command to release VoIP resources, the present invention has two implementation schemes. The present invention realizes that different AGs can share VoIP resources, so that AGs lacking VoIP resources can share VoIP resources with other AGs that have idle VoIP resources. Then, when a certain AG lacks VoIP resources, or even all VoIP resources fail, it can share the idle VoIP resources of other AGs. This ensures that the users connected to the AG lacking VoIP resources can still make or receive VoIP calls normally.

Abstract

The invention discloses a method of access gateway to share network telephone resources, which comprises the following steps: the access gateway is connected with other access gateways. According to the current order delivered to the access gateway by the soft switching device, the access gateway determines whether to initiate requests to other access gateways or not after testing the corresponding network telephone resource information. If no, the access gateway then directly implements the orders delivered by the soft switching device; if yes, the access gateway should initiate requests to other access gateways and coordinate with other access gateways to complete the orders delivered by the soft switching device. The invention ensures that the access gateway with deficient network telephone resources can apply for and utilize the network telephone resources of other access gateways for users with access to the access gateway, thus enabling the users to make or answer network telephone calls normally.

Description

technical field [0001] The invention relates to a technology for sharing VoIP (Voice over IP) resources, in particular to a method for an access gateway to share VoIP resources. Background technique [0002] Next Generation Network (NGN, Next Generation Network) represented by Soft Switch (SS, SoftSwitch) is gradually being planned as the main network construction mode in the construction of domestic and foreign telecommunication networks. In the history of voice communication development, NGN technology is another technological revolution following the revolution from analog technology to digital program-controlled technology. To put it simply, NGN technology is a technology that transmits voice communication on a data network in the form of packet data packets. NGN technology combined with the development of data communication has promoted the development of the entire communication network. [0003] The access gateway (AG, Access Gateway) is located at the edge layer of...
