Embodiment Construction

[0050] Such as figure 1 Shown, the VOIP (Voice over Internet Protocol Internet telephone) gateway voice link backup method of an embodiment of the present invention, comprises the steps:

[0051] Step S101, switching judging step: judging whether link switching is required;

[0052] Perform a link switch if necessary,

[0053] Link switching includes the following:

[0054] Step S103, call judging step: judging whether there is an online call,

[0055] If it is judged, execute

[0056] Step S105, uplink port switching step: save the call scene, record the relevant uri (Universal Resource Identifier) ​​information, and the calling or called role in the call,

[0057] Modify the routing policy, switch to the backup uplink outlet as the uplink port, use the switched uplink port to register uri, and establish a new media data channel;

[0058] Step S107, call role judging step: judging whether there is a caller in the saved call role at the call scene,

[0059] if yes, proce...

Abstract

The invention provides a VOIP (Voice over Internet Protocol) gateway voice link backup method and system. The VOIP gateway voice link backup method comprises the following step: if necessary, performing link switch. The link switch comprises the following steps: judging whether on-line communication exists or not; if the on-line communication exists, saving the scene of the on-line communication, recording the related uri and roles in the on-line communication, switching to the port of a backup uplink, taking the port of the backup uplink as an uplink port, and building a new media data channel; judging whether a calling party exists in the saved scene; if the calling party exists, obtaining the recoded uri information to start an SIP (Session Initiation Protocol) link call, and interacting with an SIP server; if a called party exists in the saved scene, waiting for receiving calling request information, and interacting with the SIP server; associating the built new media data channel with an original communication terminal. According to the VOIP gateway voice link backup method and system, a data link is recovered by switching the original uplink port; the new SIP link and the media data channel are built by recovering voices; the media data channel is associated with the data channel of the original conversation terminal. Therefore, the original communication terminal can be used for receiving and sending media data through the new media data channel, and the purpose of backing up the VIOP gateway uplink and the link switch function are achieved.

Description

technical field [0001] The invention relates to a link switching and recovery method, in particular to a VOIP gateway voice link backup method and a VOIP gateway voice link backup system. Background technique [0002] Most of the link switching and recovery methods adopted by some products now are to play a busy tone to the user when the link is interrupted, notify the user to go offline and hang up the phone, and then switch the uplink to the backup uplink internally. The call can be made again. Such a method of link restoration and handover requires user participation, which makes the user feel dissatisfied with the link handover; interrupts the user's original conversation, even after the link is restored, the user's conversation may be unsustainable. Contents of the invention [0003] Based on this, it is necessary to provide a VOIP gateway voice link backup method for link switching without user participation. [0004] At the same time, it provides a VOIP gateway vo...
