Detection technology and voice call backup linkage method and device thereof

Abstract

The invention discloses a detection technology and voice call backup linkage method, which is applied to a system which comprises a voice sender and a voice receiver, the detection technology and voice call backup linkage method comprises the following steps: a call state message of the voice call receiver is monitored by the voice call sender; the voice call sender judges whether a main call routing can be used to initiate a call to the voice call receiver or not according to the monitored call state message, if the main call routing is unavailable, when a call is initiated, the voice call sender switches to a backup routing to initiate the call to the voice call receiver. The network state or the processing capacity can be obtained speedily by the invention, the detection technology and the call routing are linked, and the correct call routing is selected fast by equipment, thereby increasing the efficiency.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a detection technology and voice call backup linkage method and device. Background technique [0002] When the call originator initiates a connection to the voice receiver, but for some reason the receiver cannot get a response message, then the call originator can switch to the next reachable route in time, such as PSTN (Public Switched Telephone Network, public switched telephone network) chain Voice over Internet Protocol (VoIP) link to establish a new connection to the voice receiver, this function is called call backup. [0003] Call backup networking in the prior art such as figure 1 Shown: Router A and Router B are connected through IP network and PSTN network respectively. Telephone A connected to Router A can call Telephone B connected to Router B through IP network or PSTN network. Normally, Telephone A calls Telephone B through the IP network. When the IP netw...

AI Technical Summary

Problems solved by technology

Although the waiting timeout time is adjustable (for example, 3 seconds to 30 seconds), if the setting is too short, the other party’s network will be slightly unstable and delayed, and it will be directly switched to the backup route; if the setting is too long, the switching speed will be slow , the connection time increases, even if the call can be established, it is actually unavailable to the user

[0006] Second, the switching efficiency in call backup is low and not timely

Since each time a call is initiated, the initiator must try to establish a connection with the receiver, and switch to the backup route after there is no response. In the case of multiple call routes, it needs to be tried one by one, resulting in longer call establishment time, and ultimately resulting in inefficiency of switching to the backup route when the primary route fails

[0007] 3. When the IP network of the receiver is reachable, but the voice service module of the receiver cannot be used, the sender still cannot be switched in time
