Embodiment Construction

[0010] The present invention will be described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 shown. During the conversation, the busy tone detection module waits for the busy tone; when the busy tone detection module of the loop interface detects the busy tone during the conversation, it immediately disconnects the CODEC output time slot. This prevents the busy tone from being transmitted to the conference. Even part of the busy tone input into the conference before the CODEC output time slot is disconnected will be filtered out by the busy tone detection module, so other loop conference members will not be affected by the busy tone. When the second busy tone is detected, the following busy tone may not be detected due to overtime; because the busy tone detection part is before the CODEC and the switching network. Therefore, the busy tone detection of the loop interface that disconnects the CODEC output will not be affected in any way. Afte...

Abstract

The invention discloses a method for detecting and processing busy tone in a meeting consisting of loops, which relates to a busy tone detection problem in the meeting consisting of a plurality of loop members in a communication system in the technical field of telephone network communication. The method comprises the following steps: when a busy tone detection module of a loop interface detects the busy tone during the conversation process, a CODEC (encoder and decoder) is immediately disconnected for outputting a time slot, thereby preventing the busy tone from being transferred into the meeting; and the busy tone detection module detects the busy tone of three cycles, the automatic hanging up is carried out, and the CODEC is re-connected for outputting, thereby achieving the function of not affecting the next loop interface. The method is simple and reliable. The function of having the meeting through the loop interface can be realized under the situation of not changing hardware configuration.

Description

technical field [0001] The invention belongs to the technical field of telephone network communication, and particularly relates to a busy tone detection processing method in a conference composed of a plurality of loop members involved in the busy tone detection problem in a conference composed of multiple loop members in a communication system. Background technique [0002] In a conference system composed of ring members, if a conference member hangs up, the ring interface occupied by the user will inevitably receive the busy tone sent by the switch to which the user who hung up previously belongs. It takes a certain amount of time for the loop interface to hang up after detecting the busy tone. So during this time, the busy signal will be sent to the conference. The busy tone in the conference will be transmitted to other loop interfaces at the same time. It causes other loop interfaces to detect busy tone, which may cause all loop members to hang up. cause the meeting...
