[0002] During a telephone call, especially an international long-distance telephone call, after the call ends, the call may be continued because the calling party or the called party did not hang up the phone
But there may be such a situation, that is, the caller has ended the call, but the system does not think the call is over, and the system is still making the call, resulting in a lot of billing at the end and causing disputes. At the same time, for some emergency calls, the user may receive I have made a call but cannot speak due to conditions or other reasons. In these cases, how does the system identify it?
[0003] For the above problems, no solution has been given in the current technology

Abstract
The invention relates to a method for realizing long-time mute alarm. Wherein, the invention is characterized in that 1, exchanger sends the first message carried with mute alarm parameter to the gateway, to instruct the gateway to start long-time mute detection, while the mute alarm parameter comprises the preset time length; 2, responding the first message, gateway starts the long-time mute detection, when detecting that the mute time is over preset time length, sending second message to the exchanger, to instruct the exchanger to alarm; 3, responding the second message, the exchanger alarms. And the invention also provides a relative device. The invention can realize long-time mute alarm.
Description
technical field [0001] The present invention relates to the communication field, and more particularly, to a method and device for realizing long-time silent alarm. Background technique [0002] During a telephone call, especially an international long-distance telephone call, after the call ends, the call may be continued because the calling party or the called party did not hang up the phone. But there may be such a situation, that is, the caller has ended the call, but the system does not think the call is over, and the system is still making the call, resulting in a lot of billing at the end and causing disputes. At the same time, for some emergency calls, the user may receive I have made a call but cannot speak due to conditions or other reasons. In these cases, how does the system identify it? [0003] For the above problems, no solution has been given in the current technology. The H.248 protocol involved in this article is described below. The H.248 protocol, also...
