Embodiment Construction
[0041] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0042] In the existing howling recognition methods, there are problems of slow response and false detection of howling recognition, and the two problems are contradictory. How to neutralize the contradiction between the two and improve the accuracy and speed of howling recognition at the same time? The speed of howling recognition is fast, which is also conducive to the response speed of howl...

The invention provides a squeal scene recognition method based on calling indication, and user equipment. The method comprises the steps that monitoring UE enables a preset first squeal parameter threshold to be adjusted into a second squeal parameter threshold after receiving a calling indication sent by a base station, wherein the first squeal parameter threshold is greater than the second squeal parameter threshold; the monitoring UE recognizes whether squeal is generated or not in a preset time after the calling indication is received according to the second squeal parameter threshold; the monitoring UE enables the second squeal parameter threshold to be adjusted into the first squeal parameter threshold after the preset time arrives; the monitoring UE recognizes whether squeal is generated or not according to the first squeal parameter threshold when the monitoring UE monitors that there is no squeal according to the second squeal parameter threshold. The method and UE can improve the squeal recognition accuracy and speed at the same time.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a howling scene recognition method and user equipment based on a lecture indication. Background technique [0002] In the existing mobile communication system, the trunking communication system has become an important branch of the mobile communication system. In the trunking service of the trunking communication system, there may be one or more groups in one cell, and multiple user equipments (User Equipment, hereinafter referred to as UE) in one group, and UEs in the group can be classified according to their characteristics. It is the speaking UE and the listening UE. [0003] In a group, there is only one presenting UE at the same time. Since most of the group UEs in the trunking communication system work outdoors or in factory buildings with high background noise, the volume is required to be loud, so the uplink and downlink volume gains of the group UEs are...
