Abstract: Embodiments of the present invention provide a method, a device, and a system for discovering a wireless access point AP, so as to achieve a purpose of rapidly discovering an available wireless access point and saving electricity of a mobile terminal STA. A base station controller BSC receives a request message sent by a mobile terminal STA, acquires information about one or more APs near the STA from an access controller AC, and sends a notification message to the STA, so that the STA performs an active scan based on a service set identifier SSID to discover a corresponding AP.

Abstract translation: 本发明的实施例提供了一种用于发现无线接入点AP的方法，设备和系统，以便实现快速发现可用无线接入点并节省移动终端STA的电力的目的。 基站控制器BSC接收移动终端STA发送的请求消息，从接入控制器AC获取关于STA附近的一个或多个AP的信息，并向STA发送通知消息，使得STA基于主动扫描 在服务集标识符SSID上发现对应的AP。

Abstract: A communication method and a communications apparatus are applied to discrete narrowband communication information. In a communication method, comprising: sending, by a network device, first indication information to a terminal, wherein the first indication information comprises a frequency channel number of a start sub-band in all discrete sub-bands of a serving cell in which the terminal is currently located, a bitmap representing whether each sub-band in a frequency band belongs to the serving cell, and a frequency spacing between sub-bands in the frequency band, wherein the frequency band is a frequency band to which all the discrete sub-bands of the serving cell belong; and sending, by the network device, second indication information to the terminal, wherein the second indication information is used to indicate a sub-band available to the terminal in all the discrete sub-bands of the serving cell.
