The present invention provides a method for notifying Multicast Broadcast Single Frequency Network (MBSFN) subframe configuration, which comprises the following steps: a first node sends its MBSFN subframe configuration, via an X2 interface, to a second node with which the first node is connected; the first node receives the MBSFN subframe configuration of the second node as a feedback. According to the invention, a serving cell can obtain the MBSFN subframe configurations of the neighboring cells and/or RNs, so that rational utilization of resources is achieved according to the configurations. Therefore, interference between cells is reduced, and system capacity and efficiency are improved.

An internet of things (IOT) system includes an IOT server and multiple IOT devices and a voice-controlled device connected to the IOT server and the multiple IOT devices. The voice-controlled device receives a voice-controlled message of environmental sound information through a voice control interface, and broadcasts the voice-controlled message to neighboring IOT devices to drive a corresponding IOT device according to the voice-controlled message. When failing to recognize the voice-controlled message, the voice control interface uploads the voice-controlled message to a cloud server for query through the IOT server, and broadcasts a result of the query returned from the cloud server. A way of chain broadcasting is employed by the voice-controlled device to drive selected IOT device or receive returned information so as to enhance operational convenience in using IOT devices.

The present disclosure provides a wireless network coverage enhancement method, apparatus, and system. The method includes: receiving, by a terminal, a downlink signal sent by a network device; determining, by the terminal, a first coverage level of the terminal according to the downlink signal; determining, by the terminal, an uplink communications parameter according to the first coverage level; and sending, by the terminal, an uplink signal to the network device according to the uplink communications parameter. According to the method in embodiments of the present invention, a probability of successfully receiving the uplink signal is improved. Therefore, the network device does not need to send a NACK to the terminal, so that overheads of an air interface between the terminal and the network device are reduced, a period in which the terminal performs coverage enhancement is shortened, and power consumption of the terminal is reduced.

A wireless access setting device is disclosed. The wireless access setting device includes a wireless access point and a wireless access controller connected thereof. The wireless access point broadcasts target identification data, and the wireless access controller presets pairing data for the target identification data corresponding to virtual local area networks (VLANs). When a wireless communication device receives the target identification data, the wireless communication device transmits its first media access control address to the wireless access point according to the target identification data to store them. The wireless access point transmits its second media access control address, the first media access control address and the target identification data corresponded thereof to the wireless access controller to store them, there by cooperating with the pairing data to control the wireless communication device and the corresponding VLAN to transmit packets through the wireless access point.
