Telephone message-leaving method for mobile communication terminal

The invention discloses a telephone message of a mobile communication terminal, including the following steps: a) preset sound files is stored in a memory of the mobile communication terminal; b) the broadcasting mode is entered, and when the mobile communication terminal receives incoming call signals, a CPU (Central Processing Unit) sends out instructions to get through the telephone, turn off a microphone and write the preset sound files in a voice channel to transmit to a calling mobile communication terminal; c) the recording mode is entered, and the CPU sends out instructions to turn on a recording module to record calling voice; simultaneously, the outside broadcasting mode is entered according to the user choice, and the microphone is turned on and the calling voice is broadcasted; d) after the call is over, recording is stopped and the recorded voice is stored in the storage equipment. The invention realizes the function of message recording at the mobile communication terminal, thereby reducing the user cost; the voice content of the calling party can be received by a loudspeaker while message recording so as to judge whether a call is needed, which is more convenient and controllable for the users.

Lora gateway with adaptive channel function and network system based on lora gateway

The invention discloses a LoRa gateway with a channel self-adaption function and a network system based on the LoRa gateway. The LoRa gateway is additionally provided with a LoRa broadcast radio frequency module, the LoRa broadcast radio frequency module works in a broadcast channel, and under control of a processor, the LoRa broadcast radio frequency module intermittently sends out LoRa broadcastfor the LoRa gateway and intermittently receives external LoRa broadcast, wherein the external LoRa broadcast is LoRa broadcast sent out by other LoRa gateways, and the LoRa broadcast contains information of a wireless channel which is occupied by a LoRa interaction radio frequency module of the LoRa gateway at present to serve as a working channel; and the processor selects a wireless channel which is not occupied by the LoRa gateways sending out the external LoRa broadcast at present to serve as the working channel of the LoRa interaction radio frequency module. The LoRa gateway has a channel self-adaption function and can avoid the problem that due to the fact that the adjacent LoRa gateways use the same wireless channel competitively, communication of both of the two LoRa gateways fails, so that the communication efficiency of a network formed by the LoRa gateways is greatly reduced.
