Abstract: Disclosed are a Digital Enhanced Cordless Telecommunications (DECT) base station, a handset and a communication system. The DECT base station is installed with at least two different voice codecs and is configured to sequentially judge whether the voice codecs of the DECT base station match voice codecs of a handset according to a first codec information data packet sent by the handset, and when a matching is successful, send a response information to the handset to perform voice communication with the handset through a matched voice codec. By using the DECT base station can guarantee the normal voice communication between the DECT base station and the handset in the condition of installing voice codecs in the DECT base station.

Abstract: Disclosed are an alarm method and apparatus for a digital enhanced cordless telecommunications (DECT) terminal, and a storage medium. The method includes: when an alarm function of the DECT terminal is triggered, recording an account of the DECT terminal, matching an emergency contact based on the account of the DECT terminal, and establishing alarm communication with the emergency contact; and after establishing the alarm communication between the DECT terminal and the emergency contact, sending location information of a network base station connected to the DECT terminal to a device of the emergency contact, such that the device of the emergency contact obtains an alarm call of the DECT terminal and displays the location information of the network base station connected to the DECT terminal.

Abstract: The present disclosure provides a multipath device working system, including a processor and a touch display module, a control management module, a wireless communication module, a USB module, a microphone, and a loudspeaker that are respectively connected to the processor. The touch display module is configured to display a user operation interface and obtain a control instruction from a user. Both the wireless communication module and the USB module are configured to perform data transmission between the multipath device working system and an external communication device. The control management module is configured to manage a plurality of software communication terminals on the external communication device. The processor is configured to separately perform data processing on data transmitted by the touch display module, the control management module, the wireless communication module, the USB module, the microphone, and the loudspeaker.

Abstract: An earpiece includes a housing, a sound transmission component, a sound reception component, a force application structure and a trigger. A cavity is formed in the housing. The sound transmission component is provided in the cavity. The sound reception component is provided on the housing, and can move along a predetermined path. At least a retracted position and a stretched position are arranged on the predetermined path. The force application structure is connected to the sound reception component, and configured to drive the sound reception component to move to the retracted position or the stretched position. The earpiece in the present disclosure stretches out or retracts the sound reception component automatically. The earpiece in the present disclosure does not need the user to stretch out or retract the sound reception component manually, with good user experience.

Abstract: An abnormality monitoring system based on a roaming system, including a monitoring host, a mobile device terminal, and a roaming device group, where the roaming device group includes a cluster service host and several roaming hosts; and any one of the roaming hosts is configured to: receive real-time data uploaded by the mobile device terminal; determine, through analysis, whether the real-time data is normal or abnormal; and when determining that the real-time data is abnormal, send a solving policy to the mobile device terminal; or if a solving policy corresponding to the abnormal real-time data cannot be found, report the abnormal real-time data to the monitoring host, and after receiving a solving policy fed back by the monitoring host, send, to the mobile device terminal corresponding to the abnormal real-time data, the solving policy fed back by the monitoring host.

Abstract: Disclosed are a method and apparatus for improving a signal-to-noise ratio of a microphone signal. The method includes: selecting a target microphone to be improved as a first microphone, and selecting a microphone whose signal-to-noise ratio is greater than a signal-to-noise ratio of the first microphone and exceeds a preset first threshold as a second microphone; and adding, by an adder, a voice signal of the first microphone and a voice signal of the second microphone in a case that a same voice signal is inputted, to obtain a first microphone signal whose signal-to-noise ratio has been improved.

Abstract: Disclosed are a connection method and apparatus that are applied to a user terminal. The method includes: obtaining positioning information of a host in a conference room, where the positioning information includes an Internet Protocol (IP) address, point to point (P2P) information, and access point (AP) information of the host in the conference room; establishing a local area network (LAN) connection to the host in the conference room based on the IP address; when the LAN connection between the user terminal and the host in the conference room fails to be established, establishing a wireless fidelity (Wi-Fi) P2P network connection to the host in the conference room based on the P2P information; when the Wi-Fi P2P network connection between the user terminal and the host in the conference room fails to be established, establishing an AP-station connection to the host in the conference room based on the AP information.
