The present application discloses a DECT base station, handle and communication system. The DECT base station is installed with at least two voice codecs. The DECT base station is configured to sequentially judge whether the voice codecs of the DECT base station match the voice codec of the handle according to the first codec information data packet sent by the handle, and when the matching is successful, send a response information to the handle to perform voice communication with the handle through the matched voice codec. The present application may guarantee the normal voice communication between the DECT base station and the handle in the condition of installing voice codecs in the DECT base station.

The present invention concerns a base station (12) having a DECT communication module (13) for wirelessly communicating with one or more registered portable DECT devices 10). The base station also has a virtual assistant module connecting over an IP communication channel (28) to a virtual assistant providing responses to user instructions, and a telephony module connecting to and accessing a remote resource over a telephony communication channel (27). A device manager (15) identifies and stores communication parameters of the DECT devices, and can implement a user instruction communicated from a DECT device via the DECT communication module and can route virtual assistant responses to a user instruction. A broker module (19) establishes a communication link between the DECT devices and the virtual assistant, and between the DECT devices and the telephony communication channel. The broker module includes a transcoder module (17) operating to trans-code communications over the communication link between the DECT devices and the virtual assistant in the event of a disparity in communication parameters to enable communication of user instructions and responses between the virtual assistant and a DECT device.

A relay repeater network communication system includes a relay repeater and three digital walkie-talkie sets, wherein each of the digital walkie-talkie sets comprises at least one digital walkie-talkie, the relay repeater is connected to each of the digital walkie-talkies, and the relay repeater communicates with each of the digital walkie-talkies through the DECT communication method to realize the mutual communication between each of the digital walkie-talkies, thus achieving the effect of multi-person speech and multi-person listening, which is convenient for the collaborative work of people and enriches the function of digital walkie-talkies.

A USB phone supporting multi-device conference application includes: a touch display module, an audio processing module, a digital enhanced cordless telecommunications (DECT) module, a Bluetooth module, a USB interface, and an MCU controller. The Bluetooth module is configured to establish a Bluetooth communication connection with an external Bluetooth terminal; the USB interface is configured to establish a USB communication connection with an external intelligent terminal; the DECT module is configured to establish a communication connection with an external wireless headphone; the touch display module is configured to display data, and recognize and obtain a touch operation instruction; the audio processing module is configured to perform audio processing on received audio data; the MCU controller is configured to process received data, further provided with a first mixer and connected to the touch display module, the audio processing module, the DECT module, the Bluetooth module, and the USB interface.

A method for receiving audio broadcasts during a digital enhanced cordless telecommunication (DECT) frame, the method may include (a) opening, during a DECT frame and by a portable point (PP) that is a potential recipient of the audio broadcasts from a fixed part (FP), multiple reception windows that are spaced apart from each other and are allocated to receive signals related to audio broadcast; (b) receiving received signals, by the PP and during the multiple spaced apart reception windows; and (c) processing, by the PP, the received signals.

A wireless communication method and protocol for wireless RF transmission of audio data from a plurality of wireless RF devices (portable parts PP) to a wireless RF receiver device (fixed part FP) using a full slot DECT protocol. The FP broadcasts in each frame, a multiplex of control information to the plurality of PPs. The PPs receive the multiplex of control information, and extract control information intended for each individual PP from the multiplex of control information. Preferably, the PPs are synchronized to transmit audio data in respective time slots covering both time slots in first and second half of the frame. This allows a high number of PPs to be connected to one FP still at a high audio quality with low latency, since both the normal uplink and downlink parts of the DECT frame are used for audio data transmission. This allows the method to be used for a conference call system of a high number of wireless microphone devices, or a live performance wireless microphone and/or musical instrument sound system or the like.
