Disclosed are a communication device having a base station function of a Digital Enhanced Cordless Telecommunications (DECT) cellular system, and a communication system. The communication device includes an IP phone and a DECT adapter. The IP phone is connected to the DECT adapter, to form a base station; and the DECT adapter is configured to wirelessly communicate with at least one cordless handset via DECT, so as to register information of the at least one cordless handset with the IP phone. The present application enables the IP phone to be externally connected to the DECT adapter to support a DECT mode, so that the IP phone possesses a base station function of a DECT cellular system. It is not required to deploy multiple different systems. Such an IP phone and other base stations can form a Multi-Cell DECT system, expanding the coverage of a DECT signal.

A DECT network clustering method includes sending, by a DECT host to a router, a multicast command that declares joining a specified multicast group; sending, by a DECT device to the router, a multicast probe message sent to a target multicast group; receiving, by the router, the multicast command and the multicast probe message, and sending, to the DECT host according to the multicast command, the multicast probe message; receiving, by the DECT host, the multicast probe message, and sending status declaration information to the DECT device; receiving, by the DECT device, the status declaration information, and initiating a TCP connection request to the DECT host in a point-to-point manner; and receiving, by the DECT host, the connection request from the DECT device, and establishing a TCP channel with the DECT device.

The present application discloses a media interaction method in a Digital Enhanced Cordless Telecommunications (DECT) network cluster. Communication with a DECT host is established through a DECT network cluster constructed in advance, to obtain first account information allocated by the DECT host, and information of a first call request to call a second account is sent to the DECT host, so as to make a call to the second account in a first communication manner. If no Real-time Transport Protocol (RTP) from the second account is received, information of a second call request to call the second account is sent to the DECT host, so as to make a call to the second account in a second communication manner. Embodiments of the present disclosure can solve the technical problem of a communication failure and reduce a waiting time for communication, thereby achieving optimal Voice over Internet Protocol (VOIP) call experience.

A network device for an intercom network for duplex audio communication between users of the intercom network has a housing and a communication module in or at the housing and that can establish a radio link for transmitting audio signals to and receiving audio signals from another user. The radio link is subject to the DECT protocol or another protocol, and the audio signals to the communication module is broken by reflection into a plurality of radio paths. Multipath interference is prevented or reduced by electronic elements including at least one equalizer for processing a plurality of audio signals received along the plurality of radio paths and performing a signal correction.

A headset system comprising a headset and a base station. Each of said headset and base station comprises a transceiver configured to transmit radio signals between said headset and said base station according to a first wireless communication protocol, and each of said headset and base station further comprises a transceiver configured to transmit radio signals between said headset and said base station according to a second wireless communication protocol. At least one of said headset and said base station further comprises selecting means, such as a protocol selector configured to select one of said first and second wireless communication protocols for transmission of radio signals between said headset and said base station. The protocol selector is adapted to select the first wireless communication protocol for transmission of voice communication and the second wireless communication protocol for transmission of media content.

A telecommunications system includes a base, a plurality of handsets, and a status database for storing status information. Each handset is localized to the base. The status information may be that of a first handset of the plurality of handsets. The base broadcasts to the plurality of handsets a status broadcast that includes the status information.

A headset adapter and a headset system for voice communication comprising a headset and a headset adapter as well as a method of enabling microphone transmission to a host device are provided. The headset comprises at least one earphone having a headset speaker, a headset microphone and a headset transceiver, the headset adapter being configured to interconnect the headset and a host device, the headset adapter comprising an adapter processor, a host interface, such as a host interface interconnecting the adapter processor and the host device, an adapter transceiver configured to establish a wireless communication link with the headset. The adapter furthermore comprises a controller configured to enable and disable the headset microphone. The adapter processor is configured to receive a request for headset microphone activation or microphone deactivation, for example from the host interface, and in response to receiving the request providing a control signal to the controller to enable or disable the headset microphone. The controller may thus activate the transceiver to configure the wireless communication link with the headset.
