A method includes, within a Graphical User Interface (GUI), displaying a contact list and a conversation container to a user, the contact list including a plurality of contact objects, the conversation container being an active object used to represent an ongoing conversation, receiving input from a user through the GUI, the input instructing the client computing system to move a first contact object from the plurality of contact objects over the conversation container and drop the first contact object into the conversation container, in response to dropping the first contact object into the conversation container, instructing a server to open a first communication session between the client system and a first device associated with the one of the contact objects, the first communication session being of a first media type, and engaging in communication through the first communication session with the first device.

A multimedia collaboration system that facilitates more efficient, free-flowing collaboration sessions. The role of the presenter can be exchanged among participants in a collaboration session. The multimedia collaboration system is configured so that control of a collaboration session can be exchanged freely between participants in the collaboration session. The multimedia collaboration system enables participants in the collaboration session to determine the pace and course of the session.

The present disclosure provides a method and system for managing mission critical push-to-talk (MCPTT) communication. The method includes receiving, by a floor control server, a first floor request message, from a primary floor participant, while a floor is given to a secondary floor participant and a first media transmission is performed by the secondary floor participant; in response to receiving the first floor request message, transmitting, by the floor control server, to the secondary floor participant, a first floor revoke message for stopping the first media transmission of the secondary floor participant, and transmitting, by the floor control server, a first floor grant message to the primary floor participant; and transmitting, by the floor control server, a first floor taken message to the secondary floor participant, wherein the first floor taken message includes information of the primary floor participant given the floor.

Systems and methods for facilitating collaboration between a local user or team in a meeting space and one or more remote users outside the meeting space are provided. The virtual co-location system may include, for example, an IOT device including sensors, a microphone, a beacon light, a speaker, a user control interface (e.g., including a control input adjusted by the local user, the user control interface producing an electronic control signal representing a setting of a control device), and/or a local microprocessor for executing local collaboration software. The virtual co-location systems and methods may also or alternatively include a remote computer having a remote microprocessor for executing remote collaboration software.

Systems and methods are disclosed herein for improving audio conferencing services. One aspect relates to processing audio content of a conference. A first audio signal is received from a first conference participant, and a start and an end of a first utterance by the first conference participant are detected from the first audio signal. A second audio signal is received from a second conference participant, and a start and an end of a second utterance by the second conference participant is detected from the second audio signal. The second conference participant is provided with at least a portion of the first utterance, wherein at least one of start time, start point, and duration is determined based at least in part on the start, end, or both, of the second utterance.

Various aspects of a system and method for controlling client electronic devices in a wireless local ad hoc network are disclosed. The system includes one or more circuits in a server configured to receive a plurality of speaking-slot requests from a plurality of client electronic devices for a presented content. A client electronic device is selected based on an acceptance of a corresponding speaking-slot request. The acceptance of the corresponding speaking-slot request is based on at least an analysis of the one or more image frames of a user associated with the client electronic device and a context of the presented content. At least an audio stream provided by the user is received from the selected client electronic device. The selected client electronic device is controlled based on one or more parameters associated with at least the selected client electronic device.

The present disclosure provides a method and system for managing mission critical push-to-talk (MCPTT) communication. The method includes receiving, by a floor control server, a first floor request message, from a primary floor participant, while a floor is granted to a secondary floor participant and a first media transmission is performed by the secondary floor participant; in response to receiving the first floor request message, transmitting, by the floor control server, to the secondary floor participant, a first floor revoke message for stopping the first media transmission of the secondary floor participant, and transmitting, by the floor control server, a first floor grant message to the primary floor participant; and transmitting, by the floor control server, a first floor taken message to the secondary floor participant, wherein the first floor taken message includes information of the primary floor participant granted the floor.

A central unit for a digital conferencing system comprises a processing unit arranged for receiving a plurality of first control signals from a plurality of interpreter desks and indicating which interpreter channel is selected on an interpreter desk, and for identifying, based on the first control signals, which interpreter is interpreting in which interpreter channel and arranged for returning to and displaying on the plurality of interpreter desks a plurality of feedback signals. The central unit is arranged for receiving a plurality of second control signals from a plurality of listening units, and indicating which audio channel on a listening unit of the plurality of listening units is selected, for deriving, based on the plurality of second control signals, a total of listeners per listening channel and for sending to and displaying on the plurality of interpreter desks, information on the total of listeners per listening channel.

A system for providing alarm triggered communications is described. The system receives a notification regarding an alarm condition, and opens a communications channel based on the alarm condition. The communications channel joins together communications badges worn by caregivers in a clinical care environment. The system closes the communications channel when the alarm condition is resolved.

The present disclosure relates to method performed by a mission critical push-to-talk (MCPTT) server, the method comprises: receiving, from a first user equipment (UE), a request for a connection to communicate with one or more second UEs, wherein the request includes at least a first priority score associated with a type of the connection; determining, based on the request, a second priority score corresponding to the first UE, wherein the second priority score is associated with a type information; and performing based on the first priority score and the second priority score one of: approving the request for the connection, or rejecting the request for the connection.
