5 results about "Group communication systems" patented technology

A group communication method, a group communication apparatus, a base station, a terminal, a group communication system and a computer-readable storage medium. The method is executed by a radio-frequency daughter board of a base station, and comprises: sending a synchronization frame to a terminal group within a communication cycle, wherein the synchronization frame includes indication information that indicates whether the communication cycle is a wake-up packet sending cycle, the terminal group comprises a plurality of terminals, and the plurality of terminals are grouped in a multi-level organization manner (S110); and within the wake-up packet sending cycle, sending to the terminal group a multi-level description field for waking up terminals and a data payload field (S120).

Provided in the embodiments of the present application are a cross-domain intercom group communication system, method and apparatus, and a device and a medium. In the present application, a first quantum security software development kit sends to a first quantum key system a key application request for the communication of a group, receives first authentication code information and a key identifier that are sent by means of the first quantum key system, and sends group information of the group, the first authentication code information and the key identifier to a second quantum security software development kit; the second quantum security software development kit sends an identity token of the second quantum security software development kit, the group information, the first authentication code information and the key identifier to a second quantum key system; the second quantum key system determines verified authentication code information; and a second intercom terminal establishes communication with a first intercom terminal by means of the verified authentication code information, such that the first intercom terminal and the second intercom terminal can communication with each other even if they are terminals in an intercom group of a cross-domain quantum resource pool.

The invention relates to a group communication system (1) comprising: at least one WLAN wireless network, a plurality of terminal devices (E1-E3), and a plurality of access points (AP1-AP3), wherein each of the access points (AP1-AP3) forms a node of the group communication system (1), wherein several or all of the access points (AP1-AP3) form a WLAN mesh wireless network (2), wherein each of the terminal devices (E1-E3) is connected to the access point (AP1-AP3) with which the best quality WLAN wireless connection exists, wherein each of the terminal devices (E1-E3) is a participant in a group communication that encompasses the entire WLAN mesh wireless network (2), and wherein participation in the group communication occurs regardless of which access point (AP1-AP3) the respective terminal device (E1-E3) is connected to.

Medium, method and system for ad hoc, ambient, synchronous multimedia collaboration in a group-based communication system. Embodiments of the invention provide a way for users to quickly establish a real-time collaboration among a group of peers without the burden and overhead of a conventional call or video meeting. Users can quickly and easily join and leave these synchronous multimedia collaboration sessions at any time, without disrupting the session for other users. This enables the user to experience the collaboration as a convenient forum rather than a burdensome scheduled event.
