Efficient use of channel bandwidth response, response timing, along with the ability to acquire the most accurate and up to date response are provided for management of virtual assistant search queries within a communication system (100). Improved management is obtained using an artificial intelligence (AI) server (104) controlling response activity to a query communication device (102) by incorporating one or more of: adjusting verbosity of responses (158), redirecting queries from the AI server to alternate resources (412), and/or prioritizing of a response (506) based on wait time.

A method for transmitting media between terminals, a first terminal being identified with a plurality of session servers and second terminals each being identified with at least one of the session servers. The method comprises: upon reception by a proxy server of a single media stream from the first terminal, transmitting said media stream from the proxy server to at least one of the session servers; and/or upon reception by the proxy server of a plurality of media streams, from a plurality of session servers; transmitting, to the first terminal, a single media stream selected among the plurality of media streams received.

An exemplary land mobile radio dispatch console and method are provided. In one embodiment, the console has the capability to process and handle Requests To Talk (RTT) and emergencies. In another embodiment, the console has the capability to provide a history. In another embodiment, the console provides the capability for operators to configure and save patches of predefined groups for later use. In another embodiment, the console includes a telephone interconnect interface component, and combinations of features mentioned above.

A floor control method and apparatus are disclosed. In an embodiment a floor control method includes receiving, by a server over Long Term Evolution network, a first message sent by user equipment (UE), wherein the first message comprises a parameter indicating that an event type is a floor request, generating, by the server, a second message according to a floor control policy and the first message, wherein the second message comprises a parameter indicating that an event type is floor granted and sending, by the server, the second message to the UE, wherein the second message is used to instruct the UE to notify a user of the UE that a floor is granted.

A process for controlling a plurality of mobile-radio equipped robots in a talkgroup includes receiving, at a mobile-radio equipped robot via a wireless communications interface comprising one of an infrastructure wireless communication interface for communicating with an infrastructure radio access network (RAN) and an ad-hoc wireless communication interface for communicating with an ad-hoc network, a group voice call containing a voice-command. The mobile-radio equipped robot determines that it is a target of the group voice call, and responsively text-converts the voice-command into an actionable text-based command. The mobile-radio equipped robot subsequently operates a mechanical drive element in accordance with the actionable text-based command.

A push-to-talk device is provided. The push-to-talk device includes a communication interface, a storage configured to store identification information of a plurality of push-to-talk devices included in a network group, and an operation processor electrically connected to the communication interface and the storage. The operation processor is configured to (a) designate one or more push-to-talk devices that are allowed to subscribe to a first message among the plurality of push-to-talk devices, and (b) transmit the first message to the plurality of push-to-talk devices by using a publisher-subscriber pattern through the communication interface.

In some examples, a first push-to-talk (PTT) client that has access to a wide area network (WAN) performs distributed control for a PTT session in conjunction with distributed control for the PTT session performed by another PTT client in the PTT session, the distributed control by the first PTT client performed without use of any PTT server.

A remote UE transmits a first signaling for user registration of the remote UE into an MCPTT server. The MCPTT server detects a relationship of connection between the remote UE that transmitted the first signaling and a relay UE to which the remote UE is connected. Upon receiving voice data from a UE given a floor grant, the MCPTT server determines, as a destination UE of the voice data, only one of the relay UE and the remote UE that have the relationship of connection. The MCPTT server transmits the voice data with use of a unicast bearer for the destination UE. The relay UE transmits, to all of the remote UEs connected to the relay UE, the voice data that is transmitted from the MCPTT server.

Embodiments include a system, method, and computer program product for providing seamless PTT services to a user. In an embodiment, a push-to-talk (PTT) component provides, to the user, PTT services with a talk group through a connectivity to a data channel in a mobile network. A voice monitoring component monitors attributes of data connectivity on the data channel to determine when a voice quality falls below a threshold. When the voice quality is determined to fall below the threshold, a connectivity component requests the user to switch the connectivity to a voice channel. Then, the connectivity component dials a telephone number through the voice channel to access a voice conference bridge that provides the PTT services. To provide the PTT services, the voice conference bridge sets up a routing path to a session initiation protocol session for the talk group, and routes voice communication through the SIP session.
