System and method for optimizing a transcoding session between multiple terminals are disclosed. The method determines properties of the transcoding session, including a number of terminals participating in the transcoding session, media characteristics supported by each terminal, a measure of performance of the transcoding session to be optimized, and optionally a proportion of time involved in the transcoding session for each terminal. Then a cost function characterizing the measure of performance of the transcoding session and depending on the above properties of the transcoding session is built, followed by optimizing the cost function with respect to said measure of performance to determine an optimal measure of performance for the transcoding session and optimal values for the media characteristics for each terminal. In one embodiment, codecs used by multiple terminals and computational complexity of the transcoding session are optimized. A corresponding system for optimizing the transcoding session is also provided.

Initiation of a search query is accomplished by voice direction, rather than by reading choices and texting or clicking through options. A mobile phone includes a dedicated voice query service button for generating a signal for initiating a voice enabled service session, a speaker and microphone for transducing sounds and electrical signals, a display for displaying visual information to a user, memory for storing data, a transceiver for receiving and transmitting data and a processor. The processor receives a signal generated by the service button for initiating a voice enabled service session, communicates a prompt to a user to begin speaking, stores voice data from a user and transmits the stored voice data to a server for transforming the voice data to a result satisfying the spoken voice service request.

The present disclosure is related to technology for a sensor network, machine to machine (M2M) communication, machine type communication (MTC), and Internet of Things (IoT). Provided is a method, performed by a server, of transmitting and receiving data, in which, as a transmission authority request is received from at least one terminal from among a plurality of terminals connected to the server, a number of transmitting terminals previously determined by the server is compared with a maximum number of transmitting terminals allowable by the server, in response to the transmission authority request, and a transmission authority of the at least one terminal is determined based on a result of the comparing. The present disclosure are applicable to intelligent services based on the technology (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security, and safety-related service).

Methods and systems for managing control data in a push-to-talk over cellular (PoC) communication are provided. A method includes: receiving, by a user equipment (UE), control data from a PoC server on a control plane and/or a data plane for a PoC session. The control data is not limited to a text control data, but also can include an audio control data and/or an image control data. Further, the method includes processing the received control data and sending the processed control data from a communication processor (CP) to an audio device and/or an always on display of the UE through a direct communication channel set up between the CP and a low power processor (LPP), without waking up an application processor (AP) of the UE. Thus, the method effectively reduces battery consumption of the UE to lowest possible level.

Typically, the service area is a wide area that is physically inaccessible via ground transportation. In addition, embodiments include the formation of a decentralized mesh supernetwork comprising two or more dynamic wireless aerial mesh networks where each dynamic wireless aerial mesh network is owned by a different agency (e.g., a secure community). A member of a first dynamic wireless aerial mesh network may send a request to a member of a second dynamic wireless aerial mesh network for the first dynamic wireless aerial mesh network to join the second dynamic wireless aerial mesh network to form a mesh supernetwork, and receive an acceptance from the member of the second dynamic wireless aerial mesh network.

Implementations disclose a notification delivery mechanism for present viewing users. A method includes identifying a notification to be sent to a user having a plurality of user devices; determining presence of the user on a first user device of the plurality of user devices; determining whether a media player on the first user device is playing media content; and upon determining that the media player on the first user device is playing the media content, transmitting the notification to the first user device without transmitting the notification to other user devices of the plurality of user devices.

A method of wireless communication is disclosed, in which a wearable device may determine whether a network operator provides support for bursty communication, and communicate directly through the network operator in the bursty communication in response to the determining the network operator provides the support for bursty communication. The support for bursty communication by the network operator may be either integrated into a telephony application server (TAS) or a wearable application server (WAS) that is a separate entity from the TAS and deployed between the TAS and the wearable device. The bursty communication by the wearable device may include receiving packets in the bursty communication, buffering the received packets, and transmitting or playing out the bursty communication in entirety after all of the packets in the bursty communication have been received. Apparatus corresponding to such method is also disclosed.

Apparatus for controlling push-to-talk communication over a professional mobile radio includes a control portion including a first optical transceiver portion for converting an optical downlink signal into an electrical downlink signal for presentation to a user and for converting an electrical uplink signal into an optical uplink signal for provision to a radio portion; one or more interface portions, each connected to the control portion by an optical link, each connectable to a respective radio portion by electrical connection, which radio portion enables communication via a respective wireless communication link over one or more communication channels, each interface portion including a second optical transceiver portion for converting a downlink signal received from the respective radio portion as an electrical signal into the optical downlink signal for provision to the control portion and for converting the optical uplink signal into an electrical uplink signal for provision to the respective radio portion.

[Problem] To provide a voice communication system which causes a relaying device to manage communication between terminal devices based on the affiliations of the terminal devices, and manage the current positions of the respective terminal devices. [Solution] In a voice communication system, a relaying device relays voice communication of a plurality of section systems. The relaying device stores, with respect to each of the section systems, a plurality of pieces of area information divided on the basis of the communication range of a wireless access point. A terminal device transmits a voice signal to which the identification code thereof is added. When receiving the voice signal from the terminal device, the relaying device identifies a section system to which this terminal device belongs from the identification code added to the voice signal, and identifies an area in which the terminal device is present on the basis of positional information relating to the terminal device. The relaying device transfers the voice signal to another terminal device which belongs to the identified section system and is present in the identified area.
