A system and method to leverage Web Real-Time Communication (WebRTC) for implementing Push-to-Talk (PTT) solutions. One or more servers interface to a communications network to perform advanced voice services for one or more wireless or wired user devices, wherein the advanced voice services include a two-way half-duplex voice call within a group of the user devices comprising a PTT call session. At least one of the user devices communicates with at least one of the servers during the PTT call session using a WebRTC connection, and at least the media streams for the PTT call session are transmitted between the server and the user device using the WebRTC connection.

A group detail indicator is provided that relates to group communication in a communication system. The group detail indicator provides information on at least an identity of a group and a type of the group. The group detail indicator also is attached to one of a request to initiate a group communication session and an instant messaging request.

A radio communication system integrating voice radio signals with an audio-video conference session that includes at least one two-way radio configured to wirelessly transmit and receive voice radio signals with a radio control station, a radio communication controller comprising a first audio interface, a second audio interface, and a radio control processor, and configured to transmit and receive audio signals with the radio control station through the first audio interface, and an audio-video conferencing system configured to transmit and receive audio signals with the radio communication controller through the second audio interface. A voice radio channel of the at least one two-way radio is provided to the audio-video conferencing system through the radio control station and the radio communication controller to participate in the audio-video conference session.

An electronic communications device including a transceiver, a touch screen display, and an electronic processor and a method for controlling same. The method includes generating, with the electronic processor, a graphical user interface including a soft push-to-talk button and a call hang time indicator, indicating visually a call hang time, in proximity to the soft push-to-talk button. The method also includes displaying the graphical user interface on the touch screen display, receiving, from the touch screen display, a first input selecting the soft push-to-talk button, and, in response to receiving the first input, establishing a push-to-talk channel via the transceiver.

A first wireless device transmits to a second wireless device, a SIP REGISTER message comprising a first Contact header field comprising an internet Protocol multimedia subsystem (IMS) identifier identifying a mission critical video capability of the first wireless device. The second wireless device transmits to an IMS network entity, a second SIP REGISTER message comprising a second Contact header field comprising the IMS identifier. The IMS network entity identifies a mission critical application server (MC AS) and registers the first wireless device to the MC AS. The MC AS: receives a SIP request from the IMS network entity for the first wireless device; determines that a mission critical video service can be established employing the SIP request and the mission critical video capability; and transmits the SIP request to the first wireless device via the second wireless device.

A system includes a server including first circuitry and a plurality of terminals, each of which includes second circuitry respectively. The first circuitry is configured to store primes assigned to the plurality of terminals, acquire two or more primes assigned to two or more terminals that and are destinations of contents, calculate a first product of the two or more primes, and transmit first notification data including the first product and the contents to the plurality of terminals. The second circuitry is configured to store an assigned prime, receive the first notification data, determine whether the first product included in the first notification data is divisible by the assigned prime, and acquire, from the first notification data, the contents included in the first notification data based on a result of a determination.

Methods and apparatus for providing a messaging server within a premises device e.g., a home or enterprise gateway device. In one embodiment, a system is described that includes a premises device that acts as a centralized client messaging platform providing messaging services between a content provider and client devices, and also between client devices within a premises network. The premises device enables client-to-client communication that bypasses the long trip and propagation delay over the Internet by connecting the message across the premises network within the home or building. The premises device enables messages to be communicated between a content provider outside the premises network and the client devices via a single connection to minimize the number of Internet connections that need to be opened, and the number of messages communicated with servers outside of the premises network via both upstream aggregation and downstream dis-aggregation, which collectively save both network bandwidth and device reaction time.

In accordance with one or more embodiments, aspects of the disclosure provide efficient, effective, and convenient ways of uploading and authenticating content. In particular, a user device may receive validating information from a wireless networking device. The user or client device may record a content item, and may insert a validation tag based on the validating information. The user or client device may then send the content item to the wireless networking device. The wireless networking device may receive the content item at a first location and may determine the validity of the content item based on the validating information. The user device may continually interact with wireless networking devices as it travels to continually upload content items while establishing the validity of the time and location of the content items.

A single content region in a chat history display is used to display entries representative of a plurality of messages corresponding to all chat histories for all of chat threads currently engaged in by a given mobile terminal. Additionally, a buddy list display supports management of chat buddies, a detail view display allows otherwise truncated messages to be displayed, and a text message editor display supports the composition of text messages. Each chat user may designate public display identifiers for purposes of identification to other chat users. Additionally, each user may designate private display identifiers for each of his/her buddies, which private display identifiers may be used to replace the public display identifiers for that user's buddies when displayed on the user's mobile terminal. In this manner, the use of speech and text based group chatting and similar services in wireless communication environments is more readily enabled.
