The present application discloses a streaming media data processing method, including: receiving streaming media data, initializing a storage file and a storage queue according to a header data packet of the streaming media data, and starting a first thread to receive an enqueuing operation; starting a second thread and establishing a message channel to read a streaming media data packet from the storage queue for parsing, and adding the parsed streaming media data packet into the message channel in the form of a message; starting a third thread to read the message from the message channel and encapsulating the message according to preset requirements so as to store the message on a disk; determining a target pull server corresponding to the streaming media data and publishing the streaming media data to the target pull server.

A method and device for pushing a multimedia resource and a display terminal, the method including: obtaining, by a cloud server, a device identifier of a mobile terminal upon determining that the mobile terminal has established a connection with a display terminal; searching with the device identifier a device identifier information table for multimedia resource play information corresponding to the device identifier; determining multimedia resources to be played according to the multimedia resource play information; and transmitting the multimedia resources to be played to the display terminal.

An embodiment method includes receiving, by a first push-to-talk (PTT) service hosted on a processor, a session initiation request from a PTT client of a user and identifying, by the first PTT service, a user affinity group of the user. The user is assigned to the user affinity group in accordance with a prediction the user will communicate with first users in the user affinity group more frequently than second users in different user affinity groups. The method further includes determining, by the first PTT service, a PTT call server for the user affinity group. The PTT call server serves the user and the first users belonging to the user affinity group.

A method for remotely controlling a server includes: receiving a push message, in which the push message represents that an operation of the server is suspended; showing a control interface on a screen of a cellular phone when receiving a user's click command; and when receiving a user's control command from the control interface, transmitting a control signal to the server according to the user's control command, in which the control signal is used to inform the server about a following strategy of the operation, to make the server continue performing the operation or terminate the operation.

A method, Group Application Server, and mobile device are provided that coordinate an operation of multiple mobile devices of a same user in a group call. When the multiple mobile devices join the group call, a first mobile device of the multiple mobile devices determines that it is an active device and provides an indication of such to the Group Application Server. In response to receiving the indication, the Group Application Server identifies a second mobile device, of the multiple mobile devices, that is a non-active device and one or more of modifies subsequent communications with the second mobile device or conveys a behavior modification message to the second mobile device. In another embodiment of the present invention, the first mobile device may indicate that it is the active device directly to the second mobile device and the second mobile device modify its behavior accordingly.

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.

A telephone call is elevated to a virtual meeting while maintaining the telephone call as an audio channel of the virtual meeting for an audio-only caller. During a telephone call, one of the participants of the telephone call requests to switch the telephone call to a virtual meeting. To enable an audio-only caller participating in the telephone call to switch to the virtual meeting, a message is transmitted to the phone device of the audio-only caller. Responsive to an interaction with the message at the phone device, the phone device is connected to the virtual meeting in which the telephone call is maintained as the audio channel at least for the audio-only caller. The specific form and content of the message is based on whether a client application associated with a web service used to implement the virtual meeting is installed on the phone device.

A method for transmitting a stream includes: receiving a streaming request from a stream receiver, in which the streaming request includes a stream identifier and a type of the stream receiver; obtaining an encapsulated stream by performing protocol encapsulation on a stream corresponding to the stream identifier based on a streaming protocol corresponding to the type; and transmitting the encapsulated stream to the stream receiver.

System, method, and apparatus for Internet Protocol (IP) based radio communications. One or more browser-based dispatch consoles connect to one or more Radio over IP (RoIP) gateway device over an untrusted network (e.g., the public Internet) using a Web Real-Time Communication (WebRTC) connection secured with SSL/TLS. Each RoIP gateway device provides an analog interface to the radio domain so as to communicate with one or more radio. This architecture avoids any ongoing connection to a centralized cloud-based server and maintains secure radio communications over the untrusted network. Each browser-based dispatch console accesses each RoIP gateway device from a standard web browser thus enabling portability across any platform that supports a browser.

A wireless device determines a change in a signal quality measurement of a wireless network. In response to the determining, a first message for changing one or more media for a video call in the wireless network is transmitted from the wireless device to a video application function (AF). A policy and charging rules function (PCRF) receives from the video AF, a DIAMETER AA-request (AAR) command for modifying a quality of service (QoS) of the video call. The PCRF transmits to a policy and charging enforcement function (PCEF), a second message comprising an updated QoS, wherein the updated QoS comprises QoS data bearer modification information based on the change in the signal quality measurement of the wireless network. The PCEF implements the updated QoS for the video call.
