Method, server, network node and multimedia User Equipment, UE, for controlling communication session establishment (10) in a multimedia over Internet Protocol, IP, based communications network with a plurality of multimedia UEs registered in the communications network with a same subscriber. In a communications handling server of the network, in reply to the receipt (12) of a request (11) for establishing a communication session with at least one UE of the plurality of UEs, an adapted request (13) is provided, based on which provisional response(s) and which final response(s) the UE of the plurality of UEs may provide, in response to the request (11) for establishing the communication session. The adapted request is forwarded (14) in the communications network, and a receiving UE processes the adapted request for establishing or not establishing the communication session (15).

Technologies for casting digital media content include a source computing device communicatively coupled to a destination computing device. The source computing device is configured to transmit a set of identifiers of the source computing device to the destination computing device and receive a set of identifiers of the destination computing device from the destination computing device. Each set of identifiers includes a version (e.g., hardware or software) associated with the respective computing device and a unique identifier of the respective computing device. The source computing device is additionally configured to determine a subset of casting session parameters from a set of casting session parameters based on the one or more capabilities of the destination computing device which are usable by the destination computing device to establish a casting session and stream digital media content in accordance with the subset of casting session parameters. Other embodiments are described and claimed.

The present disclosure provides a voice signaling transmission method and device. The voice signaling transmission method includes: sending, by a second device, a request signaling to a first device; receiving, by the second device, a signaling for requesting the second device to try a call sent by the first device, and sending a signaling for trying a call to the first device; receiving, by the second device, a ringing signaling sent by the first device and sending a temporary response signaling to the first device; and receiving, by the second device, a signaling for confirming the response and a signaling for confirming the request which are sent by the first device and sending a response signaling to the first device.

A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

In various aspects, a system that receives a first message, wherein the first message comprises a communication device identification and a feature tag having a language indication that indicates a language configuration of a user equipment. In response to the receiving the first message, storing the language indication and associating the language indication with the communication device identification. The system determines whether an incoming call is not authenticated and in response to the determining that the incoming call is not authenticated, transmitting a textual message to the communication device using the language configuration to indicate the incoming call is not authenticated.

Described herein are techniques, devices, and systems for handling Session Initiation Protocol (SIP) messages with malformed header fields. A communication device that receives a SIP message from an additional communication device may identify one or more identified header fields of a plurality of first header fields in a message header of the SIP message that correspond to (e.g., match) one or more second header fields in a list of second header fields accessible to the communication device. If the communication device determines that the one or more identified header fields are not malformed, the communication device may process the SIP message without regard to remaining header fields in the message header. If, however, the communication device determines that at least one identified header field of the one or more identified header fields is malformed, the communication device may reject the SIP message.

Disclosed are a video call switching method, a storage medium and a terminal. The method comprises: upon receiving a video call request initiated by a caller terminal and in a video call state, acquiring a first communication type of the current video call and a second communication type of a video call initiated by the caller terminal; if the first communication type is different from the second communication type, giving a prompt of the video call request initiated by the caller terminal; and when a response operation for the video call request is received, switching the current video call to the video call of the second communication type.
