Certain embodiments of the invention generally relate to lawful interception of communications for IP Multimedia System-based (IMS-based) voice over IP (VoIP). For example, some embodiments relate to interception of communications including interception for encrypted, transcoded media. A method may include identifying a network node that provides call content interception. The method may also include determining a codec type used at a location of the call content interception at the network node. The method may further include sending a matched codec of the codec type used at the location of the call content interception at the network node to a delivery function in the communications network.

Methods and systems are disclosed for supporting delay budget information in IMS systems. Requests for DBI are received by a first node, contained within a SIP message. This can be achieved by filling a feedback field within the signal with a delay budget indicator. The first node analyzes the received signal in order to determine whether DBI is being requested. Based on this analysis, a request signal is forwarded to a second node, which carries out resource reservation. The request signal can be based on a H.248:Add.req message. In this manner, DBI can be signaled and supported even without dedicated DBI messaging.

The disclosure relates to a 5th Generation (5G) or 6th Generation (6G) communication system for supporting a higher data transmission rate. The method of a first entity performing a media resource function (MRF) includes transmitting, to a second entity, a session description protocol (SDP) offer message for an SDP negotiation associated with a conference providing a plurality of 360-degree videos, and receiving, from the second entity, an SDP answer message. Wherein the SDP offer message includes a plurality of media descriptions for the plurality of 360-degree videos, and wherein, in case that a first 360-degree video of the plurality of 360-degree videos is originated from one of a plurality of sources at a conference location of the conference, a first media description for the first 360-degree video includes a content attribute for identifying a source from which the first 360-degree video is originated.

Systems and methods are provided for establishing a video conference session. The systems and methods may include receiving, from a first conference client device, a request to establish a conference session with a second conference client device; determining a first media router for forwarding, to the second conference client device, a media data stream with predetermined attributes of a plurality of first media data streams generated by the first conference client device; determining a second media router for forwarding, to the first conference client, a media data stream with predetermined media attributes of a plurality of second media data streams generated by the second conference client device; and transmitting, to the first conference client device, a first address associated with the first media router and a second address associated with the second media router.

An electronic device includes at least one wireless communication module at least one processor connected to the wireless communication module, and a memory connected to the processor and configured to store instructions executable by the processor. The processor is configured to, during transmission of a first data frame including first data through a first resource unit (RU) on a first time resource, in response to detecting second data being enqueued in a transmission queue, transmit a second data frame including the second data through a second RU on a second time resource overlapping the first time resource during the transmission of the first data frame, using the wireless communication module. The first data frame and the second data frame may be included in a physical layer protocol data unit, and a start time of the second time resource may be different from a start time of the first time resource.

An electronic device and a method of operating the same are provided. The electronic device includes a communication circuit configured to transmit or receive data using a call channel established through a call connection with an external electronic device, and a processor configured to transmit content, which is pre-processed using a first transmission filter, to the external electronic device through the call channel, receive a first real-time control protocol (RTCP) message transmitted by the external electronic device through the call channel, identify a status of the call channel, based on the first RTCP message, determine whether or not to perform an operation of pre-processing the content to be transmitted to the external electronic device using a second transmission filter, transmit a second RTCP message using the second transmission filter to the external electronic device, and perform transmission of the content, based on the second transmission filter.

In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource.

The invention relates to a method for streaming and reproducing applications (apps) via a particular telecommunications system. The invention also relates to a telecommunications network. The invention further relates to the use of a telecommunications network of this type for streaming and reproducing applications (apps) via a particular telecommunications system. The invention furthermore relates to an application which makes it possible to configure the download, installation and updating of data on a terminal such that the whole application is fully executable on the terminal while downloading, installing and updating takes place on the terminal.

Embodiments of the present application describe techniques of facilitating directing operations. The techniques comprise obtaining guest information of a target studio, where the guest information includes a room identification number of a guest room, the guest room associated with producing content scenes; generating a directing configuration file based on the guest information of the target studio; and sending the directing configuration file to a director terminal associated with content directing, so that the director terminal performs a directing operation based on the directing configuration file.
