The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an IMS (Internet Multimedia Subsystem) AS (Application Server) in a wireless communication system, the method comprising: receiving a first message including a first SDP (Session Description Protocol) offer for a first media from a first user equipment (UE) from a first UE; transmitting a second message for notifying a media change request event to a data channel signaling function (DCSF) entity; receiving a third message including avatar media processing information from the DCSF entity; and transmitting a fourth message including a second SDP offer for a second media from a network entity to a second UE.

Aspects of the subject disclosure may include, for example, a device in which a processing system defines service attributes for a function of an internet multimedia subsystem (IMS) core; the function is dedicated for providing a service to a user endpoint (UE) device. The processing system facilitates constructing a resource profile of the IMS core that includes the function; registering the function at a network repository function (NRF) associated with the IMS core; discovering the function from the NRF; obtaining a service requirement of the UE; and matching the service requirement with the service attributes in accordance with matching criteria. Other embodiments are disclosed.

The present invention relates to the technical field of Internet multimedia services, and proposes an adaptive bitrate selection method and system for dynamic bitrate videos, which includes the following steps: Initialize all available bitrate information and video chunk information; When receiving a user request to play a dynamic bitrate video, collect the environmental state parameters of all currently available bitrates, and pass the environmental state parameters into the MAB algorithm. The MAB algorithm calculates the optimal bitrate based on its own parameters and the environmental state parameters; After downloading the corresponding video chunks according to the optimal bitrate, play the video through a video player, and calculate the actual reward of this play; Update the own parameters of the MAB algorithm corresponding to the bitrate according to the actual reward of this play, and apply it to the decision-making of the next optimal bitrate. The present invention can maintain the optimal decision when the user's network environment changes frequently, thereby avoiding affecting the user experience.

The invention relates to the technical field of internet multimedia, in particular to a unicast and multicast collaborative live broadcast stream processing method and system. Comprising the following steps: an edge CDN node simultaneously initiates unicast and multicast requests to a source CDN node; the edge CDN node judges the source of the first live stream data from the source CDN node: when the source is from multicast, a unicast request is disconnected, and multicast service data is stored in a first cache region of the edge CDN node to directly serve a user; when the source is from unicast, storing unicast service data into a first cache region of the edge CDN node to directly serve the user; storing the multicast service data into a second cache region of the edge CDN node until the unicast service data in the first cache region is overlapped with the multicast service data in the second cache region, and disconnecting the unicast request; and merging all the multicast service data in the second cache region into the first cache region, deleting the second cache region, storing the subsequent multicast service data into the first cache region, and using the multicast service data to serve the user.

According to one embodiment, a method for continuing an Internet Multimedia Subsystem session between a first mobile terminal and a second mobile terminal in case of a handover the first mobile terminal from a source serving satellite to a target serving satellite is described. The method comprises receiving, by an Internet Multimedia Subsystem Application Server, a message comprising an identification of the target serving satellite and sending, by the Internet Multimedia Subsystem Application Server, in reaction to reception of the message, a re-invite message to an Internet Multimedia Subsystem entity serving the second mobile terminal.
