Method, apparatus, and system for processing continuity of media streams in a session

A method for processing continuity of media streams in a session, comprising:

• providing a session control Signaling-plane Anchoring Function (SAF) between a set of first access connections and a remote connection corresponding to a HandOver Remote Function (HORF), wherein:
• each first access connection corresponds to a HandOver Source Function (HOSF) in an HOSF set in a session and is associated with a target media stream;
• the HOSF set comprises at least one HOSF;
• and the HOSF corresponds to at least one first access connection;
• associating, by the SAF, a media stream corresponding to the target media stream with a second access connection between the SAF and each HandOver Destination Function (HODF) in an HODF set after the SAF receives a stream operation request, wherein the HODF set comprises at least one HODF and the HODF corresponds to at least one second access connection;
• and
• performing, by the SAF, a stream operation on the second access connection and processing continuity of the target media stream.
