TURN RELAY SERVICE REUSE FOR NAT TRAVERSAL DURING MEDIA SESSION RESUMPTION

摘要

A call media session restoration method comprising detecting a network reconnection triggering event that disconnects a media session for a client and a relay connection on a network device for the media session, sending a relay address allocation request to the network device, wherein the relay address allocation request comprises a session update attribute that identifies the relay connection, receiving a user authentication request message from the network device, authenticating the relay address allocation request with the network device, wherein the relay address allocation request is authenticated in accordance with the user authentication request message, and wherein authenticating the relay address allocation request comprises resending the session update attribute, and performing a connectivity check between the client and a peer via the relay connection, wherein performing the connectivity check restores the media session and the relay connection and reuses the relay address for the relay connection.
