Abstract:
1. A method for enabling signaling sequence reconstruction in an IMS (IP (Internet protocol) multimedia subsystem), the method comprising: receiving a signaling message in a first IMS node, the signaling message forming a part of the signaling sequence; attaching a P-Monitoring-Request header to the signaling message, wherein the P-Monitoring-Request header includes an IMS monitoring ID field for values identifying the signaling sequence to be reconstructed, a processing node ID field for values representing one or more entities processing the signaling messages, and a requester ID field for values identifying a requesting entity; and transmitting the signaling message including the P-Monitoring-Request header to a second IMS node, wherein the first IMS node and the second IMS node are participating in a first signaling dialog.
