Embodiment Construction

[0030] discussed below Figure 4 to Figure 8 And the principles used to describe the invention in this patent document are for illustration only and should not be construed as limiting the scope of the invention in any way. Those skilled in the art will understand that the principles of the invention may be implemented in any suitably arranged communication network using a bidirectional signaling protocol stack.

[0031] As mentioned above, a problem with current solutions is that they only allow limited or cost-inefficient reconstruction of SIP signaling sequences that occur during a signaling session. The improvement of the invention focusing on suitable utilization in the new SIP (Session Initiation Protocol) header enables a complete reconstruction of the signaling sequence and provides enhanced fault localization and fault diagnosis capabilities. This scheme will now be described in detail.

[0032] SIP signaling sequences are partly performed in the IMS (IP Multimedia ...

Abstract

A method and apparatus enabling performance monitoring in packet-switched IP networks such as those configured according to an IP multimedia subsystem, IMS, architecture. Performance is monitored by reconstructing selected control signaling sequences. The control signaling sequences, which are typically executed according a signaling protocol such as the Session Initiation Protocol, SIP, are reconstructed by parsing the contents of monitoring request headers configured, modified, and attached to control messages according to the present invention. The header includes at least an IMS monitoring ID field (510) for identifying the signaling sequence to be reconstructed, a processing node ID field (520) for representing the entities processing the messages, and a requester ID field (530) for identifying a requesting entity. It may also specify a monitoring level (540) indicative of the monitoring tasks required. The monitoring may be requested by an IMS node, or by an entity outside the IMS.

Description

technical field [0001] The present invention relates generally to packet-switched network communications, and more particularly to the reconfiguration of signaling sequences through these networks, e.g. for SIP (Session Initiation Protocol) control signaling sequences in IMS (IP Multimedia Subsystem) networks A way to monitor performance and locate faults. Background technique [0002] In recent years, the technologies that permit large-scale mobile network communications have improved significantly. Users at mobile sites can now not only make standard phone calls over the cellular network, but also have access to a variety of voice and data services including e-mail applications and audio, video and multimedia presentations. Many of these services are delivered using packet-switched IP (Internet Protocol) networks connected through gateways to cellular networks. Other types of mobile devices, such as laptops, also access these services via eg WLAN (Wireless Local Area Net...
