Obtaining signaling information in a packet switched network

摘要

A first end node obtains trace information in a packet switched network. The first end node sends a request message for setting up a test call towards a second end node. The request message includes a first request for collecting trace information. The second end node sends a first response message, to the first end node, that includes a trace request and trace information. The first response message is routed between the second and first end nodes via at least a first intermediate node that adds additional trace information relating to the first intermediate node to the trace information of the first response message. The first end node receives the first response message, which includes the additional trace information added by the first intermediate node.

1. A method for obtaining trace information in a packet switched network, the method comprising:
a first end node sending a request message for setting up a test call towards a second end node in the packet switched network, the request message comprising a first request for collecting trace information; the second end node sending a first response message to the first end node in response to receipt of the request message, the first response message comprising a trace request and trace information; routing the first response message between the second end node and the first end node via at least a first intermediate node in the packet switched network, the first intermediate node adding additional trace information relating to the first intermediate node to the trace information of the first response message; the first end node receiving the first response message, the first response message comprising the additional trace information added by the first intermediate node.
