Abstract
Methods and apparatus are provided for performing a trace session between a first user equipment (UE), and a second UE in a telecommunications network including an IMS network. A trace session initiator activates the trace session with an activation request message, or a Session Initiation Protocol (SIP) INVITE message, including trace settings comprising informational elements describing the trace session. The activation message may be converted into the SIP I NVITE message and sent towards the first and/or the second UE. The SIP INVITE message may include trace settings as extensible mark-up language (XML) informational elements within the body of the SIP INVITE request message and/or as request Uniform Resource Identifier informational elements within the SIP INVITE request message. Network elements in the communications path between the UEs are configured to detect the trace session by detecting the trace settings in the SIP INVITE request message and act accordingly.
