CHARGING ID CORRELATION IN AN IMS NETWORK

摘要

In a method of correlating information relating to message in a SIP session, a first SIP message that includes a first IMS Charging Identifier, ICID, is received. The first SIP message is retargeted by generating a second SIP message that includes a second ICID. A reference to the first ICID is inserted into the second SIP message. Information relating to the first SIP message is correlated with information relating to the second SIP message based on the first ICID and the reference to the first ICID in the second SIP message.
