Abstract
A method of providing location-related charging information to a charging system associated with an IP Multimedia Subsystem, IMS, network, where the location-related charging information relates to a session or session initiation or an event involving at least two users. The method comprises, at a Charging Trigger Function, CTF, within the IMS network, receiving a Session Initiation Protocol, SIP, message from each of said users, each message containing a SIP header identifying a location of the sending user. Location information of each user is added to a charging message sent from the CTF to said charging system, location information being, or being derived from, the content of the SIP header received from the user or being derived from that SIP header.
