The data are in a Session Initiation Protocol (SIP) MESSAGE in accordance with the SIP.

In another embodiment, the home network holds account details relating to the use of the foreign network by the mobile user. In response to a SIP MESSAGE from the foreign server identifying the mobile user and the service or services requested by the mobile user, the home server sends to the foreign server a SIP MESSAGE including data indicating permitted use of the foreign network by the mobile user. The foreign server uses the SIP message to control access by the mobile user to a specific service or a number of identified services in the foreign network.
