if the CS in the first domain is not managing the session history, receiving, by the CF, a second message from the CS in the first domain, the second message specifying an entity managing the session history;
receiving, by the CF, via the CS in the first domain from a CS in a second domain, a third message including access information for the CS in a second domain, which has the session history;
sending, by the CF, a fourth message to the CS in the second domain, which has the session history, based on the access information, the fourth message requesting the session history; and
