    摘要: A technique for managing an automatically established roaming agreement between two IMS networks (102, 104) is described, wherein one IMS network (102) supports multiple proxy nodes (302, 106) at the network edge towards the other IMS network (104). A method embodiment of the technique is performed in an I-CSCF (302) of the first IMS network (102) and comprises the steps of receiving (316) a registration request of an UE (306) via a second IMS network (104); sending (324) a roaming information request indicating the second IMS network (104) to a HSS (110) associated with the first IMS network (102); receiving (326) from the HSS (110) a roaming information answer indicating information related to the roaming agreement, and forwarding (328), based on the roaming information answer, the registration request to a second I-CSCF (106) of the first IMS network (102) managing the roaming agreement.

    摘要: Techniques for managing a registration of a roaming user terminal (116) in its IMS home network (102) based on a roaming agreement between the visited IMS network (104) and the home IMS network (102) are described. According to one embodiment of the invention, a method for managing user registrations in the first IMS network (102) is provided. The method may be performed in an I-CSCF (106) of the first IMS network and comprises the steps of determining a status change in an automatically established roaming agreement with the second IMS network; and sending, based on the determination result, roaming status update information (204) to an HSS (110) associated with the first IMS network for initiating a registration update of the user.
