Abstract: Disclosed are a system and a method for implementing an XDM forward function described in [XDM2_RD] and [XDM2 AD]. The method includes the steps of: transmitting, by the XDM forward requesting user a forward request message for forwarding a desired XML document to the XDMS; receiving, by the XDMS the forward request message, determining if the XDM forward requesting user has been granted a forward authority for a forward-requested target XML document forwarding the requested XML document to the XDM forward receiving user when the XDM forward requesting user has been granted an authority to forward the target XML document, performing receiver authorization for determining if an XDM forward receiving user can accept the forwarded XML document, and confirming that the XDM forward receiving user owns the forwarded XML document and storing the possessed XML document in a user directory when the receiver authorization has been successfully performed.

Abstract: A method and system for registration with a broadcast server is provided. A request from a smartcard terminal for registration is received and the smartcard terminal is authenticated based on the request. Further, A specific key material, Ks_NAF, is generated in response to the request. At least one of registering the smartcard terminal with the Internet Protocol (IP) multimedia subsystem (IMS) server and with the broadcast server simultaneously, and registering the smartcard terminal with the IMS server and subsequently with the broadcast server through the IMS server, is performed. At least one of notifying the IMS server of status of the registration by the broadcast server, and notifying the broadcast server of the status of the registration by the IMS server, is performed.

Abstract: A method for connection roaming a Mobile Node (MN) to a Network GateWay (NGW) for providing secure data path using Internet Protocol (IP) security procedure. Also Mobile IP (MIP) is required for providing mobility to the user, when the MN moves from one sub-network to another. However, when the Home Address of the network is not known, a cyclic interdependency is observed between the IP Security (Ipsec) procedures and IP procedures. If the home address of the MN is not known initially during the procedure, IPsec Security Associations (SA's) are formed between the MN and NGW such that only IP packets are passed through. After the IP Registration is completed, the Home Address of the MN is known from the MIP registration Reply. MN now forms a data path tunnel with the NGW by exchanging Create_Child_SA messages.

Abstract: Method and system for facilitating tunnel management in the 3G-WLAN interworking systems providing dynamic configuration of maximum number of IP Security Protocol (IPsec) tunnels allowed per Internet Key Exchange (IKE) Security Association (SA) at the Packet Data Gateway (PDG) during the initial tunnel establishment procedure. Authentication Authorization and Accounting (AAA) server is notified of the new IPsec tunnel established between the user equipment (UE) and the PDG.
