Abstract:
Unified Directory Service (UDS) architecture configured for serving an IP mobility communications architecture, the UDS comprising:a) a Home Control and Data Manager (HCDM) connected to a Network, Service Function (NSF) bus, the HMM comprising: an Access Network Interface (ANI) configured for enabling the MN to discover and distinguish an IPM Network to a sub-network level, and for replying to a discovery request from an MN, wherein the IPM network is one of a Local Service Function (LSF) or a Network Service Function (NSF), and wherein the discovery request comprises at least one of an SMM IP address, an SMM NAI, support for available security protocols, and support for local HMM; a Home Mobility Manager (HMM) configured for receiving an IP Address allocated by a DHCP, assigning the allocated IP address to the MN, authenticating the user (AAA), and updating the UDS with a user's mobility related information; and an IP Mobility (IPM) Tunnel Service (ITS) for providing tunneling and de-tunneling; b) a UDS Function connectable to the NSF bus for storing static and dynamic information about a user and making the information available to any application that interfaces with the UDS; c) at least one database connected to the UDS Function via the NSF bus, the database being configured for storing an Internet Protocol Mobility (IPM) user profile comprising at least the COA of the devices used by the user, the type of devices used by the user, the status of the devices at any time, the LSF information that any device is connected to, the user's preference between the devices registered at any time.
