摘要： The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.

摘要： A mobile host MH and its home network HN correspond to both the Internet Protocol version 4 (IPv4) and the Internet Protocol version 6 (IPv6). An authentication server (RS) is accommodated in the home network HN. A corresponding host H corresponds to the IPv6 and is accommodated in the IPv6 network. In addition, a plurality of relay servers S1, S2 and S3 corresponding to both the IPv4 and the IPv6 are accommodated in the IPv6 network. The respective S1, S2 and S3 extract an IPv6 packet by decapsulating the IPv4 packet received from the mobile host MH via the IPv4 network, and transfers the relevant IPv6 packet to the corresponding host H via the IPv6 network.

摘要： In a network including equipment noncompliant to the topology management protocol, a message substitution response system executing substitution response to a message discovered or topology search message in lieu of the noncompliant equipment is provided. The substitution response module generation unit 22 generates a substitution response module which responds to Discover message and topology search message in lieu of each of LLTD noncompliant equipment for every LLTD noncompliant equipment. The network simulation module generation unit 23 generates a network simulation module for simulating message transmission on the home network. The substitution response functional unit 24 simulates message transmission between the home network and each of substitution response modules, and message transmission between each of substitution response modules by said network simulation module.

摘要： An administrator 4 (2) registers configuration files of compliant equipment 31 and noncompliant equipment 32 and a configuration script into a management server, and (3) sends the network equipment to a user 33. When the user 33 constructs the local network 3 by connecting the network equipment and turns it on, (4) a configuration request message is transmitted from the compliant equipment 31 to the management server 2. (5) The management server 2 replies with the configuration file of the compliant equipment 31, the configuration file of the noncompliant equipment 32, and the compliant script to the compliant equipment 31 in response to the configuration request. The compliant equipment 31 (6) registers its own configuration file received from the management server 2 into itself, and then (7) configures the configuration file of the noncompliant equipment 32 into the noncompliant equipment by executing the received configuration script.

摘要： A mechanism by which handoff delay can be minimized while not compromising the IMS/MMD security and also protecting the media if required by certain applications is presented. One proactive method includes proactive authentication. Another proactive method includes proactive security association, such as transferring SA keys from old proxy to new proxy, or transferring keys through serving signal entities. Reactive methods include transferring SA keys from old proxy to new proxy, using either push or pull technology. Other reactive methods include transferring keys through serving signal entities using either push or pull technology.
