摘要： The steps and the data amount are reduced by using a PPP non-standard message to shorten a time needed for call setting, and even when a terminal or PDSN is not adapted to the non-standard message, a call setting procedure can be continued according to a PPP standard procedure. The procedure contains the steps of: establishing a wireless link between MS and PDSN, transmitting PPP standard LCP Cfg-Request from PDSN to MS, transmitting PPP non-standard AltPPP Cfg-Request from PDSN to MS, responding to AltPPP Cfg-Request and returning non-standard AltPPP Cfg-Response if MS is adapted to the non-standard message while responding to LCP Cfg-Request and returning standard LCP Cfg-Response if MS is not adapted to the non-standard message, and authenticating MS on the basis of the standard or non-standard Cfg-Response by PDSN.

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 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.

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. Methods for mitigating delay during SA re-association and mitigating the IPSec tunnel overhead for signaling and media at the Mobile Node are given. In one embodiment, SA keys can be transferred from the old P-CSCF to new P-CSCF, enabling the establishment of SAs before Mobile Node physically moves to the new subnet in a network. Proactive handover is used. In another embodiment, SA keys are transferred from S-CSCF to new P-CSCF. In this case, the SA keys are transferred to the new P-CSCF by S-CSCF through a context transfer mechanism well in advance so that SAs may be established before Mobile Node physically moves to new subnet. In another embodiment, methods for mitigating IPSec tunnel overhead are presented.

摘要： An overlay service network and method for delivering a multimedia service. The overlay service network comprises a user interface for subscribers to request an available service as a requested service, a register server for registering and storing a database of available services, a plurality of service nodes for executing at least one available service and a controller for receiving a request for an available service, searching the register server for the requested service, selecting one or more of the plurality of service nodes to execute the requested service and establishing a chaining sequence between a node requesting the service, the one or more selected execution nodes and a destination node to execute the requested service.
