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： 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： A data communication method and apparatus for a mobile network. A destination foreign agent (FA2) recognizes a MAC address of an MN. The FA2 registers the MAC address of the MN in a handoff request message (FHReq), and the FA2 feeds the FHReq onto a transfer network. Each of foreign agents (FAs) receives the FHReq, registers an IP address corresponding to the MAC address in the FHReq when the MAC address is registered in a binding list of the FAs themselves, and feeds the IP address onto the transfer network. The FA2 receives the FHReq, and temporarily registers the MAC address and the IP address in the binding list of the FA2 itself. The FA2 transfers data sent from a homw agent (HA) to the MN, based on the information which has been temporarily registered.

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： 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.
摘要翻译：通过使用PPP非标准消息缩短呼叫设置所需的时间，减少步骤和数据量，即使终端或PDSN不适合于非标准消息，也可以按照到PPP标准程序。该过程包括以下步骤：在MS和PDSN之间建立无线链路，从PDSN向MS发送PPP标准LCP Cfg请求，从PDSN向MS发送PPP非标准AltPPP Cfg请求，响应AltPPP Cfg请求并返回如果MS适应于非标准消息而在响应LCP Cfg请求时返回非标准AltPPP Cfg响应，并且如果MS不适应于非标准消息则返回标准LCP Cfg响应，并且基于 PDSN的标准或非标准Cfg-Response。

摘要： The present invention provides a network operations management method and apparatus which realizes efficient power-saving by enabling virtual servers to move between physical servers beyond network segments. A reallocation design unit 13 designs reallocation of virtual servers to physical servers so that necessary resource amounts are assigned to all virtual servers. When virtual servers VS need to move between physical servers PS beyond network segments NS for the designed reallocation, a grouping unit 14 changes a network segment NS to which physical servers PS are connected by changing the configuration of a router and switches. A reallocation unit 15 realizes efficient power-saving by reallocating the virtual servers to the physical servers based on the design made by the reallocation design unit 13.
