International Classification:

H04W 4/00

US Classification:

370331, 370332

Abstract:

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.

International Classification:

H04W 4/00

US Classification:

370328, 370338, 455434

Abstract:

The present application describes, inter alia, novel techniques to perform pre-evaluations of multiple Wi-Fi Access Points (AP) and Access Networks (AN). A pre-evaluation determines whether or not an AP is connected to the Internet and measures the path performance that the AN, via that particular AP, can offer between the mobile device and a pre-specified Internet host. In addition, the invention also discloses methods to determine whether the AN requires a user to actively authenticate themselves through a redirect log-on page.

Abstract:

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.

International Classification:

H04L 9/00

US Classification:

726014000

Abstract:

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.

US Classification:

715736, 709224

Abstract:

This present application relates to, among other things, novel techniques to evaluate and qualify multiple networking options. A device contains multiple network connectivity options, including but not limited to various wireless and wired technologies such as Wi-Fi, 3G, WiMAX, LTE, Ethernet, Bluetooth, UWB, WHDMI, etc. Each connectivity option can be evaluation and pre-qualified prior to the user selecting that mode of communication. This evaluation process takes into account both lower-layer information such as signal strength, bit error rates, SNR, interference, etc. but also network-layer information such as IP connectivity, and end-to-end path performance.
