A method of employing an encoding scheme for media independent handover, comprising: having at least some data type carry only required information to determine the end of data without a length value.

Data type encoding for media independent handover

According to one embodiment, an electronic apparatus includes a data receiver, processing circuitry and an operation information receiver. The data receiver receives first data for displaying an image. The processing circuitry displays, using the first data, the image on a screen of a display. The operation information receiver receives operation information indicating that one of a plurality of buttons provided at a remote control is pressed. The processing circuitry displays, based on the operation information, an enlarged image of a first area of a plurality of divided areas of the image on the screen.

Electronic apparatus and display control method

Provided are a communication device and a communication system capable of specifying a failure part in a network in which a time server and a communication path are made redundant. A communication device acquires time-related information from a plurality of time servers over a plurality of networks and compares the information to specify the failure part in the time servers or in the networks. A remote apparatus acquires time-related information from the communication device over the plurality of networks and compares the information to determine the failure of the communication device.

Communication device and communication system with failure detection capabilities

In some of the preferred embodiments, a method for network discovery of a mobile device to use at least one of a plurality of access networks within an IP network includes: obtaining specified network information in the vicinity of a given location based on a set of criteria when a mobile is connected to the IP network from any location.

Network discovery mechanisms

Systems and methods are described for secure and seamless roaming between internal and external networks. Double and triple tunnels may be used to connect a mobile node to a correspondent host. A mobile node may include the ability to connect to two networks simultaneously to enable seamless roaming between networks.

Secure and seamless WAN-LAN roaming

A solution framework is employed that includes defining of a mechanism to run multiple queries in a single message exchange, along with a priority on a per-query basis. In some embodiments, a system for facilitating handover of a mobile device across heterogeneous access networks by ensuring response to queries transmitted by the mobile device includes: a) a mobile device having a plurality of wireless network interfaces for communicating over a plurality of heterogeneous access networks, having a media independent handover (MIH) entity to facilitate handovers between the heterogeneous networks, and configured to transmit queries related to handover operation between the heterogeneous access networks to MIH entities within said heterogeneous access networks; and b) said media independent handover entity of said mobile device being configured to transmit multiple queries in a single message exchange to an MIH entity in an access network with prioritization among said multiple queries.

Prioritized query

According to one embodiment, an information processor includes a display module and an operation module. The display module displays a plurality of display objects each at a predetermined display position. The display objects are selected in advance by a user from a plurality of objects and includes authentication objects. The operation module is used for operation to select the authentication objects in a predetermined order upon user authentication.

Information processor, information processing method, and computer program product

According to one embodiment, an account aggregation system includes an information processing apparatus and an account aggregation server. The information processing apparatus includes a database, an automatic sign-on process module and an encryption key processing module. The automatic sign-on process module is configured to provide authentication data the service providing servers have requested for, by using the authentication data stored in the database. The encryption key processing module is configured to register, for the account aggregation server, an encryption key for encrypting authentication data to be stored in the database or for decrypting the authentication data stored in the database, to acquire the encryption key from the account aggregation server when a process is performed by using the encryption key, and to erase the encryption key after the process is performed. The account aggregation server includes an encryption key management module which is configured to manage the encryption key.

This document describes a proactive mechanism to provide fast-handover involving PMIPv6. In particular, it describes how one can achieve fast handoff for PMIPv6 using Media-independent Pre-Authentication (MPA) technique. It discusses the need for a fast-handoff for PMIPv6 environment. It then describes how MPA techniques could be used during different steps involving both intra-domain and inter-domain handoff for PMIPv6. MPA-based fast-handover takes advantage of the pre-authentication mechanism so that the mobile can perform the access authentication while in the previous local mobility (PMA) domain and thus would be able to complete many of the handoff related operations while still in the previous network.

Media independent pre-authentication supporting fast-handoff in proxy MIPv6 environment

This application describes, among other things, a framework of Media-independent Pre-Authentication (MPA), a new handover optimization mechanism that has a potential to address issues on existing mobility management protocols and mobility optimization mechanisms. MPA is a mobile-assisted, secure handover optimization scheme that works over any link-layer and with any mobility management protocol. This application also shows, among other things, an initial implementation of MPA in our testbed and some performance results to show how existing protocols could be leveraged to realize the functionalities of MPA.

Framework of media-independent pre-authentication

In a wireless terminal having a wireless transceiver and a wireless receiver which operates with lower power than the wireless transceiver, when the wireless receiver receives, from a base station, a notification message notifying that data addressed to the terminal is existent, the wireless transceiver is turned on to acquire the data.

Wireless terminal, base station, wireless communication system, and wireless communication method

The present invention relates to the use of buffering packets for the mobile node at an access router or network node near the edge of the network that the mobile is moving away from or towards. The buffered packets are then forwarded to the mobile node once the handoff process is completed. This invention also relates to the use of buffering packets originating from the mobile node during the handoff process. The buffered packets are then forwarded to their intended destinations once the handoff process is completed. The buffering system is used in conjunction with existing mobility protocols, access protocols, or as an independent network or link layer mechanism.
