How has Japan become a major economic power, a world leader in the automotive and electronics industries? What is the secret of their success? The consensus has been that, though the Japanese are not particularly innovative, they are exceptionally skilful at imitation, at improving products that already exist. But now two leading Japanese business experts, Ikujiro Nonaka and Hiro Takeuchi, turn this conventional wisdom on its head: Japanese firms are successful, they contend, precisely because they are innovative, because they create new knowledge and use it to produce successful products and technologies. Examining case studies drawn from such firms as Honda, Canon, Matsushita, NEC, 3M, GE, and the U.S. Marines, this book reveals how Japanese companies translate tacit to explicit knowledge and use it to produce new processes, products, and services.

The knowledge-creating company : how Japanese companies create the dynamics of innovation

A preferred contact group centric interface for a communication device can be used to facilitate communications by a user. The user interface can be arranged to activate from a user's “home page” on the display, from an idle screen that is accessed after a timeout period expires, or any other appropriate mechanism that activates the preferred contact group centric experience. A user selects the preferred contact group from among an array of the user's contacts. Once the contact group is configured, a minimal number of navigation/selection features is necessary to activate any number of communication modes available to the contacts. The contact group is configured such that simple and quick navigation between the contact members is achieved. The contact group can be presented in 2D and 3D arrangements, in any number of list or geometric configurations. A pricing plan can optionally be tied to each member of the contact group.

A user interface presents a plurality of items configured as a stack in a display of a device. The stack is scrollable in a direction oblique to a plane of the display for successively viewing the items in the stack. Some implementations provide multiple stacks of items laterally navigable into a viewable area of the display.

User Interface with Z-axis Interaction and Multiple Stacks

Communications between social networks are enabled via authentication that provides single-sign-on (SSO) authentication of users such as individual users or social networks or social network services that desire access to network resources on a particular social network. The particular network requests authentication of the requesting user(s), and based on an authentication result the particular network provides or denies access to the resources. A social network services database maintains a listing of resources of different social networks, that a user can search to determine where to find resources on other networks. The user can then query the social networks hosting those resources or their social network services for access, and the networks or services can authenticate the user before granting access according to any conditions that the hosting social networks or social network services may choose to apply.

Federation and interoperability between social networks

A communication system and server includes a first memory for storing terminal information of a first terminal and a second terminal, a second memory for storing outgoing call history information of at least either the first terminal or the second terminal, a third memory for storing incoming call history information of at least either the first terminal or the second terminal; and a processing unit for reading out the information from the first memory to control at least either information of the second memory or the third memory in accordance with information contained in a notification from the communication device when setting the connection between at least either the first terminal or the second terminal and the communication device, therefore, two parties to be communicated with each other specify a connection terminal of a call source.

This paper presents a realization of a multi-service P2P overlay architecture that allows for establishing SIP multimedia sessions between mobile community members with little or no need for centralized servers of any kind. The overlay architecture forms a cost efficient platform for providing innovative mobile services. As an example, this paper presents an implementation of a mobile P2PSIP VoIP service. The implementation allows a mobile phone user make voice calls using resources of the P2P overlay. The mobile phone user may freely use standard call manager and contact list in a mobile phone. The paper also presents a method for locating relay servers that are used in NAT traversal.

Mobile P2PSIP - Peer-to-Peer SIP Communication in Mobile Communities

The invention presents an architecture of a distributed communication system that combines strengths of Distributed Hash Table (DHT) algorithms and social networks. The system forms a cost efficient platform for providing innovative mobile services. Possible implementations of the proposed system in the IP Multimedia Subsystem and as a standalone SIP based system are presented. The architecture may also be deployed in other systems. Further, a content sharing inside community service is provided.

Method, System, and Devices for Network Sharing or Searching Of Resources

The invention relates to a method for the routing of multimedia communication related signaling in a communication system (200). In the method a signaling message is received to a first network node (224). The signaling message provides an identity associated with a user. A hash key is computed from the identity. The hash key is matched to a number of key ranges, each key range being associated with a network node. A second network node (226) is determined by detecting that said hash key belongs to the key range of the second network node (226). A signaling message is provided (223) to the second network node (226). Subscriber data associated with the identity is obtained in the second network node (226). The signaling message is processed in the second network node (226) based on information in the subscriber data.

An apparatus for providing data management in a P2P network, may include a processor. The processor may be configured to communicate, from an originating node (80), information indicative of a user entry update (100,102) to a destination node (80) via at least one intermediate node (82), receive a response (104,106) to the communicated information via the at least one intermediate node, the response including contact information of the destination node, and establish a secure communication channel (110) directly between the originating node and the destination node using the contact information of the destination node.

A node and method are provided that create a finger table at the node, subscribe to changes in a network address of at least one other node included in the finger table, receive at least one notification including an identifier and a network address of the at least one other node, and update the finger table with a new network address of the at least one other node received in the at least one notification. The node and method also create a reverse finger table at a node, receive subscriptions to changes in a network address of the node from another node, store the network address of the other node in the reverse finger table, and when the network address of the node changes, send a notification of a new network address from the node to the other node in the reverse finger table.
