摘要:
A method and message server (204) for routing a speech message, received (2:1) from a user equipment (200) of a sending user, to at least one recipient (208, 210) in a communication network. After obtaining (2:2) a text version created by speech recognition (206) of the received speech message, the at least one recipient is identified (2:3) by the message server based on the obtained text version, and the speech message is then routed (2:5) to the identified at least one recipient.

摘要:
A node for use within an overlay network, such as a Distributed Hash Table based overlay network, and which is configured to route packets across the overlay network. The node comprises means for making a routing decision based upon a knowledge of the power consumption levels and/or power availability of a set of peer nodes in the overlay network.
摘要:
A method of maintaining routing tables at nodes of an overlay network, where a routing table of a given node contains, for each of a set of neighbouring successor and predecessor nodes, a mapping between an overlay network address of the node and a physical locator of the node. The method comprises, upon or immediately prior to departure of a node from the overlay network, sending a Leave request from the departing node (or one of the neighbouring nodes of the departing node aware of the departure) to each neighbouring node (or each other neighbouring node of the departing node), indicating the departure and containing one or more mappings for nodes not contained within the routing table of the recipient node. Each neighbouring node (or each other neighbouring node) receives the Leave request and uses said mapping(s) to update its routing table.

A system, node and method for location aware mass information distribution to peers. The method includes overlaying a distributed hash table (DHT) network over an existing physical communication network to which the peers are connected, wherein the DHT network is a peer to peer (P2P) network; providing at least one application layer multicast (ALM) protocol over the overlayed DHT network to form an ALM tree topology for the peers, wherein the ALM tree topology is based on location information of the peers; using the ALM tree topology for establishing logical connections within a group, between a leader of the group and peers of the group; and using the overlayed DHT network for establishing connections, between the leader and the peers, to be followed by a message to be distributed to the peers.
摘要:
An overlay network, node and method for adaptive service discovery. The method uses an adaptive service discovery in the overlay network for finding a peer that provides a desired service; generates a tree structure for current peers that provide the desired service; assign the current peers that provide the desired service to different levels of the tree structure; estimate, when a peer intends to register for the desired service with the adaptive service discovery, a number S of actual peers that provide the desired service; and calculates, based on the estimated number of actual peers providing the desired service, an optimal starting level for the peer to register for the desired service.

Methods and nodes for enabling and producing input generated by speech of a user, to an application. When the application has been activated (2:1), an application node (200) detects (2:2) a current context of the user and selects (2:3), from a set of predefined contexts (204a), a predefined context that matches the detected current context. The application node (200) then provides (2:4) keywords associated with the selected predefined context to a speech recognition node (202). When receiving (2:5) speech from the user, the speech recognition node (202) is able to recognize (2:6) any of the keyword in the speech. The recognized keyword is then used (2:7) as input to the application.
