摘要:
The invention concerns a method of providing a Push-to-Talk (=PTT) service within one or more telecommunication networks (1, 2, 3, 4) by means of a gateway-server (5) which sets up a virtual connection per PTT connection. The virtual connection provides information about the participating terminals (10, 20, 30, 40) of the PTT connection, the service type to reach each terminal (10, 20, 30, 40), and the connection status of each terminal (10, 20, 30, 40). Thus, the gateway-server (5) is capable of providing the PTT service within and/or across different telecommunication networks comprising radio access telecommunication networks (1), fixed wire-line telecommunication networks (2), circuit-switched telecommunication networks (3), and packet-switched telecommunication networks (4).

The application relates to a method of handling a group communication in a communications network, comprising the steps of agreeing and arranging participating clients of a group; establishing a communication session for directed exchanging of streamed media between the participating clients, coordinating communication resources, especially the direction of exchanging of streamed media, i.e. re-assigning a communication resource to a client when this clients has requested this communication resource, where the clients are symmetrically organized as peers in the communication network, i.e. there is no distinguished (centralized) client but a distributed system of peers (P1, P2, P3), where a peer to peer network among the participating clients is established for coordinating the direction of exchanging of streamed media by electing at least one participating peer (P1, P2, P3) of said group of participating peers (P1, P2, P3) as a source peer; and piping the streamed media originated by the at least one participating peer (P1, P2, P3) to the participating peers via the peer to peer network, and coordinating the mutual exclusive communication resources by initiating an election by a request (1′), and resolving the concurrent request (2′, 4′, 7′, 6′) fair and alive by a distributed election algorithm between the peers using the peer to peer network. The invention also relates to a computer software product, a network client, and a communication system therefor.
摘要:
The invention concerns a method of remote metering of energy consumed and/or inputted by a plurality of energy consuming and/or inputting units (4) of a power grid (5) as well as a device for remote metering. Each unit (4) comprises at least one meter (2) and/or a meter box (1) connected with one or more meters (2) and the meter boxes (1) and/or the meters (2) are connected with at least one backend platform (3) via a communication network. At least two of the group of meter boxes (1), meters (2) and backend platforms (3) communicate with each other by means of a generic bi-directional resource management protocol on top of an IP protocol stack via the communication network and thereby encode and decode data transferred via the resource management protocol according to a predefined extensible specification comprising a functional group for meter information and control.
摘要:
The invention concerns a method for adapting modalities of a dialog between a client (42 to 44) and a server, an interaction server (2) and a computer program product. A set of dialog modality capabilities and/or dialog modality requirements are provided to an interaction server (2). The interaction server (2) mediates between the dialog modality capabilities and/or dialog modality requirements of the client (44) and the server. Further, it selects the dialog modalities of said dialog based on said mediation.
摘要:
A low-cost implementation of a voice message system is indicated. To that end, a digital signal processor (DSP) and a second memory (ROM) with program modules for executing the functions of "automatic operator" and/or "mailbox" are integrated in a digital telephone (TE4). In addition, the digital telephone (TE4) is able to execute an "individual messages" function, whereby a message intended only for another telephone (TEA) is transmitted to this other telephone (TEA) by means of the digital telephone (TE4).
摘要:
An exemplary method and apparatus are provided for operating a power grid that has decentralized control elements. The decentralized control elements are adapted to interact with each other, in particular by communication. At least a part of the power grid, a control element or the interaction between control elements, in particular the communication between control elements, is monitored. When a problem in at least a part of the power grid, the control element or the interaction between control elements, in particular a communication breakdown, is detected, a control element affected by the problem is triggered to work autonomously.
摘要:
A method for transferring energy between first and second units with first and second meters and subscriptions to first and second backend platforms, as well as a first unit for supporting such energy transfer, where the backend platforms execute an authentication procedure and a switch is unbarred by the first control box upon successful execution of the authentication procedure. A second control box sends an amount of the transferred energy measured by the second meter to the first control box energy consumption data is sent to the backend platforms, and a consumption clearing procedure is executed between the first and the second units at the backend platforms by means of the received energy consumption data.
摘要:
The invention concerns a method of visualizing consumption information, the method comprising the steps of presenting (103) the consumption information to a consumer and presenting (104) to the consumer a benchmark for assessing the consumption information, wherein the method further comprises the steps of, prior to presenting (104) the benchmark, determining (101) a peer group of consumers based on a characteristic of the consumer and determining (102) the benchmark based on the peer group. The invention further concerns a corresponding device, storage means, and software program therefor.
