20080239950 | Telecommunications Method and System involving Active Nodes Having Full Receive State and Isolated Receive State from Non-Allocated Traffic - A telecommunications system. The system includes a communications network. The system includes N nodes, where N is an integer greater than or equal to 2, which run a same or different applications and process a same or different ranges of application level traffic, and which communicate with each other through the network using signaling by SIGTRAN protocols. Each of the N nodes has a full receive state where a node receives any type of traffic from the other nodes and an isolated receive state where the node only receives allocated traffic from the other nodes. The node sends traffic to the other nodes whether the node is in the full receive state or the isolated receive state. A method for communicating. | 10-02-2008 |
20090313350 | METHOD FOR OPTIMISING THE DISTRIBUTION OF A SERVICE FROM A SOURCE TO A PLURALITY OF CLIENTS IN A NETWORK - This method for determining locations of service instances for optimising distribution of a service in a network, from a source to a plurality of clients each having predetermined requirements, wherein the network can be modelled by means of a graph, comprises steps of: placing a service instance in each leaf in the graph; and, starting from the leaves, for each service instance: checking whether the service instance when placed in a vertex on the next higher level can fulfil the requirements of all clients to be served by said service instance; and moving or not the service instance one level higher, depending on the result of the checking step. | 12-17-2009 |
20100161325 | Individual Codec Pathway Impairment Indicator for use in a Communication System - A system and method are described for controlling the setup of a connection in a communication network that includes a set of nodes, such as Mobile Switching Centers (MSCs) and Media Gateways (MGWs). In one example, a speech connection is established between MGWs subject to the control of the MSCs, which can selectively activate or deactivate codecs along the connection. The codecs are selected from a list of supported codecs, each potentially affecting connection quality by differing amounts. A Total Accumulated Impairment (TAI) element is forwarded between the MSCs and step by step updated by these MSCs that includes individual partially accumulated impairment values corresponding to each of the supported codec candidates. Each individual indicator value provides information representative of the expected accumulated impairment along a candidate connection path leading up to, and including, the corresponding codec. By providing information pertaining to the expected accumulated impairment along each candidate connection path, the MSCs can determine an optimum sequence of codecs so as to minimize the overall connection impairment. | 06-24-2010 |
20110087800 | Network Node and Method of Routing Messages in an IP-Based Signaling Network - A method of routing messages in an IP-based signaling network is provided. Further, a network node ( | 04-14-2011 |
20110110221 | Signaling Gateway for Routing Signaling Messages - A method of operating a signaling gateway for routing signaling messages between a SS7 network and an IP-based network is provided. The signaling gateway has a signaling point code allocated as a network address. Further, a signaling gateway for routing signaling messages between a SS7 network and an IP-based network is provided. The signaling gateway comprises an interface towards the SS7 network and an interface towards the IP-based network. The signaling gateway comprises a processing unit which may implement a SS7 protocol stack and an IP protocol stack. The processing unit may be configured to translate a message delivered to an upper protocol layer of the SS7 protocol stack to a corresponding message conforming to a user adaptation protocol of the IP protocol stack. | 05-12-2011 |
20110264807 | Method of Operating a Signalling Gateway and an Application Server, and Signalling Gateway and Application Server - A method of operating a signalling gateway in a decoupled mode of operation for routing signalling messages between an SS7 and an IP-based network is provided. Further, the invention relates to a method of processing a connection oriented signalling message at an application server process, wherein the message is exchanged via a signalling gateway between an SS7 network node and the application server process. The application server process serves at least one application server in an IP-based network. The invention further provides a signalling gateway for routing signalling messages between an SS7 network and an IP-based network and an application server comprising an application server process for processing signalling messages, in particular connection oriented messages. | 10-27-2011 |
20130223433 | Reducing Broadcast of SS7 Network Management Messages by SIGTRAN Relay Node - The application relates to the transport of SS7 signaling over an Internet Protocol based network and in particular to the routing of SS7 Signaling Network Management SSNM Messages such as Destination Unavailable DUNA and Signalling Congestion SCON by a SIGTRAN relay node. The SSNM messages are checked against a so-called “validation rule”, which either specifies a list of allowed affected point codes or a threshold rate of SSNM messages with the same affected point code. If the SSNM message is “valid” it is sent to a so-called “broadcast domain” which comprise nodes such as signaling endpoints or component of one or more application servers. | 08-29-2013 |
20140153563 | Network Node and Method of Routing Messages in an IP-Based Signaling Network - A method of routing messages in an IP-based signaling network is provided. Further, a network node for performing such a routing of messages in an IP-based signaling network is provided. The network node comprises at least two interfaces and a processing unit configured to route an incoming message received at a first of the at least two interfaces to a second interface of the at least two interfaces. Further, a relay network comprising plural of such network nodes as relay nodes is provided. | 06-05-2014 |
