International Classification:

H04M 7/00

US Classification:

379229, 37922001, 379230

Abstract:

A signaling network node is configured for identifying a received signaling message as belonging to one of a plurality of prescribed originating node groups, based on prescribed message class selection criteria. Each originating node group has at least one originating node and is assigned at least one congestion threshold relative to a message rate (e. g. , messages per unit time or number of bytes per unit time). The signaling network node determines the message rate for each corresponding originating node group; if the message rate for an originating node group exceeds the corresponding at least one congestion threshold, the signaling network node outputs a congestion signaling message to the originating node having sent the signaling message, for reduction of the corresponding message rate.

International Classification:

H04M 7/00

US Classification:

3792211, 379219, 379229, 379230, 37920101, 37911205, 37911501, 37911502, 370352

Abstract:

An originating node is configured for generating a route management signaling message having a signaling link selection (SLS) value that is selected by the originating node based on an affected destination value. The affected destination value, distinct from a destination point code (DPC) that specifies a destination node for the route management signaling message, identifies an affected signaling node that is affected by the route management signaling message. Hence, route management signaling messages related to the affected signaling node are routed along the same signaling path, ensuring that all the related route management signaling messages remain in sequence. Further, different signaling path can be established for respective affected signaling nodes, providing load sharing of route management signaling messages relative to the respective affected signaling nodes.

International Classification:

H04L 12/56

US Classification:

370412, 3703954, 370468, 370474

Abstract:

A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and determining whether one or more samples included in the flow should be suppressed. The method further includes suppressing a selected one or more of the samples if the selected samples are similar to previously received samples and interleaving one or more voice data segments associated with a voice call into outgoing Internet protocol (IP) traffic flows. In more particular embodiments, packets that do not come in from a GSM port on the cell site element are designated as default best effort (BE) traffic.

International Classification:

H04L 12/26

US Classification:

370392

Abstract:

A signaling network node is configured for identifying a received signaling message as corresponding to one of a plurality of prescribed message classes, based on prescribed message class selection criteria. The signaling network node determines an outbound linkset for the received signaling message based on selected message parameters, for example destination point code, input linkset, service indicator values, etc. , where the outbound linkset typically includes at least two links. The signaling network node selects one of the at least two links based on the identified message class.

H04L 12/28

US Classification:

341 87, 370394

Abstract:

A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and inspecting the bits. The method also includes determining whether one or more samples included in the flow should be suppressed. A portion of the bits is converted to 1 bits such that they are designated for later suppression. A selected one or more of the samples are suppressed if the selected samples are designated for suppression.

Abstract:

A method for communicating data is provided that includes receiving a plurality of bits associated with a communications flow and determining whether one or more samples included in the flow should be suppressed. The method also includes suppressing a selected one or more of the samples if the selected samples are similar to previously received samples. In a more particular embodiment, the method also includes positioning unique samples that are included in the flow in a super-frame to be communicated to a next destination. Additionally, the method may include receiving the unique samples and evaluating the unique samples in order to restore a plurality of bits associated with the communications flow.

US Classification:

370230, 37039521, 370231, 370234

Abstract:

An apparatus for communicating data is provided that includes a cell site element associated with a base transceiver station and operable to receive a plurality of packets associated with a communications flow, the packets including a plurality of subrates. The cell site element is further operable to detect a congestion condition via a measurement of a level in a receive jitter buffer. When the congestion condition exists, individual subrates can be dropped from subsequent backhaul packets until congestion subsides. Single timeslots of the flow are systematically added back during a configured time interval such that congestion abatement will back-off gradually. In more particular embodiments, the cell site element can be informed that congestion exists, whereby a congestion level is assigned to a collection of the subrates. In addition, the cell site element prioritizes the subrates and removes individual samples from one or more of the packets.
