Abstract: Systems, methods, and software are provided to manage a handover of a mobile station from a source base station to a target base station. In an embodiment, a method comprises monitoring a condition of a first backhaul link between the source base station and an access node, processing the condition of the first backhaul link to determine if the handover should be initiated, and in response to determining that the handover should be initiated, transmitting a handover request to initiate the handover.

Abstract: A method of operating a communication system to communicate with a plurality of wireless devices comprises determining a first shape for a first wireless signal to reach the plurality of wireless devices, transmitting the first wireless signal encoded with a first communication to the plurality of wireless devices, receiving an acknowledgment from a first device of the plurality of wireless devices indicating that the first device received and decoded the first communication, determining a second shape for a second wireless signal to reach a second device of the plurality of wireless devices, and transmitting the second wireless signal encoded with error correction information for the first communication to the second device of the plurality of wireless devices.

Abstract: A transmitter generates error correction data according to an error correction scheme that logically arranges the communication data in a number of rows and a number of columns. The transmitter transmits the communication data and the error correction data. A receiver receives the communication data and the error correction data. The receiver processes the error correction data to correct errors in the communication data. The receiver generates information regarding the errors in the communication data. The transmitter processes the information to alter at the number of rows and/or the number of columns.

Abstract: Systems and methods for transmitting video are provided. The system determines the type of encoded video frames. Each of the video frames is then placed in a network transport packet. A priority level of the network transport packet is set based on the determined type of the video frame. The system can apply error correction coding to video frames of a lower priority level.

Abstract: A method for tracing a communication route through a network coupling a first device with a second device is provided. A first signal is transferred from the first device to the second device to cause a plurality of intermediate devices to report first information concerning the first signal. The first information is processed to identify the intermediate devices as defining the communication route. The intermediate devices are configured so that a second signal, when transferred from the first device toward the second device, causes a subset of the intermediate devices to report second information concerning the second signal. The second signal is transferred from the first device toward the second device. The second information is processed to identify the subset of the intermediate devices as a portion of a sequence of the intermediate devices defining the communication route.

Abstract: A method for characterizing performance of an error correction scheme for digital data transport is provided. A digital data packet stream within an Internet Protocol packet stream is monitored for a first set of packet errors. Errors of the Internet Protocol packet stream are corrected according to the error correction scheme to produce a corrected Internet Protocol packet stream. The digital data packet stream within the corrected Internet Protocol packet stream is monitored for a second set of packet errors. The first and second sets of packet errors are compared to characterize the performance of the error correction scheme.

Abstract: A communication system receives packets transmitted by a user device. The packets implement a named service application to provide a communication service. The system transmits the packets to a packet network and identifies a communication problem. The system transmits information for delivery to the user device indicating that the named service application will be inhibited due to the communication problem and offering an alternative service application to provide the communication service. The system receives an acceptance transmitted by the user device, and in response, transmits the alternative service application for delivery to the user device. The system receives additional packets transmitted by the user device. The additional packets implement the alternative service application to provide the communication service. The system transmits the additional packets to the packet network.

Abstract: A method for transferring and correcting communication data is provided. The communication data include data frames, wherein each data frame includes data packets logically arranged in a number of rows and columns. Each data frame also includes error correction packets associated with the data packets. The error correction packets are generated according to an error correction scheme based on the number of rows and columns. The data frames are transmitted and received. The error correction packets are processed to correct errors in the data packets. Information regarding the errors in the data packets is generated. This information is processed to alter at least one of the number of rows and the number of columns.

Abstract: A control system for a communication network stores a plurality of fault recovery plans that are respectively associated with a plurality of links. The control system processes a first control signal from the communication network indicating that one of the links has a fault, and in response, identifies one of the fault recovery plans that is associated with the one link having the fault and implements the one fault recovery plan. The control system receives a second control signal from the communication network indicating network information, and in response, recalculates the fault recovery plans. The recalculated fault recovery plans implement link-based fault recovery, sub-path based fault recovery, and path-based fault recovery. The recalculated fault recovery plans group links constituents into groups by QoS requirements and assign the groups to back-up routes based on the QoS requirements and the performance of the back-up routes.
