    Abstract: In systems and methods of transporting data over an optical transport network, a first client signal and a second client signal are received at a network element of the optical transport network, each of the first client signal and the second client signal comprising a header and a data payload. An optical data unit is assembled comprising the first client signal and the second client signal in sequence, and the optical data unit is transmitted over the optical transport network. The first data payload and the second data payload may not be interleaved, and further, the first header and the second header may not be interleaved. The optical data unit can comprise the first client signal and the second client signal in a time sequence.

    Abstract: Retransmission parameters are determined for a wireless device based on a desired retransmission success rate, that is, a probability that subsequent random access requests transmitted from the wireless device re-initiating a contention-based random access procedure with an access node will reach the access node. The retransmission parameters are determined based on at least a quality of service associated with the wireless device, a distance of the wireless device from the access node, and a cell load of the access node. The retransmission parameters include a retransmission power and a retransmission backoff window size. A product of the power and backoff window is scaled such that it can be equated with a retransmission success rate.

    Abstract: Exemplary embodiments described herein include systems, methods, and nodes for selecting a donor for a relay wireless device. Signal levels corresponding to signals received at a relay wireless device from a plurality of access points are determined. Signal information is received from the plurality of access points, wherein the signal information comprises a group identification for each access point. The signal information for the access points may then be compared to a donor criteria. And the access point corresponding to the greatest signal level that also comprises signal information that meets the donor criteria may be selected as the donor for the relay wireless device.

    Abstract: A method of operating a communication system includes communicating a traffic channel information stream with a wireless device using a first air-interface scheme while communicating control channel information with the wireless device using the first air-interface scheme. The control channel information is communicated with the wireless device using the first air-interface scheme is used to handover the wireless device from the first air-interface scheme to a second air-interface scheme. After the handover of the wireless device from the first air-interface scheme to the second air-interface scheme, the traffic channel information stream is communicated with the wireless device using the second air-interface scheme while still communicating control channel information with the wireless device using the first air-interface scheme.

    Abstract: To determine a cause of a customer experience event (e.g., dropped call or choppy video) passively collected measures from various network layers (e.g., internet, transport, application, etc.) are used to establish user activity across multiple service types (a.k.a., contexts). These contexts are monitored across parallel contexts, services, and/or sockets. The multiple contexts are aggregated for analysis. The multiple contexts can be analyzed to determine a cause of the customer experience event.

    Abstract: A first wireless device is served with an access node. The access node has a first coverage area. A second wireless device is served with a sub-cell access node. The sub-cell access node has a second coverage area that is contained within the access node coverage area. Based on the determination to reduce the load on the sub-cell access node, a handover of a wireless device from the sub-cell access node to the access node is caused by reducing the transmit power used by the sub-cell access node. Based on a comparison of a first signal quality indicator associated with a first sub-cell access node to a second signal quality indicator associated with a second sub-cell access node, a transmit power from the first access node is reduced.
