Abstract: A system and method for propagating fault information in an Ethernet OAM network having multiple levels of OAM domains. An Alarm Indication and Suppression (AIS) frame is generated by a Maintenance Intermediate Point (MIP) node upon detecting a fault condition in a first OAM domain, which is transmitted to one or more Maintenance End Points (MEPs) of the first OAM domain. Upon receiving the AIS frames, the MEP nodes are operable generate another AIS frame for propagating to an adjacent higher level second OAM domain. Responsive to the AIS frame from the lower level first OAM domain, any alarms caused in the second OAM domain due to the fault condition in the first OAM domain are suppressed.

The capability for modifying parameters of a wireless access node may include detecting a trigger event associated with the wireless access node, modifying a signal-to-interference-and-noise ratio (SINR) threshold of the wireless access node responsive to the trigger event, modifying a call admission control (CAC) threshold of the wireless access node based on evaluation of a parameter associated with modification of the SINR threshold of the wireless access node, and further modifying the CAC threshold of the wireless access node based on evaluation of a parameter associated with modification of the CAC threshold of the wireless access node.

Abstract: A load threshold for a first carrier of a base station is set based on quality of service (QoS) classes for applications using the first carrier. Load balancing between the first carrier and one or more second carriers is performed based on the load threshold.

Abstract: Various methods are provided to address the need for improved load balancing. In a one method, a packet loss is determined (101) for traffic sent between a first network node and a second network node. The determined packet loss is then used to determine (103) whether to perform load balancing. In another method, a first network node receives a request from a neighboring network node for a current loading status of the first network node. The first network node sends to the neighboring network node an indication of a backhaul loading level of the first network node.

Abstract: An idle mode load balancing capability enables balancing of idle mode wireless devices across wireless carriers in order to ensure that the possibility of congestion on any given wireless carrier is reduced or even minimized when idle mode wireless devices become active. The idle mode load balancing may be performed for wireless carriers by determining relative numbers of idle mode wireless devices on the wireless carriers and performing idle mode load balancing for the wireless carriers based on the relative numbers of idle mode wireless devices on the wireless carriers. The relative number of idle mode wireless devices on a wireless carrier may be determined based on a change in load on the wireless carrier during the observation period, which may be determined based on an observed change in load on the wireless carrier and a load correction associated with session terminations on the wireless carrier.

Abstract: A client selects a first quality level from a plurality of quality levels used to encode segments of video content for transmission over an air interface in a wireless communication system. The first quality level is selected based upon an indication of a location of the client and an indication of congestion in the wireless communication system. The client transmits a request for a first segment of the video content encoded at the first quality level.

Abstract: A capability for handling network connection changes during adaptive bitrate streaming is provided. A method includes receiving a request for a change associated with a network connection of a client device where the network connection of the client device is configured to support delivery of a content item to the client device using an adaptive bitrate streaming process of the client device, and delaying the change associated with the network connection of the client device based on a state of the adaptive bitrate streaming process. A method includes detecting that a chunk of a content item, requested by an adaptive bitrate streaming process of a client device via a network connection of the client device, has been received at the client device, and delaying a request for a next chunk of the content item based on a state of a change associated with the network connection of the client device.

Abstract: Systems and methods are provided for adjusting Radio Resource Control (RRC) timers in a Radio Access Network (RAN). The system manages radio communications between a mobile device and a base station, and further transitions the mobile device between Radio Resource Control (RRC) states based upon application-layer data traffic for the mobile device and a timer value. Additionally, the system determines an overhead load based on network-layer signaling events associated with at least one RRC transition for the mobile device, and determines a bearer load based on the application-layer data traffic for the mobile device. Based upon the overhead load and the bearer load, the system adjusts the timer value.
