  • Patent number: 10045016
    Abstract: A method of managing lip synchronization error in a multimedia content delivery network includes identifying a video packet and an audio packet associated with the video packet and determining a synchronization offset between the audio and video packets at a first monitoring point in the network. The audio and video packets are then detected at a second monitoring point in the network and a second synchronization offset is determined. When a delta between the first synchronization offset and the second synchronization offset exceeds a threshold, lip synchronization error information may be automatically recorded and/or reported to a service provider and corrective action may be taken if potential sources of the lip synchronization error are within the domain of the service provider. The video packet may be identified by a timestamp within the packet and the audio packet may be identified by audio data within the audio packet.

  • Patent number: 8768339
    Abstract: A method and apparatus for enabling a wireless communication service provider to remotely provide wireless network service outage and/or degradation detection, isolation, and restoration relating to a base station are disclosed. For example, the method detects a wireless service problem, and isolates the wireless service problem to a base station of a plurality of base stations of the wireless communication network, wherein the wireless service problem comprises a wireless service degradation. The method then performs a recovery task remotely on the base station to address the wireless service degradation.

  • Patent number: 8660026
    Abstract: A method, computer readable medium and apparatus for performing mapping management are disclosed. For example, the method monitors network performance measurements of long term evolution mobility elements, monitors a class type and a bandwidth type of long term evolution interfaces, determines if an impairment state is detected based upon the monitoring network performance measurements and the monitoring the class type and the bandwidth type, determines if the impairment state is due to a class of service and a quality of service mismatch and reconfigures the quality of service if the impairment state is due to the class of service and the quality of service mismatch.

  • Patent number: 8549358
    Abstract: A method, computer readable medium and apparatus for performing session establishment management. For example, the method detects an evolved packet system establishment success rate that is measured over a predefined period of time falling below a predefined threshold, and performs, via a rule management server, an analysis on a bearer portion. The method then associates, via the rule management server, a root cause that contributed to the evolved packet system establishment success rate falling below the predefined threshold.
