  • Patent number: 10079943
    Abstract: System and method for detecting anomalies in the recorded consumption of data volume and charging of data services in a communication network is described. Data records for each session may be captured from multiple sources. The data records may comprise parameters indicating usage volume pertaining to services being consumed for each session. Further, the data records may be aggregated and reconciled to detect volume gap in each session. Each session may be categorized into a session category based upon the detection of the volume gap. The data records may further be enriched by tagging each data record with the session category. The data records enriched may then be aggregated across the parameters. Finally, a root-cause parameter for the volume gap pertaining to each session may be identified by computing a total volume, a total volume gap and a probability of gap root-cause for each parameter using the aggregated data records.

  • Patent number: 9788321
    Abstract: The invention provides method and apparatus for resource allocation in wireless communication network. The method comprises: determining each UE in each cell of a cluster to be a CE UE or CC UE according to pilot signal strength reported by the UE; dividing available frequency band into two non-overlapping frequency bands of CE frequency band and CC frequency band based on the number of CC UEs and the number of CE UEs in the cluster; assigning non-overlapping portion from the CE frequency band to each cell based on at least one number associated with CE UEs in each cell; assigning at least one resource block (RB) from the CC frequency band to each CC UE in each cell; and assigning at least one RB from the assigned non-overlapping portion from the CE frequency band to each cell of the cluster to each CE UE in the corresponding cell.
