Abstract: Compatibility and/or compliance testing for a wireless cellular network may be performed using a testing system that includes a device that implements multiple base stations in a single hardware device. Additionally, a network simulation server may simulate a core portion of the wireless cellular network. Test cases, such as test cases defined using a scripting language, may be received and the test cases may be interpreted to obtain configuration information for the testing system. Based on the configuration information, the base stations and the simulated network devices may be initially configured. After configuration, and based on the test case, a UE may be controller to interact with the simulated network in a manner implements the desired compatibility and/or compliance tests.

Abstract: A recursive algorithm may be applied to group cells in a service network into a small number of clusters. For each of the clusters, different regression algorithms may be evaluated, and a regression algorithm generating a smallest error is selected. A total error for the clusters may be identified based on the errors from the selected regression algorithms and from degrees of separation associated with the cluster. If the total error is greater than a threshold value, the cells may be grouped into a larger number of clusters and the new clusters may be re-evaluated. A key performance indicator (KPI) may be estimated for a cell based on a regression algorithm selected for the cluster associated with the cell. A resources may be allocated to the cell based on the KPI value.

Abstract: A device may collect network performance data associated with a user equipment of a network. The network performance data may include information associated with a plurality of performance indicators of the network. The device may process information associated with a first portion of the plurality of performance indicators to determine a first performance category experience score, and information associated with a second portion of the plurality of performance indicators to determine a second performance category experience score. The device may process the first performance category experience score and the second performance category experience score to determine a network experience score. The device may determine whether the network experience score satisfies a threshold value. The device may perform one or more actions based on determining that the network experience score satisfies the threshold value.

Abstract: A method to enhance a subjective quality of experience for an application may include receiving network performance data, the data representing at least one observable application characteristic, and the subjective quality of experience (QoE) survey data. The method may further include generating at least one perception model which relates the data representing at least one observable application characteristic and the network performance data, and determining a QoE model which relates the subjective QoE survey data and the data representing at least one observable application characteristic. The method may further include inverting the at least one perception model and the QoE model to obtain a relationship between network performance parameters and the at least one observable application characteristic, and adjusting network parameters based on the at least one inverted perception model and inverted QoE model.

Abstract: A non-intrusive method of determining whether a mobile device is transmitting through a Wi-Fi router or a cellular network is described. The method includes monitoring messages relating to a wireless network. A subset of the messages including Create Session Request, and IMSI/MDN are received and later a subset of the messages including Delete Session Request, and the IMSI/MDN are received. The combination of the sets of received messages is used to determine whether the mobile device is transmitting through the Wi-Fi router or the cellular network, specifically based on the Create Session Request and the Delete Session Request.
