Abstract: Excessive signaling by devices against a radio access network (RAN) can be detected and mitigated. A security management component (SMC) can determine whether a total number of control signals received by a base station from devices satisfies a threshold total number of control signals indicative of excessive signaling. If so, SMC can identify a device associated with the base station based on analyzing communication conditions associated with the device. SMC can determine whether to classify the device as an excessive signaling device based on whether the number of control signals received from the device by the base station satisfies a threshold number of control signals indicative of excessive signaling. If so, SMC can determine the device is an excessive signaling device. In response, SMC can perform or facilitate performing a mitigation action to mitigate excessive signaling or can generate statistics relating to the excessive signaling.

Abstract: Network planning based on collected crowd-sourced access point quality and selection data can optimize access point frequency and/or bandwidth selection. A cloud-based application can be utilized in conjunction with a mobile device to build a database of access point quality and thresholds suitable for real-time and other jitter-sensitive services. The mobile device jitter measurements and selection thresholds can be collected at a cloud platform, which creates an access point performance and selection threshold profile from which the network can facilitate access point frequency and/or bandwidth selections.
