Abstract: Systems and methods for providing random access in a cellular communications network are disclosed. In general, the cellular communications network is an Orthogonal Frequency Division Modulation (OFDM) based cellular communications network (e.g., a 3GPP LTE cellular communications network) or similar multi-subcarrier based cellular communications network.

Abstract: Dynamic reporting rates for a log management system are adaptively allocated. Each individual controller node device of plurality of controller nodes is initially allocated an EPS rate limit for submitting event records to a log management system (e.g., an SIEM log management system) out of a licensed EPS rate.

The individual EPS rate limit for at least one collector node is adjusted in real-time for a specific controller node based on under usage by other collector nodes. Another technique is to prioritize or weight events causing the surge to determine adjustments to EPS rate.
