CPC Code(s): H04W74/0833
Abstract: a method for controlling a maximum number of random access (ra) preambles for a network node to handle concurrently in a first cell in a wireless communications network. a runtime parameter associated with the network node restricts the network node to handle at most a first maximum number of ra preambles concurrently. the network node monitors load characteristics associated with the first cell. when the load characteristics fulfil a triggering condition, the network node selects a second maximum number of ra preambles to be handled concurrently. the second maximum number is selected such that a probability value fulfils a threshold. the probability value is associated with a probability that ra preambles that are to be concurrently transmitted in the first cell will exceed the second maximum number of ra preambles. the runtime is adjusted to restrict the network node to handle at most the second maximum number of ra preambles concurrently.
