Abstract: In systems and methods of random access preamble selection, a first plurality of random access preambles and a second plurality of random access preambles are stored at an access node. A random access channel request is received from a wireless device at the access node, the random access channel request comprising an application type of an application running on the wireless device, and a network load, a priority class of the wireless device, and a mobility of the wireless device are determined. When the first plurality of random access preambles is not exhausted, the network load meets a load criteria, the priority class of the wireless device meets a priority criteria, the mobility of the wireless device meets a mobility criteria, and the application type of the application meets an application criteria a random access preamble is assigned to the wireless device from the first plurality of random access preambles.
