摘要： A random access method based on priority is disclosed. A priority-based random access method for use in a random access method supporting emergency communication including selecting, by a user equipment (UE), a random access slot corresponding to priority of the UE, among several random access slots to which at least two priorities are allocated, selecting an arbitrary sequence by the UE, and transferring the selected sequence to a base station via the selected random access slot. The method minimizes a UE access delay time requesting emergency communication by assigning priority to resources, and is able to reduce an amount of wasted resources by effectively distributing resources to not only a high-priority UE but also a low-priority UE according to individual situations.
