The present disclosure provides a random access method and device, and a storage medium. The random access method comprises: receiving resource configuration information, the resource configuration information being used for configuring resources in a specified random access resource pool corresponding to at least one network slice; determining a first random access resource on the basis of slice information of a target network slice and the resource configuration information, the target network slice being a network slice for initiating random access by the user equipment (UE); and initiating random access on the basis of the first random access resource. According to the present disclosure, the possibility of a collision between a UE using a certain slice service and other UEs during random access is reduced, and the success rate of random access of a UE is improved, such that the UE can quickly complete random access to obtain a desired slice service.
