Abstract

An embodiment of the invention provides a random access method and user equipment. The random access method includes that the user equipment acquires a persistent level broadcast by a base station; the user equipment acquires a persistent value according to the persistent level and generates a random value between 0 and 1 if an access service class of the user equipment is the highest class, and the persistent value is larger than a persistent value which is acquired by the user equipment according to the persistent level when the access service class of the user equipment is not the highest class; and the user initiates random access to the base station if the generated random value is smaller than the obtained persistent value.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a random access method and user equipment. Background technique [0002] In a communication system, before initiating a communication service, a user equipment needs to obtain a dedicated radio resource allocated by a network by initiating a random access. The channel used by the user equipment to initiate random access (that is, the random access channel) is a shared channel. If more than one user equipment initiates random access through this channel, random access conflicts will occur, resulting in random access failure. . In order to reduce the probability of user equipment random access process conflicts, before the user equipment initiates random access, if the access service class (Access Service Class, ASC) of the user equipment is not the highest priority (for example: ASC=1, 2 , 3, 4, 5, 6 or 7, etc.), the user equipment can first generate a rand...
