Abstract

The present invention provides a random access method and a device. The method comprises: a primary UE sending a layer 2/layer 3 message to a network-side device in a group random access time window, wherein the layer 2/layer 3 message comprises transmission requirement instruction information; the primary UE and a secondary UE using a same random access resource, and the secondary UE avoiding sending a sequence code to the network-side device in the group random access time window; and in the group random access time window, the primary UE receiving an access completion notification message sent back by the network-side device after receiving the lay 2/layer 3 message, so as to complete a random access process. The technical scheme in the present invention reduces random access time of the UE.

Description

technical field [0001] The present invention relates to communication technology, in particular to a random access method and equipment. Background technique [0002] In a wireless communication system, due to limited available resources, corresponding resources are allocated to a user equipment (User Equipment, referred to as UE for short) only when it needs to communicate. When the UE initiates communication, the random access process is performed first. During the random access process, the UE will obtain the time, frequency, and code resources required to carry out services. [0003] In a Long Term Evolution (LTE for short) system, the random access process is mainly divided into two methods based on contention and based on non-contention. In the contention-based random process, the base station (eNB) will indicate in the broadcast message the access resource information that the cell is allowed to initiate random access, and the UE randomly selects an allowed sequence ...
