Title: RANDOM ACCESS METHOD, APPARATUS AND SYSTEM
Abstract:
Provided in an embodiment of the present invention are a random access method, apparatus and system, relating to the field of communications, and realizing timely access of a terminal to a beam to improve the success rate when the terminal accesses a network. A solution provided by the embodiment of the present invention comprises: a terminal receives multiple signals sent by a first access device on multiple beams; the terminal determines a beam with the strongest signal amongst the multiple beams and generates a preamble signal of the beam with the strongest signal; and the terminal sends the preamble signal of the beam with the strongest signal to the first access device, so that the first access device identifies, according to the received preamble signal, the beam that the terminal selects to access. The present invention is used for random access.
