Abstract

The invention provides a random access method and a terminal, and relates to the technical field of the communication. The random access method comprises the following steps: receiving random access mechanism configuration information sent by a base station, wherein the random access mechanism configuration information comprises random access type and random access time frequency resource information corresponding to the random access type, the random access type comprises a first random access mechanism and / or a second random access mechanism; and executing the random access process of the first random access mechanism or the second random access mechanism according to the random access mechanism configuration information. Through the above scheme, the terminal performs the random accessprocess according to the configuration information by acquiring the random access mechanism configuration information configured for itself by the base station, so that the terminal can perform the selection of the random access mechanism according to the own service situation; the problems of control plane processing delay, high data plane collision probability and low partial data resource use ratio are solved, and the reliability of the random access is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a random access method and a terminal. Background technique [0002] The existing Long Term Evolution (LTE) protocol adopts a four-step random access mechanism, such as figure 1 As shown, the main implementation process of the four-step random access mechanism is: [0003] Step 11, the terminal sends a random access preamble (Random Access Preamble, Msg1 message) to the base station; [0004] Step 12, the base station feeds back a Random Access Response (Random Access Response, RAR, Msg2 message) to the terminal; [0005] Step 13, the terminal sends a scheduling-based transmission message (Scheduled Transmission, Msg3 message), the Msg3 message includes layer 2 / layer 3 (L2 / L3) random access information; [0006] Step 14, the base station sends a contention resolution message (Contention Resolution, ie Msg4 message) to the terminal. [0007] For the uplink mul...
