Embodiment Construction

[0073] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] The present invention aims at the problem that the existing random access message 2 or message 3 sending method cannot ensure early processing of high-priority services for terminals in RRC connection state, and provides a random access method, terminal and network equipment.

[0075] like figure 1 As shown, the embodiment of the present invention provides a random access method applied to a terminal, including:

[0076] Step 101, acquiring the trigger reason of the random access process;

[0077] Step 102, if the trigger cause is a preset trigger cause, then send a message 3 including the first wireless network temporary identifier RNTI to the network device;

[0078] It should be noted that the message three including the first RNTI is us...

Abstract

The invention provides a random access method, terminal and network equipment, and relates to the technical field of communication. The random access method is applied to a terminal, and includes: acquiring a trigger cause of a random access process; if the trigger cause is a preset trigger cause, sending a message 3 including a first wireless network temporary identifier RNTI to a network device; wherein , the message three is used to indicate the preset status of the terminal; the preset status includes: services with the first preset priority, logical channels with the second preset priority, and services with the third preset priority At least one item in the logical channel group. In the above solution, according to the triggering cause of the random access process, a message including the first RNTI indicating the preset state of the terminal is sent to the network device, and by reporting the state of the terminal to the network device, high-priority services are guaranteed to be processed first , to ensure the reliability of network communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access method, terminal and network equipment. Background technique [0002] With the evolution of the fifth generation (5Generation, 5G) system standard, the physical layer determines to introduce a new radio network temporary identity (Radio Network TemporyIdentity, RNTI) for the user equipment (UserEquipment, UE, also known as the terminal), which is used to indicate the new Modulation and Coding Scheme (MCS) table, the new MCS table is generally used for Ultra-reliable low-latency communications (Ultra-reliable low-latency communications, URLLC) but not limited to URLLC. [0003] For contention-based random access, the whole process includes 4 steps: [0004] Step 1. Message 1, ie Msg1: Send preamble [0005] The base station is responsible for configuring the preamble and the Physical Random Access Channel (PRACH) resource used to send the preamble,...
