Embodiment Construction

[0229] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

[0230] The random access process is divided into two categories: a competitive random access process and a non-competitive random access process. For the contention random access process, multiple terminals (UE: User Equipment) share the same random access preamble format (PRACH preamble format: Physical Random Access Channel preamble format) and / or PRACH time domain a...

Abstract

The invention provides a random access resource determination method, a random access resource allocation method, a terminal and network side equipment, and belongs to the technical field of wirelesscommunication, one method comprises the following steps: determining a random access resource according to a first identifier; or, determining a first random access resource set according to the firstidentifier, and randomly selecting random access resources from the first random access resource set, wherein the first identifier is determined according to at least one of the identifier of the terminal, the flight identifier of the flight where the terminal is located currently, the route identifier of the route where the terminal is located currently and the route identifier of the route where the terminal is located currently. According to the invention, the random access success rate of the ATG airborne terminal can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a random access resource determination method, allocation method, terminal and network side equipment. Background technique [0002] With the development of the aviation industry and Internet technology, the demand for ground-air interconnection applications is becoming more and more urgent. Through the ground-air interconnection, passengers can access the Internet on the plane as if they were on the ground, and enjoy various Internet application services. Operators, airlines and all parties in the industry can also provide value-added services based on the ground-air interconnection technology. [0003] Ground-to-air (ATG: air-to-ground) service can provide airline passengers with in-flight entertainment, in-flight office and customized services, and has a wide range of industry application prospects, which can be summarized into two types: video image ret...
