Abstract

The invention discloses a random access optimization method and device of power IOT (Internet of Things) service. The random access optimization method of power IOT service provided by the invention is based on a service driving granularity random access new mechanism, and comprises the steps that by aiming at periodic and power predicating service, noncompetitive random access sequences are reserved in advance and are distributed; channel resources are correspondingly accessed; the service access period and time delay requirements are guaranteed; by aiming at sudden service with sudden performance and different time delay sensitive levels, a proper scale of competitive random access resources are provided for terminal competitive random access; the carrying capability of the power IOT oneach kind of service is optimized; the conflict probability of random access of massive power IOT equipment is reduced; the time delay of various types of service of the power IOT is effectively reduced; the differential QoS requirement of various types of service of the power IOT is better met.

Description

Technical field [0001] The present invention relates to the field of Internet of Things communication, in particular to a random access optimization method and device for power Internet of Things business. Background technique [0002] With the development of the smart grid, especially the power communication system, the online monitoring of equipment in the power system, smart inspection, advanced measurement and power services, electric vehicles and charging piles, distribution network automation and other grid end services are unifiedly connected , Dig deeper into the value of data, and the demand for forming a power Internet of Things is becoming more and more urgent. [0003] Random Access is the first step for terminals in LTE and NB-IoT networks to transmit data. The physical random access channel (PRACH) is an important channel in the system for the terminal to access the system. Random access usually includes competitive random access and non-competitive random access. I...
