Abstract

The invention discloses a vehicle location information transmission method based on a relay transmission node, comprising: collecting vehicle location information by a vehicle-mounted mobile terminal and monitoring system information sent by a base station; monitoring the system information sent by a base station by a relay transmission node; In response to monitoring the system information sent by the base station, the relay transmission node sends a random access preamble to the base station; in response to receiving the random access preamble, the base station sends a random access response to the relay transmission node; in response to After receiving the random access response, the relay transmission node sends an RRC connection establishment request message to the base station on the resource indicated by the uplink authorization; in response to receiving the RRC connection establishment request message, the base station sends the RRC connection establishment request message to the relay transmission node Establishment completion message; in response to monitoring the system information sent by the base station, the vehicle-mounted mobile terminal sends a cache status report to the relay transmission node; the relay transmission node judges the transmission mode of the relay transmission node.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a method and system for transmitting vehicle location information based on a relay transmission node. Background technique [0002] The Internet of Vehicles is an important specific application in the 5G communication network. Major communication technology companies (such as Ericsson, Japan's DoCoMo, Huawei, ZTE, Qualcomm, Intel, etc.) have proposed a large number of issues related to the Internet of Vehicles in the recent 3GPP meeting. technology. [0003] The prior art CN105516214B discloses a method and device for information reporting and resource allocation in a vehicle networking system. It is used to solve the problem of high probability of collision between existing node devices. The resource allocation method includes: the network side equipment allocates subframe resources for the node equipment that initially accesses the cell, and notifies the ...
