Abstract

The invention discloses a vehicle position information transmission method based on a relay transmission node. The method comprises the steps that a vehicle-mounted mobile terminal collects vehicle position information and monitors system information sent by a base station; the relay transmission node monitors system information sent by the base station; in response to the monitored 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, by the base station, a random accessresponse is sent to the relay transmission node; in response to receiving the random access response, by the relay transmission node, an RRC connection establishment request message is sent to the base station on the resource indicated by the uplink grant; in response to the received RRC connection establishment request message, the base station sends an RRC connection establishment completion message to the relay transmission node; the monitored system information sent by the base station is responded and a cache state report is sent to the relay transmission node by the vehicle-mounted mobile terminal; and 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 ...
