[0035] figure 2 A schematic flowchart of the first embodiment of the message receiving method provided by the present invention, as shown in figure 2The first embodiment of the shown message receiving method includes the following steps:

[0036] In step S101, the regional server receives a service message query request sent by a terminal, and initiates a terminal service message query request to the central controller according to the service message query request.

[0037] Specifically, in the message receiving method provided by the present invention, when switching to the service channel, the terminal sends a service message query request to the regional controller to check whether any service message is temporarily stored for continued reception, and the regional control The device initiates a query request for the service message of the terminal to the central controller.

[0038] Step S102, the regional server receives the service message transmission notification s...

Abstract

The invention provides a message receiving method. When a service channel is monitored through a terminal, the message receiving method includes: a region server receiving service message query requests sent by the terminal and starting terminal service message query requests to a central control unit according to the service message query requests; the region server receiving service message transmission notification sent back by the central control unit, the service message transmission notification carrying a temporary service message identifier and a temporary regional controller identifier of the terminal, a region controller starting service message forwarding requests according to the temporary service message identifier and the temporary region controller identifier, receiving the temporary service messages sent back by the temporary region controller and sending the temporary service messages to the terminal. By the arrangement, the terminal is capable of receiving the complete and consistent service messages, and service quality and use effectiveness of Internet of Vehicles are improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a message receiving method and device. Background technique [0002] In the technology of the Internet of Vehicles, the MAC layer technology can be divided into two categories: one is the control access protocol represented by time division multiple access (TDMA), and the other is the carrier sense multiple access (CSMA) The representative random access protocol. In the TDMA protocol, each vehicle node is assigned a fixed time slot to send data. The advantage is that the delay is small, and there will be no collision of multiple nodes accessing at the same time. However, due to the fast movement of vehicle nodes in the Internet of Vehicles, The network topology changes frequently, so that the allocated time slots for updating vehicle nodes are also quite frequent, which brings huge network overhead. At present, the CSMA protocol has been widely used in IEEE...
