Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0034] Such as Figure 1-2 As shown, a cell-to-cell handover method of a cellular-VANET heterogeneous network comprises the following steps:

[0035] (1) The cell edge vehicle initiates a handover assistance request;

[0036] (2) Select a collaborative node;

[0037] (3) The coordination node initiates a channel access request, and the base station allocates a channel;

[0038] (4) The received data is merged between the base stations, and the edge vehicles access the channel;

[0039] (5) End the assisted cell handover to the cell edge vehicle.

[0040] Specifically, in the above method,

[0041] (1) The cell edge vehicle initiates a handover assistance request:

[0042] The operating path of the vehicle is limited to travel along the road, which prevents certain variables re...

Abstract

The invention discloses an inter-cell switching method of a cellular-VANET heterogeneous network. The method comprises the steps of: (1), initiating a switching assistance request by a cell edge vehicle; (2), selecting a cooperative node; (3), initiating a channel access request by the cooperative node, and allocating a channel by a base station; and (4), carrying out received data merging between base stations, and realizing accessing of the edge vehicle to the channel. According to the inter-cell switching method provided by the invention, the vehicle in a switching process communicates with the base stations of a source cell and a target cell through assistance of other vehicles in a vehicle self-organizing network, the vehicle keeps communicating with the base stations all the time in the switching process, the data loss is avoided, and the relatively high data transmission speed can be kept.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a downlink communication technology of a VANET (vehicle ad hoc network) heterogeneous network, in particular to a cell-to-cell switching method of a cellular-VANET heterogeneous network. Background technique [0002] When a vehicle moving at high speed is handed over between cells, the traditional method is to compensate the high-speed movement of the vehicle, but the compensation method may not be able to achieve the desired effect in most cases. packet, data transfer rate drops, etc. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a cell-to-cell handover method for a cellular-VANET heterogeneous network for the scenario where a vehicle runs to the cell edge of a cellular network in a cellular-VANET (Vehicle Ad Hoc Heterogeneous Network), and needs to perform handov...
