Embodiment 1

[0035] figure 1 It is a flowchart of a data transmission method provided by an embodiment of the present invention. The execution subject of this embodiment is the user equipment, see figure 1 , the example includes:

[0036] 101. The user equipment acquires local public point-to-multipoint radio bearer parameters allocated by the base station;

[0037] 102. The user equipment sends data to the base station according to the local public point-to-multipoint radio bearer parameters allocated by the base station, so that the base station forwards the data to the user equipment in the coverage area of ​​the base station.

[0038] By adopting the technical solution of the present invention, the user equipment does not need to interact with the core network, and can use the local public P2M RB parameters allocated by the base station to quickly perform data transmission, simplify the bearer establishment process, make the transmission delay the shortest, and solve the problem of t...

Embodiment 2

[0040] figure 2 It is a flowchart of a data transmission method provided by an embodiment of the present invention. The execution subject of this embodiment is a base station, and the base station may specifically be an eNB (evolved Node B, evolved base station) or an RNC (Radio Network Controller, radio network controller) in a WCDMA network, see figure 2 , the example includes:

[0041] 201. The base station allocates local public point-to-multipoint radio bearer parameters for the user equipment;

[0042] 202. The base station sends the point-to-multipoint radio bearer parameters to the user equipment;

[0043] 203. When receiving data sent by the user equipment, deliver the data to the user equipment in the coverage area of ​​the base station according to a preset modulation and coding scheme.

[0044] With the technical solution of the present invention, the user equipment does not need to interact with the core network, and can use the local public P2M RB parameters...

Embodiment 3

[0046] Figure 3a It is a flowchart of a data transmission method provided by an embodiment of the present invention. The road traffic system in this embodiment includes user equipment A, user equipment B, user equipment C, and a base station. In this embodiment, user equipment A is the current fault vehicle, and user equipment A, user equipment B, and user equipment C are simultaneously In the coverage area of ​​the base station, an example is used for description. Referring to Fig. 3, this embodiment includes:

[0047] 301. User equipment A receives local public P2M RB parameters broadcast by the base station;

[0048] Different from the prior art, in the LTE system of this embodiment, local public P2M RB parameters are pre-configured, the local public P2M RB parameters are specifically public local P2M RB parameters, and the public local P2M RB parameters are used to configure the base station In the way of sending the uplink data of the user equipment in the coverage ar...

Abstract

The invention discloses a data transmission method, user devices, a base station and a system, and belongs to the technical field of communication. The data transmission method includes the steps of enabling the user devices to obtain local-common-point-to-multipoint radio bearer parameters distributed by the base station, and enabling the user devices to send data to the base station according to the local-common-point-to-multipoint radio bearer parameters distributed by the base station so as to enable the base station to forward the data to the user devices in the covering area of the base station. The data transmission method further includes the steps of enabling the base station to distribute the local-common-point-to-multipoint radio bearer parameters to the user devices, enabling the base station to transmit the local-common-point-to-multipoint radio bearer parameters to the user devices, and when the data transmitted by the user devices are received, enabling the base station to issue the data to the user devices in the covering area of the base station according to a preset modulation coding manner. The data transmission method, the user devices, the base station and the system solve the problems of the informed delay uncertainty and the excessively large delay of a warning message in the prior LTE technology.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a data transmission method, user equipment, base station and system. Background technique [0002] In the intelligent transportation system, one type of application is emergency warning, including: early warning of accidents ahead, early warning of road traffic ahead, etc. When a UE (User Equipment, user equipment) such as a vehicle fails or collides, it sends an alarm signal to the intelligent transportation system, and the system notifies other nearby UEs. This type of application requires the end-to-end delay of the alarm signal to be at the level of 100 milliseconds. To enable more vehicles to implement risk avoidance, improve travel safety, and reduce loss of life and property. In the existing LTE (Long Term Evolution, Long Term Evolution) system, after a vehicle collides, it needs to first establish a connection with the network side through a complex signal...
