Detailed description of the invention
Below in conjunction with the accompanying drawings, provide presently preferred embodiments of the present invention, and be described in detail, make to be better understood when this
Bright function, feature.
As it is shown in figure 1, the vehicular ad hoc network gateway device of the present invention includes being communicatively coupled to user terminal 1 and LTE successively
Wireless router 2, radio reception device 3 and aerial array 4 between base station, wireless router 2 includes the user being sequentially connected in series
Access Control module 21 and wireless routing module 22, radio reception device 3 includes Ethernet interface 31, the data stream being sequentially connected in series
Distribution module 32 and LTE network module 33.Wherein, user terminal 1 includes mobile phone, flat board etc.；User access control module 21 is used
In the bandwidth resources that the quantity and unique user terminal that limit access user terminal take, and in the Mean Speed of user terminal
Forbid when dropping to default minimum speed limit that new user terminal accesses, thus ensure the Consumer's Experience of each user；Without circuit
It is used for realizing wireless access while multiple user terminal 1 by module 22；Ethernet interface 31 is used for realizing wireless routing module
Data interaction between 22 and data stream distribution module 32；Data stream distribution module 32 is for for by the allocation rule logarithm preset
It is allocated according to stream, thus realizes flow path and the load balancing of online under different scene；LTE network module 33 includes some
The SIM of each operator (such as move, telecommunications and UNICOM), wraps in the transmitting-receiving of LTE frequency range in order to realize user data；LTE base
Station includes mobile base station 51, telecomm base station 52 and UNICOM base station 53, the incoming public network of user data package in order to receiving, thus
Realize the bridge joint between LAN and outside public network in car.The most directly connect owing to user terminal 1 is directly accessed wireless router 2
Enter LTE base station, thus avoid number of users more time group's switching problem of occurring.
In the present invention, above-mentioned allocation rule includes following three kinds of situations:
The first situation, as in figure 2 it is shown, when the user terminal accessed is less than some, use the side dividing equally bandwidth
Formula, makes the transceiving data bag of each user terminal receive and dispatch parallel through whole SIMs, i.e. for each user terminal, uses also
The mechanism of row transmitting-receiving, for single SIM, uses the mode transceiving data bag of time-division for different user.Therefore, at this
In individual application scenarios, incorporate the public-network bandwidth resource of three operators (i.e. move, UNICOM and telecommunications), for unique user eventually
For end, the transmitting-receiving speed of user data package will be that multiple increases along with SIM quantity.In theory, when the number of SIM
When amount is more than or equal to the quantity of user terminal, the transfer rate of system and handling capacity all can obtain lifting.
The second situation, as it is shown on figure 3, understand mobile base station, telecomm base station or UNICOM base station according to driving empirical data
Current signal coverage strength and loading condition, when the signal coverage strength of a certain operator is less than preset strength value or load
More than presetting load value, when its band resource that can provide is less, thus shields the SIM of this operator or limit through phase
The SIM answering operator carries out the user terminal quantity of packet transmitting-receiving, such that it is able to ensure Consumer's Experience on the whole, it is ensured that
Making full use of of band resource.
The third situation, as shown in Figure 4, when the user terminal accessed is more than some, according to by driving experience number
According to the signal coverage strength of current each operator obtained and loading condition, distribute the packet of each SIM transmitting-receiving quantity and
Type of service, specifically, according to the type of service of packet, the priority of each type of service is distributed different weights because of
Son, utilizes operational authority repeated factor to be weighted, and obtains the method for salary distribution of various flows, and the packet of different business leads to the most at last
Cross different Business Streams and be allocated transmitting-receiving.
Additionally, be different from common gateway device, the aerial array 4 of gateway device of the present invention uses adaptive array
Row, its can according to empirical data through section adjust antenna parameter and data stream transmitting distribution in good time, it is achieved data pass
Defeated distributes rationally and load balancing, antenna configures the enhanced terminal data card of respective operator, sends receipts concurrently
The user data package arrived, promotes message transmission rate.
In the present embodiment, gateway device also includes the control management being connected with wireless router 2 and radio reception device 3
Platform 6, in order to the ruuning situation of wireless router 2 and radio reception device 3 to carry out real-time checking and analyzing, and can select
Select different user's matching strategies and adjust the performance of equipment.
In sum, as long as being configured with the vehicular ad hoc network gateway device of the present invention ON TRAINS, crew and taking advantage of in car
Visitor can access the Internet by WIFI in car, the demand surfed the Net in meeting car.
Above-described, only presently preferred embodiments of the present invention, it is not limited to the scope of the present invention, the present invention's is upper
State embodiment can also make a variety of changes.The most every claims according to the present patent application and description are made
Simply, equivalence change with modify, fall within the claims of patent of the present invention.Being of the most detailed description of the present invention
Routine techniques content.
