Problems solved by technology

On the one hand, at present, most of the distribution of vehicle traffic is randomly allocated by operators, without considering the specific use of traffic by users. The traffic is randomly allocated by the network, which makes the distribution of vehicle traffic limited by the 4G network; on the other hand, it is impossible for operators to provide unlimited traffic for car owners. When many car owners use traffic, they will also specify the traffic in consideration of the cost limit upper limit of
Therefore, the allocation of vehicle traffic is limited by various constraints
[0003] At present, the random allocation of vehicle traffic is difficult to provide users with a more optimized traffic allocation plan, and the efficiency of vehicle traffic allocation is low, so that user satisfaction cannot be optimized

[0069] This embodiment provides a vehicle traffic distribution method, such as figure 2 shown, including:

[0070] Step S10: Construct the vehicle traffic distribution satisfaction function according to the allocated traffic numbers of different types of vehicle traffic.

[0071] In this step, the vehicle traffic distribution satisfaction function includes:

[0072] Among them, f(X) is the satisfaction function of vehicle traffic allocation; wi represents the weight of the i-th type of vehicle traffic; ki represents the satisfaction parameter of the i-th type of vehicle traffic; wi and ki are based on the historical usage of vehicle traffic by different owners The statistical value obtained; xi represents the number of traffic allocated by each vehicle traffic; X represents the vehicle traffic distribution scheme.

Embodiment 3

[0091] This embodiment provides an on-vehicle traffic allocation method, which is different from the on-vehicle traffic allocation method in Embodiment 2 in that there are multiple restricted conditions for on-vehicle traffic allocation. Correspondingly, the on-vehicle traffic distribution restriction function includes multiple. Lagrange operators include multiple. The vehicle traffic distribution objective function includes:

[0092] L(X,λ)=f(X)-[λ 1 g 1 (X)+λ 2 g 2 (X)+…+λ k g k (X)];

[0093] Among them, L(X,λ) is the objective function of vehicle traffic allocation; g 1 (X), g 2 (X)...g k (X) assigns a restricted function vector to a group of vehicle traffic; λ 1 , lambda 2 ...λ k is a set of Lagrangian operator vectors, a set of Lagrangian operator vectors [λ 1 , lambda 2 ...λ k ] means f(X) of the optimal solution and a set of restricted function vectors [g 1 (X), g 2 (X)...g k (X)] gradient ratio, which is expressed by a set of vehicle flow distribution...

Abstract

The invention provides a vehicle flow distribution method and system. The vehicle traffic allocation method includes: constructing the vehicle traffic allocation satisfaction function according to the allocated traffic numbers of different types of vehicle traffic; constructing the vehicle traffic allocation limited function according to the limited conditions of vehicle traffic allocation; The traffic distribution satisfaction function and the vehicle traffic distribution restriction function construct the vehicle traffic distribution objective function; the gradient method is used to calculate the optimal solution of the vehicle traffic distribution objective function; the optimal solution is the optimal scheme of the vehicle traffic distribution. The on-vehicle traffic allocation method can obtain the optimal scheme of on-vehicle traffic allocation, so that the user's on-vehicle traffic allocation can be optimized, and then the user's satisfaction can be optimized. In this method, it is possible to avoid traversing all vehicle traffic distribution schemes, thereby improving the distribution efficiency of vehicle traffic.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and system for distributing vehicle traffic. Background technique [0002] With the increasing types of in-vehicle networking devices, the demand for in-vehicle traffic is gradually increasing. On the one hand, at present, most of the distribution of vehicle traffic is randomly allocated by operators, without considering the specific use of traffic by users. The traffic is randomly allocated by the network, which makes the distribution of vehicle traffic limited by the 4G network; on the other hand, it is impossible for operators to provide unlimited traffic for car owners. When many car owners use traffic, they will also specify the traffic in consideration of the cost limit upper limit. Therefore, the distribution of vehicle traffic is limited by various constraints. [0003] At present, the random allocation of vehicle traffic is difficult to pr...
